Date filed Issue number Description
2019-05-14 MLA-3100 "Publish" link on the Experiments list page is enabled for Experiments that have never fit a model
2019-05-13 MLA-3070 KernelPCA/KernelRidge only gets up to 1000 results

2019-03-28 MLA-2965 "Edit Job Settings" does not work in Assistants
2019-03-24 MLA-2945 DensityFunction does not support the "as" clause
2019-03-19 MLA-2934 Need to document the semantics of DensityFunction parameters in mlspl.conf.spec
2019-03-13 MLA-2920 DensityFunction - IsOutlier and BoundaryRanges are blank if split by fields are numeric

Workaround:
As long as one of the split by fields are non-numeric all should work fine. 
| inputlookup my-data.csv | eval field2="_".field2 | fit DensityFunction field1 by "field2,field3,field4" into MyDensityFunction
2019-01-22 MLA-2818 Experiment Alerts created before MTLK 4.2.0 may be inaccurate on re-save if the user has modified the trigger condition

Workaround:
If the user has changed the trigger condition of their Experiment alerts from the one originally set when the alert was created, they should visit the Experiment's alerts (via Manage -> Manage Alerts) on the Experiments list after saving the experiment for the first time in MLTK 4.2.0 and confirm that the alert is configured as expected.
2018-09-24 MLA-2547 Experiments can't be renamed until they have been filled and saved

Workaround:
Load the Experiment, fill all necessary fields, and save it. You'll be able to rename the Experiment in the Save dialog.
2018-06-12 MLA-2258 TFIDF returns a vague error message when the "token_pattern" parameter is invalid
2018-04-18 MLA-2147 search.log does not show tracebacks on Windows on Splunk 7.1

Workaround:
The user can still look at the logs on windows in mlspl.log which captures the traceback. However, many users may not have access to mlspl.log (as it is indexed in the _internal index which normal users don't have by default). If this is the case, they will need to ask their Splunk administrators for access to this index.
2017-08-25 MLA-1916 Uncaught StatsModels error with ARIMA order=0-2-0
2017-02-28 MLA-1670 "Outliers Over Time" plot doesn't display any data if the _time field does not contain a Unix timestamp.
