Machine Learning Wars: Amazon vs Google vs BigML vs PredicSis

Comparing 4 Machine Learning APIs: Amazon Machine Learning, BigML, Google Prediction API and PredicSis on a real data from Kaggle, we find the most accurate, the fastest, the best tradeoff, and a surprise last place. By Louis Dorard UPDATE - NEW BIGML RESULTS: As pointed out by Francisco Martin, if you just change the objective field (SeriousDlqin2yrs) to be numeric instead of categorical, BigML's accuracy for a single model goes to 0.853 (whereas it was initially reported as 0.790 - the accuracy in the table above and the Kaggle rank below have been updated to reflect that). Amazon ML (Machine Learning) made a lot of noise when it came out last month. Shortly afterwards, someone posted a link to Google Prediction API on HackerNews and it quickly became one of the most popular posts. Google's product is quite similar to Amazon's but it's actually much older since it was introduced in 2011.
