Analysis of Models to Estimate Morbidity Rates of Respiratory Diseases Through Deep Learning

Tropical Medicine &International Health, Volume 31, Issue 6, Page 742-753, June 2026.
ABSTRACT Respiratory diseases remain a challenge in Brazil due to socioeconomic inequalities and environmental risks that intensify population vulnerability. This study compared XGBoost with a deep learning model using stacked Gated Recurrent Units (GRU), trained with morbidity data from respiratory diseases and exogenous variables such as per capita ...

A refinement of the Poincaré inequality for Kolmogorov operators on [PDF]

Journal of Inequalities and Applications, 2005
We give a refinement of the Poincare inequality for Kolmogorov operators on . This refinement yields some regularity result of the corresponding semigroups.

Kolmogorov-type inequalities for hypersingular integrals with homogeneous characteristics

Researches in Mathematics
In this article we obtain sharp Kolmogorov-type inequalities that estimate the uniform norm of a hypersingular integral operator $$ D^{w,\Omega}_K f(x): = \int_{C} w(|t|_K) (f(x+t) - f(x))\Omega(t)dt, x\in C, $$ using the uniform norm of the ...

A survey on the classical theory for Kolmogorov equation

, 2019
We present a survey on the regularity theory for classic solutions to subelliptic degenerate Kolmogorov equations. In the last part of this note we present a detailed proof of a Harnack inequality and a strong maximum ...

Minimum Description Length Induction, Bayesianism and Kolmogorov Complexity

, 2000
The relationship between the Bayesian approach and the minimum description length approach is established. We sharpen and clarify the general modeling principles minimum description length (MDL) and minimum message length (MML), abstracted as the ideal ...

THE KOLMOGOROV INEQUALITY FOR THE MAXIMUM OF THE SUM OF RANDOM VARIABLES AND ITS MARTINGALE ANALOGUES

We give a survey of the results related to extensions of the Kolmogorov inequality for the distribution of the absolute value of the maximum of the sum of centered independent random variables to the case of martingales considered at random stopping ...

Harnack inequality and no-arbitrage bounds for self-financing portfolios

We give a direct proof of the Harnack inequality for a class of Kolmogorov operators associated with a linear SDE and we find the explicit expression of the optimal Harnack constant.

A Kolmogorov inequality for weighted U-statistics

In this paper a Kolmogorov probability inequality for weighted U-statistics based on Bernoulli kernels is presented. This inequality which extends the results of [Turner, D.W., Young, D.M., Seaman, J.W., 1995.

Discrete and shift Kolmogorov type inequalities

, 1983
SynopsisThe operators Δhf ≡ f(x) on function spaces and Δxn ≡ xn+1–xn on sequence spaces replace derivatives to yield analogues of the Kolmogorov inequality.
