Appl. No.:

09/925218

Assignee:

E-Centives, Inc. - Bethesda MD

International Classification:

G06F017/30

US Classification:

707 10, 707103 R

Abstract:

A computer-implemented approach for organizing input listings from various sources of input listings. Input listings are organized by mapping the input listings to consolidated listing that correspond to the input listings. The mapping of the input listings are based on various techniques such as a Stock Keeping Unit item-listing-to-consolidated-listing matching technique, a name/title item-listing-to-consolidated-listing matching technique, and a model item-listing-to-consolidated-listing matching technique.

International Classification:

G06F007/00

US Classification:

701036000, 701117000

Abstract:

The present invention provides an intelligent and efficient system () and/or method () for automatic notification and/or enforcement of legal traffic speed limits and stops, comprising roads, streets, highways, construction zones, accident sites, and anywhere needed () installed at appropriate advanced locations with information tags () written with information including the according speed limit and/or stop information and vehicles () installed or built-in with information readers () capable of wirelessly and automatically reading information from the information tags () while the vehicles () travel. The read and other on-the-road information is displayed on visual displays () inside vehicles () and/or is voiced via audio devices () inside vehicles () for automatically notifying the vehicle drivers. Furthermore the in-vehicle speed control systems () use the speed limits read in by the information readers () to automatically enforce vehicles () to travel only within the speed limits.

International Classification:

G06N 3/08
G06N 3/04

Abstract:

An improved electronic communication system schedules transmission of electronic communications based on a predicted open time and click time. The open and click times are predicted from a machine learning model that is trained to optimize for both tasks. Additionally, when training the machine learning model, the loss used for adjusting the system to achieve a desired accuracy may be a biased loss determined from a function that penalizes overpredicting the open time. As such, the loss value may be determined by different set of rules depending on whether the predicted time is greater than the actual time or not.

International Classification:

G06Q 30/06
G06K 9/62

Abstract:

The present disclosure relates to systems, methods, and non-transitory computer readable media that utilize collaborative filtering and a reinforcement learning model having an actor-critic framework to provide digital content items across client devices. In particular, in one or more embodiments, the disclosed systems monitor interactions of a client device with one or more digital content items to generate item embeddings (e.g., utilizing a collaborative filtering model). The disclosed systems further utilize a reinforcement learning model to generate a recommendation (e.g., determine one or more additional digital content items to provide to the client device) based on the user interactions. In some implementations, the disclosed systems utilize the reinforcement learning model to analyze every negative and positive interaction observed when generating the recommendation. Further, the disclosed systems utilize the reinforcement learning model to analyze item embeddings, which encode the relationships among the digital content items, when generating the recommendation.
