Define the MDP
Specify dialogue states, discrete actions (responses or prompts), reward signal from user feedback or scripted simulators, and termination rules.
Optimise dialogue policies. Manage reward trade-offs.
Conversational policy optimisation trains a policy to choose dialogue actions that maximise long-run user reward under constraints such as safety and coherence. Real setups define state, action and reward spaces from conversation logs or simulators, and evaluate with average return, sample efficiency and safety checks.

Conversational policy optimisation trains a policy to choose dialogue actions that maximise long-run user reward under constraints such as safety and coherence. Real setups define state, action and reward spaces from conversation logs or simulators, and evaluate with average return, sample efficiency and safety checks.
A proposed extension: build an experimental policy for a virtual assistant that suggests follow-ups while logging user feedback for human review. Human oversight is required for any live deployment to catch unsafe or misleading responses.
Specify dialogue states, discrete actions (responses or prompts), reward signal from user feedback or scripted simulators, and termination rules.
Replace the starter’s bandit with a conversation simulator or logged trajectories to produce stateful transitions for model-based or policy-gradient methods.
Run baseline policies (behavioural cloning, bandit baselines) then train value-based or policy-gradient agents and compare average return and stability across seeds.
Measure safety violations, response relevance and reward under adversarial or edge-case dialogues; include human review of flagged episodes.
The supplied starter implements an epsilon-greedy multi-armed bandit simulation with four Bernoulli reward arms. It uses NumPy to sample actions, update sample-average estimates, track action counts and print estimated reward rates and total reward. There is no conversation state, no policy-gradient or actor-critic training, and no dialogue data or simulator.
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]The code is a stateless multi-armed bandit demo: it lacks conversational states, action embeddings, reward shaping from dialogue outcomes, trajectory handling, and any reinforcement-learning algorithm for dialogue policies (no policy gradients, value networks, or environment interactions). It cannot validate conversational policy optimisation on real dialogue data.
A proposed extension is to connect a small conversation simulator or logged dialogue trajectories, implement a policy-gradient agent (e.g. REINFORCE) with state encodings, and compare it against the bandit baseline while logging safety metrics for manual 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.
