Not Too Deep CNN for Face Detection in Real Life Scenario
Sanjoy Chowdhury, Parthasarathi Mukherjee, Ujjwal Bhattacharya
International Conference on Next Generation Computing Technologies, Springer, 2017 (Best paper award, Oral)
Paper /
Code
Proposed a multi-scale face detection framework that is capable of detecting faces of multiple size and different orientations in low resolution images while achieving sufficiently low latency and modest detection rates in the wild.

Classification of Citation in Scientific Articles
Sanjoy Chowdhury, Harsh Vardhan, Pabitra Mitra, Dinabandhu Bhandari
National Conference on Recent Advances in Science and Technology, 2016 (Oral)
Abstract /
Code
Designed a multi-class classification system to find out the type of citation i.e. a citation belongs to which facet. We aimed to
achieve this by extracting and analysing citation information from the text.
