A Good Evaluation Based on Confusion Matrix for Lung Diseases Classification using Convolutional Neural Networks

open access: yesAdvance Sustainable Science, Engineering and Technology, 2023
CNN has been widely used to detect a pattern with image classification. This study used CNN to perform a classification analysis of lung abnormality detection on chest X-ray images. The dataset consists of 5,732 2D images with dimensions of 200 x 200 x 1

Fair evaluation of classifier predictive performance based on binary confusion matrix

open access: yesComputational statistics (Zeitschrift), 2022
Evaluating the ability of a classifier to make predictions on unseen data and increasing it by tweaking the learning algorithm are two of the main reasons motivating the evaluation of classifier predictive performance.

Information Theory’s failure in neuroscience: on the limitations of cybernetics [PDF]

open access: yes, 2014
In Cybernetics (1961 Edition), Professor Norbert Wiener noted that “The role of information and the technique of measuring and transmitting information constitute a whole discipline for the engineer, for the neuroscientist, for the psychologist, and for ...

Relative Confusion Matrix: Efficient Comparison of Decision Models

open access: yesInternational Conference on Information Visualisation, 2022
Current machine learning and deep learning approaches are cutting-edge methods for solving classification tasks. Comparing the performances of classification models has become a prominent task since the outbreak of these techniques.

On non-abelian generalisation of Born-Infeld action in string theory [PDF]

open access: yes, 1997
We show that the part of the tree-level open string effective action for the non-abelian vector field which depends on the field strength but not on its covariant derivatives, is given by the symmetrised trace of the direct non-abelian generalisation of ...

Unconfused Ultraconservative Multiclass Algorithms [PDF]

open access: yes, 2013
We tackle the problem of learning linear classifiers from noisy datasets in a multiclass setting. The two-class version of this problem was studied a few years ago by, e.g. Bylander (1994) and Blum et al.

The impact of class imbalance in classification performance metrics based on the binary confusion matrix

open access: yesPattern Recognition, 2019
A major issue in the classification of class imbalanced datasets involves the determination of the most suitable performance metrics to be used. In previous work using several examples, it has been shown that imbalance can exert a major impact on the ...

A Comparison of Model-Assisted Estimators to Infer Land Cover/Use Class Area Using Satellite Imagery

open access: yesRemote Sensing, 2014
Remote sensing provides timely, economic, and objective data over a large area and has become the main data source for land cover/use area estimation. However, the classification results cannot be directly used to calculate the area of a given land cover/
