My PhD thesis

I did my PhD in the 1990s in artificial intelligence. I focused on artificial neural networks, in particular the Sparse Distributed Memory (SDM) and the Cerebellar Model Articulation Controller (CMAC), investigating their capabilities and capacities.  This included their ability to store and recognize sequences. I also looked at how to combine the CMAC with a robot learning system called PURR-PUSS.  In a simple control problem I was able to show how CMAC could learn from PURR-PUSS, providing smother control.

I had a back up on floppy disks and although I was able to get the data off the disks, I failed to find a copy of Norton Backup that could read the 30 year old files. So I resorted to scanning the book and using OCR to convert it into text.

You can download a PDF of my thesis titled Investigations into the capabilities of the SDM and combining CMAC with PURR-PUSS. The diagrams are the scans from the dot matrix printout I did all those years ago.

I completed my PhD at the University of Canterbury, supervised by John Andreae who continues to contribute to the field in his 90s. My examiners were Ian Witten and an American academic that I can’t remember.

After creating a digital copy of my thesis I discovered that the university also has a copy here. This goes to show that just because you’ve got a PhD, it doesn’t mean you’re that bright.
