Do you know any example for this topic?.
I have searched google but had no luck with any Decision Making using Artificial Intelligence example ( at least any truly developed)

Answer 1

i have an example for decision making in AI. it is about choosing a dress to purchase. It asks for inputs as follows:
1) Whether you are Male or Female
2)Price range must be less than 1000 or greater than 1000
3)Age <20 or >20
Based on these inputs , my code will analyse which type of dress suits you and in which shop you can purchase it. I have just given few knowledge in my code. Only 3 shop's names i have kept in my knowledge base.
It gives output as a percentage .
Eg) Shop A: 20.5%
Shop B: 40.5&
Shop C: 39.0%
This means that you have high probability of finding your favourite dresses in Shop B.

Read this. There are different ways to go about AI decision making. The examples are on the bottom.

Answer 3

Decision-making (DM) is a topic widely studied by different fields of science. (Cognitive sciences, Neurosciences, Computer sciences, Behavioral Economics, Operations research, etc. *1)
However, DM problems are varied and the computational approach to address that problem will vary accordingly. For instance:
If you have to make a frequent decision that affects the previous one you are dealing with a sequential DM problem. In those cases, reinforcement learning *2 or deep reinforcement learning *3 can be used to tackle this problem. Examples of these problems can be seen in video-games where the game AI needs to take different actions (policies) over time to maximise its score. (reward)
If you the problem is not sequential but you deal with multiple criteria to find the most attractive alternative then you are dealing with a multi-criteria decision-making problem, topic widely researched in operations research. There are some typically-used algorithms that are utilised to assist human-decision making like AHP*4, TOPSIS*5, ELECTRE*6, PROMETREE*7. An example of MCDC is selecting a house to buy, where you have to consider location, price among other desirable or undesirable characteristics.
Depending on the level of uncertainty, subjective data and incomplete information of the problem you might require to use fuzzy, intuitionistic or neutrosophic variations of the mentioned algorithms. *8
You might need to optimise DM through different competing goals. In that case, you are dealing with a multi-objective decision-making optimisation problem (MODM). See Decision trees*9, genetic algorithms*10 .
Furthermore, a DM problem can have different 'agents' making decision that can affect ours. So that is known as 'multi-agent' decision-making. In computer science, multi-agent system simulations are commonly used to research these problems. *11
You can also have the case where the agents have to make a collaborative decision that affects all of them. So that is known as 'group' decision-making.
In the industry, computational DM can be seen with the widely used recommender systems such as the ones in Netflix or Amazon.*13 In the B2B sector, AI in DM can be seen in decision-support systems and prescriptive analytics services *14.
I hope you find that information useful. There is indeed, much more about this complex topic, I just tried to summarise.

Answer 4

There are simply too many examples to count! The whole (large) field of expert systems development, for example, consists of building programs whose explicit purpose is to emulate human decision making. Google "expert systems" to find thousands of examples.
I'll put in a plug for Jess, an expert system shell written in Java which I developed. It's used by thousands of companies world wide to automate decision-making processes.

Answer 5

I did a bit of browsing on the web and I came across this example project.
You might also check out the AI-Depot website here.
Probably the reason there are not so many working examples is because AI decision algorithms, such as neural networks, genetic algorithms, and decision trees get very complex, very quickly. Most developers of such algorithms, at least the algorithms that are stable and actually work, are very protective of their IP. And, for good reason.
In any case, hope this helped.
