A policy determines the action in a state generating a reward; the goal of reinforcement learning is to learn this policy. RL algorithms have enjoyed a great deal of success in games such as atari, chess or go. https://kirankumar.ai/blog/posts/data_science_process/ Fri, 07 Aug 2020 14:00:00 +0000 https://kirankumar.ai/blog/posts/data_science_process/ Process of Data Science There are various processes which determine success in every field. A surgeon, pilot and scientist undergo many hours of training, spanning years, to practice. The hours of training are generally used to establish skills towards automaticity. The development of automaticity enables quick decisions and efficient management of tough situations. This idea of automaticity is enshrined in many theories of cognitive science such as the two process model by Schneider and Shiffrin in 1977. https://kirankumar.ai/blog/posts/data_science_measurement/ Fri, 07 Aug 2020 14:00:00 +0000 https://kirankumar.ai/blog/posts/data_science_measurement/ Measurement variables In a previous post, the process of data science and forming an hypothesis is discussed. A hypothesis is the relevant to align a business objective to a data science problem. The hypothesis provides a “big-picture” view of the issues which need to considered in further steps of addressing a data science problem. https://kirankumar.ai/blog/posts/attention/ Sun, 13 Jan 2019 22:27:46 +0000 https://kirankumar.ai/blog/posts/attention/ The digital era and the digital economy are driven by industrial disruptions such as Amazon - e-commerce, Facebook — social interaction, Netflix — entertainment, Uber — transportation and many such ventures. The key aspects of a digital economy are scale and speed. Scale conveys these digital ventures capture a user base of millions (if not billions). Speed conveys their ability to grow and adapt to the market at a rapid scale.
