In this portfolio we describe the threshold logic unit (TLU) as presented by McCulloch and Pitts (1943) as an example of a simple artificial neuron. We name and describe each of the components and their biological analogies. We describe how the TLU as a whole functions, and how networks of TLUs function. We conclude by comparing the function of TLUs to its contemporaries and successors.
After reading this portfolio, we expect the reader to be able to:
- List the component parts of a simple artificial neuron.
- Draw a labelled diagram of a simple artificial neuron.
- Describe the function and operation of:
- The input lines.
- The weights.
- The summation unit.
- The threshold unit.
- The output lines.
- Describe the function and operation of the whole structure.
- Describe how a neuron fits into a network.
