Title: Innovations of Rajeev Ranjan

Introduction

Rajeev Ranjan is a notable inventor based in Seattle, WA. He has made significant contributions to the field of biometric identification systems. With a total of six patents to his name, Ranjan's work focuses on enhancing the efficiency and effectiveness of biometric recognition technologies.

Latest Patents

One of his latest patents is a "System to determine compact representation of data." This invention involves acquiring an image of a user during enrollment in a biometric identification system. The system processes this image to determine a compact representation (CR) that can be stored for later comparison. Notably, the image itself is not stored, ensuring user privacy. The CR is generated using a machine learning system that employs a variational autoencoder, which is trained to produce the CR with a specific loss function. This approach allows for more computationally efficient training and recognition comparisons.

Another significant patent is the "System for single image multimodal biometric recognition." This system acquires a multimodal image and is trained to determine three types of embeddings: a first embedding for features in a first modality, an intersection embedding for shared features, and an XOR embedding for unique features. Once trained, the system can process a multimodal query image to determine query embedding data, which can then be compared with previously enrolled data to assert identity.
