Companies that deploy machine learning will have a significant competitive advantage. The possibility to identify trends, demands and markets ahead of the curve will play a large part in reshaping the way companies display content to users. Not only will machines be able to identify, predict, and help us understand users, they’ll also be able to adjust price models and improve content and product recommendations accordingly. Dipesh Yadav was one of the first developers to join FROSMO and currently holds the position of Senior Full-Stack Web Developer. He attended FrosmoX16 as a guest speaker.
