LSTM with Attention by using Context Vector for Classification task

The implementation of Attention-Based LSTM for Psychological Stress Detection from Spoken Language Using Distant Supervision paper. The idea is to consider the importance of every word from the inputs and use it in the classification. Then the importance scores are normalized through the softmax layer. The weighted sum of the score and hidden states in every time-step is used for the classification.
