The invention provides a text classification model training method,
system and product based on mixed sampling, and relates to the technical field of
deep learning, and the method comprises the steps: predicting the probability that data in an unlabeled text
data set belongs to each text category through a text classification model, and obtaining a prediction result; determining a labeling progress; in the early stage of the labeling progress, based on a prediction result, sampling a subset by a class balance sampling strategy, and labeling to obtain a labeled subset; in the middle stage of the labeling progress, based on a prediction result, a subset is sampled through an uncertainty and diversity mixed sampling strategy, and a labeling subset is obtained through labeling; at the later stage of the labeling progress, based on a prediction result, sampling a subset by an edge sampling strategy or an uncertainty and diversity mixed sampling strategy, and labeling to obtain a labeled subset; and when each
annotation subset is obtained, constructing a corresponding augmented
training set, and training the text classification model for one time by using the constructed augmented
training set. The objective of the invention is to improve sample labeling and model training efficiency.
