Problems solved by technology
Most of the data enhancement schemes in the prior art are controlled by manually setting parameters, and the manual design of data enhancement operations and parameters often requires a lot of engineering experience to adjust the parameters, and the calculation cost is large and the processing speed is slow.
At the same time, inappropriate parameter adjustment will bring noise data to the training of the neural network, which in turn will bring negative effects and reduce the performance of the model.

The embodiment of the invention discloses a data enhancement method and device, a storage medium and electronic equipment; target enhancement strategy search is carried out by determining an enhancement strategy search space comprising a plurality of enhancement strategies, and the execution sequence of the plurality of searched target enhancement strategies is determined. The method also includes determining at least one enhancement operation with the corresponding attribute value corresponding to each target enhancement strategy in a preset enhancement operation set; executing each target enhancement strategy in sequence according to the execution sequence of each target enhancement strategy and the included enhancement operation, and performing data enhancement on the original data. According to the embodiment of the invention, automatic data enhancement can be realized, the calculation overhead is reduced in the data enhancement process, the processing speed is improved, and noise is prevented from being generated in the data enhancement process based on manual parameter setting.
Description
technical field [0001] The present invention relates to the field of computer technology, in particular to a data enhancement method, device, storage medium and electronic equipment. Background technique [0002] At present, the rapid development of deep learning has accelerated the development of artificial intelligence technology. The multi-layer neural network in deep learning can extract relevant semantic features through a large amount of training data. However, overfitting occurs when there is insufficient training data, causing the model to fail to generalize to undiscovered examples. For the above-mentioned problem of insufficient training data, it is usually solved by data enhancement, that is, new data is obtained by converting the original data set. Most of the data enhancement schemes in the prior art are controlled by manually setting parameters, while manually designing the operation and parameters of data enhancement often requires a lot of engineering experi...
