Journal ArticleDOI
An effective method for classification with missing values
TL;DR: The proposed method, Model based Missing value Imputation using Correlation (MMIC), can effectively impute both categorical and numeric data and outperforms various existing methods for handling missing data in classification.
Journal ArticleDOI
An Effective Recursive Technique for Multi-Class Classification and Regression for Imbalanced Data
Tahira Alam,Chowdhury Farhan Ahmed,Sabit Anwar Zahin,Muhammad Asif Hossain Khan,Maliha Tashfia Islam +4 more
TL;DR: Experimental results demonstrate that the proposed recursive technique is effective and improves the performance when compared to existing methods for classification and regression with imbalanced distribution.
Book ChapterDOI
An Effective Ensemble Method for Multi-class Classification and Regression for Imbalanced Data
Tahira Alam,Chowdhury Farhan Ahmed,Sabit Anwar Zahin,Muhammad Asif Hossain Khan,Maliha Tashfia Islam +4 more
TL;DR: Extensive performance analyses show that the proposed approach achieves high performance in multi-class classification on class imbalance data and regression analysis on skewed or imbalance data, and experimental results show that this method outperforms various existing methods for imbalance classification and regression.
Proceedings ArticleDOI
A Study on Deep Reinforcement Learning Based Traffic Signal Control for Mitigating Traffic Congestion
TL;DR: In this article, a deep Q-network (DQN) method based on different traffic flow information was proposed to control the traffic signal dynamically. But deep RL has not employed the control of the traffic signals by observing traffic flow in any busy road.
Book ChapterDOI
Discovering Correlation in Frequent Subgraphs
Fariha Moomtaheen Upoma,Salsabil Ahmed Khan,Chowdhury Farhan Ahmed,Tahira Alam,Sabit Anwar Zahin,Carson K. Leung +5 more
TL;DR: Two measures are proposed that help to discover correlation among frequent subgraphs within large graph databases, based on the observation that elements in graphs exhibit the tendency to occur both connected and disconnected.
