Convolutional Neural Networks Exploiting Attributes of Biological Neurons

no code implementations14 Nov 2023 Neeraj Kumar Singh, Nikhil R. Pal

In this era of artificial intelligence, deep neural networks like Convolutional Neural Networks (CNNs) have emerged as front-runners, often surpassing human capabilities.

Group-Feature (Sensor) Selection With Controlled Redundancy Using Neural Networks

no code implementations31 Oct 2023 Aytijhya Saha, Nikhil R. Pal

In this paper, we present a novel embedded feature selection method based on a Multi-layer Perceptron (MLP) network and generalize it for group-feature or sensor selection problems, which can control the level of redundancy among the selected features or groups.

Feature selection simultaneously preserving both class and cluster structures

no code implementations8 Jul 2023 Suchismita Das, Nikhil R. Pal

When a data set has significant differences in its class and cluster structure, selecting features aiming only at the discrimination of classes would lead to poor clustering performance, and similarly, feature selection aiming only at preserving cluster structures would lead to poor classification performance.

Understanding the classes better with class-specific and rule-specific feature selection, and redundancy control in a fuzzy rule based framework

no code implementations2 Aug 2022 Suchismita Das, Nikhil R. Pal

Unlike traditional feature selection methods, the class-specific feature selection methods select an optimal feature subset for each class.

Nonlinear Dimensionality Reduction for Data Visualization: An Unsupervised Fuzzy Rule-based Approach

no code implementations8 Apr 2020 Suchismita Das, Nikhil R. Pal

It considers the following important issues relevant to dimensionality reduction-based data visualization: (i) preservation of neighborhood relationships, (ii) handling data on a non-linear manifold, (iii) the capability of predicting projections for new test data points, (iv) interpretability of the system, and (v) the ability to reject test points if required.
