In a previous post on Numerai, I have described very basic code to get into a world of machine learning competitions. This one will be a continuation, so if you haven’t read it I recommend to do it- here. In this post, we will add little more complexity to the whole process. We will split out 20% of training data as validation set so we…

In this post, I want to share, how simple it is to start competing in machine learning tournaments – Numerai. I will go step by step, line by line explaining what is doing what and why it is required. Numerai is a global artificial intelligence competition to predict financial markets. Numerai is a little bit similar to Kaggle but with clean datasets, so we can…

What is Neural Network? Definition Artificial Neural network is a system of individual processing units (Neurons) connected usually in a structured manner. It is designed to mimic operation and model the way human brain solves problems. Each individual neural unit has a function which processes the values of all its inputs. The organization and weights of connections determine the output of the model. Neural networks are adaptive,…

What is a definition of Machine Learning? Machine Learning subfield of science that provides computers with the ability to learn without being explicitly programmed.   The goal of Machine Learning is to develop learning algorithms that do the learning automatically without human intervention or assistance, just by being exposed to new data. The Machine Learning paradigm can be viewed as “programming by example”. This subarea of…

There is much debate on it, but the short definition of data science is: “Data science is an interdisciplinary field of using scientific methods to get information from data in various forms.” Data science involves using methods from fields of statistics, computer science, and mathematics, to interpret data for business decisions. Amounts of data available in modern society grow with the input of technology in people’s lives….
