Krishnendu Chaudhury

Krishnendu Chaudhury is an American Technology leader (deep learning, computer vision), inventor, and author.[1][2] He is the co-founder of Drishti Technologies in Palo Alto, CA. Currently, he is serving as the Chief Technology officer (CTO) of the company. Chaudhury is also the author of the book Mathematics and Architectures of Deep Learning. He has 34 patents [3] to his name and several publications in the field of computer vision and deep learning.[4] Over the course of his career, he has worked at Adobe Systems, Google, and Flipkart.[1][2]

Early life and education

In 1994, he completed his Ph.D. in computer science in computer vision and image processing from the University of Kentucky.[5]

Career

In 1995, Chaudhury started working for Adobe Systems as a senior computer scientist. He worked with Adobe for ten years working on Advanced Technology Group and Postscript Core Technology, working in different locations, including San Francisco and San Jose.[1][2]

In 2005, he joined Google.[1][2] He worked on image processing and computer vision projects. He worked on several projects that revolved around machine learning and computer vision, including Google's newspaper search feature, which was launched in 2008 on Google's 10th birthday. The product allows readers to go through newspaper archives from hundreds of newspapers and thousands of issues from the 1800s and early 1900s.[6] Chaudhury also managed Google's version of image compression called "WebP," which was launched in October 2010. He worked on the auto-rectification of photos at Google Photos, devising a complex mathematical way to restore parallelism of lines inside an image. He also worked on an early version of a face recognition-based login for Android.[7] After 10 years of service, he left Google and joined Flipkart.

In 2015, Chaudhury joined Flipkart as a Principal Scientist and Head of Image Sciences, handling projects related to computer vision and deep learning.[8] He worked on deep learning in the e-commerce visual search and recommendation systems. Chaudhury led the computer vision and image processing technology team across Flipkart's platforms.[8] His team led the first visual recommendation engine, which would recommend visually similar products. His notable works for Flipkart include Deep Learning based Visually Similar recommendations for Flipkart: A new Convolutional Neural Net (CNN) architecture for visual feature embeddings,[9] and Region CNN-based e-commerce product localization on wild images: Identifying Flipkart apparel similar to the ones worn by models/celebrities/friends in wild images.[10]

In 2017, he co-founded Drishti Technologies in Palo Alto, CA, with Prasad Akella and serial entrepreneur Ashish Gupta.[1] Drishti Technologies works on AI-powered video analytics and video traceability.[11] Drishti is a Silicon Valley AI startup funded by VCs including Andreessen Horowitz, Emergence Capital, and Benhamou Global Ventures.[12] Chaudhury is also on the Technical Advisory Committee of Benhamou Global Ventures since 2017. He holds the position of CTO at Drishti Technologies, working on Applying Deep Learning and Computer Vision.[2]
