Bats in the machine

Scene from the immortal serial "The Batmen of Africa.

A lot of the chatter about machine learning is ‘bright shiny thing’ chatter. Like Tim the Tool Man with a SnapOn Tools catalog, the proponents rush ahead of the reality, painting pictures of distributed server farms iterating blissfully. Aside from the low hanging fruit of the recommendation engine, what applications are there?

An October 2015 issue of the IEEE Spectrum (always a favorite publication) takes the time to look at machine learning from an applications point of view. And a practical application at that. No, its not about reaping in big profit. It is about doing science. And trying to improve on governments' response to Ebola, which in its last outbreak took more than 11,000 lives.

Researcher Barbara Han tells about her use of machine learning algorithms to try and predict which reservoir species- bats or others- could come to harbor a disease like Elbola. Let’s not sit around and wait for the next epidemic, she suggests, let’s instead use computer power to try and foresee the path ahead.

Han said she and her Cary Institute of Ecology colleagues used machine learning to go through vast mounds of unstructured data about wildlife - trying to identify the traits that might alert us to possible ebola-disease-type sources. Along the way she provides a pretty succinct description of the machine learning processs. In machine learning the steps are:

1. Obtain training data set
2. create an initial classification tree
3. split the data set into two groups using randomly selected features - in this case for example, body size, which for the little varmints she is parsing could be ‘under or over’ 1KG
4. Use algorithm to build a second tree that prioritizes misclassified species in the attempt to sort them correctly
5. Repeat. Iteratively. Generate thousands of trees. See the classification accuracy improve.
6. When you get the model performing well on training data, then you
7. Make predictions, using the rest of the data set.


The interesting thing is that you're not waiting for the outbreak to react. Your machine does not get bored with the rote tasks. With ecological systems that have many many variables this is especially useful. I wonder of course if we arent ultimately driven by catastrophe.(batastrophe?)  We have a lot of data on those African bats - the researchers have gathered 30,000 individuals from hundreds of thousands of samples. Of course, The Cary group's  work of prediction, which guesses at likely newcomer carriers, would at least give a leg up. Han says they can suggest areas 'where to look for trouble'' - a model that looked at 58 rodent species could become culprits, they say. And a possible trouble spot could be in the Great Plains of the U.S., spanning from Nebraska south to Kansas. - Jack Vaughan

Escape from the glass house - thoughts on Gates and VB

Sometimes, this blog will venture into the deep past... In 2006, the news that Bill Gates was about to retire made me think. His move to give away money to good causes and to gradually remove the heavy yoke of incredibly unbelievable wealth, had given pause to some of us. Gates was championed by many, and criticized by many too. My long-time colleague, Rich Seeley drolly summed it: "This may be like when Ali left boxing; software may never be as fun without Gates to kick around." At the time, I wrote: I'd been in the hardware trade press for 10 years when my boss assigned me to cover a Microsoft product rollout in Atlanta. Call it a simple twist of fate. It was 1991. Of course I'd heard of Bill Gates, but he was in the software business, and of just about no interest to us. If he'd been doing assembler, of course, that would have been of a whole lot of interest, but he was doing Basic, which "real men" didn't do, back in those hardware circles. But the company was on the rise, and the boss sent me. The product rolling out, in fact, was Visual Basic, which has just lately turned 15. There was tension in the air at the launch as we waited for the keynote speaker. Then, Bill Gates came out and just about everybody stood up and cheered clamorously. In those days hardware trade journalists didn't applaud (politely or otherwise) at the end of an industry executive's speech, much less stand up when they just appeared on stage. So I covered the story of the birth of Visual Basic, and had one eye on the rapt audience as I did so. Later on I caught on to the fact that Bill Gates had become the richest man in the world and people were fascinated by that mere fact. Of course, there was real excitement about Visual Basic and Microsoft because the software was enabling for people who grew up during the batch processing era, when gatekeepers in smocks stood between you and the problem you wanted to crunch on.
