  1. AI class by Dr. Peter Molnar Presented by Omar ElTayeby & Jonathan Lutu Midterm Project (Bioinformatics) Dataset Preprocess Clustering techniques Visualized Results Weka’s report

  2. Data set GROMOS format: is a general-purpose molecular dynamics computer simulation package for the study of biomolecular systems. It also incorporates its own force field covering proteins, nucleotides, sugars etc. and can be applied to chemical and physical systems ranging from glasses and liquid crystals, to polymers and crystals and solutions of biomolecules.

  3. GROMOS fields • Molecule name • Atom name • Index • X-position • Y-position • Z-position • Velocity in X • Velocity in Y • Velocity in Z

  4. Preprocessing

  5. Visualized Results

  6. The class attribute MolName is ignored using the ignore attribute panel in order to allow later classes to cluster evaluation

  7. Cobweb Clustered Instances   5        1 (  1%)   6        1 (  1%)  10        3 (  2%)  26        2 (  1%)  32        1 (  1%) 192        2 (  1%) 193        2 (  1%) 194        3 (  2%) 198        2 (  1%) 209        3 (  2%) 210        1 (  1%) 211        3 (  2%) 212        1 (  1%) 213        3 (  2%) 218        1 (  1%) 220       51 ( 26%) Cobweb generates hierarchical clustering, where clusters are described probabilistically. Time taken to build model (percentage split) : 1.08 sec Model and evaluation on training set Number of merges: 264 Number of splits: 242 Number of clusters: 159

  8. DBscan DBSCAN (for density-based spatial clustering of applications with noise)    it finds a number of clusters starting from the estimated density distribution of corresponding nodes. OPTICS is generalized version of it Epsilon: 0.9; minimum Points: 6 Distance-type: weka.clusterers.forOPTICSAndDBScan.DataObjects.EuclideanDataObject Number of generated clusters: 1 Elapsed time: .28 Time taken to build model (percentage split) : 0.27 seconds Clustered Instances 0      200 (100%)

  9. EM Expectation Maximization is an iterative method for finding maximum likelihood (maximum a posteriori (MAP)) estimates of parameters in statistical models, where the model depends on unobserved latent variables.
