Predictive Analytics using R and Java

Ever wondered how Star Sports is able to show the prediction of cricket match winner? You must have seen some fancy analysis like "India wins the match batting second 80% of the time when Virat Kohli scores 30+ runs in first 10 overs". Recently I delivered a webinar on Predictive Analytics using R and Java on Techgig which has an answer to these questions.

Predictive analytics is about predicting future outcomes based on currently available or historical data using several machine learning algorithms and statistical techniques.

R - a language and environment for statistical computing, makes it really easy to quickly try out several algorithms like Decision Trees, Random Forests, Neural Networks etc. on top of your existing datasets. R packages, like Rattle, can quickly allow you to interactively create machine learning models which can be trained and exported to a PMML file format.

The Predictive Model Markup Language (PMML) is a platform agnostic, XML-based predictive model interchange format which can be used to exchange the trained machine learning models across different technology platforms. Any machine learning model exported in PMML can be imported in your Java program by using libraries like JPPML and can be used to predict future outcomes based on the existing data.

As part of this webinar, you will understand how to quickly create trained machine learning model based on an existing dataset, export it to a PMML file and import into a Java Project.

You will learn about
  1. Basics of Predictive Analytics, brief explanation of Decision Trees, Random Forests and Neural Networks.
  2. How to use R and Rattle to create machine learning models which can be used to predict outcomes based on existing data.
  3. How to train, validate and test machine learning models in R using Rattle.
  4. How to export a trained machine learning model in PMML format using R.
  5. How to use the exported model in PMML format in your Java Program using JPMML

You can find the webinar recording below.

Developing Garmin SmartWatch Apps with ConnectIQ Platform-Part 3

Image
In this third and last part of this tutorial we shall see how to pass the meeting information from the Android app to the SmartWatch app/widget that we developed in part 2 of this tutorial. This part of the tutorial requires some prior knowledge on Android development. If you are in need of a quick android tutorial then you can find it  here . ConnectIQ platform comes with following pre-built mobile SDKs. Android BLE - (actually connects Android app to Smartwatch Apps over BLE) iOS BLE - (connects an iOS mobile app to Smartwatch App over BLE) Android ADB - ( used to simulate BLE connection over ADB) These SDK's  are set of libraries  required to communicate over BLE or to simulate a BLE like connection over ADB (the Android debug bridge). In this part of the tutorial we will look at that Android ADB SDK so that we can simulate the BLE like connection using the emulator in our development environment. You can select and download the Android ADB SDK from the ...

Developing Garmin SmartWatch Apps with ConnectIQ Platform-Part 1

Image
Recently I was involved in developing apps for Gramin Wearables . Being new to the wearables world I found it relatively easier to develop apps for Garmin Wearables then what I had thought earlier. Hence I would like to share my experience via this blog series. I will take you through the step by step process of developing a simple watch widget that synchronizes with an Android phone's Google Calendar to send out meeting alerts and reminders on your Garmin Watch. Apps for Garmin Wearables are developed using the Garmin ConnectIQ SDK   and are programmed using  Monkey C language  . You are already familiar with Monkey C if you are familiar with languages like Java or Objective C. Introduction to  Monkey C language   highlights the basic difference between other languages and Monkey C. Its a short and precise tutorial, I would suggest to give a quick read in case you are planning to develop apps for Garmin. The Problem Statement Lets say you own an And...

Web Service Security and Native Mobile App User Authentication

Image
In this article I am going to throw some light around web service security,  user Authentication  for native mobile applications and how both the topics are connected. Me along with my cool team members at Zycus were working on the same off lately. The idea is to highlight the fact that it is ideal to implement web service security by being agnostic to the type of web service clients (like mobile apps) but these decisions may impact the mobile app user authentication process. If you are working on a mobile application that requires user authentication and fetching data from a server side application then it is highly likely that you are exposing certain functionality of your server side application via web services that can be accessed over the web by your mobile application. While developing such applications you will usually encounter following challenges.  How to secure the web service endpoints?  How to authenticate users from the mobile app in secure way...
