I want to learn statistics and data mining | johnmyleswhite: If your math background is weak enough that you don't feel totally at home using calculus and linear algebra, I'd recommend "Principles of Data Mining", which they use for the intro to ML class at Princeton.

I want to learn statistics and data mining | eob: Thanks for these links everyone |
I want to learn statistics and data mining | owinebarger: I'll make a non-mathematical observation about data-mining. Real world data sets are messy.

You have to validate/scrub/realign your data set before wasting time on an anal... |

What APIs do you wish existed? | rwhitman: A solid global small business geo data API.Fortunately there are a few different startups working on this, and a rudimentary way to hack it with Google AJAX API but there's still nobody who can allow me to simply punch in name+city search and give me the address, geocode meta reliably for any city in the worl... |

I want to learn statistics and data mining | HilbertSpace: Early in my career, I asked that question. Eventually I got some answers.Broadly usually the 'big bucks' are in things that are new at least in some important sense.

Has anyone used machine learning to trade? | cperciva: Is it a complete waste of time to try without being a big fish (I've only got about 10K to venture on this)?Yes.

Has anyone used machine learning to trade? | wclax04: If you're interested in this, why not join a firm that does it? They will have a large capital base to start with and eventually start your own venture. Unfortunately 10k won't get you very far in this game |
Has anyone used machine learning to trade? | ct: Being a "small fish" is actually an advantage since you have less capital you need to put to work and thus can more easily get fills and catch the bigger waves generated by the bigger fish institutions like mutual and hedge funds.The institutions have to hold on for longer periods and can't really "scalp" trades pe... |
Has anyone used machine learning to trade? | patio11: A strange game. The only way to win is not to play. |
Has anyone used machine learning to trade? | Create: intraday NN is irrelevant because NN are prone to overlearning, so the stuff becomes even more horrible - actually in reality you don't care which way it moves, as long as it moves: this is why the "big fish". It is like owning the place in Vegas: you don't care about the bets (much less about their substance o... |
Has anyone used machine learning to trade? | dpapathanasiou: I have friends who do this, and they told me, anecdotally, that for every 10 trades they do, 8 or 9 lose money.While they do make it up on the rest, you have to ask yourself if you can afford the costs (brokerage commissions and fees) of executing your strategy in that context (they all work for banks a... |

I would love to hear about anyone else who is ... |
Please review my automated web testing startup, Browsera | bluebird: This seems like a very useful service. I think that you may be losing quite a lot of business by jumping from free to $49 directly.There is probably a sweet spot at around $19 for say 250 pages and login support that would attract a lot of hobbyists/developers who work on one web app or a couple of sites and ... |
What APIs do you wish existed? | xinsight: iTunes Connect (Contains sales, payments, reviews, ratings for publishers with products in iTunes) |
Getting started with geospatial data? | RiderOfGiraffes: Close enough is good enough.Given a (lat,lng) of (A,B) and another of (X,Y), each in degrees, the distance between them is (roughly) sqrt( (A-X)^2 + (B-Y)^2 )
in degrees, and to convert to miles you use 360 degrees is 25000 miles.OK, now that's not quite right, because as your latitude increases the ... |
Has anyone used machine learning to trade? | copernicus: In general, machine learning would probably not be a great approach to day trading. There are several problems:1) Limited market data: As an individual, you have limited access to market data.

Has anyone used machine learning to trade? | randomtask: I don't know much about stock markets, but I did a consulting gig for a large currency trading company a while back where I was doing a bit of work on their algorithmic trading platform.

Has anyone used machine learning to trade? | ctkrohn: If you're interested in reading more, take a look at the message board http://www.nuclearphynance.com.And $10K will almost certainly not be enough. You'll spend all your money paying commissions or bid/ask. |
Has anyone used machine learning to trade? | schemer: 10K is too little. Statistically speaking, a small draw down can wipe out your acount.

If you are really interested in m... |
Has anyone used machine learning to trade? | keefe: My understanding is this is a pretty huge field : http://en.wikipedia.org/wiki/Computational_finance and that if you try to roll your own, you are computing against a variety of math and CS phds that big trading firms hire to do analytics. |
