  • Publication number: 20250200330
    Abstract: An approach is provided for enhancing a generative large language model (LLM). An encoder, decoder, and generative associative memory network set are jointly trained to learn to store sentence encodings in a memory matrix used during decoding. The encoder and decoder are included in the generative LLM. The generative associative memory network set is included in an external memory unit. The external memory unit is external to the encoder and decoder. The generative LLM is augmented with the external memory unit in a framework that enhances the generative LLM. The external memory unit is updated with new information. Using the new information in the updated external memory unit, a knowledge update of the decoder is performed during an inference without fine-tuning or re-training the generative LLM. A response to a prompt during the inference is generated. The response is based on the knowledge update of the decoder.

  • Publication number: 20250005403
    Abstract: A computer-implemented method for discovering causality includes accessing time-series data describing past events. The time-series data is input into a machine learning model, the machine learning model implementing an intensity function including a kernel function, where the kernel function determines a causal strength value computed from a transformer model, and where the kernel function contributes to an additive function that sums intensity of repeated individual events of the past events. In response to the inputting, an output is received from the machine learning model that indicates a causality that links two or more events of the past events.

  • Publication number: 20240193411
    Abstract: An embodiment for generating causal association rankings for candidate events within a window of candidate events using dynamic deep neural network generated embeddings. The embodiment may automatically receive a window of candidate events including events of a first type preceding one or more target events of interest. The embodiment may automatically generate contrastive windows of candidate events, each of the contrastive windows of candidate events of the first type corresponding to a different dropped candidate event from the received window of candidate events. The embodiment may automatically identify matching historical windows of events having resulting embeddings that are close in distance to the embeddings corresponding to the embeddings of the contrastive windows and calculate a first score for each match. The embodiment may automatically identify matching incident windows and calculate a corresponding second score.

  • Patent number: 11676075
    Abstract: A computer-implemented method, a computer program product, and a system for reducing labeled sample quantities required to update test sets. The computer-implemented method includes inputting a portion of unlabeled production data into a base model and generating labeled output relating to the unlabeled production data. The computer-implemented method also includes inputting the labeled output into a performance predictor. The performance predictor is a meta model of the base model that is trained with another portion of the unlabeled production data, a training set used to train the base model, and a test set portioned from the training set. The computer-implemented method further includes outputting, by the performance predictor, a performance metric relating to the labeled output produced by the trained base model. The performance metric can be any metric capable of measuring the output performance of the base model.

  • Patent number: 11487650
    Abstract: A computer-implemented method, a computer program product, and a computer system for diagnosing anomalies detected by a black-box machine learning model. A computer determines a local variance of a test sample in a test dataset, where the local variance represents uncertainty of a prediction by the black-box machine learning model. The computer initializes optimal compensations for the test sample, where the optimal compensations are optimal perturbations to test sample values of respective components of a multivariate input variable. The computer determines local gradients for the test sample. Based on the local variance and the local gradients, the computer updates the optimal compensations until convergences of the optimal compensations are reached. Using the optimal compensations, the computer diagnoses the anomalies detected by the black-box machine learning model.

    Abstract: A module of capacitor assemblies is provided. To increase the capacitance and efficiency of the module, capacitor assemblies may be stacked. A variety of aspects of the module are controlled in the present invention, including the number of capacitor assemblies, the manner in which the capacitor assemblies are arranged and incorporated into the module, and the manner in which the capacitor assemblies are formed. For example, the anode terminations of each capacitor assembly are electrically connected and the cathode terminations of each capacitor assembly are electrically connected. The capacitance and efficiency of the module can be improved while maintaining the footprint of a single capacitor assembly.
