kmer2vec: A Novel Method for Comparing DNA Sequences by word2vec Embedding.

The comparison of DNA sequences is of great significance in genomics analysis. Although the traditional multiple sequence alignment (MSA) method is popularly used for evolutionary analysis, optimally aligning sequences becomes computationally intractable when increases due to the intrinsic computational complexity of MSA. Despite numerous -mer alignment-free methods being proposed, the existing -mer alignment-free methods may not truly capture the contextual structures of the sequences.
