Unsupervised Machine Learning, Most Promising Ingredient Of Big Data

Orange (France Telecom), one of the largest mobile operators in the world, issued a challenge "Data for Development" by releasing a dataset of their subscribers in Ivory Coast. The dataset contained 2.5 billion records, calls and text messages exchanged between 5 million anonymous users in Ivory Coast, Africa. Various researchers got access to this dataset and submitted their proposals on how this data can be used for development purposes in Ivory Coast. It would be an understatement to say these proposals and projects were mind-blowing. I have never seen so many different ways of looking at the same data to accomplish so many different things. Here's a book [very large pdf] that contains all the proposals. My personal favorite is AllAborad where IBM researchers used the cell-phone data to redraw optimal bus routes. The researchers have used several algorithms including supervised and unsupervised machine learning to analyze the dataset resulting in a variety of scenarios.

In my conversations and work with the CIOs and LOB executives the breakthrough scenarios always come from a problem that they didn't even know existed or could be solved. For example, the point-of-sale data that you use for your out-of-stock analysis could give you new hyper segments using clustering algorithms such as k-means that you didn't even know existed and also could help you build a recommendation system using collaborative filtering. The data that you use to manage your fleet could help you identify outliers or unproductive routes using SOM (self organizing maps) with dimensionality reduction. Smart meter data that you use for billing could help you identify outliers and prevent thefts using a variety of ART (Adoptive Resonance Theory) algorithms. I see endless scenarios based on a variety of unsupervised machine learning algorithms similar to using cell phone data to redraw optimal bus routes.

Supervised and semi-supervised machine learning algorithms are also equally useful and I see them complement unsupervised machine learning in many cases. For example, in retail, you could start with a k-means to unearth new shopping behavior and end up with Bayesian regression followed by exponential smoothing to predict future behavior based on targeted campaigns to further monetize this newly discovered shopping behavior. However, unsupervised machine learning algorithms are by far the best that I have seen—to unearth breakthrough scenarios—due to its very nature of not requiring you to know a lot of details upfront regarding the data (labels) to be analyzed. In most cases you don't even know what questions you could ask.

Traditionally, BI has been built on pillars of highly structured data that has well-understood semantics. This legacy has made most enterprise people operate on a narrow mindset, which is: I know the exact problem that I want to solve and I know the exact question that I want to ask, and, Big Data is going to make all this possible and even faster. This is the biggest challenge that I see in embracing and realizing the full potential of Big Data. With Big Data there's an opportunity to ask a question that you never thought or imagined you could ask. Unsupervised machine learning is the most promising ingredient of Big Data.

15 YEARS OLD GIRL IMPREGNATED AND MAN RESPONSIBLE FOR IT TOOK FOR AN ABORTION THAT FAILED

BBI FACILITATE ARREST OF 35 YEARS OLD FOR DEFILEMENT, IMPREGNATING 15 YEARS OLD GIRL AND ABORTING FIVE MONTHS PREGNANCY IN ANAMBRA STATE. Today, at 1:26pm, We received a complaint from a concerned citizen who informed us of a 15yrs old girl brought into a hospital for medical treatment. Our intelligence team led by Director General Gwamnishu Emefiena Harrison Kenneth Nwaobi Ezika Kene and others left Asaba and arrived Ogidi Anambra state for investigation. 35yrs Chris Azuoma took the victim to hospital where she was injected and given abortion pills. She bled heavily and had complications and so decided to take her to a specialist hospital to evacuate the foetus. Getting to the hospital, we met the management and identified ourselves as Human rights group and they granted us permission to interview the victim. She confirmed the story and the perpetrator confessed forcefully having unprotected sexual intercourse with the victim. 2015 Administration of Criminal Justice permit private per

Hacking Into The Indian Education System Reveals Score Tampering

Debarghya Das has a fascinating story on how he managed to bypass a silly web security layer to get access to the results of 150,000 ISCE (10th grade) and 65,000 ISC (12th grade) students in India. While lack of security and total ignorance to safeguard sensitive information is an interesting topic what is more fascinating about this episode is the analysis of the results that unearthed score tampering. The school boards changed the scores of the students to give them "grace" points to bump them up to the passing level. The boards also seem to have tampered some other scores but the motive for that tampering remains unclear (at least to me). I would encourage you to read the entire analysis and the comments , but a tl;dr version is: 32, 33 and 34 were visibly absent. This chain of 3 consecutive numbers is the longest chain of absent numbers. Coincidentally, 35 happens to be the pass mark. Here's a complete list of unattained marks - 36, 37, 39, 41, 43, 45, 47, 49, 51, 53,

Reveiw: Celluon Epic Laser Keyboard

The Celluon Epic is a Bluetooth laser keyboard. The compact device projects a QWERTY keyboard onto most flat surfaces. (Glass tabletops being the exception) You can connect the Epic to vertically any device that supports Bluetooth keyboards including devices running iOS , Android , Windows Phone, and Blackberry 10. On the back of the device there is a charging port and pairing button. Once you have the Epic paired with your device it acts the same as any other keyboard. For any keyboard the most important consideration is the typing experience that it provides. The virtual keyboard brightness is adjustable and is easy to see in most lighting conditions. Unfortunately the brightness does not automatically adjust based on ambient light. With each keystroke a beeping sound is played which can be turned down. The typing experience on the Epic is mediocre at best. Inadvertently activating the wrong key can make typing frustrating and tiring. Even if you are a touch typist you'll still
