When to Categorize Continuous Predictor in a Regression Model?

Research fields usually follow the practice of categorizing continuous predictor variables, and they are the same who mostly use ANOVA. They often do it through median splits, the high value above the median and the low values below the median. However; this it seems is not that good an idea, and enlisted are some of the reasons to it:

  • Median tends to vary from sample to sample. This makes the categories in various samples have various…

Some Computational Photography: Image Quilting (Texture Synthesis) with Dynamic Programming and Texture Transfer in Python

The following problems appeared as a programming assignment in the Computation Photography course (CS445) at UIUC. The description of the problem is taken from the assignment itself. In this assignment, a python implementation of the problems will be described instead of matlab, as expected in the course.

 

The Problems

  • The goal of this assignment is to implement the image quilting algorithm for

    texture synthesis and transfer,…

Will Our Robots Harm Us?

Summary:  We are approaching a time when we need to be concerned that our AI robots may indeed harm us.  The rapid increase in the conversation about what ethics should apply to AI is appropriate but needs to be focused on the real threats, not just the wild imaginings of the popular press.  Here are some data points to help you in thinking about this, what our concerns should be today, and what our concerns should be in the future.

To PhD or not to PhD?

 

...That is the question.

 

Further study often seems the most appealing route to go down, and for many companies out there it’s often heralded as a must have for data science, but it isn’t always so and isn’t always pivotal in advancing your career.

Little Stochastic Geometry Problem: Random Circles

This should remind you of your probability classes during college years. Can you solve this problem in 30 minutes? This could make for an interesting job interview question.

Problem

Points are randomly distributed on the plane, with an average of m points per unit area. A circle of radius R is drawn around each point. What is the proportion of the plane covered by these (possibly overlapping) circles? 

What if circles can have two…

I built a Chatbot in 2 hours and this is what I learned

This article was written by Shival Gupta.

We spend about 5 hours on our smartphones every day as per this study from Flurry. Not only is this statistic surprising in its own right, about 65% of this time is spent on communication related activities like social media, texting, emailing and phone calls. That’s 3 hours and 15 minutes. Every. Single.…

From Artificial Intelligence to Deep Learning

Artificial intelligence or AI for short is the field of making computer think like humans by creating an artificial brain. Whatever the human can do intelligently is required to be moved into machines. The machine will just do what the human tells it and no more. For example, the human can sort numbers in an intelligent manner and so machines should be intelligent by sorting numbers like humans. To do this, there are a number of algorithms like bubble sort that allows the machine to think…

Can Neuroscience unlock the doors to superhuman AI?

Human brain is arguably the most complex material human kind will ever claim to fully understand. The complexity arises somewhat from the fact that there are many (different but compatible to each other) ways of talking about it. One way to talk about it is that it’s made of the same elementary particles as Martian sand dunes and obeys the same physical laws of nature governing violent collision of two massive black holes. Another way to talk about it would be that it’s guilty of two world…

Improving Real-Time Object Detection with YOLO

In recent years, the field of object detection has seen tremendous progress, aided by the advent of deep learning. Object detection is the task of identifying objects in an image and drawing bounding boxes around them, i.e. localizing them. It’s a very important problem in computer vision due its numerous applications from self-driving cars to security and tracking.

Prior approaches of object detection…

Unintended Consequences of the Wrong Measures

In an attempt to put the patient first in healthcare, Congress and President Obama in 2015 approved a bipartisan bill for United States healthcare reform. The bill is known as “Medicare Access and CHIP Reauthorization Act of 2015,” or MACRA. Among the major provisions of MACRA is the Quality Payment Program. Under the Quality Payment Program, physicians and nurses receive positive, neutral or negative Medicare payment adjustments based upon a “Patient Satisfaction Score,” that…
