Title: Innovations by Luca Melis

Introduction

Luca Melis is an accomplished inventor based in New York, NY, with a notable portfolio of four patents. His work primarily focuses on advanced algorithms and systems that enhance data processing and anomaly detection in computing environments.

Latest Patents

One of his latest patents is titled "Generating relaxed synthetic data using adaptive projection." This innovative algorithm is designed to release answers to a vast number of statistical queries while maintaining differential privacy. It effectively answers queries on a private dataset through simple perturbation and seeks to create a synthetic dataset that closely aligns with the noisy answers. The algorithm employs a continuous relaxation of the synthetic dataset domain, making the projection loss differentiable and enabling the use of efficient machine learning optimization techniques. By judiciously utilizing a privacy budget, the algorithm adaptively identifies queries with high error and iteratively refines the projection.

Another significant patent by Melis is "Detecting anomalous events from categorical data using autoencoders." This invention provides systems, devices, and methods for identifying anomalous events from categorical data. The system receives a dataset related to actions within a computing environment, which includes categorical data indicative of anomalous activity. It trains an autoencoder to reconstruct approximations of requests based on the dataset, utilizing beta divergence and maximum mean discrepancy divergence. The trained system can then evaluate requests to determine if they indicate anomalous data based on a calculated normalcy score.
