Research Notes

May 15, 2008: I added a short description about K Harmony Means which is a variance of K-Means and X-Means which is a method for finding the number of clusters into My K-Means Clustering Page.

May 14, 2008: A posting on Clustering on Categorical Data might be useful. In relation to that, I have also updated my K-Means page with the K-Modes method which can also be used for clustering categorical data.

May 13, 2008: A note on Similarity Measure is posted today. The measures are useful for performing clustering.

May 09, 2008: A short explanation about the application of the Expectation Maximisation (EM) algorithm to Mixture Modelling was added into My Mixture Modelling page.

May 07, 2008: A short explanation about the Expectation Maximisation (EM) algorithm was posted today. This algorithm is commonly used to find Maximum Likelihood (ML) solution of a probabilistic model.

April 30, 2008: I added a short description about Kernel K-Means to My K-Means Clustering Page.

April 30, 2008: A Note on Support Vector Machine will hopefully give you (and me) a preliminary understanding of the method.

April 28, 2008: A description of a variance of k-means which is the fuzzy c-means method was added into the page of K-Means Clustering.

April 21, 2008: A short description of two clustering validity criteria (Elbow criterion and Gaussian Means criterion) in learning k in k-means were added into the page of K-Means Clustering.

April 15, 2008: I have started a k-means clustering page containing a brief explanation of the clustering method. Please have a look at my K-Means Clustering Page.

April 11, 2008: This page is probably useful for you who have interest in conducting research: TIPS: Mencari Artikel Ilmiah Gratis.

April 08, 2008: Literature review looks simple, but it is not quite. Please have a look at my note on TIPS: Pembuatan Literature Review.

April 03, 2008: I wrote a note on Naive Bayes. Another method for classification based on Bayesian Theory.

March 27, 2008: Based on the discussion we had at indo-dm mailing list, I put a note on kNN Algorithm.

March 19, 2008: I have started a mixture modelling page containing a brief definition of the thing. Please have a look at my Mixture Modelling Page.

March 17, 2008: There will be interns coming from France and will be developing a system on Rule Mining For Relational Database.

March 11, 2008: A girl from Riau asked me about modelling accuracy when using k-means. I then put a note on Akurasi Hasil Pemodelan K-Means. The method explained here is often referred to as Bootstrapped Method.

March 03, 2008: I have started a clustering page containing some clustering methods including k-means, mixture modelling, hierarchical clustering, Self-Organising Map (SOM) and some other related materials. Please have a look at my Mixture Modelling Page.
