Deep Reinforcement Learning is a type of machine learning where an agent Learns by doing actions in an enviornment and recive feedback.

Unit 1

Agent/Entity/Model --> Action --> Environment --> Result

What is Reinforcement Learning?(intutition)

Imagine taking a quiz without prep(same set of questions), review the quiz after 1st attempt, Identify correct and incorrect answers, Another attempt. Repeat, In a cyclic fashion until the quiz is cleared.

  • Environment(quiz)
  • Agent(Human)
  • Guessing Answers(Trial and error)
  • Reward(Correct and Incorrect answers).

Idea behind RL is an agent learns from the environment by making actions(trial and error) and recieveing rewars(positive or negative) for those actions.

RL is a framework to solve decision or control problems.

Reinforcement Learning Framework

  1. RL outputs a sequence of State, Action, Reward, NextState
  2. Central idea of RL is reward hypothesis - All goals(tasks) can be viewed as maximizing cumulative reward called as expected return.
  3. That’s why in RL to achieve best behaviour, learn to take actions that maximize expected cumulrative reward.
  4. In Papers RL is called Markov Decsions Process. MDP states, we only need the current state to decide the action and not history of all states.
  5. Observations - Entire state of environment is described or available. State - Partial State of environment. Chess Game and Mario game respectivley.
  6. Actions: Discrete(finite moves) - Tetris Games, Continuous - Driving cars.
  7. Reward with Discount(gamma) - For every actions, we calculate reward with discount exponent(step). Discount determines what the agent cares for long-term reward(larger gamma) and shot-term reward(smaller gamma). Discount depends on risk of achieveing a desired state with action. Then this is cumulativley summed up to get final reward - expected return.

Tasks

  1. Episodic - Has starting point and ending point, This creates an episode: list of states, actions, rewards, next states.
  2. Continuing - Predicting stock market, learning to choose best actions and interacting with environmen is simulatneous.

Exploration/Exploitation Trade-off

  1. Exploration - Unkown random actions to find more about environment.
  2. Exploitation - Repeating known actions to maximize reward.

Two main approaches for solving RL Problems

  • Reward function - actions to maximize expected cumulative reward. This is what needs to be learned?
  • Policy is how we learn this. Policy is a function to be learned. Optimal policy maximizes expected return when agent actions according to it.
  • Policy - Agent’s brain, function - to take actions that maximizes expected reward.
  • Two way’s to train to find optimal policy. Policy-Based and Value-Based.
  • Policy-Based: Learn function directly which action to take. Two ways:
    1. Deterministic: returns one action.
    2. Stochastic: returns probabilites for actions.(Given state, conditional probability) - P(A S) where A is set of Actions S is state.
  • Value-Based: Value: Action-Value function, most valuable action to take given a state and action.

gymnasium is the library with implementations of common reinforcement learning environments. It provides an API to do this. Env a imperfect reconsturction of Markov Decision Process is the core. This class provies users ability to generate initial state, make actions, move to new states and visuaize the environment. Main Components are:

  • make() - Create environemet. Returns Env.
  • Env.reset() - Reset’s environment.
  • Env.step() - Make an action.
  • Env.render() - Visualize environment.

RL Loop has four steps: S0 -> A0 -> S1 -> R1

  • S0 - Current state
  • A0 - Action
  • S1 - New State
  • R1 - Reward

Let’s create an environment in gymnaisum to understand the code.

# create environment
env = gymnasium.make("LunarLander-v2")
# Checkout env attributes
vars(env) # Docs: https://gymnasium.farama.org/api/env/

Each observation is a vector of shape 8. Why?. Excerpt from source:

` Observation Space: The state is an 8-dimensional vector: the coordinates of the lander in x & y, its linear velocities in x & y, its angle, its angular velocity, and two booleans that represent whether each leg is in contact with the ground or not. `

Action space has four actions: Excerpt from source:

There are four discrete actions available:

- 0: do nothing
- 1: fire left orientation engine
- 2: fire main engine
- 3: fire right orientation engine
env.action_space.n,
(np.int64(4),)

Reward:

- Is increased/decreased the closer/further the lander is to the landing pad.
- Is increased/decreased the slower/faster the lander is moving.
- Is decreased the more the lander is tilted (angle not horizontal).
- Is increased by 10 points for each leg that is in contact with the ground.
- Is decreased by 0.03 points each frame a side engine is firing.
- Is decreased by 0.3 points each frame the main engine is firing.
- Additional reward of -100 or +100 for crashing or landing.
- Episode is considered a solution if it scores at least 200 points.

Now, We’ve an environment(from gymnasium). Next we need an RL algorthim, eval etc to learn a policy with a model/agent.

We’ll use PPO reliable implementation from stable-baselines3. We’ll dive into PPO later!

We’ll use make_vec_env() from stable-baelines3 to create n environments. n individual environments are stacked into a single environment. This allows us to train an agent in n environments per step. Now actions, observations, rewards have an additional dimension n.

PPO is the algorithm, it has two policies MlpPolicy(vector inputs) and CnnPolicy(frame inputs).

Let’s to a training run with PPO.

env = gymnasium.make("LunarLander-v2", render_mode="rgb_array")
model = PPO(
    policy="MlpPolicy",
    env=env,
    verbose=1,
)

Next, let’s try out a different model, log metrics, save video per epoch(with callback) and visualize them. Try out a differnt model perhaps.

Huggy

In this we’re gonna use Huggy environment from Unity-Technolgies/Ml-Agents. This toolkit enables to use games and simulations as environments to train Agents.

Here we’re gonna train Huggy(dog) with motor joints to fetch stick.

Environment state:

  1. Target(stick) position.
  2. Relative position between Huggy and Target.
  3. Orientation of legs.

Action: Moves huggy can do.

In RL we’ve to maximize the expected return(cumulative reward). Reward is to fetch the stick with Huggy.

We want Huggy to get in least possible time. Below are the rewards and penalties(i.e reward function):

  1. Orientation bonus: Reward to getting close to target.
  2. Time Penalty: Fixed time penalty to push Huggy to get to the target asap.
  3. Penalty for spinning at a single place or spinning too much: Rotation penalty.
  4. Target reward: Getting the stick.
  • RL Loop: State_0(Target, Huggy-distance-target, legs orientation) –> Action_0(motor joints movement) –> Next_state_1(Target, Huggy-distance-target, legs orientation) –> Reward_0(above 4 points)
  • Environment: Stick is spawned randomnly, when Huggy reaches it.

Let’s dive into code. Python version should match with ml-agents python version. python_requires=”>=3.10.1,<=3.10.12” - This is in ml-agents/setup.py.

!python --version
# Install virtualenv and create a virtual environment
!pip install virtualenv
!virtualenv myenv

# Download and install Miniconda
!wget https://repo.anaconda.com/miniconda/Miniconda3-latest-Linux-x86_64.sh
!chmod +x Miniconda3-latest-Linux-x86_64.sh
!./Miniconda3-latest-Linux-x86_64.sh -b -f -p /usr/local

# Activate Miniconda and install Python ver 3.10.12
!source /usr/local/bin/activate
!conda install -q -y --prefix /usr/local python=3.10.12 ujson  # Specify the version here

# Set environment variables for Python and conda paths
!export PYTHONPATH=/usr/local/lib/python3.10/site-packages/
!export CONDA_PREFIX=/usr/local/envs/myenv
!python --version

Now python version matches ml-agents python version. Let’s install the packages.

!git clone --depth 1 https://github.com/Unity-Technologies/ml-agents
# Go inside the repository and install the package (can take 3min)
%cd ml-agents
!pip3 install -e ./ml-agents-envs
!pip3 install -e ./ml-agents

Environment is available in a zip file. Let’s download the env and place it in a directory.

!mkdir ./trained-env-execs
!mkdir ./trained-env-execs/linux
# Download
!wget "https://github.com/huggingface/Huggy/raw/main/Huggy.zip"
!mv "Huggy.zip" "./trained-env-execs/linux/Huggy.zip"
!unzip -d ./trained-env-execs/linux ./trained-env-execs/linux/Huggy.zip
# Check executable is accesible
!chmod -R 755 ./trained-env-execs/linux/Huggy

To train Agent with ml-agents framework, we’ve to create a yaml file in the respective algorithm directory. It has for algorithms:

  1. imitation
  2. poca
  3. ppo
  4. sac

We’re gonna train with PPO, let’s create ml-agents/config/ppo/Huggy.yaml with below parameters.

behaviors:
  Huggy:
    trainer_type: ppo
    hyperparameters:
      batch_size: 2048
      buffer_size: 20480
      learning_rate: 0.0003
      beta: 0.005
      epsilon: 0.2
      lambd: 0.95
      num_epoch: 3
      learning_rate_schedule: linear
    network_settings:
      normalize: true
      hidden_units: 512
      num_layers: 3
      vis_encode_type: simple
    reward_signals:
      extrinsic:
        gamma: 0.995
        strength: 1.0
    checkpoint_interval: 200000
    keep_checkpoints: 15
    max_steps: 2e6
    time_horizon: 1000
    summary_freq: 50000

Now let’s train this agent. We’ve env, agent, parameters to train.

!mlagents-learn ./ml-agents/config/ppo/Huggy.yaml --env=./trained-env-execs/linux/Huggy/Huggy --run-id="Huggy1" --no-graphics
from huggingface_hub import notebook_login
notebook_login()
# Let's push this model to hub
