No hardware requirements for this model
The weights for this model have not been published, so it cannot be downloaded or run on your own hardware at any size. It is reachable only through its provider, and no graphics card changes that.
On record

What the numbers mean
What this model is
Polarity Classifier was published by University of Edinburgh,University of Pittsburgh, in the country recorded as United Kingdom of Great Britain and Northern Ireland, during September 2009. It comes out of an organisation categorised as academia,Academia.
It works in the domain of Language, and is recorded as performing the task of text classification.
Its weights were never published, so it can only be reached through its provider. No graphics card changes that.
Answers
Polarity Classifier — common questions
Polarity Classifier— when was it released?
It was published in September 2009. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.
Polarity Classifier— what is it used for?
It works in the domain of Language, and is recorded as handling the task of text classification. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
Polarity Classifier— what GPU do I need to run it?
None. This is a closed model — its weights were never published, so it cannot be downloaded or run on your own hardware at any price. It is reachable only through its provider.
Polarity Classifier— is it open source?
The licensing was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
Polarity Classifier— how many parameters does it have?
No parameter count has been published for it, which is why no memory or speed figure appears on this page.
Polarity Classifier— who created it?
It was published by University of Edinburgh,University of Pittsburgh, based in United Kingdom of Great Britain and Northern Ireland, an organisation categorised as academia,Academia.
The other direction
Looking at it from the other side?
This page starts from the model. If you already own a card and want to know everything it will run, start from the hardware instead.
