Low-dimensional embedding - A low-dimensional embedding represents an item using relatively few numerical coordinates while aiming to retain relationships useful for a task.
Low frame rate - Low frame rate in speech recognition means processing or emitting acoustic-model representations at fewer time steps per second than a reference configuration.
Low-pass filter - A low-pass filter preserves slowly varying components of a signal while reducing more rapidly varying components.
LU decomposition - LU decomposition factors a matrix into a lower-triangular matrix L and an upper-triangular matrix U, often after row permutations.
Lucas--Kanade method - The Lucas - Kanade method is a gradient-based approach to image alignment.
Lucky imaging - Lucky imaging captures many short exposures, selects those least affected by changing image degradation, aligns them, and combines them into an improved image.
Lusser's law - Lusser's law states that the reliability of a series system equals the product of its component reliabilities when component survival events are...
LZ4 (compression algorithm) - LZ4 is a lossless compression algorithm designed with an emphasis on fast compression and decompression.
LZFSE - LZFSE is a lossless data-compression algorithm that combines Lempel - Ziv-style matching with Finite State Entropy coding.
LZMA - LZMA, short for Lempel - Ziv - Markov chain algorithm, is a lossless compression method that combines dictionary-based matching with probabilistic coding.
LZRW - LZRW refers to a family of lossless compression algorithms associated with Ross Williams, including variants such as LZRW1 and LZRW3.
LZWL - LZWL is a syllable-based variant of Lempel - Ziv - Welch, or LZW, text compression.
