Answers
Polarity Classifier — common questions
When was Polarity Classifier released?
Polarity Classifier 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.
What is Polarity Classifier used for?
Polarity Classifier works in Language, and is recorded as handling text classification. Models frequently carry more than one of each, and the tags describe purpose rather than capability limits.
What GPU do I need to run Polarity Classifier?
None. Polarity Classifier 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.
Is Polarity Classifier open source?
The licensing for Polarity Classifier was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.
How many parameters does Polarity Classifier have?
No parameter count has been published for Polarity Classifier, which is why no memory or speed figure appears on this page.
Who created Polarity Classifier?
Polarity Classifier was published by University of Edinburgh,University of Pittsburgh, based in United Kingdom of Great Britain and Northern Ireland, 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.
