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.

Task
Pattern recognition

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
0K

"The machine's total experience is stored in the values of the weights a0,...,a16"

Training data
100 tokens

"The best system, arrived at by slow precise adaptation on the full body of 100 noisy patterns, was able to classify these patterns as desired except for twelve errors." https://isl.stanford.edu/~widrow/papers/c1960adaptiveswitching.pdf

Training compute

The arithmetic performed to train the model, measured in floating-point operations. It is a measure of what the training run cost, not of how fast the finished model answers you.

Training compute
6.6 × 10³ FLOP

"The method of searching that has proven most useful is the method of steepest descent" Apparently each pattern was only shown once to the system. So the training compute is (forward pass compute) * (3 for backprop) * dataset size This is a single layer (and single neuron) which does not require gradients w.r.t. inputs - 1:1 forward-backward ratio

What the numbers mean

About this model

ADALINE was published by Stanford University, in United States of America, in June 1960. The organisation is categorised as academia.

It works in Vision, and is recorded as doing pattern recognition.

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 run consumed about 6.6 × 10³ FLOP. That figure describes the cost of creating it and has no bearing on how quickly it generates text.

It was trained on about 100 tokens of text.

Its inclusion criterion is highly cited.

Answers

ADALINE — common questions

01

What is ADALINE used for?

ADALINE works in Vision, and is recorded as handling pattern recognition. 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

How much compute was used to train ADALINE?

Around 6.6 × 10³ FLOP. That measures what producing the model cost and says nothing about how quickly it answers once trained — inference speed comes from memory bandwidth, not from the training budget.

03

What GPU do I need to run ADALINE?

None. ADALINE 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.

04

Is ADALINE open source?

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

05

How many parameters does ADALINE have?

ADALINE has 0K parameters. "The machine's total experience is stored in the values of the weights a0,...,a16". 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.

06

Who created ADALINE?

ADALINE was published by Stanford University, based in United States of America, categorised as academia.

07

When was ADALINE released?

ADALINE was published in June 1960. 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.
