Context-dependent RNN

Closed weights Microsoft Research,Brno University of Technology July 2012

No estimate

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

Full specification

Everything on record for this model. Most of it describes how it was trained rather than how it runs — useful context for judging how much work went into it, and how it compares with models built at a different scale.

What the numbers mean

Where it came from

Context-dependent RNN was published by Microsoft Research,Brno University of Technology, in the country recorded as United States of America, during July 2012. It comes out of an organisation categorised as industry,Academia.

It works in the domain of Language, and is recorded as performing the task of language modeling.

This is a closed model: the trained values stayed with whoever produced them, and there is no local version to run.

Training and provenance

The training set ran to roughly 37,000,000 tokens of text.

It is tracked in the underlying dataset for one reason in particular: sOTA improvement.

Answers

Context-dependent RNN — common questions

01

Context-dependent RNN— 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.

02

Context-dependent RNN— 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.

03

Context-dependent RNN— who created it?

It was published by Microsoft Research,Brno University of Technology, based in United States of America, an organisation categorised as industry,Academia.

04

Context-dependent RNN— when was it released?

It was published in July 2012. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

05

Context-dependent RNN— what is it used for?

It works in the domain of Language, and is recorded as handling the task of language modeling. These are the areas it was designed around; they describe intent rather than a hard boundary.

06

Context-dependent RNN— 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.

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.
