## What does the XOR operator do?

• Short for eXclusive OR, the XOR operator is a Boolean operation used in database searches and other searches that returns a TRUE value only if a document contains only one match. In the above example, the command would return results of documents or a value that contain either "computer" or "help".

## What is exclusive OR (XOR)?

• Exclusive or. Exclusive or or exclusive disjunction is a logical operation that outputs true only when inputs differ (one is true, the other is false). It is symbolized by the prefix operator J and by the infix operators XOR (/ˌɛks ˈɔːr/), EOR, EXOR, ⊻, ⊕, ↮, and ≢.

## What does a XOR gate do?

• XOR gate. The XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true.

## What is a XOR problem?

• The XOR Problem. The XOR,or "exclusive or",problem is a classic problem in ANN research. ...
• Perceptrons. Like all ANNs,the perceptron is composed of a network of*units*,which are analagous to biological neurons.
• Multilayer Perceptrons. ...
• Backpropagation. ...
• Conclusion. ...

## How does the XOR work?

• An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results. XOR represents the inequality function, i.e., the output is true if the inputs are not alike otherwise the output is false.
