Arup Kumar Das Email & Phone Number

I am a member of Trust and Safety, and Catalog Data Science teams at Walmart. I contribute across different applications to keep the Walmart catalog safe for customers by detecting offensive items and non-compliant sellers. I, also, work towards improving customer experience by enriching the catalog. I leverage the latest developments in the Data Science space for model development, and scalable infrastructure for model deployment.As an ML researcher at TCS Research, I was engaged in predictive analytics for industrial automation, multi sensor data analysis for machine fault detection, biomedical signal analysis for cognitive studies, and electrical load disaggregation among other works. I have majored in Communication and Signal Processing from IIT Madras. My research work was focused on the design of sync packet and receiver algorithm for reliable communication (probability of incorrect detection tends to zero). Probability, Estimation Theory, Information Theory, Statistical Signal Processing, Digital Signal Processing, and Wireless Communication were the major courses studied at IIT Madras.
