LoadJson not implemented

[SujataZ]

Can anyone help on this please?

I am trying to save model & then load it.
Tried using the other way of serializing as in the "tests" code, that gives error as

Unable to cast object of type 'System.Collections.Generic.Dictionary`2[System.String,System.Object]' to type 'numl.Supervised.NaiveBayes.DecisionTreeModel'.

I got it working by saving in file only, instead of database.
"LoadJson" implementation would have been a great help to avoid all this coding.

Sorry about that!! Excellent point. I will work on it. Thanks so much for the feedback.

Thanks, and this is a great machine learning library, looking forward to see more in it :)

Also see 3414fb4 for actual Json save and load code (along with supporting tests). This really needed to be fixed: thanks for the push! It should be up on nuget as build 0.9.15-beta.

Hey Seth, after upgrading to "0.9.15-beta", I do not see the method "LoadJson" on model, can you please help?

[sethjuarez]

Hi Sujata!
It didn't make sense to put it on an instance of a model so I added it to the JsonReader class as a static method (see: https://github.com/sethjuarez/numl/blob/dev/Src/numl/Serialization/JsonReader.cs#L347-L352).

var dt = JsonReader.ReadJson<DecisionTreeModel>(json);

What do you think about this?

Kudos Seth, it's working as expected now,
thanks.
