On sharpness of error bounds for multivariate neural network approximation [PDF]

open access: yesRicerche di Matematica, 2020
AbstractSingle hidden layer feedforward neural networks can represent multivariate functions that are sums of ridge functions. These ridge functions are defined via an activation function and customizable weights. The paper deals with best non-linear approximation by such sums of ridge functions.

Highway Traffic Flow Prediction Algorithm Based on Multiscale Transformation and Convolutional Networks

open access: yesJournal of Control Science and Engineering, 2022
In order to solve the problem that the traditional long-term high-speed traffic forecasting algorithm is affected by the approximation ability of the function and easy to fall into the local mass value, we wrote a multivariate-based highway traffic ...

Improved Uncertainty Quantification for Neural Networks With Bayesian Last Layer

open access: yesIEEE Access, 2023
Uncertainty quantification is an important task in machine learning - a task in which standard neural networks (NNs) have traditionally not excelled. This can be a limitation for safety-critical applications, where uncertainty-aware methods like Gaussian

A Neural Network Approximation Based on a Parametric Sigmoidal Function

open access: yesMathematics, 2019
It is well known that feed-forward neural networks can be used for approximation to functions based on an appropriate activation function. In this paper, employing a new sigmoidal function with a parameter for an activation function, we consider a ...

Why and When Can Deep -- but Not Shallow -- Networks Avoid the Curse of Dimensionality: a Review [PDF]

open access: yes, 2017
The paper characterizes classes of functions for which deep learning can be exponentially better than shallow learning. Deep convolutional networks are a special case of these conditions, though weight sharing is not the main reason for their exponential

Machine Learning Alternatives to Response Surface Models

open access: yesMathematics, 2023
In the Design of Experiments, we seek to relate response variables to explanatory factors. Response Surface methodology (RSM) approximates the relation between output variables and a polynomial transform of the explanatory variables using a linear model.

A Coverage Study of the CMSSM Based on ATLAS Sensitivity Using Fast Neural Networks Techniques [PDF]

open access: yes, 2011
We assess the coverage properties of confidence and credible intervals on the CMSSM parameter space inferred from a Bayesian posterior and the profile likelihood based on an ATLAS sensitivity study.

A Deep Neural Network Algorithm for Linear-Quadratic Portfolio Optimization With MGARCH and Small Transaction Costs

open access: yesIEEE Access, 2023
We analyze a fixed-point algorithm for reinforcement learning (RL) of optimal portfolio mean-variance preferences in the setting of multivariate generalized autoregressive conditional-heteroskedasticity (MGARCH) with a small penalty on trading.

Punzi-loss:

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
We present the novel implementation of a non-differentiable metric approximation and a corresponding loss-scheduling aimed at the search for new particles of unknown mass in high energy physics experiments.
