Sorry about that, the RTF reader is from the Pyth library: http://pypi.python.org/pypi/pyth/
I think that's all that's needed. Thanks for taking a look! Zach On 11/08/2012 22:55, Robert Layton wrote:

The features I'm using are the tf-idf of set of text documents, correlated with human ratings assigned to each document. I'm thinking that I must be doing something wrong as the scores can't be that bad (not to mention negative?) If someone could have a look at it, I'd really appreciate it. I didn't upload to a github gist because they won't let me upload the dataset directory. So I've uploaded my really short code (regression.py) AND the original data set (/texts) here (625K): https://dl.dropbox.com/u/74279156/regression.zip This is my output: C:\python code\program>python regression.py loading texts... n_samples: 53, n_features: 6284 LinearRegresson [ 0.34662496 0.23446674 0.30332109 0.3163838 0.01607913] Accuracy: 0.24 (+/- 0.06) SVR linear [-0.05521329 -1.61280714 -0.67428098 -0.8805647 -2.20730703] Accuracy: -1.09 (+/- 0.37) SVR poly 4 degrees [-0.18814233 -1.78480475 -0.88158686 -1.05944432 -2.40284073] Accuracy: -1.26 (+/- 0.38) SVR sigmoid [-0.18814233 -1.78480475 -0.88158686 -1.05944432 -2.40284073] Accuracy: -1.26 (+/- 0.38) Please tell me what's wrong.. I'm dying to know how to get scikit-lean to predict based on this dataset.
