Machine Learning

Activation functions are the one of the important part of the designing neural network. To get better performance from your model you need to have good understanding of these functions. Activation functions are mathematical expression which transform input into certain range of output. You will use activation function in two…

In the most simple words, Linear Regression is the supervised Machine Learning model in which the model finds the best fit linear line between the independent and dependent variable (it finds the linear relationship between the dependent and independent variable). Now don’t get all dizzy I am gonna explain to…

Preface [Disclaimer: I am just getting started in the field. The articles that I write are a way for me to learn more. I write to force myself to dig deep into the topic and get a better understanding. Question everything that I write. I will include references of the resources…

Over the past few years, Data Science has become one of the most in demand jobs that command high salaries in the industry. Taking my own company-Microsoft- and for that matter my own team for example, most Data Scientist have their salaries above $100,000 even with just 1 to 2…

Determinant of Matrix Create square matrix (3 ,3) import numpy as np x=np.matrix(“1,2,3;3,4,5;6,9,4”) print(x) [[1 2 3] [3 4 5] [6 9 4]] syntax :numpy.linalg.det(matrix) det=np.linalg.det(x) print(det) 15.999999999999998 Rank of Matrix The maximum number of its linearly independent rows or ( columns) of a matrix. …

What is Multiple Linear Regression? Multiple Linear Regression or MLR is a type of statistical technique that uses more than one independent variable to predict a dependent variable. This is also a major difference between a simple linear regression and multiple linear regression. It is an extension of simple linear regression. What Multiple linear regression can tell you? Simple linear regression is…

Part 1: How to get in — This is Part 1 in the series. You can find Part 2 here and Part 3 here. At the time of this writing, I have recently finished my PhD in machine learning at ETH Zürich. In retrospect, I have the subjective feeling that I’ve learned a thing or two over…

If the idea of authenticating artwork conjures up the image of people standing around staring at a painting and debating it, you wouldn’t be far from reality. Art historians judge artworks by observing technique and surface details to compare the style of the artist to other known works. Expert opinion…
