On the continued Erlang loss function [PDF]

open access: yes, 1986
We prove two fundamental results in teletraffic theory. The first is the frequently conjectured convexity of the analytic continuation B(x, a) of the classical Erlang loss function as a function of x, x 0. The second is the uniqueness of the solution of

Generalization of Cross-Entropy Loss Function for Image Classification

open access: yesMohyla Mathematical Journal, 2021
Classification task is one of the most common tasks in machine learning. This supervised learning problem consists in assigning each input to one of a finite number of discrete categories.

Are Analysts' Loss Functions Asymmetric? [PDF]

open access: yesJournal of Forecasting, 2006
ABSTRACTDespite displaying a statistically significant optimism bias, analysts' earnings forecasts are an important input to investors’ valuation models. Understanding the possible reasons for any bias is important if information is to be extracted from earnings forecasts and used optimally by investors. Extant research into the shape of analysts' loss

Application of Weighted Cross-Entropy Loss Function in Intrusion Detection

open access: yesJournal of Computer and Communications, 2021
The deep learning model is overfitted and the accuracy of the test set is reduced when the deep learning model is trained in the network intrusion detection parameters, due to the traditional loss function convergence problem.

Deep Learning Techniques for Vehicle Detection and Classification from Images/Videos: A Survey

open access: yesSensors, 2023
Detecting and classifying vehicles as objects from images and videos is challenging in appearance-based representation, yet plays a significant role in the substantial real-time applications of Intelligent Transportation Systems (ITSs).

Retail commodity detection method based on location learnable visual center mechanism

open access: yes物联网学报, 2023
To address the problem of low detection accuracy caused by the difficulty in effectively capturing significant and diversified feature information for packaging deformation and overlap products, a location learnable visual center (LLVC) mechanism was ...

Fitting Jump Models [PDF]

open access: yes, 2018
We describe a new framework for fitting jump models to a sequence of data. The key idea is to alternate between minimizing a loss function to fit multiple model parameters, and minimizing a discrete loss function to determine which set of model ...

Loss Functions for Loss Estimation

open access: yesThe Annals of Statistics, 1988
Let X be a random variable with distribution \(P_{\theta}\), where \(\theta\in \Theta\), and d(X) a decision for \(\theta\) with loss W(\(\theta\),d(X)). A class of loss functions combining the decision error W(\(\theta\),d(X)) and the error in estimating W(\(\theta\),d(X)) by h(X) is introduced. Under these loss functions the Bayes procedure \((d_ B(X)
