(*includes changes from Novikov release [2.8.5.3] - 3/7/15)
####New Features These changes represent features that have been added since the previous release:
- Create mechanism to move VMs between Hypervisor (HEX-1965)
####Enhancements
These changes are improvements to existing features (which includes changed default values):
#####Algorithms
- Enforce
min_rowsinput parameter for leaf nodes in tree builder (github) - Enable variable importances for autoencoder (github)
- GLM coefficient constraints (HEX-1961)
- added grid search across all relevant parameters that might be affected by beta constraints (github)
- added stricter threshold in checkmodel, and added higher accuracy by default (github)
- Added proximal penalty to objective value used in line search (github)
- try different setting for importance (github)
- add some tolerance (github)
- Write trees to individual files for easier debugging (github)
#####API
#####System
- add UUID field to generated POJOs in h2o1 (HEX-2014) (github)
- allow column type setting (HEX-1291)
- Need a way to set a specific level on a factor col (PUB-1153)(github)
- Bind both TCP and UDP ports before clustering (github)
- Removes all GA messages (github)
####Bug Fixes These changes are to resolve incorrect software behavior:
#####Algorithms
- GLM : the proximal penalty was not being added to the objective value used during line-search, which would cause line search to stop the solver prematurely. (HEX-2028)
- GLM : With some Bayesian priors, the coeff estimates are off from our expectation: (HEX-2026)
- GLM : Modeling with constraints delivers unexpected results (HEX-2025)
- GLM in R: h2o.glm with Beta Constraints overwrites input training frame (HEX-2021)
- GLM: linear regression fails to run with beta constraints (HEX-2020) (github)
- java.lang.ArrayIndexOutOfBoundsException while running GBM (HEX-2011)
- i pass "do_classification: True" parameter to ModelBuilders/gbm. no error. but it's not echoed and the result is regression (PUB-1134)
- Fixed proximal interface in glm (github)
- GLM bug fix (github)
- Bug fix in glm to protect against (throw IAE) user supplying beta_given but no vector of penalties in the beta_constraints (github)
