Scaling Value Iteration Networks

Scaling Value Iteration Networks (wip)

Exploration into the Scaling Value Iteration Networks paper, from Schmidhuber's group

Usage

import torch
from scaling_vin_pytorch import ScalableVIN

scalable_vin = ScalableVIN(
    state_dim = 3,
    reward_dim = 2,
    num_actions = 10
)

state = torch.randn(2, 3, 32, 32)
reward = torch.randn(2, 2, 32, 32)

agent_positions = torch.randint(0, 32, (2, 2))

target_actions = torch.randint(0, 10, (2,))

loss = scalable_vin(
    state,
    reward,
    agent_positions,
    target_actions
)

loss.backward()

action_logits = scalable_vin(
    state,
    reward,
    agent_positions
)
