Teaching machines learn the human way !

My research interest lies in developing machine learning and artificial intelligence algorithms inspired by the way human learning works. Towards this end, we use Bayesian learning, deep learning, continual learning, neural networks, stochastic processes, and differential equations to develop novel machine learning and deep learning algorithms. We develop probabilistic machine learning and deep learning models and algorithms for problems from varied domains of artificial intelligence such as computer vision and natural language processing and application areas such as social networks, web, astrophysics, autonomous navigation, smart mobility etc.

Parametric and non-parametric Bayesian models allow the incorporation of prior information and domain knowledge. Non-parametric Bayesian models such as Gaussian processes additionally allow one to learn rich and flexible models due to their non-parametric nature and allow the model complexity to be determined by the data. This helps to overcome the problem of model selection to a great extent. On the other hand, deep learning models help in effective representation learning and good generalisation performance. I work on developing learning algorithms which combines the best from both the worlds for e.g. Bayesian deep learning and deep Gaussian processes. Another line of research is developing continually evolving models based on point process and neural ordinary differential equations. I am also interested in analysing time series and textual data arising from various application domains. Current research applies Bayesian reasoning and probabilistic modelling to diverse problem domains such as computer vision, language processing, social networks, traffic data, astrophysical data etc. We intend to develop learning algorithms and models which are useful not only for artificial intelligence and computer science but also in general for problems arising in other areas of science and engineering.
