Publication number: 20250245425Abstract: Disclosed herein are systems and methods for improving the auto-generation of pipelined search query statements by a large language model (LLM) through a post processing. In some examples, such a method includes operations of receiving, by a post processing engine, a response to an auto-generated prompt from the LLM that includes programming code generated by the LLM, performing a post processing of a response from the LLM that includes the programming code generated by the LLM including performing an error correction process when a term of the programming code generated by the LLM is inconsistent with terms of a schema of the user, and generating a graphical user interface (GUI) that displays the response to the auto-generated prompt when the terms of the programming code generated by the LLM including any replacement terms are consistent with the terms of the schema.Type: ApplicationFiled: June 10, 2024Publication date: July 31, 2025Inventors: Khalil Ben Ayed, Leo Betthauser, Longbin Chen, Mahan Das, Vedant Dharnidharka, Haydn John Wiese, Rong Tan Wang, Seunghee Han, Julien Didier Jean Veron Vialard

Patent number: 7274822Abstract: Systems and methods for annotating a face in a digital image are described. In one aspect, a probability model is trained by mapping one or more sets of sample facial features to corresponding names of individuals. A face from an input data set of at least one the digital image is then detected. Facial features are then automatically extracted from the detected face. A similarity measure is them modeled as a posterior probability that the facial features match a particular set of features identified in the probability model. The similarity measure is statistically learned. A name is then inferred as a function of the similarity measure. The face is then annotated with the name.Type: GrantFiled: June 30, 2003Date of Patent: September 25, 2007Assignee: Microsoft CorporationInventors: Lei Zhang, Longbin Chen, Mingjing Li, Hong-Jiang Zhang
