Jump to: navigation, search


  • Word pairs visualisation.
  • Hopfield visualisation.


  • revising my knowledge of PLN from the book.
  • Refactoring Ubigrapher class
  • Discovered that Ubigraph server stall occurs less frequently if you turn of the layout lagorithm until after all atoms added.


  • Investigating best way to make a series of visual demos for AGI09 using Ubigraph connection.
  • Got side track with the fact the server stalls occasionally. Unable to work out why, but it is more frequent with large graphs (although doesn't happen with the example graphs??)
  • Decided to try making a small test example.
