Bag of Tricks for Efficient Text Classification prediction。一般来说tag的数量都很大,相当于类别数量巨大的分类问题。这种情况下,普通的softmax就很慢了。这里作者还是用的word2vec中的内容。在word2vec中是预测词,词的数量巨大。这里是...word2vec中CBOW模型的一个变形,CBOW是上下文单词的词向量平均去预测中心...

Note the main reason why PyTorch merges the log_softmax with the cross-entropy loss calculation in torch.nn.functional.cross_entropy is numerical stability. It just so happens that the derivative of the loss with respect to its input and the derivative of the log-softmax with respect to its...

Intuition:Consider a binary classification problem trained using softmax loss function. LetW₁ andW₂be the linear classifiers of class1and2respectively. A data pointxᵢis predicted as class 1 if the feature vectorfᵢfollows: Condition for xᵢ to belong to class 1 ...
We will use BERT - Google's recently announced NLP approach for transfer learning for sentiment classification stock news sentiment extraction. Fourier transforms - Along with the daily closing price, we will create Fourier transforms in order to generalize several long- and short-term trends. Using...
with the main difference being attaching fully connected layers followed by a softmax layer to the base language model to solve the multi-classification problem. We employed an innovative data augmentation technique to generate a vast amount of high-quality training data that is required to ensure ...

Since the 2012 Imagenet competition, the use of AI has increased in many ways. In the past, various computer vision algorithms were used for face, people, and image detection. Over time, those algorithms have been replaced by neural networks with functions such as classificati...
