Low precision in MAHOUT-228 tests (online logistic regression)

2010-01-18 Thread Olivier Grisel
Hello, I am currently testing the MAHOUT-228-3.patch applied to the current trunk. The merge went mostly well except a couple of duplicated chunks in the patchs (probably applied otherwise to the trunk) and a duplicated wordlist. However to make the tests pass I add to reduce the precision of

THANK YOU. I have been very grumpy that I couldn't get to doing this yet. I will coordinate closely with you. I haven't used git yet in anger so it will be a learning experience. Don't expect me to have time, though. ( I will try ... but expect not to find a hole ) On Mon, Jan 18, 2010 at
