Neural Networks Basics

Deep Learning is a subfield of machine learning.

• True

• False

The bias b is like a weight w in a single-input neuron, except that its input value is 1.

• True

• False

Typically, a neuron has exactly one input.

• True

• False

Single-layer networks are more powerful than multilayer networks.

• True

• False

The line w₁x₁ + w₂x₂ + b = 0 passes through the origin if b = 0.

• True

• False

The weight vector should be orthogonal to the perceptron decision boundary.

• True

• False

The Perceptron Learning Algorithm can solve linearly inseparable problems.

• True

• False

The inner product a⋅b will be negative when the angle between vectors a and b is less than 90 degrees.

• True

• False

Which of the following Boolean functions can not be represented by a single-neuron perceptron?

• XOR

• OR

• AND

• NOT

Suppose that a decision boundary is defined by the line x₁ - 2x₂ = 0. What will you predict the label of the point x = (-1, 1)?

• can be 1 or -1

• 1

• -1

• 0
