Classify, Predict, PredictorMeasurements, and ClassifierMeasurements objects not displaying properly

[Hachann]

Hi everyone,

It appears that the functions Classify, Predict, PredictorMeasurements, and ClassifierMeasurements do not display their contents correctly in WLJS. I've also tried using MMAView on their outputs, but it doesn't produce any meaningful output either.

These functions typically return symbolic objects that include a summary of the classifier or predictor's performance on the provided dataset. In desktop Mathematica or the notebook interface, these objects show a formatted summary by default.

However, in WLJS, no such summary is rendered — the output a big chunk of text with warnings about its size.

That said, individual properties can still be accessed and displayed correctly. For example, calling ["RSquared"] on a PredictorMeasurements object works as expected.

Also, when using Classify or Predict without ; at the end of the line forces the loss of WLJS GUI and instead shows some Wolfram Language back-end stuff in big fonts, e.g. :

I can imagine that. Probably the raw expression contains a lot of data involving machine-learning parameters. Then Kernel tries to convert it to the input form string and just runs out of memory for a string or something.

We shall fix it by making a proper summary box form for such symbols in the next release (probably at wljs-neuralnet module)
