Comparative Study. Literature involving these datasets mainly focus on non-deep learning based approaches. Thereby, we compare our results with some popular conventional learning techniques. For the k-NN-ngram experiments, the number of nearest neighbours k was set to 5. For the mentioned datasets, conventional models outperform our baseline Bi-LSTM model, however upon instance infusion the deep learning based model is able to achieve competitive performance across all datasets. Moreover by instance infusion the simple bi-LSTM model approaches the classical models in performance on News20 and BBC Sports dataset, whereas on BBC Dataset the proposed instance infused bi-LSTM model beats all the mentioned models.
