  • Publication number: 20250200135
    Abstract: Provided are systems, methods, and apparatuses of data processing for machine learning. In one or more examples, the systems, devices, and methods include determining priority values for elements of a weight matrix based on a gradient of a loss function of an AI model and the weight matrix; determining an index value based on a number of elements in the weight importance matrix and a sparsity ratio; determining a threshold based on sorting the elements of the weight importance matrix in sequential order and determining a value of an element of the sorted weight importance matrix based on using the index value as an index of the sorted weight importance matrix; determining a pruned weights matrix based on the threshold; and processing a query using an updated AI model, the updated AI model being based on the pruned weights matrix being implemented in the AI model.

  • Publication number: 20250190394
    Abstract: Provided are systems, methods, and apparatuses for artificial intelligence query processing by processing-near-memory storage. In one or more examples, the systems, devices, and methods include receiving, at a first processing-near-memory (PNM) storage device, data and processing, at the first PNM storage device, first values from the data with transposed query values from the data. In one or more examples, the systems, devices, and methods include determining, at the first PNM storage device, a probability distribution of a result of the processing and generating, at the first PNM storage device, an activation value based on the probability distribution, the activation value indicating a correlation between units of text in a query associated with the data.
