Non-negative tensor factorization output feature production is closely integrated with a visual post-processing tool, FutureLens, that allows the user to perform in-depth analysis of textual data, facilitating scenario extraction and knowledge discovery....
chapter1:介绍Nonnegative Matrix/Tensor Factorization (NMF, NTF) basic model和其extension。 chapter2:讨论两个非负序列之间的a family of generalized and flexible divergence (散度)和相似度的性质。主要是用作loss function的。比如generalized Kullback-Leibler or I-divergence, Hellinger distance, Jensen-Shannon...

We further argue Nonnegative Matrix Factorization (NMF) is an especially promising linear decomposition method for analysis of activity recorded in calcium imaging in this context. NMF operates under the constraint that every element in the data, and the decomposition, be nonnegative41, as is ...
Our discussion is phrased in the language of nonnegative tensor factorization [5], [9]. We consider real tensors P=[pi1i2⋯in] of format d1×d2×⋯×dn. Throughout this paper we shall assume that n⩾3 and d1,d2,…,dn⩾2. Such a tensor has nonnegative rank at most 2 ...
nonnegative tensor factorizationThis paper describes a method for automatic detection of semantic relations between concept nodes of a networked ontological knowledge base by analyzing matrices of semantic-syntactic valences of words. These matrices are obtained by means of nonnegative factorization of ...
