Knowledge is skill in action.

Learning is an evolution.

Premjith B

I am a PhD student at Center for Computational Engineering and Networking at Amrita Vishwa Vidyapeetham, Coimbatore, India under the supervision of Dr. K.P Soman. My current research focus is on Natural Language Processing (NLP) and Deep learning. I am interested in applying deep learning techniques in the computational processing of Indian languages. My dissertation is on Neural Machine Translation from English to Malayalam and building deep learning based NLP tools for Malayalam. Apart from Malayalam, I also developed deep learning based NLP tools for various Indian languages. I also worked on applying kernel methods and explicit feature mapping algorithms in predicting network anomalies. Now, I am learning the math of Reinforcement Learning and Dynamic Mode Decomposition (DMD).


My research focuses on Natural Language Processing - in particular, I am working on the development of NLP tools for linguistically rich Indian languages using deep learning algorithms. These tools can be effectively utilized in Neural Machine Translation, Indian language spoken dialogue system, Robotics, social media text analytics etc. Along with the machine learning/deep learning tools, I also prepared data-sets for different NLP tasks such as Machine Translation, Morphological analysis, Sandhi splitting, Parts-of-Speech tagging and Named Entity Recognition in Indian languages.

Goal of my research is to take the common man to the world of flooded knowledge and let them learn through their spoken language or mother tongue.

Some topics of interests are:

  • Neural Machine Translation
  • Incorporating Artificial Intelligence to learn the grammatical rules of natural languages.
  • Models of linguistically rich languages such as Sanskrit, Malayalam, Tamil, Hindi, Telugu and also for Arabic
    • Morphological analyser
    • Sandhi splitter
    • Named Entity Recognition (NER) tagger
    • Parts of Speech (POS) tagger
    • Word Sense Disambiguation (WSD)
  • Social media text analytics
  • Biomedical text mining
  • Kernel methods and explicit random feature mapping algorithms
  • Network anomaly detection
  • Deep learning - in particular, Recurrent Neural Network and Long Short-Term Memory Networks
  • Reinforcement Learning
  • Probability and Graphical Models
