Coefficient, and k < 1；
During training pattern, in order to which the training speed of balance model has selected relatively suitable study with loss
Rate, but the loss of training set may decline and just no longer decline to a certain extent, at this time can be by suitably reducing learning rate
One step reduces loss, but the decline of learning rate can extend the training required time.Therefore, which uses learning rate gradually
The method of decaying finds new balance between training time and reduction loss, and appropriate by setting maximum number of iterations
The controlled training time；
After training reaches maximum number of iterations, judge whether the penalty values of the sorter network model are less than preset threshold；
If it is, illustrating that sorter network model has reached convergence, repetitive exercise is completed；
Otherwise, continue using sorter network model described in the training set repetitive exercise, until the sorter network model
Penalty values are less than preset threshold, that is, train until the convergence of sorter network model.

It sets identical；Each node of full articulamentum is connected with upper one layer of all nodes, comprehensive for feature that front is extracted
Altogether.
Step 2.6: being followed by the full articulamentum of N number of branch in the second full articulamentum, the respectively full articulamentum 1 of branch, branch is complete
The full articulamentum n of articulamentum 2 ... branch, connect after each full articulamentum of branch again one it is softmax layers corresponding, as corresponding
Taxon, attribute classification output of the output of taxon as final every class characteristics of image, respectively taxon 1,
Taxon 2 ... taxon n.
In the present invention, after multiple convolutional layers and pond layer, 2 full articulamentums is connected to and N number of branch connects entirely
Layer.Each neuron in full articulamentum is connect entirely with all neurons of its preceding layer.Full articulamentum can integrate volume
With the local message of class discrimination in lamination or pond layer.In order to promote the network performance of convolutional neural networks, Quan Lian
The excitation function of each neuron of layer is connect using ReLU function.The output valve of each full articulamentum of branch is delivered to one
Softmax layers are classified.Softmax layers of algorithm can be understood as normalizing, and such as current picture classification has x kind, that process
Softmax layers of output is exactly the vector of x dimension.First value in vector is exactly the probability that current image belongs to the first kind
It is worth, second value in vector is exactly that the sum of vector that current image belongs to that this x of the probability value ... of the second class is tieed up is 1.
Step 3: the training of non-motor vehicle multi-tag sorter network, step 3 correspond to the instruction of above-mentioned sorter network model
The training set is inputted into the sorter network model in white silk and is iterated trained step, by each grouping sheet in training process
Loss of the penalty values weighted sum of member as sorter network, repetitive exercise to model are restrained, and the process of specific steps three is as follows:
Step 3.1: according to the LMDB data set arranged in step 1, first calculating the mean value file of training dataset, save
For the format of .binaryproto file, and refer to the position for determining binary system mean value file in training network；
Step 3.2: using the training method of finetune, using the trained weight on ImageNet public data collection
File initializes current network carry out portion hierarchical weight, and other layers are carried out with the mode of random initializtion, institute as above
It states, in this example, using weight file trained on ImageNet public data collection to convolutional layer, pond layer, first
Full articulamentum and the second full articulamentum initialization, and random initializtion is carried out to the full articulamentum of branch and taxon, it is random first
Beginningization can initialize weight using normal distribution, however, the present invention is not limited thereto；

When, setting crowd size batch_size is 32, and initial learning rate is 0.001, and maximum number of iterations is 200000 times, using step
Mode carry out learning rate modification in the training process, learning rate is multiplied by 0.9 after every iteration 1000 times, using stochastic gradient descent
Algorithm training data sets 10000 preservation primary network models of every iteration；Stochastic gradient descent algorithm can be accelerated to update each
A layer of weight file and biased data, referring in each iterative process at random here, sample will be upset at random, upset
Parameter caused by can effectively reducing between sample updates cancellation problem.In most basic stochastic gradient descent algorithm, parameter
Each step is updated by subtracting its gradient, and large-scale machine learning task, stochastic gradient descent algorithm are showed
Performance is very considerable.
When training, training sample and label are inputted into the network of initialization, calculate the penalty values of each softmax layers of input
Weighted sum is as final loss, and each softmax layers of weight is 1/N, but invention is not limited thereto, specific weight value
Distribution, which can according to need, to be configured.By two steps of continuous propagated forward and backpropagation, repetition training makes
Losing in training process constantly reduces, until reaching maximum the number of iterations；
After training is completed every time, using the network model of preservation as the pre-training model of next iteration training, avoid
Occur the loss of model data in the training process, continue to train, after training reaches maximum the number of iterations, judges that loss is
It is no to reach preset threshold hereinafter, if it is, end training, otherwise continues training until loss reaches preset threshold hereinafter, instruction
Practicing convergence then terminates to train.
Step 4: non-motor vehicle multi-tag image classification, step 1 and step 3 are all non-motor vehicle multi-tag images
The preparation process of sorter network model, and step 4 corresponds to above-mentioned steps S100~step S400, i.e., using trained
The step of sorter network model classifies to image, specifically, the process of step 4 are as follows:
Step 4.1: the test data pre-processed being sent into trained sorter network model, extracts non-motor vehicle image
Feature corresponds to step S100 and S200；
Step 4.2: the non-motor vehicle characteristics of image extracted being sent into softmax layers, N number of feature is exported and belongs to specified genus
Property in each classification probability, take the classification of maximum probability in each attribute as the classification results of the attribute, by N group identification
Classification results merge into final output list of categories, that is, correspond to step S300 and S400.
Due to the structure for the sorter network model that the present invention uses, non-motor vehicle image can be disposably obtained in multiple categories
Property under classification results, and operated without individually constructing disaggregated model for each attribute, therefore by above-mentioned step, i.e.,
The quick multi-tag classification of non-motor vehicle image can be achieved.
