2.4.1 pipeline对象实例化参数 model(PreTrainedModel或TFPreTrainedModel)— 管道将使用其进行预测的模型。 对于 PyTorch,这需要从PreTrainedModel继承;对于 TensorFlow,这需要从TFPreTrainedModel继承。 tokenizer(PreTrainedTokenizer) — 管道将使用 tokenizer 来为模型编码数据。此对象继承自PreTrainedTokenizer。 modelcard(st...

Classification Tasks That Leverage Embeddings Inthe previous example, we used a pretrained task-specific model for sentiment analysis. However, what if we cannot find a model that was pretrained for this specific task? Do we need to fine-tune a representation model ourselves? The answer is no!
model = TextRNN(vocab_size, embedding_dim, hidden_dim, num_classes) criterion = nn.CrossEntropyLoss() optimizer = torch.optim.Adam(model.parameters()) # Train the model for epoch in range(num_epochs): for inputs, labels in train_data: ...
You can use pretrained text classification models from ArcGIS Living Atlas of the World or train custom models using the Train Text Classification Model tool. The input to the Classify Text Using Deep Learning tool is a feature class or table containing the text to be classified. The input ...
为了解决RNN、CNN两个模型各自存在的问题,论文Recurrent Convolutional Neural Networks for Text Classification提出了一种叫做RCNN的模型架构, 用双向循环结构来尽可能多地获取上下文信息,这比传统的基于窗口的神经网络更能减少噪声,而且在学习文本表达时可以大范围的保留词序。
classic, so they may be good to serve as baseline models. each model has a test function under model class. you can run it to performance toy task first. the model is independent from data set. check here for formal report of large scale multi-label text classification with deep learning...
