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…
On the clustering aspect of nonnegative matrix factorization
Andri Mirzal, Masashi Furukawa
This paper provides a theoretical explanation on the clustering aspect of nonnegative matrix factorization (NMF). We prove that even without imposing orthogonality nor sparsity con…
Node-Context Network Clustering using PARAFAC Tensor Decomposition
Andri Mirzal, Masashi Furukawa
We describe a clustering method for labeled link network (semantic graph) that can be used to group important nodes (highly connected nodes) with their relevant link's labels by us…
Eigenvectors for clustering: Unipartite, bipartite, and directed graph cases
Andri Mirzal, Masashi Furukawa
This paper presents a concise tutorial on spectral clustering for broad spectrum graphs which include unipartite (undirected) graph, bipartite graph, and directed graph. We show ho…
A Method for Accelerating the HITS Algorithm
Andri Mirzal, Masashi Furukawa
We present a new method to accelerate the HITS algorithm by exploiting hyperlink structure of the web graph. The proposed algorithm extends the idea of authority and hub scores fro…
