ADaBoost.M1 tries to improve step by step the accuracy of the classifier analyzing its behavior on training set. (Of course you cannot try to improve the classifier working with the test set!!).

In this scenario, try to improve the accuracy of classifier assigning different weights…

There was a long article today in the Seattle Times about how terrible Washington State is - according to Brad Smith - in terms of educating its citizens.…Continue

It's interesting when I read dismissive blogs about 'Point in Time' data suggesting it's no longer relevant. I would like to introduce one fundamental data type that does not change and directly impacts business performance: talent analytics. These are numbers representing stable characteristics about how we work naturally and what we are driven by. Think of them as your strengths in numbers form.
Since we all have people in our lives, I don't need to post 10 links…Continue

Point in Time (PiT) v Through the Cycle (TTC)
There used to be an argument about this; its clear to me now that this is more than an arithmetic conundrum about Ratings and RWAs its a philosophical matter applicable to wider aspects of life & thus any arguments for PiT are just lazy and myopic. Here are some good recent references; I have selected recent papers since the debate has evolved towards a conclusion since it first developed 2 or so years ago. The game has…Continue

Economic pressure drives businesses to find every advantage for increased business performance. While enterprises have carefully chosen key performance indicators, they are housed separately from key performance indicators of the people who do the work, missing an opportunity to quantitatively link a company's talent characteristics to business operations and outcomes.
IIA's January Office Hours call will discuss the connections between innate talent characteristics and enterprise…Continue

My company (Discovery Corps, Inc.) president Tim Graettinger has released a new article I think you'll like:
"If you’re a data miner, there’s a good chance you saw the movie Moneyball. For me, the movie was entertaining, but the book was really enlightening. I found it to be a source of numerous and familiar lessons about data mining - while couched in the intriguing context of major league baseball. In this article, I’d like to share some of…
