The goal of zero-knowledge watermark detection is to allow a prover to soundly convince a verifier of the presence of a watermark in certain stego-data without revealing any infor...
Abstract. We propose a new unsupervised training method for acquiring probability models that accurately segment Chinese character sequences into words. By constructing a core lexi...
This paper describes an unsupervised algorithm for segmenting categorical time series. The algorithm first collects statistics about the frequency and boundary entropy of ngrams, t...
