Had a lecture yesterday about neural nets. Some of you may know what these are, some may not. For those that don't, here's a quick run-down - based on my understanding.
Nueral nets are a network of neurones. Funny that. A neurone has many inputs, and only one output. Each input is weighted, in that input 1 may have a weighting of 10, and input 2 has a weighting of 1. Therefore, input 1 is much more important than input 2. With me so far? Right.
If you have a neurone with 10 inputs, the threshold level may be, say, 50. This means that when the inputs are multiplied by their respective weightings, if the results is over 50, then the output is active. Otherwise the output is not active.
Here's a slightly simpler example:
A neuron has 3 inputs, with different weightings:
Input 1 has a weighting of 11.
Input 2 has a weighting of 6.
Input 3 has a weighting of 5.
The threshold level is 10. So, if input 1 is active, then the output is active as the threshold level is reached. If input 1 is not active, then the threshold level can still be reached if both input 2 AND input 3 are active.
If you're not with me, go back and read it again. It does make sense. Promise :-)
People are trying to write computer programs that can represent complex neural nets, as these nets can learn - essentially true Artificial Intelligence.
So what happens in the future when (and it WILL happen, just maybe a few hundred years from now) we create proper AI. Will they have legal rights? Would it be right to give them dangerous jobs? Only allow them certain thoughts and feelings?
Were is the line drawn between man and machine?
This is a difficult question, when you consider that the average human brain is comprised of around 100 BILLION neurones. But if neurones merely react to their inputs (like a computer program), then we have no control over them. Therefore we have no control over our actions.
Because of this we are not guilty of anything. Nor can we take credit for anything. We are just machines. Effectively.
Thoughts? (if you can call them that...)
