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.

Size

How large the model is and how much data it was trained on. Parameters are the figure that decides whether it fits on a given graphics card.

Parameters
12.2M

None given but it does say " Since each non-leaf node in a tree has its own feature vector, the number of free parameters associated with the tree is linear in this quantity", and the largest model (T7: ADAPATIVE(0.4) x 4) has 121980 of them. The feature vectors are 100-dimensional. I've done the dubious thing of multiplying the two to give an estimate.

Training data

"The dataset consists of a 14 million word training set"

What the numbers mean

What this model is

ADAPTIVE NLPM was published by University of Toronto, in Canada, in December 2008. academia is the category the publisher falls under.

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

Its weights were never published, so it can only be reached through its provider. No graphics card changes that.

How it was trained

The training set ran to roughly 14,000,000 tokens.

Answers

ADAPTIVE NLPM — common questions

01

How many parameters does ADAPTIVE NLPM have?

ADAPTIVE NLPM has 12.2M parameters. None given but it does say " Since each non-leaf node in a tree has its own feature vector, the number of free parameters associated with the tree is linear in this quantity", and the largest model (T7: ADAPATIVE(0.4) x 4) has 121980 of them. The feature vectors are 100-dimensional. I've done the dubious thing of multiplying the two to give an estimate. 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.

02

Who created ADAPTIVE NLPM?

ADAPTIVE NLPM was published by University of Toronto, based in Canada, categorised as academia.

03

When was ADAPTIVE NLPM released?

ADAPTIVE NLPM was published in December 2008. Capability per parameter has improved considerably since, so a newer model of the same size is often the better use of the same hardware.

04

What is ADAPTIVE NLPM used for?

ADAPTIVE NLPM works in Language, and is recorded as handling language modeling. 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.

05

What GPU do I need to run ADAPTIVE NLPM?

None. ADAPTIVE NLPM 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.

06

Is ADAPTIVE NLPM open source?

No. ADAPTIVE NLPM has not had its weights published, so it exists only as a service controlled by its owner.

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.
