Latest Patents

Zappella's latest patents include groundbreaking techniques for concept shift detection and correction using probabilistic models and learned feature representations. This patent describes a method where a Gaussian process model is trained using representations generated by a primary machine learning model for existing training data elements. For new data elements, these representations can be used as input for the Gaussian process model to generate predictive distributions. If the true targets for the new data elements are not sufficiently likely according to the predictive distributions, it indicates a likely concept shift, prompting the purging of existing data elements from the training memory before further retraining of the primary model.

Another notable patent focuses on resource-efficient techniques for repeated hyper-parameter optimization. This involves evaluating a particular hyper-parameter combination recommended for a first task and including it in a collection of candidate hyper-parameter combinations for a second task. The process includes conducting hyper-parameter analysis iterations and pruning HPCs based on their results, ultimately identifying a recommended HPC for the second task.
