Neuron Models
- Models and Toothbrushes
- The best models are compartmental models. Some neurophysiologists
call them explanations.
- Of course, they're a bit computationally expensive, so most
AI people work with simple point models.
- The simplest is integrate and fire (McCulloch and Pitts or Lapicque).
- That's been used by Hopfield too.
- There's a fair bit of work with Leaky Integrate and Fire.
- OReilly and others avoid spiking and have continuous output models.
- I also think Boltzmann machines that fire regularly without input
are good.
- Almost all of my work has been with Fatiguing Leaky Integrate and
Fire neurons.
- I'm starting to play with compartmental models.
- Note that there are lots of different types of neurons.
- Izhikevich has a good two parameter model for accounting for
different types of neurons.
- One big division (oversimplified) is between inhibitory and
excitatory neurons.
