The Turing test

In this section we explore the most famous and iconic machine intelligence test: the Turing test.

Initially proposed in 1950 by the famous mathematician Alan Turing, the Turing test introduces very important elements to our quest to define the specifications of an intelligent and conscious machine.

Ultimately, we will find that the Turing test is excessive in some areas and insufficient in others. We will thus reject the Turing test as an overall specification.

However, on the way, we will further develop the definition of machine intelligence, we will explore variations of the test and their consequence on machine behavior and we will propose a realistic implementation strategy to achieve, today, a very strong version of the Turing test.



Turing's black box

E-mail Print

In this section we describe the Turing test, we explore the key assumption that underly this test of machine intelligence, we examine the links between the test and the black box concept, we formulate a chess-based version of the test, we look at the semantic and bandwidth requirements of the test.

Turing variation: Trusting Turing

E-mail Print

In the standard version, the human evaluator knows that his interlocutor may be a machine. A weaker version, where the human does not suspect this is usually called blind Turing. We call it Trusting Turing because it exhibits non probing behavior and is linked to another situation: Knowing Turing. Trusting and knowing Turing provide us with a useful indicator of consciousness.

Turing variation: Turing tag

E-mail Print

Turing tag is a variant of the Turing test modelled on speed dating. This variant allows us to provide a first basic definition of the Belief state of a conscious entity.

Turing variation: Assisted Turing

E-mail Print

Turing Tag and Turing Fest lead us to the last and most important variation of the Turing test: Assisted Turing. Assisted Turing appears to be a more limited and simpler version of the Turing test. In fact it is more powerful and will be a componenet in the initial design layer (Layer 0) of the blueprint.

PEDO-NAB a Turing test implementation strategy

E-mail Print

It is possible, with today’s technology, to develop a system capable of achieving the Turing test. The primary obstacle to the realization of this objective is not technical, it is financial. The PEDO-NAB project, proposed here, would justify a significant financial investment in applications that can pass the Turing Test.

Turing variations: Converse Turing

E-mail Print

There is something intellectually pleasing about the Turing test. The self contained simplicity of the test allows for myriad variations, each of which is more interesting than the previous one. Many variations will be examined, some of them original. The first one is a classic: Converse Turing.

Turing variation: Turing's Gambit

E-mail Print

In the Turing test, the hidden interlocutor may not be a computer. Also, both interlocutors may be tasked to evaluate if the other is a machine. This is the Double Turing scenario. Turing's Gambit is an effective machine strategy in a Double Turing situation. If the conjecture is correct, it highlights the social components of consciousness.

Turing variation: Turing Fest

E-mail Print

The Turing tag described previously is analogous to a single encounter within a speed dating event. The Turing Fest is analogous to a speed dating meet involving dozens or hundreds of participants. Turing Fests would be an ideal venue to develop Belief models.

A definition of machine intelligence

E-mail Print

As we saw earlier, the Core Conditions of Consciousness allowed us to provide a first definition of intelligence that is general and yet precise enough for machine implementation. Our analysis of Turing's black box leads to a more precise formulation of this definition.

Excessive, insufficient and a test

E-mail Print

By defining his wonderful intellectual construct, The Turing Test, Alan Turing provided us with a key concept: the primary indicator of machine intelligence is not in the machine’s behaviour itself but the observed behaviour of the humans that interact with it. However, the test he proposed is ultimately unsuitable as a measure of machine consciousness because it is both excessive and insufficient and because it is a test.
