Hamming Encoder: Mining Discriminative k-mers for Discrete Sequence Classification

no code implementations16 Oct 2023 Junjie Dong, Mudi Jiang, Lianyu Hu, Zengyou He

Existing pattern-based methods measure the discriminative power of each feature individually during the mining process, leading to the result of missing some combinations of features with discriminative power.
