Analysis of gene expression data provides an objective and efficient technique for sub-classification of leukemia. The purpose of the present study was to design a committee neural networks based classification systems to subcategorize leukemia gene expression data. In the study, a binary classification system was considered to differentiate acute lymphoblastic leukemia from acute myeloid leuke...

Generally, assessment of fasting glucose is recommended as screening and monitoring for diabetes (ADA/APA consensus, 2004) although an Oral Glucose Tolerance Test (OGTT) remains the gold standard (Expert Committee on the Diagnosis and Classification of Diabetes Mellitus, 2003). HbA1c is accepted as a useful index of mean blood glucose levels in the treatment of patients with diabetes but was no...

A novel face recognition method based on multi-features using a neural networks committee (NNC) machine is proposed in this paper. The committee consists of several independent neural networks trained by different image blocks of the original images in different feature domains. The final classification results represent a combined response of the individual networks. Then, we use the designed ...

Committee decision making is examined in this study focusing on the role assigned to the committee members. In particular, we are concerned about the comparison between committee performance under specialization and non-specialization of the decision makers. JEL Classification number: D81, D71

Concept drift occurs when a target concept changes over time. I present a new method for learning shifting target concepts during concept drift. The method, called Concept Drift Committee (CDC), uses a weighted committee of hypotheses that votes on the current classification. When a committee member’s voting record drops below a minimal threshold, the member is forced to retire. A new committee...
