Multi-channel non-negative matrix factorization (MNMF) is a multi-channel extension of NMF and often outperforms NMF because it can deal with spatial and spectral information simultaneously. On the other hand, MNMF has a larger number of parameters and its performance heavily depends on the initial values. MNMF factorizes an observation matrix into four matrices: spatial correlation, basis, clu...

It is well known that, for a linear program (LP) with constraint matrix A ∈ Rm×n, the Alternating Direction Method of Multiplier converges globally and linearly at a rate O((‖A‖F +mn) log(1/ )). However, such a rate is related to the problem dimension and the algorithm exhibits a slow and fluctuating “tail convergence” in practice. In this paper, we propose a new variable splitting method of LP...

Massive image collections are increasingly available on the Web. These collections often incorporate complementary non-visual data such as text descriptions, comments, user ratings and tags. These additional data modalities may provide a semantic complement to the image visual content, which could improve the performance of different image content analysis tasks. This paper presents a novel met...

This work proposes a new algorithm for automated and simultaneous phenotyping of multiple co–occurring medical conditions, also referred as comorbidities, using clinical notes from the electronic health records (EHRs). A basic latent factor estimation technique of non-negative matrix factorization (NMF) is augmented with domain specific constraints to obtain sparse latent factors that are ancho...

We address the issue of source separation in a particular informed configuration where both the sources and the mixtures are assumed to be known during a so-called encoding stage. This knowledge enables the computation of a side information which ought to be small enough to be watermarked in the mixtures. At the decoding stage, the sources are no longer assumed to be known, only the mixtures an...

The Covid-19 pandemic has brought changes to society in several aspects of people’s everyday life. One them is the short and long-term impact on mobility during early stages post-pandemic period. This paper aims study effects UG engineering students for selection Engineering Colleges pre post-COVID-19 era. was done at Techno College Banipur, WB, India. work utilized GIS compare spatial distribu...

The world is facing a poverty crisis. Despite the great achievements that have been made in alleviation over past two decades, extent of countries along Belt and Road still high. Successful reduction these crucial to meeting 2030 SDGs. Improving governance eradicate shortcoming needs be addressed urgently pathways Road. In this study, Standard Deviational Ellipse method was used study spatial t...

An economic environment is a feedback system, where the dynamics of aggregate variables depend on individual expectations and vice versa. The type of feedback mechanism is crucial for the aggregate outcome. Experiments with human subjects (Heemeijer, Hommes, Sonnemans, and Tuinstra, 2009) have shown that price converges to the fundamental level in a negative feedback environment but fails to do...

A feedback control algorithm for Variable Message Sign (VMS) of Urban Network is proposed. And traffic signal coordination with VMS is explicitly considered in the proposed VMS control algorithm. It is generally true that feedback control approach requires low computational effort and is less sensitive to model’s inaccuracy and disturbance uncertainties. Several issues in VMS control are raised...
