Confusion Matrix Analysis for Form Perception

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1967
The Constant-Ratio Rule (CRR), an empirical technique for analysis of confusion matrices, was developed for use in predicting intelligibility of speech syllables. This study investigated the validity of the rule when applied to the data from experiments on visual form perception.

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.

Discountings of a Belief Function Using a Confusion Matrix

2010 22nd IEEE International Conference on Tools with Artificial Intelligence, 2010
In this paper, we present an analysis of different approaches relative to the correction of belief functions based on the results given by a confusion matrix. Three different mechanisms based on discountings are detailed. These methods have the objective to assess the discounting rates to be assigned to a source of information.

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

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.

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.

The Matrix of Confusion—a Classification of Robot Movement

Proceedings of the Institution of Mechanical Engineers, Part B: Journal of Engineering Manufacture, 1996
The human-machine interface for robots has received only limited attention as robots have developed. Most research has focused on the design of teach pendants, hand-held devices for programming and manual motion control. Results from these studies have been generally inconclusive as to the best control design for teach pendants.

A confusion matrix for the study of taste perception.

Perception & psychophysics, 2000
Taste stimulus identification was studied in order to more thoroughly examine human taste perception. Ten replicates of an array of 10 taste stimuli--NaCl, KCl, Na glutamate, quinine. HCl, citric acid, sucrose, aspartame, and NaCl-sucrose, acid-sucrose, and quinine-sucrose mixtures--were presented to normal subjects for identification from a list of ...

On the Confusion Matrix

Configurations
ABSTRACT: Confusion matrices are graphical objects used in machine learning to demonstrate the efficacy of models. They frequently take the form of brightly colored figures adorning scientific reports and technical documents. Guiding readers of these texts through an interpretation of models with their special affordances, such as diagonal lines that ...

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.
