Latest Patents

One of Ruoqian Liu's latest patents is titled "Leveraging JPEG discrete cosine transform coefficients in neural networks." This innovative system classifies compressed images and predicts likelihood values associated with them. It partially decompresses JPEG image data to obtain blocks of discrete cosine transform (DCT) coefficients that represent the image. The system applies various transform functions to these blocks, allowing them to be input together into a neural network for analysis. This method is less computationally intensive than using raw image data as input.

Another notable patent is "Generating compressed representation neural networks having high degree of accuracy." This invention involves machine learning models that utilize fewer parameters than typically required. The model is trained using an initial parameter vector, modified during the training phase in a subspace around the initial vector. The trained model can be stored or transmitted using seed values, allowing for efficient uncompression. This compressed representation can be applied in various fields, including object recognition, natural language processing, and more.
