As described in detail below.
Please refer to fig. 1, which is a flowchart illustrating an embodiment of the method of the present application. The method for quickly creating the model project in the machine learning platform comprises the following steps:
step 101: and creating a machine learning model project operating environment.
The model project refers to a data workflow or data application which is built on a machine learning platform by a machine learning platform user and consists of a plurality of or a series of components. Model items are also referred to as computational model items, and also include experimental model items created temporarily or over time to verify a particular function. The examples of the present application will be described with experimental model items as examples. The rules among the existing data can be found through the model items, and finally the model items reflecting the rules are created.
The machine learning execution environment is a virtual environment in the machine learning platform for creating and executing model items, under which the model items can be created and executed.
The method for creating the machine learning model project operating environment comprises the following steps:
step 101-1: a model project panel is created on the machine learning platform.
The model item panel refers to a machine learning model item execution environment in the form of a panel on which the model item can be created and executed. Unlike traditional model item interfaces in machine learning platforms, the model item panel may also have components stored on it in a directly visible form. The model item panel may be created on the machine learning platform by clicking on a button on the machine learning platform that creates the model item panel. The user can name, rename and the like the created model project panel.
The model item panel is provided with a scroll bar so as to facilitate viewing and operating the whole model item panel.
A plurality of the model project panels may be created simultaneously.
A plurality of model projects can be created and run simultaneously on the same model project panel; and when the performance of the page is deteriorated due to the simultaneous operation of a plurality of model items, the capacity can be expanded on the back-end server according to the number of users and the use frequency of the components.
The user may also select whether to save the model item and the generated model item that have been successfully run on the model item panel, and when selecting to save the model item and the generated model item, may set saving parameters such as a saving name, a saving location, and a saving life cycle of the model item or the generated model item.
Step 101-2: assigning a model item panel identification code to the created model item panel.
The model item panel identification code refers to a code used to identify the model item panel. The model project panel identification code corresponds to the model project panel one by one and is a unique code.
When the creation of the model item panel on the machine learning platform is successful, a daemon will assign the model item panel identification code to the created model item panel.
Fig. 8 shows a schematic diagram of a panel created on a machine learning platform. As shown in FIG. 8, the experiment model project panel created is shown as the "experiment run panel" in the figure. The panel area below, the experimental model project can be created by pulling the component and performing the simulation. The experimental model project (the experiment is abbreviated in fig. 8 to 11) refers to a data workflow or data application set up by a machine learning platform user; the user needs to establish an experiment example and then build a data flow on the experiment panel.
Please continue to refer to fig. 1, step 102: adding components required by a model project to the machine learning runtime environment.
Specifically, in this step, components are added to the model project operating environment according to the requirements of the model project or the project and the like.
The component refers to an operation unit which can be called and executed on the machine learning platform and is used for representing various algorithms or data sources. Such as data import and export, data processing, data analysis, model project training, or prediction.
The component representing the algorithm is an algorithm component, the algorithm component is provided with a parameter configuration column for configuring parameters of each algorithm during operation, and the algorithm component is provided with input and output buttons for connection among the algorithms and output and viewing of operation results of the algorithms.
The component representing the data source is a data source component which is mainly used for setting the table name, once the table name is set by the data source component, the system reads data of the corresponding table name from the background database and provides the data for subsequent algorithm components.
The components include the algorithm component and the data source component.
The method for adding the components required by the model project to the machine learning running environment comprises the following steps:
step 102-1: adding components to the model project panel. The components may be components of the same model project, or components of different model projects. The present embodiment will be described by taking the example of adding the same item model component. However, it should be noted that the present application is not limited to this, and components of different model items may be added simultaneously or sequentially, and in the subsequent step, input and output links are established according to the sequence of the components belonging to the same model item.
Adding the dragged components to the model item panel by dragging the corresponding components in the component column one by one into the model item panel.
Step 102-2: inserting the added attribute information of the component into a model project panel information table;
the attribute information comprises the identification code of the model project panel where the added component is located, the name of the added component and the position information of the added component in the model project panel.
The model item panel information table is a database table for recording the attribute information of all the components in the model item panel.
When the component is successfully added into the model item panel, the background program inserts the attribute information such as the model item panel identification code of the added component, the component name and the position information in the model item panel into a model item panel information table to record the added component.
Step 103: and establishing input and output links for the components required by the model item according to the sequence set by the model item to create the model item.
The components required by the model project refer to the sum of the algorithm component and the data source component required by the model project to be created.
The sequence set by the model items refers to the sequence of the execution steps of the model items.
The input and output link refers to a connecting line between an algorithm component and a data source component which are required by the model project and are carried out according to the sequence of the steps of the model project. I.e. input-output channels for data or commands between building blocks.
The method for establishing the input and output links of the components required by the model project according to the set sequence of the model project to create the model project comprises the following steps:
step 103-1: and distributing model item names and model item codes for the model items to be operated.
The model item to be run is the created model item in which all components required for the model item are connected in the order set by the model item, or the created model item in which some of the components required for the model item are connected.
The model item code refers to a code for identifying the model item. The model item codes correspond to the model items one by one and are unique codes.
And for each model item to be run, automatically and randomly allocating a model item name and a corresponding model item code to the background program when the background program is created.
Step 103-2: the components required for the model project are selected.
The selecting of the components required by the model items means that the components required by the selecting of the two model items are connected according to the set sequence of the model items.
And the two connected components required by the model item are a parent component and a child component in sequence according to the set sequence of the model item.
The components required for selecting a model item include selecting from the components added to the machine learning model item execution environment, or from the components already present in the model item execution environment, or from the components already used by other model items. Or in a certain project model project, components are simultaneously selected from all or any two of the foregoing to meet the requirements of the model project or project.
Step 103-3: judging whether the selected component contains a father node or a parallel node or not, and automatically distributing a model project name and a model project code when the selected component does not contain the father node or the parallel node;
each component in the model project forms a model project node, referred to as a node for short; the father node is the last model project node of the selected model project node; the parallel nodes are the model item nodes for which the selected model item nodes have the common parent node.
Determining whether the selected component includes a parent node or a parallel node means determining whether the parent component in step 103-2 includes a parent node or a parallel node.
If the parent component does not contain the parent node or the parallel node, the child component is connected with the parent component, a new model project is created, and at the moment, a background program automatically and randomly allocates a model project name and a model project code for the created new model project;
if the parent component contains the parent node or the parallel node, the fact that the child component is connected with the parent component is that the component is added to the model item to be operated containing the parent component, and at the moment, a new model item is not created.
Step 103-4: inserting model item information and the model item panel identification code into a model item information table;
the model item information includes the model item name, the model item code, components required for the model item, and attribute information of the components required for the model item.
The model item information table is a data table for recording the model item information of all the model items to be operated and the model item panel identification codes of the model items.
When a new model item is created in step 103-3, and the created new model item also becomes a model item to be run, the model item information to which the created new model item belongs and the model item panel identification code in which the model item is located are also inserted into the model item information table.
Step 103-5: and inserting each node information constituting the model item into a node information table.
The node information includes location information of the node, parent node and child node information related to the node.
And the child nodes of the nodes are the model project nodes at the next level of the model project nodes.
The node-related parent nodes refer to all parent nodes of the model project node.
The child nodes related to the nodes refer to all child nodes of the model project node.
The node information table is a data table for recording the node information of all the nodes included in all the model items to be operated.
When a new model item is created in the step 103-3, the node information of each model item node constituting the model item is inserted into the node information table at the same time as the step 103-4 is performed.
Step 103-6: establishing data or command input and output links among components required by model items according to sequence set by the model items
The step is to repeat the four steps 103-2, 103-3, 103-4 and 103-5, and sequentially connect all algorithm components and data sources required by the model item according to the sequence set by the model item, thereby creating the model item.
Step 104: carrying out parameter configuration on components required by the model project;
the method for configuring the parameters of the components required by the model project comprises the following steps:
step 104-1: parameter information of algorithm components required for configuring the model project.
And opening the parameter configuration column of the algorithm component required by the model item to be subjected to parameter configuration, and selecting the parameters required by the operation of the algorithm for configuration. For example, if a certain algorithm node is a random forest algorithm node, the parameters of the number of trees, the tree depth, the training column, the target column and the like are configured.
Step 104-2; and inserting the parameter information, the node identification code, the node name and the model item identification code into a node parameter table.
The parameter information of the algorithm component required for the model project includes parameter names and parameter configuration values of all parameters thereof.
The node parameter table is a data table for recording the node identification code, the node name, the associated model item identification code of the node and the parameter information of the component corresponding to the node contained in the model item.
After the parameter configuration of the algorithm component required by the model project is completed through the step 104-1, the background program of the step 104-2 is automatically executed.
Fig. 9 shows the flow of node connection and the contents of the related parameter information table, and the contents of the above steps 103 and 104 can also refer to fig. 9.
Through the steps, the creation of the model item is completed, and further, the model item can be simulated and checked through simulating and operating the model item, so that whether the built model item can achieve the expected purpose or not can be achieved. Please continue to refer to fig. 1.
Step 105: and running the created model item.
The method for operating the created model item comprises the following steps:
step 105-1: selecting a model item to be run, and starting to run the model item.
After the user selects the model item to be run in a frame selection mode, the model item is started to run by pressing a button for running the model item preset on the machine learning platform.
Because the machine learning platform supports the simultaneous operation of a plurality of model items, a user can simultaneously select a plurality of model items to be operated so that the plurality of selected model items can be operated simultaneously.
If the user has not boxed the model item to run, all model items in the machine learning model item runtime environment are selected by default. Of course, the platform may select a default model item mode, for example, it may default to not run any model items when not boxed.
Step 105-2: and reading all the node identification codes in the model item according to the model item identification codes.
When the model item selected in the step 105-1 starts to run, the background program first reads the model item codes of all the running model items, and then reads the node identification codes of all the nodes in the model item corresponding to the model item codes according to the read model item codes.
Step 105-3: sorting the nodes according to the parent-child relationship of the node identification codes in the node table;
next, in the step 105-2, reading all the parent nodes and child nodes of each read node identification code in the node information table to determine the parent-child relationship among all the nodes included in the executed model item, and sorting all the nodes included in the executed model item according to the parent-child relationship.
Step 105-4: and executing the nodes in sequence according to the node sequence.
Then, in the step 105-3, after the all nodes included in the executed model item are sorted, the step is executed.
The method for sequentially executing the nodes according to the node sequence comprises the following steps:
step 105-4-1: for each node, acquiring the parameter information of the node from the node parameter table according to the model project code and the node identification code;
when executing one node, the background program reads the parameter information of the node from the node parameter table according to the executed node identification code and the corresponding model item code.
Step 105-4-2: judging whether the node belongs to the data source node or the algorithm node;
the data source node refers to that a component corresponding to the node is a data source component. The algorithm node means that the component corresponding to the node is an algorithm component. And judging the node as a data source node or an algorithm node according to the node parameter information read from the node parameter table.
Step 105-4-3: when the judgment result is the data source node, acquiring data from a database of a machine learning platform;
and if the judgment result in the step 105-4-2 is the data source node, acquiring data from a corresponding database of the machine learning platform. For a machine learning platform, the intelligent platform is mainly divided into three layers, wherein the first layer is a Web UI interface, the second layer is an IDST algorithm layer, and the last layer is a database platform layer. In the machine learning platform, the step specifically refers to reading table data from a corresponding database.
Step 105-4-4: and when the judgment result is the algorithm node, acquiring the parameter of the node from the node parameter table and executing the algorithm according to the algorithm parameter.
And if the judgment result of the step 105-4-2 is an algorithm node, executing the algorithm corresponding to the algorithm node according to the parameter information of the algorithm node read in the step 105-4-1.
Specifically, the parameter information is spliced into a machine learning command line form according to an agreed format. The background program sends the machine learning command to the database system through the scheduling system, and the database system obtains the storage space where the algorithm is located, the name of the algorithm and the parameter configuration of the algorithm according to the parameters in the analysis machine learning command format. The database system calls a target algorithm in the designated algorithm storage space and executes the algorithm according to the algorithm parameters. And after the algorithm is successfully operated, returning the name of a result table of the algorithm or the name of a generated algorithm model item, wherein the result table is stored in a database item space (simply understood as a database) corresponding to the current system of the user, and the pmml file of the algorithm model item is stored in the ODPS volume designated by the background system.
The algorithm node execution flow chart can refer to fig. 11.
Step 105-5: and after the execution of the model item is finished, inserting model item execution state data into the model item execution state table.
The node execution log table is a database table used for recording the operation condition of the node;
the model item execution state table is a database table used for recording the operation result of the model item of the instrument.
The model item operation result comprises the operation time and the operation result of the model item.
In the step 105-4, each time a node is executed, the daemon inserts a piece of data into the node execution log table to record the execution status of the node.
If the node is successfully executed, recording an execution log of the node;
if the execution of the node fails, recording an execution failure log of the node; meanwhile, the model item corresponding to the node which fails to execute stops running, and the result data of the model item running is inserted into a model item execution state table;
and if all the nodes of the framed model item are successfully executed, the framed model item is successfully operated, and the operation result data of the model item is also inserted into the model item execution state table.
The flow of the experimental model project run can also be seen in fig. 10.

The method for quickly creating a model project according to the present application is described below by using a specific example, as shown in fig. 13, it shows a model project component connection relationship diagram established on a platform by using the method for quickly creating a model project according to the above embodiment. In order to predict haze weather, after weather prediction data are acquired, preprocessing can be performed through a data preprocessing component, model project training is performed on the processed data, the weather conditions are predicted by using the trained model projects and the test data, and prediction results are evaluated. The method comprises the following specific steps: an input data source (a weather prediction data component) is divided into two types of data, namely training data and test data after type conversion (data preprocessing), and the training data are input into two machine learning components, namely a random forest-1 in figure 13 and a logistic regression binary classification (logistic regression binary classification-1 in figure 13), so as to respectively obtain training model items; then, taking the training model items and the split test data as input of a prediction component, and predicting whether weather corresponding to each line of data in the test data is haze weather or not; and evaluating the predicted effect by the evaluation component;
for the haze weather prediction experiment model project, the experiment flow shown in fig. 13 can be established by the method of the embodiment, the components are respectively pulled to the panel according to the experiment requirements, and the connection is established according to the experiment flow, that is, the temporary experiment is established. If only random forests or logistic regression binary component output model items are needed to perform other work, such as model item online deployment and open online weather prediction service, a temporary experiment can be established in a test environment (namely an experiment panel), and a debugging experiment is run to store the experiment model items; meanwhile, which experimental model item is stored can be selected according to model item prediction evaluation results of random forests and logistic regression; the experiment is not required to be established in the test environment, and the experiment parameters can be debugged and the experiment results can be compared; meanwhile, haze weather prediction is carried out in the experiment, and for other two-class prediction, only a data source component needs to be modified, and the rest components in the experiment are shared; the user can modify the experiment according to the quality of the experiment results of the random forest and the logistic regression secondary classification (only the prediction evaluation branch of the random forest or only the prediction evaluation branch of the logistic regression secondary classification is saved) and then the experiment is saved.
In the embodiment of the application, the operating environment for quick creation is created in the machine learning platform, the experimental assembly is placed in the experimental environment, the operation experiment can be simulated in the experimental environment, and the experimental result can be obtained quickly in time. The platform system distributes an identification area (namely a panel with an identification code) for the operating environment, the experiment assembly is built on the panel, and the background records experiment information, parameter information, node information and mutual correlation information through parameter tables with different dimensions. During experiment operation, through the parameter table and the related data and commands, the operation of the experiment can be rapidly and flexibly realized, the components can be reused on the panel, different experiments can use the same component, the component and the related nodes are judged to be called by which experiment through the experiment identification code, and a plurality of experiments can be operated without mutual interference and concurrence.
According to the embodiment of the application, a large amount of time and physical power of a user can be saved, the user only needs to establish a model project trial operation panel when operating the model project, the algorithm components are pulled to the panel, so that various temporary model projects can be formed by using the algorithm components all the time, the model project can be tried to operate, the model project can be debugged and the effect of the model project can be checked in the panel, and whether the model project is stored or not or the model project generated by the temporary model project is stored is selected after the model project is successfully operated. If the user only needs the generated model item to perform subsequent data prediction and other functions, the user only needs to store the model item, does not need to additionally create the model item, and operates the model item to generate the model item. Each time the user wants any model item, only "try running" in the panel is needed.
In addition, after the panels are created in the embodiment of the application, all algorithm components which are possibly used are pulled to the panels, when the number of algorithm components is large, pages are possibly dense and disordered, a user can create a plurality of panels, the identification code of each panel is unique, and the components contained in each panel can be pulled from the component bar at will. At the same time, the "panel" contains a scroll bar so that the panel can present a large area. When a plurality of model projects are operated simultaneously in the same panel, the page performance is possibly poor, so that the rear end of the server can expand the capacity according to the number of users and the use frequency of the components;
in addition, the temporary model project in the application can also store the model project after the trial operation is successful, and a successfully operated model project can be obtained only by setting the name, the storage position and the life cycle of the model project; when only the model item is needed, the user only needs to test and run the corresponding temporary model item once, and complicated processes such as model item building and the like are not needed;
in addition, the algorithm components in the panel are not changed due to success or failure of the operation of the model project, and a user can repeatedly use the algorithm components for many times without pulling from the algorithm component column in the machine learning page.
In addition, the temporary model items can be established in the panel to carry out smoking tests, and in addition, the temporary model items can be established only for producing model item data, preprocessing the model item data, obtaining the model item model items and the like.
In addition, when the algorithm components in the component column are changed, the algorithm components in the panel can be selected to be changed or not, such as updating old algorithm components, adding new algorithm components and the like, and the flexibility is strong.
