CLASSIFICATIONANNOTATIONSGiven a set of labels, multi-label text classification (MLTC) aims to assign multiple relevant labels for a text. Recently, deep learning models get inspiring results in MLTC. Training a high-quality deep MLTC model typically demands large-scale labeled data. And comparing ...
2.基于Rnn的模型把text看作单词序列并且捕获单词的独立性和text的结构(RNN-based models view text as a sequence of words,and are intended to capture word dependencies and text structure) 3.基于CNN的模型训练识别text的模式,像是关键短语在文本分类任务上(CNN-based models are trained to recognize patterns...
For classification tasks where there can be multiple independent labels for each observation—for example, tags on an scientific article—you can train a deep learning model to predict probabilities for each independent class. To enable a network to learn multilabel classification targets, you can ...
