Abstract

The invention proposes a model training method and device based on machine learning, and the method comprises the steps: extracting samples from a sample set according to the sampling probability of each sample in the sample set, so as to generate a training set for this time; employing the training set for the training of a machine learning model; carrying out the estimation of the trained machine learning model, so as to obtain the classification accuracy of each sample in the training set; and adjusting the sampling probability of each sample in the training set according to the classification accuracy. The adjusted sampling probability is used for generating a training set for the next training. The method can achieve the adaptive adjustment of the sampling probability of each sample, improves the classification accuracy of an important sample and solves a problem that a neural network in the prior art is not accurate in sample classification.

Description

technical field [0001] The present invention relates to the technical field of machine learning, in particular to a model training method and device based on machine learning. Background technique [0002] With the development of artificial intelligence technology, intelligent home appliances have gradually become a development trend, and users have higher and higher demands for intelligent home appliances (such as washing machines). Applied in the research of smart home appliances. [0003] In the relevant deep learning technology, when using sample data for neural network training, the probability of occurrence of each sample is regarded as the same, which may easily lead to inaccurate classification of samples by the obtained neural network, and some classification accuracy is high, while some case of lower accuracy. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. ...
