That explanation is quite useful after having some basic understanding of TFT architecture. So reading the original manuscript beforehand is somehow recommended to get the essence from this video.

Is the Variable Selection technique is robust to high concurvity; non-cointegrating relationships; varying degrees of persistence amongst predictors ; pattern destroying non-stationarity (EMH) etc etc

I would think generally not. I mean that is your most general data science problem, how do you predict stuff that is wildly different from the past data that you have seen. Now, that doesn't mean that it isn't somewhat tracking, since the latest data does go in and most forecasts will be somewhat guided by the latest "is" state. The fact that you typically predict over many entities, you would also hope that some generalisation would naturally occur as some similarities have been already observed in other entities. Now these models are not truly causal, at least not out of the box. And they can't, because causality cannot be inferred from data (caveats caveats caveats). So it does fall back to the modeller to provide sensible covariates. As long as causal pathways don't break down (and sometimes that can happen, at least temporarily) the model generalises. If one only throws features at the model and hopes it finds all it needs by itself, one might be in for a bad surprise.

As Arvid showed us, TFT can be applied to forecasting tasks i.e. forecasting 30days in the future when we have 90days of past data. Can TFT be used to forecast 90days in the future when we have only 30 days past data? Looks like it’s impossible because of TFT architeture, but I’d really like to know your answer to that question.

I'm using it to forcast 4 quarters ahead, having the present data only. It's working pretty well, I'm building my startup around this.
