madlib git commit: 1.13 Upgrade and MLP IC fix
Repository: madlib
Updated Branches:
refs/heads/master cf0d4ebff -> 0fdf136b4
1.13 Upgrade and MLP IC fix
JIRA: MADLIB-1197
Additional Author: Nandish Jayaram <nj...@apache.org>
- 1.13 Upgrade does not drop the kNN help functions even though their
return types are changed. This commit adds the missing functions to the
changelist and alters the upgrade_util.py_in so that functions without
arguments can be dropped.
- Some assert thresholds are too strict for MLP in IC. This commit relaxes
those thresholds.
Closes #224
