Expand description

Bundle of Burn tensors produced by PrioritizedBatch::to_burn_tensors.

Adds the per-sample importance-sampling weights on top of the ReplayBurnTensors field set. The trainer multiplies the per-row TD-error magnitude by is_weights before reducing to a scalar loss — this is the bias correction described in Schaul et al. §3.4.

Fields§

§observations: Tensor<B, 2>

Observations, shape [batch, obs_dim], dtype f32.

§actions: Tensor<B, 1, Int>

Discrete actions, shape [batch], dtype i64.

§rewards: Tensor<B, 1>

Rewards, shape [batch], dtype f32.

§next_observations: Tensor<B, 2>

Bootstrap-state observations, shape [batch, obs_dim], dtype f32.

§dones: Tensor<B, 1>

Episode-terminal mask (0.0 or 1.0), shape [batch], dtype f32.

§is_weights: Tensor<B, 1>

Importance-sampling weights, shape [batch], dtype f32, normalized so the max element is 1.0.
