Abstract: A generative language model, such as an LLM, may “hallucinate,” such that it provides an output category that is incorrect or not relevant to its input. One solution is to use semantic replacement after the generative language model finishes outputting the category. A prompt may be provided to a generative language model, the prompt instructing the generative language model to generate output that classifies an input to the generative language model. Output may be received from the generative language model, the output classifying the input into a category. It may be determined that the category is an invalid category. A valid category be obtained based on the invalid category. The invalid category may be substituted with the valid category.

Abstract: A carbon-coated nickel oxide nanocomposite material, its preparation, and application thereof are provided. The nanocomposite material contains carbon-coated nickel oxide nanoparticles having a core-shell structure including an outer shell that is a graphitized carbon film optionally doped with nitrogen and an inner core comprising nickel oxide nanoparticle(s). The nanocomposite material has a carbon content of from greater than 0 wt % to not greater than about 5 wt %, based on the weight of the nanocomposite material.

Abstract: A computer-implemented method and system for optimally retraining a supervised machine learning model based on newly received data. The method comprises receiving, from a requestor device, a new data set for updating a previously-trained model generated using a first training data set and tested using a first testing data set. Then, the new data set is checked for components having an association to both the first training data set and the first testing data set; and where such components are found, they are deleted. Once all of the components of the new data have been examined, remaining components of the new data set are assigned to one of the first training or testing data set in dependence upon a relationship connectivity therewith to form at least one of an updated testing and training data set for building the updated model.

Abstract: A nanocomposite has a core-shell structure with an outer shell and an inner core. The outer shell is a graphitized carbon film, and the inner core contains nickel oxide and alumina, with a nickel oxide content of 59%-80%, an alumina content of 19%-40%, and a carbon content of not more than 1%, based on the total weight of the nanocomposite. The process for catalytic combustion of volatile organic compounds may utilize the nanocomposite as a catalyst.

Abstract: The fine-tuning of a machine learning model in a protected environment. Input (e.g., training data) received from the tune initiator system that instructs the tuning occur is received over a channel that is visible to the tune initiator system. Proprietary input is received from another party over a secure connection that is not visible to the tune initiator system. These inputs are then used to fine-tune a machine learning model to thereby form a fine-tuned machine learning model. The resulting fine-tuned machine learning model is then stored in the protected environment such that the fine-tuned machine learning model is available for the tune initiator system to provide input data to and receive output data from, but such that the tuned model cannot be directly accessed by the tune initiator system.

Abstract: A planar transformer, a power conversion circuit, and an adapter, is provided to improve noise suppression performance. The planar transformer includes a magnetic core and a printed circuit board (PCB) winding board, where the PCB winding board includes a primary winding, a secondary winding, a shielding winding, and a compensation winding. In embodiments of this disclosure, the shielding winding and the compensation winding that has a plurality of turns of coils are disposed between the primary winding and the secondary winding of the planar transformer. The shielding winding can shield electric field coupling between the primary winding and the secondary winding, thereby suppressing a noise current between the primary winding and the secondary winding. Common mode noise generated by the compensation winding cancels common mode noise flowing to the secondary winding or the primary winding, to minimize common mode noise of an entire system.
