This talk is about - why AI/ML is so important today and how to follow an approach of doing Supervised Machine Learning algorithms from prototype to production - how to choose and transform the data, how to choose the model/algorithm and evaluate it so you have the best results in the future.
45. • Instead of using two coordinates ( 𝒙, 𝒚) to describe
point locaCons, let’s use only one coordinate (𝒛)
• Point’s posiCon is its locaCon along vector 𝒗↓ 𝟏
