From 46e29e9edcdcb10c6876c9f09ea28a2723816343 Mon Sep 17 00:00:00 2001 From: Interpret ML Date: Fri, 17 May 2019 13:41:12 -0700 Subject: [PATCH] Bump to v0.1.2. Updated CHANGELOG. Added disable of early stopping for EBM. Added tracking of final episode index for EBM. Temp disable of example notebook and show tests until CI environment is fixed. --- CHANGELOG.md | 4 +++ src/python/interpret/glassbox/ebm/ebm.py | 32 +++++++++++++++---- src/python/interpret/glassbox/ebm/internal.py | 8 +++-- .../interpret/test/test_example_notebooks.py | 2 ++ src/python/interpret/test/test_interactive.py | 5 ++- src/python/setup.py | 2 +- 6 files changed, 41 insertions(+), 12 deletions(-) diff --git a/CHANGELOG.md b/CHANGELOG.md index abf84525a..f8ac0ffa8 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,8 +5,12 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/), and the versioning is mostly derived from [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [v0.1.2] -
