About the Lab

Professor Sung Bae Jo's research lab specializes in intelligent systems and data-driven decision making, focusing on the integration of soft computing techniques—such as fuzzy logic, neural networks, and genetic algorithms—with machine learning for real-world applications. The lab's main research directions include developing advanced ensemble methods for classification using fuzzy integral-based fusion, applying deep learning and autoencoders to energy demand prediction, and enhancing content-based image retrieval through human emotion and preference modeling. The lab also investigates feature selection and classifier performance in high-dimensional biological data, particularly in cancer diagnosis using microarray data.

Combining multiple neural networks by fuzzy integral for robust classification

IEEE Transactions on Systems Man and Cybernetics

In the area of artificial neural networks, the concept of combining multiple networks has been proposed as a new direction for the development of highly reliable neural network systems. The authors propose a method for multinetwork combination based on the fuzzy integral. This technique nonlinearly combines objective evidence, in the form of a fuzzy membership function, with subjective evaluation of the worth of the individual neural networks with respect to the decision. The experimental result

Machine learning in DNA microarray analysis for cancer classification

Asia-Pacific Bioinformatics Conference

The development of microarray technology has supplied a large volume of data to many fields. In particular, it has been applied to prediction and diagnosis of cancer, so that it expectedly helps us to exactly predict and diagnose cancer. To precisely classify cancer we have to select genes related to cancer because extracted genes from microarray have many noises. In this paper, we attempt to explore many features and classifiers using three benchmark datasets to systematically evaluate the perf

Multiple network fusion using fuzzy logic
Sung‐Bae Cho, J.H. Kim
IEEE Transactions on Neural Networks

Multiplayer feedforward networks trained by minimizing the mean squared error and by using a one of c teaching function yield network outputs that estimate posterior class probabilities. This provides a sound basis for combining the results from multiple networks to get more accurate classification. This paper presents a method for combining multiple networks based on fuzzy logic, especially the fuzzy integral. This method non-linearly combines objective evidence, in the form of a network output

Electric Energy Consumption Prediction by Deep Learning with State Explainable Autoencoder
Jin Young Kim, Sung-Bae Cho
SJR Q1EnergiesOA

As energy demand grows globally, the energy management system (EMS) is becoming increasingly important. Energy prediction is an essential component in the first step to create a management plan in EMS. Conventional energy prediction models focus on prediction performance, but in order to build an efficient system, it is necessary to predict energy demand according to various conditions. In this paper, we propose a method to predict energy demand in various situations using a deep learning model

Incorporating soft computing techniques into a probabilistic intrusion detection system
Sung‐Bae Cho
IEEE Transactions on Systems Man and Cybernetics Part C (Applications and Reviews)

There are a lot of industrial applications that can be solved competitively by hard computing, while still requiring the tolerance for imprecision and uncertainty that can be exploited by soft computing. This paper presents a novel intrusion detection system (IDS) that models normal behaviors with hidden Markov models (HMM) and attempts to detect intrusions by noting significant deviations from the models. Among several soft computing techniques neural network and fuzzy logic are incorporated in

A human-oriented image retrieval system using interactive genetic algorithm

IEEE Transactions on Systems Man and Cybernetics - Part A Systems and Humans

Content-based image retrieval has been actively studied in several fields. This provides more effective management and retrieval of images than the keyword-based approach. However, most of the conventional methods lack the capability to effectively incorporate human intuition and emotion into retrieving images. It is difficult to obtain satisfactory results when the user wants the image that cannot be explicitly described or can be requested only based on impression. In order to solve this probl
