Balancing between over-weighting and under-weighting in supervised term weighting [PDF]
Information Processing & Management, 2017 Show the importance of the trade-off between over-weighting and under-weighting.Propose a revision of add-one smoothing on delta smoothed idf (dsidf).Present three regularization techniques to reduce over-weighting.Propose a new supervised term weighting scheme, regularized entropy (re).

Short-term variability in body weight predicts long-term weight gain [PDF]
The American Journal of Clinical Nutrition, 2015 Body weight in lower animals and humans is highly stable despite a very large flux in energy intake and expenditure over time. Conversely, the existence of higher-than-average variability in weight may indicate a disruption in the mechanisms responsible for homeostatic weight regulation.In a sample chosen for weight-gain proneness, we evaluated whether

Weighted Choquard Equation Perturbed with Weighted Nonlocal Term [PDF]
Differential Equations and Dynamical Systems, 2021 AbstractWe investigate the following problem $$\begin{aligned} -\mathrm{div}(v(x)|\nabla u|^{m-2}\nabla u)+V(x)|u|^{m-2}u= \left( |x|^{-\theta }*\frac{|u|^{b}}{|x|^{\alpha }}\right) \frac{|u|^{b-2}}{|x|^{\alpha }}u+\lambda \left( |x|^{-\gamma }*\frac{|u|^{c}}{|x|^{\beta }}\right) \frac{|u|^{c-2}}{|x|^{\beta }}u \quad \text { in }{\mathbb {R}}^{N}, \end{
