Image Processing and Neural Networks Intuition: Part 1

In this series, I will talk about training a simple neural network on image data. To give a brief overview, neural networks is a kind of supervised learning. By this I mean, the model needs to train on historical data to understand the relationship between input variables and target variables. Once trained, the model can be used to predict target variable on new input data. In the previous posts, we have written about linear, lasso and ridge regression. All those methods come under…

Machine Learning Explained: Understanding Supervised, Unsupervised, and Reinforcement Learning

Once we start delving into the concepts behind Artificial Intelligence (AI) and Machine Learning  (ML), we come across copious amounts of jargon related to this field of study. Understanding this jargon and how it can have an impact on the study related to ML goes a long way in comprehending the study that has been conducted by researchers and data scientists to get AI to the state it now is. 

In this article, I will be providing you with a comprehensive definition of supervised,…

Who will get hired at Google?

In this script, we will explore the open roles at Google, and try to see what common attributes Google is looking for, in future employees. 

This dataset contains text information about job location, title, department, minimum and preferred qualifications and the responsibilities of the position. Using this dataset we will try to answer the following questions:

  1. Where are the open roles?
  2. What are the minimum and preferred educational qualifications needed…

Relational Algebra Is the Root of SQL Problems

There is no doubt that SQL is the most widely-used working language for processing structured data. Not only is the language adopted by all relational database products, but its implementation is the goal of many newly-invented big data platforms. But in many aspects SQL isn’t so convenient to use in handling various computational and query demands. The procedurality issue stated in the last article is just a superficial one. SQL’s problems are rooted in its theory foundation, the relational…

7 Visualizations You Should Learn in R

This article was posted by Dikesh Jariwala on R Bloggers.

With ever increasing volume of data, it is impossible to tell stories without visualizations. Data visualization is an art of how to turn numbers into useful knowledge.

R Programming lets you learn this art by offering a set of inbuilt functions and libraries to build visualizations and present data. Before the…

Machine Learning Guide and Tutorial for Software Engineers

This article was written by Nam Vu on GitHub. 

What is it? 

This is my multi-month study plan for going from mobile developer (self-taught, no CS degree) to machine learning engineer.My main goal was to find an approach to studying Machine Learning that is mainly hands-on and abstracts most of the Math for the beginner. This approach is unconventional because it’s the top-down and results-first approach designed for…

Number Theory: Nice Generalization of the Waring Conjecture

The Waring conjecture - actually a problem associated with a number of conjectures, many now being solved - is one of the most fascinating mathematical problems. This article covers new aspects of this problem, with a generalization and new conjectures, some with a tentative solution, and a new framework to tackle the problem. Yet it is written in simple English and accessible to the layman.

I also review a number of famous related mathematical conjectures, including one with a $1…

Design Patterns for Deep Learning Architectures - with Free eBook

This article comes from DeepLearningPatterns.. 

Deep Learning can be described as a new machine learning toolkit that has a high likelihood to lead to more advanced forms of artificial intelligence. The evidence for this is in the sheer number of breakthroughs that had occurred since the beginning of this decade. There is a new found optimism in the air and we are now again in a new AI spring.

Unfortunately, the current state of deep learning appears to many ways to be…
