R7 Questions

Question 1

Turing’s B-unorganized machine consists of two things:

Answer 1

1. artificial neurons

2. devices that alter connections between those neurons

Question 2

Connection modifiers can be in two modes:

Answer 2

1. “pass mode”: where an input (zero or one) can pass through unaltered and turn into an output
2. “interrupt mode”: where an output is always one, regardless of what the input is

Question 3

Every neuron in the network executes this logical operation

Answer 3

NAND (“not and”)

Question 4

Why did Turing choose this logical operation?

Answer 4

NAND operator can replicate all other Boolean operators.

Question 5

Turing’s machine employs _____ of connections in training

Answer 5

the destruction & creation

Question 6

Give 1 example of a task that has been called “uncomputable”.

Answer 6

A universal Turing machine couldn’t be able to tell the difference between arithmetical theorems (7 + 5 = 12) and nontheorems.

Question 7

Turing and Church’s claims for the universal Turing machine have been commonly misstated. State them correctly.

Answer 7

Church and Turing’s claims didn’t exclude the possibility of hypermachines. They only stated that a universal Turing machine could mimic the behavior of a human mathematician that was working with paper and pencil.
