LSTM Text Classification Using Pytorch

  • Next, we convert REAL to 0 and FAKE to 1, concatenate title and text to form a new column titletext (we use both the title and text to decide the outcome), drop rows with empty text, trim each sample to the first_n_words , and split the dataset according to train_test_ratio and train_valid_ratio.
  • In the forward function, we pass the text IDs through the embedding layer to get the embeddings, pass it through the LSTM accommodating variable-length sequences, learn from both directions, pass it through the fully connected linear layer, and finally sigmoid to get the probability of the sequences belonging to FAKE (being 1).
  • Once we finished training, we can load the metrics previously saved and output a diagram showing the training loss and validation loss throughout time.
  • This tutorial gives a step-by-step explanation of implementing your own LSTM model for text classification using Pytorch.

How (NOT) To Predict Stock Prices With LSTMs

  • Not so recently, a brilliant and ‘original’ idea suddenly struck me — what if I could predict stock prices using Machine Learning.
  • The following piece of code downloads stock price data for Reliance over 15 years with a resolution of 1 day and stores it in a pandas dataframe.
  • Let’s fix our problem statement now — the LSTM model shall see the close prices for the last 10 days (called the time_step) and predict the close price for the next day.
  • But in a practical scenario, the test data will be in real-time, so you won’t know the minimum or maximum or average values beforehand!
  • Finally, let’s structure the data so that our LSTM model can easily read them.
  • The simple sequential model has an LSTM layer followed by a dropout (to reduce over-fitting) and a final dense layer (our output prediction).

LSTM Gradients

  • Based on h_t-1 (previous hidden state) and x_t (current input at time-step t), this decides a value between 0 and 1 for each value in cell state C_t-1.
  • Now these two values i.e i_t and c~t combine to decide what new input is to be fed to the cell state.
  • At each time-step the previous cell state (C_t-1) combines with the forget gate to decide what information is to be carried forward which in turn combines with the input gate (i_t and c~t) to form the new cell state or the new memory of the cell.
  • Now i hope the basic cell structure of a LSTM cell is clear and we can proceed to the derivation of equations which we will use in our implementation.
