- Synaptic weights
!
A neural network is a directed graph consisting of nodes with interconnecting synaptic and activation links, and is characterised by four properties
- Each neuron is represented by a set of linear synaptic links, an externally applied bias, and a possibly nonlinear activation link. The bias is represented by a synaptic link connected to an input fixed at +1
- The synaptic links of a neuron weight their respective input signals
- The weighted sum of the input signals defines the induced local field of the neuron in question
- The activation link squashes the induced local field of the neuron to produce an output
Knowledge
Knowledge refers to stored information or models used by a person or machine to interpret, predict, and appropriately respond to the outside world
Made up of:
- The known world state
- Represented by facts about what is and what has been known
- Prior information
- Observations of the world
- Usually inherently noisy
- Measurement error
- Pool of information used to train
- Can be labelled or not
- (Un-)Supervised
Knowledge representation of the surrounding environment is defined by the values taken on by the free parameters of the network
- Synaptic weights and biases
