Define the decision task
Specify the environment, state representation, action space and reward signal so explanations map to meaningful domain concepts.
Explain reinforcement learning policies. Inspect and justify policy behaviour.
An explainable reinforcement-learning dashboard connects an agent's decisions to human-readable diagnostics: action-value estimates, reward attribution, and failure-case traces. Producing useful explanations requires instrumenting the environment, logging trajectories and designing visual summaries for non-expert reviewers. Common challenges include partial observability, stochastic rewards and non-stationary environments.

An explainable reinforcement-learning dashboard connects an agent's decisions to human-readable diagnostics: action-value estimates, reward attribution, and failure-case traces. Producing useful explanations requires instrumenting the environment, logging trajectories and designing visual summaries for non-expert reviewers. Common challenges include partial observability, stochastic rewards and non-stationary environments.
A proposed use-case is a researcher or engineer dashboard that surfaces why an agent chose particular actions, highlights low-confidence situations and allows manual overrides; a human reviewer should remain in charge for safety-critical decisions.
Specify the environment, state representation, action space and reward signal so explanations map to meaningful domain concepts.
Log states, actions, rewards and intermediate values (e.g. value estimates, policy logits) under training and evaluation episodes.
Start with simple baselines (epsilon-greedy, value-based or policy gradients) and record metrics and per-decision diagnostics.
Visualise per-action value estimates, feature attributions, counterfactuals and common failure traces for human inspection.
The supplied starter implements a 4-armed stochastic bandit with an epsilon-greedy action selection. It simulates 2000 steps, updates sample-average estimates for each arm, and prints action counts, estimated reward rates and total reward. There is no environment state, no policy-gradient or value-function agent, and no explainability or dashboard code.
for step in range(1, 2001):
if rng.random() < epsilon:
action = rng.integers(len(true_reward_rates))
else:
action = int(np.argmax(estimated_values))
reward = 1 if rng.random() < true_reward_rates[action] else 0
action_counts[action] += 1
total_reward += reward
estimated_values[action] += (reward - estimated_values[action]) / action_counts[action]This starter is a minimal multi-armed bandit simulation: it lacks an environment with states, no learned policy architecture (neural nets), no logging of per-decision diagnostics besides simple averages, and no UI or explainability methods. It cannot validate an explainable RL dashboard or cover policy-gradient/value-based RL scenarios.
A proposed extension is a lightweight dashboard that visualises per-action value estimates, action frequencies, cumulative reward curves and simple feature-attribution for decisions; include controls to replay trajectories and flag low-confidence actions for human review.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
