7:00 – 8:00 Research

• Add a frame sampling text field. Default of 10? Zero = sample. Hitting the limit = reset sampleIncrement to zero. Done. Found a bug that screwed up the average center calculation:

  globalCenter.add(arv);

  Should have been

  globalCenter = globalCenter.add(arv);

• Set up page that shows the 5th, 50th and 95th percentiles for each statement’s population sample. Put in a new tab.
• Add a tab that shows the 5th/95th – the 50th? That could sum to a nice chart
• The above two items will need a Collection of Percentiles for all agents positions at a step across all dimensions. Tomorrow

9:00 – 5:00BRC

• Try using MySQL instead of postgres. Nope, pointless
• Maybe save as CSV? Changed the toString() method to be a toWriter(Writer writer) method. Now toString calls that with a StringWriter and toCSV calls it with a BufferedWriter()
• Use “output folder” as database/schema. Then session becomes the table. Will need to check that the db/schema exists and create as needed
• Output the list of items with clusterId(+1) for Bob
• Reduce the size of the matrix by eliminating all non-cluster members? Can certainly do this in the display of the cluster matrix.
• Left with the NMF app cooking for a 4-level deep set of matrices. Hmm. Blew up with NaNs. Test cases work fine. I’ll try scaling up slowly
