Abstract: Certain aspects of the disclosure provide systems and methods for detecting hallucinations in machine learning models. A method generally includes generating a potential answer from an initial prompt received from a user. The method generally includes interrogating the machine learning model with a verification prompt formulated to elicit a positive or negative response from the machine learning model based on the potential answer and initial prompt. A negative response by the neural network model to the verification prompt is indicative of the potential answer being a hallucination. A positive response by the neural network model to the verification prompt is indicative of the potential answer being free from a hallucination. The method generally includes outputting to the user the potential answer as a final answer upon receiving a positive response to the verification prompt.

Abstract: Certain aspects of the present disclosure provide techniques for managing a search engine based on search performance metrics. An example method generally includes dividing a set of search history data into a first subset of search history data and a second subset of search history data. The first subset of data is associated with interaction with search results, and the second subset of data is associated with non-interaction with search results. A first quality score is generated for searches in the first subset of data. A second quality score is generated for searches in the second subset of data based on different search intents identified for each temporally related group in the second subset of data. An overall quality score is generated for a search engine, and one or more actions with respect to the search engine are taken based on the overall quality score.

Abstract: Systems and methods for a boosted Latent Dirichlet Allocation model with predefined clusters and repelling force. Herein, clusters are pre-populated with seed words with amplified weights to predefine the characteristics of clusters. A repel force is also applied while assigning words to specific clusters in order to assign words more accurately to clusters in instances where clusters have similar characteristics. In addition to generating improved clustering of words, systems and methods may analyze words within queries to provide explainability output related to the performance of content or data.

Abstract: A humanoid mannequin with jointed, positionable, and realistic reactive limbs. The mannequin is used in connection with sparring, self-defense, law enforcement, and combat sports training. The mannequin is constructed with a jointed endoskeleton frame that permits the mannequin limbs to be positioned in various training postures, and to realistically hold such positions against external forces exerted by a combatant. The mannequin skeleton also includes a series of elastic elements that allow the skeleton to be forced from its preset posture, and to recover that posture once the disturbing force is removed. The mannequin skeleton is covered by a durable flexible elastomer skin filled with a resilient supporting foam. This housing material provides the external anatomical features of a human body as well as the padding required to protect combatant users from the internal rigid skeletal components.
