A Convergent Algorithm for Bi-orthogonal Nonnegative Matrix Tri-Factorization
Andri Mirzal
A convergent algorithm for nonnegative matrix factorization with orthogonality constraints imposed on both factors is proposed in this paper. This factorization concept was first i…
On Estimation of Optimal Process Parameters of the Abrasive Waterjet Machining
Andri Mirzal
This paper is a commentary on the work of Zain et al. (2011a) in which they proposed the use of soft computing techniques, i.e., genetic algorithm (GA) and simulated annealing (SA)…
A Converged Algorithm for Tikhonov Regularized Nonnegative Matrix Factorization with Automatic Regularization Parameters Determination
Andri Mirzal
We present a converged algorithm for Tikhonov regularized nonnegative matrix factorization (NMF). We specially choose this regularization because it is known that Tikhonov regulari…
PID Parameters Optimization by Using Genetic Algorithm
Andri Mirzal, Shinichiro Yoshii, Masashi Furukawa
Time delays are components that make time-lag in systems response. They arise in physical, chemical, biological and economic systems, as well as in the process of measurement and c…
Clustering and Latent Semantic Indexing Aspects of the Nonnegative Matrix Factorization
Andri Mirzal
This paper provides a theoretical support for clustering aspect of the nonnegative matrix factorization (NMF). By utilizing the Karush-Kuhn-Tucker optimality conditions, we show th…
Design and Implementation of a Simple Web Search Engine
Andri Mirzal
We present a simple web search engine for indexing and searching html documents using python programming language. Because python is well known for its simple syntax and strong sup…
