COLOSSUS is a national level IT fest conducted by GSS BCA. We are into the 4th version of the fest code named DENNIS . This fest aims to congregate the best of young minds to get them put on their thinking caps, explore and materialize their ideas. The theme of COLOSSUS- DENNIS is ” Machine learning”. Machine learning gives computers the ability to learn and adapt through experience, without being explicitly programmed. We probably use it dozens of times a day without knowing. Machine learning has given us self-driving cars, practical speech recognition, online recommendation offers, effective web search, and a vastly improved understanding of the human genome. Machine Learning is the big frontier in big data innovation. The process of machine learning begins with observations or data, direct experience, or instruction in order to look for patterns in data.
