I've had a great time using DC.js - highly recommended... It's a wrapper around both D3.js and crossfilter.js and makes building linked interactive charts / dashboards really easy.

I really don't like the arrogance coming through the writing style, especially given how clear it is the author has at best basic working knowledge of ML. Never mind the fact that k-means is ML 101 and the $500M company is likely using

I think this may have something to do with Jeremy Howard's time as president there - I remember watching a few of his tutorials a couple of years ago when he was still at Kaggle and he was really into C#.

I spoke to some Uber drivers in Johannesburg (also insane murder rate) and they said the same thing - things got dangerous when they started having to carry cash. Worst thing is they were sold on becoming Uber drivers with the promise that

I threw all of the above plus CNNs at MNIST problem and boosted decision trees outperformed CNNs. Granted if I tuned both perfectly, CNNs probably would have outperformed but with defaults and a small amount of parameter search, boosting wo

There was a great talk by some AWS guys at the aws re-invent summit on ways to improve accuracy using ideas similar to cross-validation... It's on iTunes - title is: "Getting to ground truth with Amazon web services mechanical Tur

My back and shoulders have been hurting more and more (I'm only 27!) and it took me way too long to accept that slouching over my laptop was causing it. Putting my laptop on a pile of books and using an external keyboard and mouse made

Check out d3.js - building a GIS app myself on top of d3 and it's really powerful and runs in the browser. Will have to do the GIS calcs server side and just use d3 to render but that plays really well with PostGIS...

You should start with "Introduction to Statistical Learning" which is the baby brother of "Elements of Statistics Learning" (arguably THE reference book) - it's easy to follow and has examples in R, a functional lan

Super easy to call R scripts from python - can use rpy2 to send dataframes from R to pandas or can just run an R script that outputs a csv to a folder and then read that in python... Legit 3 lines import rpy2.robjects as robjects #

Kinda hacky but I believe if you tinker with the accumulator cutoff parameter, you can detect circular arcs just using the Hough circle transform but I think it'd be specific to the problem and being able to tune the cutoff parameter r

Very concise explanation! Posted this before - had to implement Hough circle detection from scratch in JavaScript in case anyone is interested: https://github.com/alexanderconway/Hough-Circle-Detection

You can create a candidate list of titles for those books that do get linked then check for those titles in the body of each comment - not too computationally expensive and embarrassingly parallel.

The counter argument is that social media being designed to distract you makes it good training for your concentration. You don't need to avoid grocery stores that sell chocolate to stop getting fat, just get more disciplined.

I think it's totally misleading to say that the 100M photos are "available for all" and described as an "open repository of photos" when there is no simple way to download the full database of photos. I understand t
