The Step(s) Before Predictive Analytics in IoT

leave a comment »

There is no doubt that “Internet of Things” or IoT is the buzz word in technology – destined to change our future forever. And yes I do believe that IoT will change our future or rather the change has begun, and only accelerating. However another buzz word that marries IoT with Big Data – is Predictive Analytics. It is all about how all the sensor and machine data can help find patterns, and be beneficial for use cases like predicting equipment failure. IoT Analytics, I feel, at times is a bubble within a bubble.

Is Predictive Analytics important? Yes it is but not at the cost of how IoT can change the present – not just the future. I see the following steps before you can get into a predictive stage for the mass market (i.e. some use cases probably have crossed several of these steps):

1. Reliable connectivity of sensors, and reliable transfer of data – example did the temperature spike because it actually became hot or it was anomaly because of loose connections or software glitch?

2. If already connected in the world of instrumentation such as SCADA or other legacy proprietary protocols – migrating either the connectivity or the data from the sensors over to the world of IP & Cloud Computing

3. Making present, and the near present better than before: actions that can be taken without the need for predicting the future such as shut down the equipment right now because the temperature has actually spiked.

Predicting the future is one of the many benefits of IoT.

Cancer Sniffing Sensors (& Dogs?)

leave a comment »

Chemistry, Big Data (collecting and matching sample) and Sensors are enabling commercial machines to detect cancers – and detect them accurately. It sounds almost science fiction but is true. Business Week’s Ashlee Vance has written an article on a startup, Metabolomx, and its cancer sniffing machines. 

The Metabolomx machine looks like a desktop PC with a hose attached. It sits on a cart that can be wheeled up to a patient, who is instructed to breathe in and out for about four minutes. The machine analyzes the breath and its volatile organic compounds, or VOCs—aerosolized molecules that, among other things, determine how something smells. Tumors produce their own VOCs, which pass into the bloodstream. The lungs create a bridge between the bloodstream and airways, so the breath exhaled by a patient will carry the VOC signatures of a tumor if one is present. “It may seem surprising, but it’s actually very straightforward,” says Paul Rhodes, the co-founder and chief executive officer at Metabolomx.

I can bet that from a desktop to a much smaller device that then interfaces with a smartphone or better still a Tablet such as the new iPad over Bluetooth LE is not far away. Interesting enough the inspiration originates from the fact that dogs can sniff cancer:

A few years ago researchers in California received widespread attention for showing that dogs can smell cancer on a human’s breath. With 99 percent accuracy the canines could detect if a person had lung or breast cancer, beating the best figures from standard laboratory tests. Subsequent studies confirmed the results and provided further evidence that dogs really are man’s best friend.
