5. Make necessary assumptions if required. For further clarification, you can contacts the
TAs from : http://172.16.1.5/~asif/CS566-AML/
The assignment targets document classification of the BBC news dataset. The dataset/files has
already been converted to a single csv file for easier processing. The dataset has 2 features,
first is the ‘Article’ which is the input for the task while the second ‘Class’ features classifies the
article into one of 5 classes : business, entertainment, politics, sport and tech . You can find
more info at http://mlg.ucd.ie/datasets/bbc.html

What you have to do:
1. Implement the LSTM and GRU models for the sequence classification task. Implement
the models with minimum hidden layers and also keep all hyperparameters exactly the
same for both the models. Run the model for 5 epochs. Use the seed value of ‘1’ for
consistent results. Compare the two models on the basis of performance metrics
(accuracy, precision, recall) and number of parameters in each model. Write your results
in a separate file when submitting. Steps are
a. Preprocess/clean the data(remove stopwords etc.)
b. The input to LSTM/GRU will be the articles, with tokens represented with a 100
dimension vector each(ie. Embedding size = 100).
c. Make sure to pad the input to the maximum article length.
d. Use 70:10:20 split for training, validation and testing
e. Use of dataloader is optional.
2. The general consensus for LSTM/GRU for classification tasks is to use ReLU for hidden
layers and sigmoid/softmax for final output. Run your model(created above) with different
activation layers(Relu, softmax/sigmoid, tanh, elu, leaky ReLU) at their appropriate
positions and calculate the performance change for each combination. Specify which
works best in case of LSTM/GRU. Write your results in a separate file when submitting.
3. Evaluation:
a. Perform 3-fold cross-validation
b. Compute the overall accuracy for each of the 3-folds (for all the classes together)
c. Compute the class-wise accuracy for each of the 3-folds
