How will the data scientist MOST effectively model the problem?
The data scientist should obtain a correlated equilibrium policy by formulating this problem as a multi-agent reinforcement learning problem.
The data scientist should obtain the optimal equilibrium policy by formulating this problem as a single-agent reinforcement learning problem.
Rather than finding an equilibrium policy, the data scientist should obtain accurate predictors of traffic flow by using historical data through a supervised learning approach.
Rather than finding an equilibrium policy, the data scientist should obtain accurate predictors of traffic flow by using unlabeled simulated data representing the new traffic patterns in the city and applying an unsupervised learning approach.
Explanations:
Modeling traffic as a multi-agent reinforcement learning (MARL) problem allows each traffic light (agent) to interact and learn optimal behaviors that lead to a correlated equilibrium policy, which is suitable for handling interdependent traffic flows with stochastic variations.
A single-agent reinforcement learning (RL) approach would not adequately capture the multi-agent interactions and dependencies present at different traffic lights, as each light’s actions affect the others.
While supervised learning could predict traffic flow, it would not capture the dynamic and interdependent nature of traffic light interactions necessary for real-time congestion reduction.
An unsupervised learning approach with unlabeled simulated data would be ineffective for predicting or optimizing traffic flow patterns, as it lacks the structure required to model policy-based decision-making for interdependent traffic signals.
As I understand it, the answer is:
The data scientist should obtain a correlated equilibrium policy by formulating this problem as a multi-agent reinforcement learning problem.
