Sentiment analysis neural network github

A neural network consists of layers. Every neural network has an input layer (size equal to the number of features) and an output layer (size equal to the number of classes). Between these two layers, there can be a number of hidden layers. The sizes of the hidden layers are a parameter. In this case we’ve only used a single hidden layer.

A Context-based Neural Network Model for Twitter Sentiment Classiﬁcation The proposed model is shown in Figure 2, which has two main components. The left component is a local-feature sub neural network, using only local information from the target tweet itself, while the right component is a contextualized feature sub network.

This paper describes our deep learning system for sentiment analysis of tweets. The main contribution of this work is a new model for initializing the parameter weights of the convolutional neural network, which is crucial to train an accurate model while avoiding the need to inject any additional features. Briefly, we use an unsupervised neural language model to train initial word embeddings ...

1https://github.com/Artaches/SSAN-self-attention-sentiment-analysis-classification The above can be summarized by the following equations. Given a query q, values (v 1;:::;v n), and keys (k 1;:::;k n) we compute output z: z= Xn j=1 j(v j) (1) P j = expf(k j;q) n i=1 expf(k i;q) (2) j is computed using the softmax function where f(k i;q) is the compatibility score between k
