Publication number: 20210397630Abstract: A real-time messaging platform and method is disclosed which classifies messages in accordance with a combination of user engagement events as modified to reflect the temporal structure of the user engagement events. A message can be assigned a metric based, for example, on a weighted combination of user engagement rates, decayed with time to reflect an intuition that recent interactions by one or more users with the message will have a greater impact than older interactions with the message. Different types of interaction by one or more users with the message can be assigned different weights when the different engagement events are combined and, also, can be assigned different temporal characteristics.Type: ApplicationFiled: April 5, 2021Publication date: December 23, 2021Inventors: Ashish Goel, Srinivasan Rajgopal, Utkarsh Srivastava, Anamitra Banerji

Publication number: 20210374386Abstract: Aspects of the current disclosure include systems and methods for identifying an entity in a query image by comparing the query image with digital images in a database. In one or more embodiments, a query feature may be extracted from the query image and a set of candidate features may be extracted from a set of images in the database. In one or more embodiments, the distances between the query feature and the candidate features are calculated. A feature, which includes a set of shortest distances among the calculated distances and a distribution of the set of shortest distances, may be generated. In one or more embodiments, the feature is input to a trained model to determine whether the entity in the query image is the same entity associated with one of the set of shortest distances.Type: ApplicationFiled: April 15, 2021Publication date: December 2, 2021Inventors: Pranav Dandekar, Ashish Goel, Peter Lofgren, Matthew Fisher

Publication number: 20210133815Abstract: A real-time messaging platform and method are disclosed which can be used to promote content in the messaging platform. In one embodiment, the promotion system is disclosed which performs initial candidate selection so as to narrow down the set of candidate promotions before applying more expensive processing. The candidate selection takes advantage of the connection graph information associated with accounts in the messaging platform to identify targeted accounts. In another embodiment, the promotion system uses a prediction model to predict a user's engagement with the promotion and utilizes the prediction to assist in ranking the candidate promotions. Promotions can be assigned metrics based, for example, on a weighted combination of user engagement rates, decayed with time to reflect an intuition that recent interactions by one or more users with the promotion will have a greater impact than older interactions with the promotion.Type: ApplicationFiled: October 12, 2020Publication date: May 6, 2021Inventors: Utkarsh Srivastava, Ashish Goel, Srinivasan Rajgopal, Anamitra Banerji

Patent number: 10957565Abstract: Embodiments include systems, devices, and methods for monitoring etch or deposition rates, or controlling an operation of a wafer fabrication process. In an embodiment, a processing tool includes a processing chamber having a liner wall around a chamber volume, and a monitoring device having a sensor exposed to the chamber volume through a hole in the liner wall. The sensor is capable of measuring, in real-time, material deposition and removal rates occurring within the chamber volume during the wafer fabrication process. The monitoring device can be moved relative to the hole in the liner wall to selectively expose either the sensor or a blank area to the chamber volume through the hole. Accordingly, the wafer fabrication process being performed in the chamber volume may be monitored by the sensor, and the sensor may be sealed off from the chamber volume during an in-situ chamber cleaning process. Other embodiments are also described and claimed.Type: GrantFiled: July 28, 2020Date of Patent: March 23, 2021Assignee: Applied Materials, Inc.Inventors: Shimin Mao, Simon Huang, Ashish Goel, Anantha Subramani, Philip Allan Kraus

Publication number: 20200412680Abstract: A system and a method are disclosed for recommending electronic messages in a message sharing system. Users can post messages to the message sharing system. These messages from posting users are received by the system and sent to receiving users that have subscribed to the posting users. The receiving users interact with the messages in various ways, such as by sharing the messages with other users. Interaction information is received for each of the electronic messages. The interaction information includes an indication of the number of interactions with the electronic message by receiving users. A score is determined for each electronic message based on the interaction information. Electronic messages are selected for being recommended to a user or a group of users based on the scores. The recommendations are then sent to the users, enabling users to better focus their attention on messages that are likely to be interesting.Type: ApplicationFiled: September 14, 2020Publication date: December 31, 2020Inventors: Abdur Chowdhury, Ashish Goel, Ram Ravichandran

Publication number: 20200242492Abstract: Embodiments herein use transfer learning paradigms to facilitate classification across entities without requiring the entities access to the other party's sensitive data. In one or more embodiments, one entity may train a model using its own data (which may include at least some non-shared data) and shares either the scores (or an intermediate representation of the scores). One or more other parties may use the scores as a feature in its own model. The scores may be considered to act as an embedding of the features but do not reveal the features. In other embodiments, parties may be used to train part of a model or participate in generating one or more nodes of a decision tree without revealing all its features. The trained models or decision trees may then be used for classifying unlabeled events or items.Type: ApplicationFiled: January 25, 2019Publication date: July 30, 2020Applicant: Stripe, Inc.Inventors: Ashish GOEL, Peter LOFGREN
