Latest Patents

One of his latest patents is titled "System and method for automatic subcharacter unit and lexicon generation." This technology enhances handwriting recognition systems by utilizing a processing unit, handwriting input device, and memory. The invention details how a segmentation unit generates feature vectors, which are subsequently clustered by a subcharacter generation unit. The lexicon unit constructs lexical graphs, while the modeling unit generates Hidden Markov Models for the identified feature vectors. This iterative process helps refine subcharacter units, ultimately improving the accuracy of handwriting recognition systems.

Another notable patent by Lee is the "Rapid tree-based method for vector quantization." This method revolutionizes binary tree-based vector quantization (VQ) by using simple comparisons and pre-assigned thresholds to make decisions at each node of the tree. Conventional centroid distance training techniques are applied for establishing code-book indices, leading to a more efficient processing speed while maintaining accuracy comparable to traditional methods. This invention contributes significantly to the fields of data processing and machine learning.
