Abstract: Provided herein is a novel method named Knowledge-Constrained Tree Search Decoding (KCTS) is provided, which is a first discriminator-guided constrained decoding approach to knowledge-grounded generation. The KCTS method also employs a Monte-Carlo Tree Search decoding (MCTS) instead of conventional LM decoding methods, which re-orders each token's importance based on the estimated future faithfulness starting from that token with multiple simulations. Coupled with a novel token-level hallucination detection method, RIPA (Reward Inflection Point Approximation), trained to predict the starting point of the hallucinating token, enabling effective adaptation of the knowledge classifier defined on the sequence level to the token level, this novel method is able to greatly mitigate hallucination problems of LLMs without the need of fine-tuning, thereby preventing the incurrence of high computational costs.

Abstract: Provided herein is a method of improved commonsense knowledge bases reasoning through constraint-based prompting. A novel dual-module constraint-based prompt engineering system named ConstraintChecker is involved, which employs a first rule-based module to produce a list of constraints and a second zero-shot learning module to check whether the knowledge instance satisfies all constraints. The acquired constraint-checking result is then aggregated with the output of the main prompting backbone to produce the final output. This present method is more effective in commonsense knowledge bases reasoning then that by employing the prompting backbone alone, and also significantly reduces computational costs.

Abstract: A system using global and local-aware denoising framework for commonsense knowledge graph noise detection is provided. The system includes an input receiver, a triple encoder, a global noise detector, a local noise detector, and a comprehensive evaluation scorer. The triple encoder receives the CSKG information from the input receiver and extract semantic information from free-text formatted nodes in the CSKG information, so as to obtain structured triples. The global noise detector identifies high-frequency patterns through rule mining and uses a rule encoder to generalize learned rules and guide noise detection. The local noise detector utilizes the structured triples output by the triple encoder to aggregate neighboring triple information around both the head and tail nodes via graph networks. The comprehensive evaluation scorer provides a comprehensive score based on global noise detection and local noise detection, so as to indicate a noise level for the CSKG information.

Abstract: This document describes techniques and systems that enable autocalibration for multiple cameras using near-infrared (NIR) illuminators. The techniques and systems include a user device that uses NIR images, including dot images and flood images, captured by the multiple cameras. The user device implements an autocalibration module that normalizes the contrast of each image. Then, the autocalibration module detects dot features in the dot images and detects flood features in the flood images. The autocalibration module uses the flood features to disambiguate the dot features in the dot images. Then, the autocalibration module uses the disambiguated dot features to determine new calibration parameters for recalibration of the multiple cameras. In some aspects, the autocalibration module uses the dot images, rather than the flood images, to detect the flood features for disambiguating the dot features.
