Representation Flashcards
1
Q
What is the input space
A
a graph of all possible input values of a vehicle or neuron.
2
Q
What is a decision boundary
A
A straight line which can be drawn on the input space to seperate positive and negative outputs of a vehicle or neuron.
3
Q
How can you find the decision boundary of a vehicle/ neuron
A
- Replacing the expression output with a 0
- Rearranging so that s1 and s2 are on either side to form an equation which looks like y=mx +c
s1 and s2 are y and x. And m and c are affected by the weights and the wires.
4
Q
What is a bias term ?
A
can be introduced so it is possible to draw any line in the input space for instance. w3 - this will affect the y intercept.
-s1 = s2w2/w1 + w3/w1
5
Q
Can single neurons solve non linear problems
A
NO but neural networks can.
