R Decision Trees - A Tutorial to Tree Based Modeling in R

What is R Decision Trees?

One of the most intuitive and popular methods of data mining that provides explicit rules for classification and copes well with heterogeneous data, missing data, and nonlinear effects is decision tree. It predicts the target value of an item by mapping observations about the item.

You can perform either classification or regression tasks here. For example, identifying fraudulent…

R Nonlinear Regression Analysis

R Nonlinear Regression Analysis

Nonlinear Regression and Generalized Linear Models:

Regression is nonlinear when at least one of its parameters appears nonlinearly. It commonly sorts and analyzes data of various industries like retail and banking sectors. It also helps to draw conclusions and predict future trends on the basis of user’s activities on the net.

The nonlinear regression analysis is the process of building a…

How to Spot Visualization Lies

This article was written by Nathan Yau.

It used to be that we’d see a poorly made graph or a data design goof, laugh it up a bit, and then carry on. At some point though — during this past year especially — it grew more difficult to distinguish a visualization…

Under the Hood with Reinforcement Learning – Understanding Basic RL Models

Summary:  Reinforcement Learning (RL) is likely to be the next big push in artificial intelligence.  It’s the core technique for robotics, smart IoT, game play, and many other emerging areas.  But the concept of modeling in RL is very different from our statistical techniques and deep learning.  In this two part series we’ll take a look at the basics of RL models, how they’re built and used.  In the next part, we’ll address some of the complexities that make development a…

Time series classification with Tensorflow

Time-series data arise in many fields including finance, signal processing, speech recognition and medicine. A standard approach to time-series problems usually requires manual engineering of features which can then be fed into a machine learning algorithm. Engineering of features generally requires some  domain knowledge of the discipline where the data has originated from. For example, if one is dealing with signals (i.e. classification of EEG signals), then possible features would involve…

IoT: Penetrating the Possibilities of a Data Driven Economy

All of us are accustomed to the smart wearables, such as the ones we wear on a jogging track. We also have seen the concept of smart homes turn into a reality. We have seen a farmer sort and track his flock of sheep with the help of a mountable RFID device. 

Every physical element around us (including ourselves) have become a part…

Predicting the next Eclipse

Here we describe a rudimentary method, using basic trigonometry, to predict lunar and solar eclipses. The purpose is to get people interested in the mathematics behind these events. We assume here that the Sun, the Earth and the Moon are just points. Thus we do not predict where on Earth eclipses take place, nor whether they are full of partial. But we derive some interesting results, such as

  • Solar eclipses are as frequent as lunar eclipses
  • On average, a solar eclipse…

Quick Guide to R and Statistical Programming

Guest blog by Rob Kabacoff. Rob is Professor of Quantitative Analytics at Wesleyan University.

R is an elegant and comprehensive statistical and graphical programming language. Unfortunately, it can also have a steep learning curve. I created this website for both current R users, and experienced users of other statistical packages (e.g., SASSPSSStata) who…
