This paper presents how Multistrategy Error Detection and Discovery (MEDD), a student modeling system using machine learning can be applied to the domain of Object Oriented Programming. Java is the language used in learning object oriented programming. MEDD detects the learner’s errors and discovers the misconceptions based on the presence (or absence) of errors.
Conceptual Clustering of Text Clusters
- In Proceedings of FGML Workshop
, 2002
"... Common clustering techniques have the disadvantage that they do not provide intensional descriptions of the clusters obtained. Conceptual Clustering techniques, on the other hand, provide such descriptions, but are known to be rather slow. In this paper, we discuss a way of combining both techniqu ..."

CONCEPTS IN CONCEPTUAL CLUSTERING
"... Although it has a relatively short history, conceptual clustering is an especially active area of research in machine learning. There are a variety of ways in which conceptual patterns (the Al contribution to clustering) play a role in the clustering process. Two distinct conceptual clustering parad ..."

Noise-Tolerant Conceptual Clustering*
"... Fisher (1987a,b) introduced a performance task for conceptual clustering: flexible prediction of arbitrary attribute values, not simply the prediction of a single 'class' attribute. This paper extends earlier analysis by considering the effects of noise and other environmental factors. The ..."

Efficient Feature Selection in Conceptual Clustering
- In Proceedings of the Fourteenth International Conference on Machine Learning
, 1997
"... Feature selection has proven to be a valuable technique in supervised learning for improving predictive accuracy while reducing the number of attributes considered in a task. We investigate the potential for similar benefits in an unsupervised learning task, conceptual clustering. The issues raised ..."

Conceptual Clustering in Information Retrieval
- IEEE Transactions on Systems, Man and Cybernetics
, 1998
"... Clustering is used in information retrieval systems to enhance the efficiency and effectiveness of the retrieval process. Clustering is achieved by partitioning the documents in a collection into classes such that documents that are associated with each other are assigned to the same cluster. This a ..."

Graph-based hierarchical conceptual clustering
- International Journal on Artificial Intelligence Tools
, 2001
"... Hierarchical conceptual clustering has been proven to be a useful data mining technique. Graph-based representation of structural information has been shown to be successful in knowledge discovery. The Subdue substructure discovery system provides the advantages of both approaches. In this paper we ..."

DATA MINING USING CONCEPTUAL CLUSTERING
"... The task of data mining is mainly concerned with the extraction of knowledge from large sets of data. Clustering techniques are usually used to find regular structures in data. Conceptual clustering is one technique that forms concepts out of data incrementally by subdividing groups into subclasses ..."

A New Conceptual Clustering Framework
- MACHINE LEARNING
, 2004
"... We propose a new formulation of the conceptual clustering problem where the goal is to explicitly output a collection of simple and meaningful conjunctions of attributes that define the clusters. The formulation differs from previous approaches since the clusters discovered may overlap and also may ..."
