International Classification:

G06N 3/04

Abstract:

Provided are systems and methods that improve the computational efficiency of Transformers or other attention-based neural networks or machine learning models by re-using a number of attention scores between layers and/or heads of the model. To reduce the computational cost of self-attention-based models while achieving comparable or even superior results, example aspects of the present disclosure propose a novel architecture that reuses attention scores computed in one layer in one or multiple subsequent layers.

Appl. No.:

17/367000

Inventors:

- San Francisco CA, US
Mary Reeder - Seattle WA, US
Joseph Bureau - Maple Valley WA, US
Frederick Liu - Oakland CA, US

International Classification:

H04W 12/63
H04W 12/06

Abstract:

A method for authentication using location correlation is disclosed. The method includes determining geographic zones and zone identifiers associated with a location of a mobile communication device. Later, transaction data is received and a zone identifier is determined from that transaction data. If the zone identifier matches one of the previously determined zone identifiers, then a match indicator is sent to an authorizing entity computer system or the transaction may be allowed to proceed.
