Early Results Comparing Evolved and Target Curves
on the CAM-Brain Machine (CBM) April 2000
The images below show how the CAM-Brain Machine (CBM) evolves a curve (red line) to follow as closely as possible a target curve (orange line). The target curves were generated from bitstrings, which were convoluted into analog target curves. The evolved output bitstring was convoluted to create the actual analog output curve. The fitness was defined in terms of how closely the evolved curve approached the target curve. These are very early results, and will very likely be improved upon as we become more experienced with dealing with the machine. In April 2000, the machine is still in its teething stage, but improving weekly.
Starlab will take possession of its CBM in June 2000. Also in June, Genobyte Inc, the designer and builder of the CBM, based on my ideas, will add Xilinx XC6264 chips to augment its present one-sixth version CBM to a full version. Then there will be 4 such machines in the world, with a possible 5th now in negotiation. The first, already delivered, remains at my previous lab ATR in Kyoto, Japan. It is being used by a former Japanese ATR colleague of mine (Hemmi). The 2nd machine was bought by and was delivered to Lernout and Hauspie (L&H), the Belgian speech processing company (worth now $8 Billion on the NYSE). They have set up a research team of several PhDs to investigate whether the CBM might be used to accelerate what their company does. The 3rd machine will arrive at my lab, STARLAB in June as I said above, and the 4th at the same time at Genobyte. A possible 5th machine is now being negotiated for.
Xilinx took the XC6264 chips off the market. They were not popular with electronic engineers because of their complexity of design. Genobyte managed to buy up the rest of them and hence there are only enough for about 3 more machines. We are now starting to think about the next generation of machine.
The images below give a taste of what the CBM can do. Im sure we will be able to do better as we continue to improve things and learn better tricks. The images contain self explanatory captions. Orange is the target curve, red is the evolved curve. Remember these curves evolved in second(s).
