The restricted Boltzmann machine (RBM) has been used as building blocks for many successful deep learning models, e.g., deep belief networks (DBN) and deep Boltzmann machine (DBM) etc. The training of RBM can be extremely slow in pathological regions. The second order optimization methods, such as quasi-Newton methods, were proposed ...

The classical bag-of-word models for information retrieval (IR) fail to capture contextual associations between words. In this article, we propose to investigate pure high-order dependence among a number of words forming an unseparable semantic entity, that is, the high-order dependence that cannot be reduced to the random coincidence of lower-order ...
Keywords: information geometry, pure high-order dependence, Word association, text classification, text retrieval

The road network design problem is to optimize the road network by selecting paths to improve or adding paths in the existing road network, under certain constraints, e.g., the weighted sum of modifying costs. Since its multi-objective nature, the road network design problem is often challenging for designers. Empirically, the ...

Conceptual entanglement is a crucial phenomenon in quantum cognition because it implies that classical probabilities cannot model non-compositional conceptual phenomena. While several psychological experiments have been developed to test conceptual entanglement, this has not been explored in the context of Natural Language Processing. In this paper, we apply the hypothesis ...

Estimating the probability of relevance for a document is fundamental in information retrieval. From a theoretical point of view, risk exists in the estimation process, in the sense that the estimated probabilities may not be the actual ones precisely. The estimation risk is often considered to be dependent on the ...
Keywords: estimation, language modeling, probability of relevance, ranking-independent risk, risk management

The classical bag-of-word models fail to capture contextual associations between words. We propose to investigate the "high-order pure dependence" among a number of words forming a semantic entity, i.e., the high-order dependence that cannot be reduced to the random coincidence of lower-order dependence. We believe that identifying these high-order pure ...
Keywords: high-order pure dependence, information geometry, log likelihood ratio test, query expansion, word association, language model

Query expansion, while generally effective in improving retrieval performance, may lead to the query-drift problem. Following the recent development of applying Quantum Mechanics (QM) to IR, we investigate the problem from a novel theoretical perspective inspired by photon polarization (a key QM experiment).

Quantum theory QT has recently been employed to advance the theory of information retrieval IR. A typical method, namely the Quantum Probability Ranking Principle QPRP, was proposed to re-rank top retrieved documents by considering the inter-dependencies between documents through the "quantum interference". In this paper, we attempt to explore another ...
