Saul Workshop Issues

[kordjamshidi]

Here is a list of issues we faced when holding the workshop with @bhargav for the "Intro. to machine learning" class. A more formal feedback to come soon.

1- Running on Windows: (e.g. header files dependencies, and some other with unknown reason for us)
2- Validation set issue: (we need to address this explicitly in the data model population)
3- Learning curve: (a part of experimental analysis and evaluation and the whole visualization issue)
4- Parameter tuning/greedy search and more sophisticated techniques
5- Error messages on the WebApp: they were not informative about the source of error
6- WebApp: Import Errors with examples
7- Path to data: Data folder path consistency between webApp, sbt, intellij
8- Add links to scala tutorials: (a part of documentation)
9- Data storage with public access
10- Minor: updating data model syntax and naming

@bhargav I guess the Widows problem has been solved right? someone has a problem has an error with the header files in Windows still, any idea:

[trace] Stack trace suppressed: run last
saulExamples/compile:createHeaders for
the full output.
[error] (saulExamples/compile:createHeaders)
java.nio.charset.UnmappableCharacte
rException: Input length = 1
[error] Total time: 4 s, completed Jan 24, 2017 1:29:10 PM```

Looking at the issue.

In Windows, there is an environment variable for Java that needs to be set. I have updated the readme with instructions in PR #458
