Hi all, here is summary for the last week.
1. Continued to fix bugs and broken tests in transformer #4285 and got the pr merged. 2. Added pipeline (#4317), where multiple transformers and machines can be chained and work together. Added meta examples and cookbook of pipeline (#4323) 3. Ported a few meta examples using factory api (#4318). 4. Refactored machine api (fit + predict) . This is a heavy refactor, I will start from linear machines and iterative a few times. This task will be continued this week. Cheers Wuwei
