Latest Patents

Hassan Lahdili holds a patent for his invention titled "Sparse Data Compression." This invention relates to the compression of sparse data sets that contain sequences of data values and their corresponding position information. The position information is represented in the form of position indices that define the active positions of the data values within a sparse vector of length N. The invention encodes the position information into the data values by adjusting one or more of the data values within a pre-defined tolerance range. This adjustment ensures that a pre-defined mapping function of the data values and their positions is close to a target value. In one embodiment, the mapping function utilizes a subset of N filler values, which are used to fill empty positions in the input sparse data vector. At the decoder, the correct data positions are identified by searching through possible subsets of filler values.
