The end of Chapter 1 indicates we may expect to see a chart showing 3 different learning rates, and also that the classifications for the first two data points will be a "1" and "0", with predicted values of >~0.5 and <~0.1 respectively.

However, execution of the tests (just before today's update that appears to have broken some things), results in two classifications of "0" for those same data points, and predicted values of ~0.46 and ~0.25.

I also notice the text indicates the nIters would be output, but this is also not the case.

Note, the chapter also indicated an EPS of 0.02, which is invalid in the current limits (<0.01 required). I also tried ETA of 0.0005, and got closer results.
