本文简要介绍python语言中 torch.nn.Embedding.from_pretrained 的用法。 用法: classmethod from_pretrained(embeddings, freeze=True, padding_idx=None, max_norm=None, norm_type=2.0, scale_grad_by_freq=False, sparse=False) 参数: embeddings(Tensor) -FloatTensor 包含嵌入的权重。第一个维度作为 num_...
有监督的算法在embedding效果较好的时候可以超越无监督算法,但如果把训练时间考虑进去的话,存在比较大的overhead My 2 cents: 对从头开始进行全链路的迭代的算法选型有一定指导意义,对于主要结论也许可以这么解释:embedding类比weak learner的产出,graph model做ensemble,只有weak learner效果过bottleneck之后ensemble才有效果?

Pre-trained vectors trained on part of Google News dataset (about 100 billion words). The model contains 300-dimensional vectors for 3 million words and phrases. The phrases were obtained using a simple data-driven approach described inthis paper ...
Deep learning (DL)-based predictive models from electronic health records (EHRs) deliver impressive performance in many clinical tasks. Large training cohorts, however, are often required by these models to achieve high accuracy, hindering the adoption o
