Point-to-point coupling and imbalance correction in color fringe projection profilometry based on multi-confusion matrix

Measurement science and technology, 2021
Fringe projection profilometry (FPP) has been widely used in three-dimensional (3D) profile measurements for its efficiency and high accuracy. As an offshoot of FPP, color fringe projection profilometry (CFPP) has the advantage of being dynamic, non ...

Confusion Matrix Based Reweighting

2013
This paper introduces a method to rebalance the output of classification algorithms using the corresponding confusion matrices. This is done by modifying the classification output, i.e. reweighting predictions, when they can be interpreted as probabilities.

A LETTER‐DIGIT MATRIX OF AUDITORY CONFUSIONS

British Journal of Psychology, 1973
A matrix is presented of the errors of perception made by 135 men and women listening to three male and three female speakers reading aloud different randomized lists constructed from the letters of the alphabet and the digits 1–9, heard in white noise. Data from a short‐term memory (STM) experiment, using simultaneous visual presentation and immediate

Phonetic confusion matrix based spoken document retrieval

Proceedings of the 23rd annual international ACM SIGIR conference on Research and development in information retrieval, 2000
Combined word-based index and phonetic indexes have been used to improve the performance of spoken document retrieval systems primarily by addressing the out-of-vocabulary retrieval problem. However, a known problem with phonetic recognition is its limited accuracy in comparison with word level recognition.

Complete Control of an Observed Confusion Matrix

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
The error matrix has been adopted as a standard way to report on the thematic accuracy of any remotely sensed data product. A very usual way to perform the thematic accuracy analysis of an error matrix is by means of global indexes (e.g. overall accuracy, Kappa coefficient). But global indices do not allow for a category-wise control.

Range Based Confusion Matrix for Imbalanced Time Series Classification

2020 6th Conference on Data Science and Machine Learning Applications (CDMA), 2020
The recent flood of machine generated data allows for the detection of anomalous behaviors in the corresponding systems, something previously impossible. Consequently, the anomaly detection problem has grown in importance in industrial settings.

Confusion Matrix Visualization

2004
Using the technique of multidimensional scaling the paper demonstrates a method of visualizing a configuration of classes as it is perceived by a classifier. The methodology serves to assist the analysis of multi-class classification problems, where the final result of averaged accuracy or averaged error is not sufficient.

Naval Target Classification Based on the Confusion Matrix

2008 IEEE Aerospace Conference, 2008
In this paper, we propose an algorithm for the classification of naval targets, which is based on the fusion of the class information provided by three imaging sensors: a video camera, an infrared (IR) camera, and an airborne radar operating in spotlight Synthetic Aperture Radar (SAR) mode.

On the confusion matrix in credit scoring and its analytical properties

Communications in Statistics - Theory and Methods, 2019
Confusion Matrix is an important measure to evaluate the accuracy of credit scoring models. However, the literature about Confusion Matrix is limited. The analytical properties of Confusion Matrix are ignored. Moreover, the concept of Confusion Matrix is

Analysis and Presentation of Confusion-Matrix Data

The Journal of the Acoustical Society of America, 1965
As part of the work on an automatic speech recognizer, an approach has been developed to the analysis and presentation of results from confusion tests on potential vocabularies. The method depends on taking the null hypothesis that, if errors occur in a series of responses to a stimulus word.
