Rangasami L. Kashyap  Rangasami Laksminarayan Kashyap (born 28 March 1938) is an Indian applied mathematician and a Professor of Electrical Engineering at Purdue University. He developed (with Harvard professor Yu-Chi Ho) the Ho-Kashyap rule, an important result (algorithm) in pattern recognition. In 1982, he presented the Kashyap information criterion (KIC) to select the best model from a set of mathematical candidate models with different numbers of unknown parameters. These parameters are adjusted to adapt the models to data (observations) that have trends and statistical variation in the measured values. He is a Fellow of the Institute of Electrical and Electronics Engineers, the International Association for Pattern Recognition, and the Indian Institute of Electronic and Telecommunication Engineers. He has also authored translations of all the four Vedas, and also numerous books exploring and discussing the hidden meanings behind the Vedic Mantras of all the four Vedas.
