Probability, Paradox, and the Reasonable Person Principle
|
Peter Norvig
from October 03, 2015
In this notebook, we cover the basics of probability theory, and show how to implement the theory in Python. (You should have a little background in probability and Python.) Then we show how to solve some particularly perplexing paradoxical probability problems.

Refined Math Model May Provide Insights on Mutations Leading to Cancer
|
GEN News Highlights
from October 01, 2015
Scientists at Virginia refined a mathematical model that simulates the impact of genetic mutations on cell division, a step that could provide insight into errors that produce and sustain harmful cells, such as those found in tumors. In a study (“Experimental testing of a new integrated model of the budding yeast START transition”) in Molecular Biology of the Cell, the group detailed their findings in laboratory experiments, which examined how mutant cells moved through a series of processes to duplicate their genetic material and divide.
Using these results, the team says it developed more accurate techniques for predicting the effects that gene mutations will have on a cell’s ability to regulate its rate of division using natural checkpoints such as cell size and the availability of nutrients.

VW’s Fraud Reveals A Troubling Future: Our Machines Can Now Lie | Co.Design | business + design
|
Fast Company, Co. Design
from October 01, 2015
Volkswagen didn’t make a faulty car: They programmed it to cheat intelligently. The difference isn’t semantics, it’s game-theoretical (and it borders on applied demonology).

How Spotify’s Discover Weekly cracked human curation at internet scale | The Verge
|
The Verge
from September 30, 2015
… Spotify has found a new way to tap the collective intelligence of its 75 million users, turning their taste into a data layer that can be used to better personalize everyone’s experience. I’m not the only one who noticed. “It’s good. It’s better than I thought it would be,” says tech entrepreneur and web pioneer Anil Dash. To Dash, Discover Weekly felt carefully tended, even though it was being produced by machines. “They’re as good as DJs — at scale.”
“At first I was a bit skeptical,” says Billy Chasen, founder of Turntable.fm. “I was definitely in the camp that believes you really need people to help find music for you, [that] algorithms can only take you so far.” After a few weeks using Discover, Chasen was a believer. “One [song] every week is a real gem. All of a sudden it’s like, this thing is awesome.”

Hurricane Joaquin Forecast: Why U.S. Weather Model Has Fallen Behind – The New York Times

The New York Times, TheUpshot blog
from October 03, 2015
If this forecast holds, Hurricane Joaquin will yield one clear winner: the model from the European Center for Medium-Range Weather Forecasts — or simply, the European model — which consistently forecast that Joaquin would head off to sea.

More-flexible machine learning | MIT News

MIT News
from October 01, 2015
Machine learning, which is the basis for most commercial artificial-intelligence systems, is intrinsically probabilistic. An object-recognition algorithm asked to classify a particular image, for instance, might conclude that it has a 60 percent chance of depicting a dog, but a 30 percent chance of depicting a cat.
At the Annual Conference on Neural Information Processing Systems in December, MIT researchers will present a new way of doing machine learning that enables semantically related concepts to reinforce each other.

Syllabus for my course on Communicating Data and Statistics – Statistical Modeling, Causal Inference, and Social Science
|
Andrew Gelman
from October 02, 2015
Actually the course is called Statistical Communication and Graphics, but I was griping about how few students were taking the class, and someone suggested the title Communicating Data and Statistics as being a bit more appealing. So I’ll go with that for now.
I love love love this class and everything that’s come from it (including statistics diaries and ShinyStan).

I’m Hadley Wickham, Chief Scientist at RStudio and creator of lots of R packages (incl. ggplot2, dplyr, and devtools). I love R, data analysis/science, visualisation: ask me anything!

from September 29, 2015
Broadly, I’m interested in the process of data analysis/science and how to make it easier, faster, and more fun. That’s what has lead to the development of my most popular packages like ggplot2, dplyr, tidyr, stringr. This year, I’ve been particularly interested in making it as easy as possible to get data into R. That’s lead to my work on the DBI, haven, readr, readxl, and httr packages. Please feel free to ask me anything about the craft of data science.
I’m also broadly interested in the craft of programming, and the design of programming languages. I’m interested in helping people see the beauty at the heart of R and learn to master it as easily as possible.
