Build a real-time recommendation engine with IBM Bluemix and PubNub – Part 2

By Shyam Purkayastha | Machine Learning

This post is the follow up to my previous post in which I presented a real-time recommendation engine project around predicting duration of travel. In that post, I explored the factors affecting travel duration and looked at how, with the help of historical data, you can build an algorithm for predicting travel duration for a given route. Now, I will conclude the project by building an application that can help users plan a trip by providing real-time travel recommendations based on current traffic and weather conditions.

In this two-part blog series, I am going to show you how to build a real-time recommendation engine for advising on travel decisions. Travel time or duration is something that is always subject to a lot of speculation. Based on your travel experience along a particular route, you always bet on your intuition to decide when to start your journey. But if you are planning to travel for an all-important meeting to close a deal, a job interview that you have to crack at any cost, or a public event that you have to witness from the very beginning, then you better be prepared and alert, but how?

Smart Traffic Management System for Emergency Services

By Shyam Purkayastha | Internet of Things

When it comes to emergency response, every second counts. For emergency response vehicles, meandering through busy intersections and gridlocked streets can present serious consequences for the person in need of care. In this tutorial, we’ll build a smart traffic management system to address this type of emergency scenario. These types of smart services incorporated into city infrastructure is what truly makes a connected city “connected.”

Three Compelling Use Cases of IoT for Telecom

By Shyam Purkayastha | Telecom

Given all the hype and marketing push around IoT, it is tough to predict how exactly the business models will evolve over the next few years. This is one of the main concerns for industry practitioners. They usually ponder about implementing IoT and end up asking one question, “How can I use IoT in my industry?”. The common approach used to find answers to this question is to look at existing solutions. On one end of the spectrum, we have B2C solutions which are “good to have” ideas but do not solve a real pain. But on the other end, we see a few B2B trends around specific industries where IoT can play a pivotal role. The telecom sector is one such vertical and deploying IoT for telecom opens up a few interesting opportunities.

Smart Highway Toll Collection System

By Shyam Purkayastha | Internet of Things

Vehicles queuing up to pay toll tax at a highway toll gate is a common sight. The toll collection system mostly works on a manual process and can take up to a minute to process each vehicle’s transaction. This has a cumulative effect of increasing traffic congestion, adding delays in travel time and also becoming a pollution hotspot near the toll gate area. Imagine yourself in a car, stuck in one of those long queues. All that you can do is to sit patient till you get past the toll gate.
