Grammatical inference (GI) of context free languages (CFG) is an actively researched area of computer science. There are some algorithm, based on different approaches, to induce CFGs and we are going to test and compare the standard CFG generation methods. The goal of the comparison is to develop a more efficient CFG induction method. In order to super the testing and comparison of algorithm, a GI...
The pre-clustering is an efficient data reduction method in the case of large data sets. In the pre-clustering process, an important aspect is to provide a good intra-cluster similarity. Most of the traditional methods do not consider this aspect and they generate weak clusters. The paper presents some algorithms to optimize the key parameters (like branching factor, quality threshold and selection...
