Struct UniformBernoulliBandits

pub struct UniformBernoulliBandits {
    pub num_arms: usize,
}

A distribution over Beroulli bandit environments with uniformly sampled means.

The mean of each arm is sampled uniformly from [0, 1].

Reference

This environment distribution is used in the paper “RL^2: Fast Reinforcement Learning via Slow Reinforcement Learning” by Duan et al.

Fields

num_arms: usize

Number of bandit arms.

Implementations

impl UniformBernoulliBandits

pub const fn new(num_arms: usize) -> Self

Trait Implementations

impl Clone for UniformBernoulliBandits

fn clone(&self) -> UniformBernoulliBandits

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UniformBernoulliBandits

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UniformBernoulliBandits

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for UniformBernoulliBandits

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl EnvDistribution for UniformBernoulliBandits

type State = <<UniformBernoulliBandits as EnvDistribution>::Environment as Environment>::State

type Observation = <<UniformBernoulliBandits as EnvDistribution>::Environment as Environment>::Observation

type Action = <<UniformBernoulliBandits as EnvDistribution>::Environment as Environment>::Action

type Feedback = <<UniformBernoulliBandits as EnvDistribution>::Environment as Environment>::Feedback

type Environment = Bandit<Bernoulli>

fn sample_environment(&self, rng: &mut Prng) -> Self::Environment

Sample an environment from the distribution.

impl EnvStructure for UniformBernoulliBandits

type ObservationSpace = SingletonSpace

type ActionSpace = IndexSpace

type FeedbackSpace = IntervalSpace<Reward>

fn observation_space(&self) -> Self::ObservationSpace

Space containing all possible observations.

fn action_space(&self) -> Self::ActionSpace

The space of all possible actions.

fn feedback_space(&self) -> Self::FeedbackSpace

The space of all possible feedback.

fn discount_factor(&self) -> f64

A discount factor applied to future feedback.

impl Hash for UniformBernoulliBandits

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for UniformBernoulliBandits

fn eq(&self, other: &UniformBernoulliBandits) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for UniformBernoulliBandits

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
