Dear committers, I am feeling that my contributions are not in an ordered way. So, I am listing them here. And, also listed the help required from volunteers.
1. [SYSTEMML-1437] - factorization machines <https://github.com/apache/systemml/pull/526> [*in progress*] - till now, I have implemented the `*fm.dml*` core module. - *Help: *I am unclear as to how the `i/o` will be for the example implementations, such as regression. A sample script for this, might help me complete all the examples *regression*, *classification*, & *ranking*. 2. [SYSTEMML-1645] - Verify whether all scripts work with MLContext & automate <https://github.com/apache/systemml/pull/589> [*in progress*] - This PR tries to write the test scripts for all top level algorithms for the new MLContext. - I am working with *Jerome* on this. Once he verifies all the scripts, I will add the tests for them. - *Help: *Can any body help review this PR, and suggest what is missing in this PR. I am getting script execution failures. 3. [SYSTEMML-1444] - UDFs w/ single output in expressions <https://github.com/apache/systemml/pull/603> [*in progress*] - The objective is to make udf's callable from expressions. I've gone through all the Hop, Lop implementations, compiler, parser, api to have a clear picture. - I am still making my way through this. - *Help: *Hi Matthias, I tried implementing a lop *FunctionCallCPSingle.java <https://github.com/apache/systemml/pull/603/files#diff-1fb71e441518b2859963b386b1869711> * 4. [SYSTEMML-1216] - implement local svd( ) function <https://github.com/apache/systemml/pull/605> [*done*] - With previously implemented local svd(), I've added little improvements and tests. - *Help: *This is ready to be merged. (I believe) 5. [SYSTEMML-1214] Implement scalable version of singular value decomposition <https://github.com/apache/systemml/pull/612> [*issue with the testing?*] - This PR depends on the above PR, this implements distributed svd based on already implemented distributed qr() and then calculates local svd() of then obtained R matrix. - *Help: *I have implemented it preliminarily, but how should I test for scalability, Can I do that on *Jenkins CI*. or Do I need to run that on any cluster. 6. [SYSTEMML-979] Add support for Bayesian Optimization. <https://github.com/apache/systemml/pull/632> [*a lot to be done*] - There's a lot of work in progress, but I implemented a skeleton with bad syntax. ( I'll improve this soon) - many improvements have to be done, better operation needs to be kept and loops needs to be completely eliminated. Thanks all for the support, Janardhan
