This invention describes a method for recognizing data, such as images or audio, by processing it through a series of steps. First, it extracts key characteristics from the raw data. Then, it groups similar parts of these characteristics together. Finally, it combines these grouped parts into a unique digital signature, called an embedding vector. This unique signature can then be used to identify the input data, for example, by matching it to a specific registered user.
Why it matters: Filed before the widespread maturation of deep learning frameworks and pre-trained models. The ability to generate highly discriminative embedding vectors for user recognition has advanced significantly, making such systems more accurate and efficient to build today.
AI gives you a few directions you could take this. Pick one, and we check whether your version is different enough to patent, then write the filing.
