k and d are the only required parameters. For others, value 0 means default.
Member documentation
- k – segment size : constraint: 0 < k : Reasonable range [16, 2048+]
- d – dmer size : constraint: 0 < d <= k : Reasonable range [6, 16]
- steps – Number of steps : Only used for optimization : 0 means default (40) : Higher means more parameters checked
- nbThreads – number of threads : constraint: 0 < nbThreads : 1 means single-threaded : Only used for optimization : Ignored if ZSTD_MULTITHREAD is not defined.
- splitPoint – percentage of samples used for training: Only used for optimization: the first nbSamples * splitPoint samples will be used to training, the last nbSamples * (1 - splitPoint) samples will be used for testing, 0 means default (1.0), 1.0 when all samples are used for both training and testing.
