Transformer-XL + RMS dynamic eval

Closed weights University of Edinburgh 257M parameters April 2019

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

How it is classified

Labels the source dataset applies when tracking notable models, and how confident it is in the entry.

Why it is tracked
SOTA improvement

"By applying dynamic evaluation to Transformer-XL models, we improve the state of the art on enwik8 from 0.99 to 0.94 bits/char, text8 from 1.08 to 1.04 bits/char, and WikiText-103 from 18.3 to 16.4 perplexity points."

What the numbers mean

Where it came from

Transformer-XL + RMS dynamic eval was published by University of Edinburgh, in United Kingdom of Great Britain and Northern Ireland, in April 2019. The organisation is categorised as academia.

It works in Language, and is recorded as doing language modeling/generation.

Because the weights are not available, none of the hardware figures elsewhere on this site apply to it.

What went into building it

The training set ran to roughly 103,000,000 tokens.

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

Answers

Transformer-XL + RMS dynamic eval — common questions

01

What is Transformer-XL + RMS dynamic eval used for?

Transformer-XL + RMS dynamic eval works in Language, and is recorded as handling language modeling/generation. A model can carry several of each, so these are the areas it was built for rather than a limit on what it will attempt.

02

What GPU do I need to run Transformer-XL + RMS dynamic eval?

None. Transformer-XL + RMS dynamic eval 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.

03

Is Transformer-XL + RMS dynamic eval open source?

No. Transformer-XL + RMS dynamic eval has not had its weights published, so it exists only as a service controlled by its owner.

04

How many parameters does Transformer-XL + RMS dynamic eval have?

Transformer-XL + RMS dynamic eval has 257M parameters. That figure is the total, and it is what decides how much memory the model needs — roughly half a gigabyte per billion at the compression most people use.

05

Who created Transformer-XL + RMS dynamic eval?

Transformer-XL + RMS dynamic eval was published by University of Edinburgh, based in United Kingdom of Great Britain and Northern Ireland, categorised as academia.

06

When was Transformer-XL + RMS dynamic eval released?

Transformer-XL + RMS dynamic eval was published in April 2019. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

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.
