Struct ContinuousQNetworkConfig 

pub struct ContinuousQNetworkConfig {
    pub num_layers: usize,
    pub hidden_dim: usize,
    pub use_orthogonal_init: bool,
    pub activation: BurnActivation,
    pub seed: Option<u64>,
}

Configuration for ContinuousQNetwork architecture.

Mirrors crate::policy::q_network::QNetworkBurnConfig but adds the depth/activation knobs SAC critics want (the default SAC critic is a 2-layer, 256-wide ReLU MLP per Haarnoja et al. 2018). Held as a separate type so the critic can be tuned independently of the actor.

Fields

num_layers: usize

Number of hidden layers in the trunk. Only 2 or 3 are supported; anything else is treated as 2.

hidden_dim: usize

Width of every hidden layer.

use_orthogonal_init: bool

If true, initialize hidden-layer weights with orthogonal (gain sqrt(2)) and the Q-head with gain = 0.01. Set false for Burn’s stock Kaiming-uniform default.

activation: BurnActivation

Activation applied between hidden layers.

seed: Option<u64>

Optional construction seed. When Some, every layer is built from a deterministic, StdRng-driven weight buffer (see crate::policy::seeded_init) so two constructions with the same seed produce bit-identical critics. When None (the default) Burn’s unseedable Initializer path is used verbatim. Twin critics should be seeded differently (or left unseeded) so they are decorrelated.

Implementations

impl ContinuousQNetworkConfig

pub fn with_seed(self, seed: u64) -> Self

Set the construction seed, enabling the deterministic host-side init path in ContinuousQNetwork::with_config.

Builder-style; returns self for chaining: ContinuousQNetworkConfig::default().with_seed(42).

Trait Implementations

impl Clone for ContinuousQNetworkConfig

fn clone(&self) -> ContinuousQNetworkConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ContinuousQNetworkConfig

impl Debug for ContinuousQNetworkConfig

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

Formats the value using the given formatter.

impl Default for ContinuousQNetworkConfig

fn default() -> Self

Returns the “default value” for a type.
