Deep Multitask NLP Network

Closed weights NEC Laboratories 1.5M parameters July 2008

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.

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
1.5M

With a word vector size of 50 and a vocabulary size of 30,000, the embedding matrix has 1,500,000 parameters. There are also some small convolutional and dense layers with far fewer parameters.

What the numbers mean

Where it came from

Deep Multitask NLP Network was published by NEC Laboratories, in United States of America, in July 2008. The organisation is categorised as industry.

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

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

What went into building it

It was trained on about 633,000,000 tokens of text.

Its inclusion criterion is highly cited,SOTA improvement.

Answers

Deep Multitask NLP Network — common questions

01

Is Deep Multitask NLP Network open source?

The licensing for Deep Multitask NLP Network was never recorded in our source data. We treat unstated licensing as closed, because an unrecorded licence is not one to rely on.

02

How many parameters does Deep Multitask NLP Network have?

Deep Multitask NLP Network has 1.5M parameters. With a word vector size of 50 and a vocabulary size of 30,000, the embedding matrix has 1,500,000 parameters. There are also some small convolutional and dense layers with far fewer 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.

03

Who created Deep Multitask NLP Network?

Deep Multitask NLP Network was published by NEC Laboratories, based in United States of America, categorised as industry.

04

When was Deep Multitask NLP Network released?

Deep Multitask NLP Network was published in July 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.

05

What is Deep Multitask NLP Network used for?

Deep Multitask NLP Network 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.

06

What GPU do I need to run Deep Multitask NLP Network?

None. Deep Multitask NLP Network 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.

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.
