Deep learning for feature extraction from incident data

Submitted Apr 12, 2017

Lots of incident data is available in large corporate. However it is Noisy and inaccurate. Classification directly using TFIDF vectorization and machine learning models gives low accuracy. Lots of effort is spent in hand curation of data. Objective is to automatically extract features using deep learning techniques to get a higher lever representation of the text in the incidents. Downstream tasks like classification and clustering will be performed on this space. Presentation will cover the deep learning network architecture of such a system and the results obtained.

• OUTCOMES/CONCLUSION
The participants will be exposed to the concept of Representation learning. They will understand the application of Representation learning to the feature extraction space. They will understand how to apply deep learning techniques for natural language processing. Specifically they will be exposed to the deep learning network architecture used, applicability of deep learning in the field of natural language processing, the algorithm used, how the weights are learnt, lessons learnt and results obtained. The unique contribution of this talk is the methodology of application of deep learning for automatically extracting features from the textual incident management domain data.
