Subject

Old: Simulating populations using AI.

New: Simulate the dancing behaviour of people in a bar or club.

When looking at Stratumseind these days, clubs and bars that were once flourishing look empty and silent. For a manager of such a bar, it may be difficult to decide what to improve to regain the glory of those golden days. Humans are complex, so their happiness and willingness to spend may depend on different factors combined in a specific way. Because of all these different factors, experimenting with them in real life is impossible work. On top of that, change in revenue might not be seen in a week, to be sure a longer observation period is needed. However, if you need to test a lot of different factors in a lot of different combinations, this takes ages.

That is where a simulation of the behaviours of the people in a bar or club might help. The simulation will make it easy to experiment with different factors, and adds the possibility to run multiple simulation in sequence. This way, certainty can be reached about the influence of a certain factor on the revenue, and managers of clubs and bars can come to decisions about what to improve to make their bar great again.

Objectives

• Main goal: assist the owner of a bar or dance hall with ideas on how to improve customer revenue.
• Construct an AI multi-agent simulation with which we can find what variables with what capacities are needed to maximize generated income.
• Analyse the reliability of such a simulation by discussing the observations of the client and the results of previous research done in this field (if any apply).
• Analyse the possibilities and shortcomings of such a simulation.

Research variables

General variables

• Income: The amount of money spent by patrons in order to buy alcohol
• music: Is there music present? if so, how loud is the music currently?
• Crowded level: How crowded is the bar/dance hall
• Dancing crowd: How many patron are currently dancing?

Patron specific variables

• Money: What amount of money do the patrons carry?
• Willingness to pay: How easy do the patrons part with their money in exchange for alcohol?
• Has alcohol: Patrons can get alcohol in exchange for money, which will slowly intoxicate them when consumed
• Intoxication: Intoxication changes the behaviour of a patron
• Alcohol tolerance: Patrons can endure only a specified amount of alcohol
• crowd sizes: In what group sizes can the patrons arrive and converse?
• Comfortability: Does the patron currently feel at ease?
• Dance affinity: Does the patron like to dance?
• Energy: All actions that a patron takes cost some energy.

Patron states

• Drinking: The only state that can be done simultaneously with any of the other states: In this state, the patron's alchohol will be drunk, increasing its intoxication level.
• Dancing: The patron is currently dancing and socialising with others. This actions does cost more energy than any other action.
• Talking: The patron is conversing with others, This does cost some energy.
• Buying: The patron is currently buying more alcohol for him/herself.
• Standing: In this state, the patron is inactive and unsocial. This state barely costs any energy.

Users

Old: Simulating populations can be useful in a lot of fields. A good-working simulation will therefore have a lot of users. Firstly, there are of course the biologists and behavioral analysts, who can perform experiments to try and understand populations better. A simulation like this can also be used in a population viability analysis, which is a species-specific method of risk assessment frequently used in conservation biology. Then we have the ecologists and government organisations who can use this tool for ecological risk assessment when they are making wildlife plans. Lastly, such a simulation can be useful in education to give students a better understanding of evolution and animal behaviour. (Avida-ED)

New (10/2): This simulator should prove useful to bar, club, dance or music events managers. Since this will help them with determining how to best get people dancing. Which for these managers in turn will mean more income. This could possible be used for other people who want to organize a personal event.

A secondary user for which this simulator might prove useful, are the people going to the bars, clubs, dance or music events. Assuming that customers spend more money when they enjoy themselves and leave when they do not, using the results of the simulator to improve bars would mean that bars become more enjoyable. This is beneficial for the customers: they will have a better time.

• Simulating exposure-related behaviors using agent-based models embedded with needs-based artificial intelligence (2018)

https://www.nature.com/articles/s41370-018-0052-y/ Context: HUMANS exposure to a chemical. Because descriptions of where and how individuals spend their time are important for characterizing exposures to chemicals in consumer products and in indoor environments, and the existing method is difficult and labor-intensive, a simulation of longitudinal patterns in human behaviour was created. This is an agent-based model with a needs-based AI. Needs-based because humans make their decisions to take actions in order to fulfil needs. The paper describes how it is implemented. Meets critical need in field of exposure assessment. Only addresses a few needs, and not the complex ones.

• Next-generation ecological risk assessment: Predicting risk from molecular initiation to ecosystem service delivery

https://www.sciencedirect.com/science/article/pii/S0160412016300824 There have been exciting developments in in vitro testing and high-throughput systems that measure responses to chemicals at molecular and biochemical levels of organization, but the linkage between such responses and impacts of regulatory significance – whole organisms, populations, communities, and ecosystems – are not easily predictable. This article describes some recent developments that are directed at bridging this gap and providing more predictive models that can make robust links between what we typically measure in risk assessments and what we aim to protect.

• Population based training of neural networks. Population based training discovers a schedule of hyperparameter settings rather than following the generally sub-optimal strategy of trying to find a single fixed set to use for the whole course of training.

• This paper explores novelty search, a new type of Evolutionary Algorithm, has shown much promise in the last few years. A common criticism of Novelty Search is that it is effectively random or exhaustive search because it tries solutions in an unordered manner until a correct one is found. Its creators respond that over time Novelty Search accumulates information about the environment in the form of skills relevant to reaching uncharted territory, but to date no evidence for that hypothesis has been presented.
