I am starting off with machine learning so could someone tell if there is some site where one can find the current best performing trained models for any specific problem like sentiment analysis or objection detection or any machine learning problem of that sort?
It would be very convenient but I'm not aware of any such site.
Besides, it would be quite difficult to agree on what is the current best performing model in general, as this depends on the dataset, how it's been annotated and the evaluation method. Not to mention the multiplicity of languages, since a particular model is usually language specific. And of course it would be difficult to keep up with new methods and datasets being published constantly.
