Certain aspects of the present disclosure relate to a method for quantizing signals and reconstructing signals, and/or encoding or decoding data for storage or transmission. Points of a signal may be determined as local extrema or points where an absolute rise of the signal is greater than a threshold. The tread and value of the points may be quantized, and certain of the quantizations may be discarded before the quantizations are transmitted. After being received, the signal may be reconstructed from the quantizations using an iterative process.

Embedding entity matching greatly improves computer functioning. Different datasets are matched to a common entity using entity embeddings generated by a machine learning entity embedding model. The entity embeddings are converted to entity similarities, thus revealing the datasets associated with the common entity. Efficient matrix operations further improve computer functioning. Embedding entity matching thus quickly identifies common employee records and user accounts using less hardware resources, less electricity, and less time.
