and identifying the audio data to be identified according to the audio identification optimization model to obtain an identification result of the audio data.
It should be understood that data cleansing refers to the last procedure to find and correct recognizable errors in a data file, including checking data consistency, processing invalid and missing values, and the like.
And optimizing the audio recognition model according to the preset adjusting parameters to obtain an audio recognition optimization model.

Optionally, as an embodiment of the present invention, the process of respectively performing feature extraction on each target audio data to obtain corresponding feature points includes:
respectively carrying out dimensionality reduction on the target audio data to obtain a plurality of audio data subjected to dimensionality reduction;
and respectively extracting the features of the plurality of audio data subjected to dimension reduction by using a preset spectrogram to obtain a plurality of feature points.
It should be understood that in the field of machine learning and statistics, dimensionality reduction refers to the process of reducing the number of random variables under certain defined conditions to yield a set of "uncorrelated" principal variables. The dimension reduction of the data can save the storage space of a computer on one hand, and can eliminate the noise in the data and improve the performance of a machine learning algorithm on the other hand; the root of data dimension reduction: the data dimensionality is reduced, and the data after dimensionality reduction can represent the original data as much as possible.
It should be understood that, the LDA linear discriminant analysis algorithm is used to perform dimension reduction on a plurality of target audio data, so as to obtain a plurality of audio data after dimension reduction.
Specifically, a plurality of target audio data are projected on a low dimension respectively, so that an audio text is reduced from thousands of dimensions to k dimensions, the intra-class variance of the projected target audio data is minimum, and the inter-class variance is maximum; and compressing the target audio data which is reduced to the new feature space, and reserving information as much as possible to obtain a plurality of audio data after dimension reduction.
It should be understood that a Spectrogram (Spectrogram), whose abscissa is time, ordinate is frequency, and whose coordinate points are voice data energy, is a display image of time-series-related fourier analysis, which can reflect the transformation of the music signal spectrum with time. Because the three-dimensional information is expressed by adopting the two-dimensional plane, the size of the energy value is expressed by the color, and the deeper the color, the stronger the voice energy for expressing the point is.
The spectrogram displays a great deal of information related to the characteristics of the music signal, such as the change of frequency domain parameters such as formants, energy and the like along with time, and has the characteristics of a time domain waveform and a spectrogram. That is, the spectrogram itself contains all the spectral information of the music signal without any processing, so that the information of the spectrogram about the music is lossless.
The patterns in the spectrogram comprise transverse lines, random lines, vertical strips and the like, the transverse lines are black bands parallel to the time axis and are formants, the corresponding formant frequency and bandwidth can be determined according to the frequency and bandwidth corresponding to the transverse lines, and whether the transverse lines appear in the spectrogram of a section of audio is an important mark for judging whether the spectrogram is voiced sound or not is judged; the vertical bars are narrow black bars perpendicular to the time axis, each vertical bar corresponding to a fundamental tone, the start of a stripe corresponding to the start of a voiceprint pulse, the distance between stripes representing the fundamental tone, the denser the stripes representing the higher the frequency of the fundamental tone.
In the above embodiment, the dimension reduction processing on the target audio data is performed respectively to obtain the reduced audio data, the preset spectrogram is used to extract the features of the reduced audio data to obtain the feature points, so that the main features having a greater influence on the sound stability early warning of the screw water-cooling unit can be obtained, the calculation amount of the subsequent steps is reduced, and the subsequent support vector machine can obtain a higher accuracy rate only by using less training data.
Optionally, as an embodiment of the present invention, the training model according to the feature point data set to obtain an audio recognition model includes:
s1: randomly dividing the feature point data set into a feature point training set and a feature point testing set;
s2: constructing a model based on a support vector machine algorithm to obtain a support vector machine structure;
s3: inputting the feature point training set and the feature point testing set into the support vector machine structure together to search for an optimal recognition hyperplane, so as to obtain an optimal recognition hyperplane, and obtaining a support vector set and VC (virtual component interconnect) credibility according to the optimal recognition hyperplane;
s4: carrying out discrimination processing on the support vector set according to the VC credibility to obtain a discrimination function, and generating a training model according to the discrimination function;
s5: and carrying out model screening processing on the training model according to the feature point training set and the feature point testing set to obtain an audio recognition model.
It should be understood that, since the feature point data set is randomly divided into the feature point training set and the feature point testing set each time, the random proportion of each time is different, and the train _ test _ split function may be invoked for random division.
The Support Vector Machine (SVM) is a supervised learning algorithm, the SVM theory provides complexity for avoiding a high-dimensional space, an inner product function (namely a kernel function) of the space is directly used, and a solving method under the condition of linear divisibility is utilized to directly solve a decision problem of the corresponding high-dimensional space.
It should be understood that the VC credibility is the VC dimensional confidence or confidence risk, and the VC dimension is a measure for the function class, which can be simply understood as the complexity of the problem, and the higher the VC dimension is, the more complex a problem is. For example: many classification functions can easily achieve 100% accuracy on a sample set, but are confusing (i.e., so-called poor generalization ability, or poor generalization ability) when classified in reality. In this case, a classification function is selected that is complex enough (i.e. its VC dimension is high) to accurately remember each sample, but uniformly classify the data outside the sample in error.
Specifically, the feature point training set and the feature point testing set are input into the structure of the support vector machine, and the sample feature space of the support vector machine is used to find out the optimal identification hyperplane of each class of feature sample and other feature samples, so as to obtain the support vector set representing each class of sample and the corresponding VC credibility, form the discriminant function for distinguishing each feature, and obtain the training model.

Optionally, as an embodiment of the present invention, the process of step S5 includes:
s51: inputting the feature point training set into the training model according to preset iterative training times to perform iterative training to obtain a first detection model;
s52: inputting the feature point test set into the first detection model for detection to obtain a first accuracy, and judging whether the first accuracy reaches a preset expected value, if so, taking the first detection model as an audio recognition model, then performing optimization processing on the audio recognition model, and if not, executing the step S53;
s53: inputting the feature point test set into the training model for iterative training according to the preset iterative training times to obtain a second detection model;
s54: inputting the feature point training set into the second detection model for detection to obtain a second accuracy;

Preferably, the preset expected value is 0.90.
In the above embodiment, a higher recognition accuracy can be ensured through the obtained first detection model and the second detection model, and an audio recognition model meeting expectations is obtained, when the first accuracy of the first detection model does not reach an expected value, the second detection model is obtained through training of the feature point test set, and the second accuracy is obtained through detection by using the feature point training set, which is equivalent to exchanging the training set and the test set, and the recognition model meeting expectations can be further ensured to be obtained, so that the accuracy of detecting audio data to be recognized by the audio recognition model meeting the expected value can be always kept at a higher level, and the stability and reliability of audio recognition are improved.
