Automatic medical diagnosis device - Part 1

One of my long term projects is to develope an automatic medical diagnosis device. During my research I came up with the so called naive Bayes classifier and started to learn about this kind of machine learning. In the attached PDF I use the example given on the wikipedia page but in greater details. If you want to learn more about naive Bayes classifier, I recommend the following one: http://guidetodatamining.com/guide/ch6/DataMining-ch6.pdf


How to make a medium size robot. Let's make a guide!

Now we have wonderful tutorials for making beginners and small robots, but bigger robot need stronger frame, motors, bigger batteries and can do much more work.

There are good examples of medium size robots here, but it would be useful to me and maybe others if there is a good comparison of various motors and drivers, how to get them and what to care about to avoid crashes and dangers.

Fast robot? (as in fast computing) how ?


So right now im planning for my first robot, I want my robot to be as fast as possible,  but I'm not talking speed wise(atleast not yet), rather 'computing'.

I'm thinking learn assembler ? I've understood its a painfull programming language to learn, but the programms are fast and powerfull. Offcource I could probaly solve my computational problems by just buying a faster ic, but those are difficult to get a holdof and not to mension expensive.

10.5.2010 so, just before competition ISTROBOT2010 i bought myself NXT2.0 set i started playing with it, went throught the first model of guard-shooter and started … Read more
