Machine learning model training method, intention recognition method, related device and equipment

The embodiment of the invention discloses a machine model training method, an intention recognition method and related devices in the field of artificial intelligence. The method comprises the following steps: training a capsule network model according to a training sample, wherein the training process comprises the steps of iteratively adjusting a current weight coefficient corresponding to a first prediction vector according to the similarity between a first activation vector and the first prediction vector, wherein the first activation vector is the weighted sum of a plurality of predictionvectors, and represents the probability that the intention of the training text is predicted as a first real intention; and the first prediction vector represents a contribution of the first semanticfeature to the first real intent. Furthermore, the weight coefficient corresponding to the prediction vector with the large similarity with the first activation vector is increased; therefore, the semantic features corresponding to the prediction vectors with the large similarity with the first activation vectors are screened out, the semantic features corresponding to the prediction vectors withthe small similarity with the first activation vectors are filtered out, the semantic features with the high correlation degree are screened out to form the intention, and the accuracy of intention recognition of the model is improved.
