GWT: Global Workspace Theory Cognitive Augmentation Library

An enterprise-grade, lightweight, and mathematically rigorous PyTorch cognitive augmentation library. Based on the cognitive science principles of Global Workspace Theory (GWT), active dendritic processing, metacognitive neuromodulation, and glial homeostasis, GWT enables developers to augment any open-weights foundation model (such as Llama-3, Mistral, ResNet, and Vision Transformers) with state-of-the-art brain-inspired routing, active gating, and local learning regulation.

1. Package Executive Overview & Installation

Architectural Overview

The GWT library acts as a framework-agnostic, low-overhead cognitive layer that hooks into PyTorch models (Transformers, CNNs, and Spiking Neural Networks) without requiring intrusive alterations to their source code. By leveraging PyTorch forward and backward hooks, GWT intercepts intermediate representations, routes them through a central workspace bottleneck where they compete for attention, and broadcasts a unified cognitive context vector back to all subsystems.

Key Biological Paradigms

Global Workspace Bottleneck (Phase v0.1): Collapses high-dimensional representation spaces into a selective, low-dimensional competitive broadcast.
Active Dendritic Gating (Phase v0.2): Simulates compartmental dendritic trees where GWT context filters and modulates feedforward inputs via NMDA-like threshold spiking.
Episodic Consolidation & Synaptic Homeostasis (Phase v0.3): Executes offline sleep-replay cycles and permanently prunes underutilized synapses using backward gradient lockout hooks.
Metacognitive Neuromodulation (Phase v0.4): Automatically tunes hyperparameter knobs based on temporal cosine surprise (Norepinephrine) and entropy focus (Acetylcholine).
Glial Metaplasticity & Excitotoxicity Protection (Phase v0.5): Employs virtual astrocytes to scale local learning rates and damps excessive gradient variance locally.
Conceptual Bottlenecks & Causal Interventions (Phase v0.6): Maps representations onto explicit concept activation scores in $[0, 1]$, enabling human-in-the-loop causal overrides.
Cross-Modal Cognitive Crossbar (Phase v0.7): Routes information concurrently across multiple parallel slots using multi-slot attention routing.
Enterprise Scalability & Caching (Phase v0.8): Offloads heavy SWS consolidation loops asynchronously and serializes/deserializes PyTorch activation tensors to/from Redis Enterprise.
Autonomous Computational Neurogenesis (Phase v0.9): Dynamically spawns new parallel dendritic branches in response to high unexpected uncertainty, protected by somatic calcium regulators and offline pruning consolidation.

Developer Quick-Start

The following script demonstrates how to instantiate the engine, register a simple PyTorch layer with a dendritic adapter, execute a forward and stepping loop, and print the live ASCII diagnostic panel:

import torch
import torch.nn as nn
from gwt import (
    CognitiveAugEngine,
    GlobalWorkspace,
    DendriticModuleAdapter,
    MetacognitiveMonitor,
)

# 1. Define a standard PyTorch module
class VisionEncoder(nn.Module):

        super().__init__()
        self.conv = nn.Conv2d(3, 8, kernel_size=3, padding=1)
        self.fc = nn.Linear(8 * 4 * 4, 16)

    def forward(self, x: torch.Tensor) -> torch.Tensor:
        out = torch.relu(self.conv(x))
        out = out.view(out.size(0), -1)
        return self.fc(out)

# 2. Instantiate modules and engine
device = torch.device("cuda" if torch.cuda.is_available() else "cpu")
model = VisionEncoder().to(device)

engine = CognitiveAugEngine()

# 3. Register standard module with a Dendritic Adapter

    name="vision_encoder",
    module=model,
    latent_dim=16,
    data_flow=engine.data_flow,
    num_branches=4,

# 4. Attach Workspace and Neuromodulator

engine.attach_workspace(workspace)

monitor = MetacognitiveMonitor(alpha_ne=0.2, alpha_ach=0.2)
engine.attach_neuromodulator(monitor)

# 5. Run standard forward pass & step GWT cycle
inputs = torch.randn(4, 3, 4, 4, device=device)
outputs = model(inputs)  # Adapter automatically intercepts latents via hooks

broadcast_state = engine.step()  # Computes GWT routing and ACh/NE curves

print(f"[*] Broadcast Context Shape: {broadcast_state.shape}")

3. Memory Safety & Production Best Practices

To deploy GWT in high-throughput enterprise systems with billions of parameters, developers must follow these critical production paradigms.

1. Guaranteeing Autograd Graph Isolation

PyTorch builds a directed acyclic graph (DAG) during the forward pass to track operations for backpropagation. If transient or historical representations (e.g., past global broadcasts, stored episodic memory traces, or moving average scores) are kept across stepping cycles without gradient isolation, autograd continues to accumulate the graph indefinitely. This results in a catastrophic memory leak and eventual Out-Of-Memory (OOM) crashes.

Solution

GWT guarantees graph isolation by explicitly detaching historical states at critical boundaries:

Episodic memory writing: When writing state transitions to the CognitiveReplayBuffer, GWT enforces .detach().clone() on all captured latents, separating them from active computational subgraphs.
Gradient-free monitoring: All neuromodulation updates (calculating ACh focus and NE surprise curves) and local ASTROCYTE learning rate tracking run inside with torch.no_grad(): blocks, preventing tracking variables from generating unnecessary gradient dependencies.
Detached working memory decay: In short-term memory transitions, active slot decay operations use in-place multiplication operations on detached tensors.

# Enterprise Best Practice: Detach caching states to guarantee zero memory leaks
latent_state = adapter.data_flow.get_buffer("subsystem").detach().clone()

2. Dimension Agnosticism (Rank-Agnostic Pooling)

Foundation models utilize diverse activation tensor ranks across modalities:

Transformers (e.g., Llama-3): Output sequence arrays with shape [Batch, Sequence, Dim].
CNNs (e.g., ResNet): Output spatial feature arrays with shape [Batch, Channel, Height, Width].
Standard MLPs: Output flat state vectors with shape [Batch, Dim].

GWT's global_pool_latent seamlessly accepts arbitrary multi-dimensional tensors and collapses spatial/temporal channels dynamically into flat 2D [B, D] dimensions. This guarantees that deep-learning outputs can interface cleanly with GWT's low-dimensional concept bottlenecks without manual shape resizing.

def global_pool_latent(x: torch.Tensor) -> torch.Tensor:
    if x.dim() == 2:
        return x
    elif x.dim() == 3:
        # Collapse sequence length dimension [B, S, D] -> [B, D] via average pooling
        return x.mean(dim=1)
    elif x.dim() == 4:
        # Collapse spatial dimension [B, C, H, W] -> [B, C] via adaptive average pooling
        return F.adaptive_avg_pool2d(x, (1, 1)).flatten(start_dim=1)
    else:
        return x.flatten(start_dim=1)

3. Hyperparameter Configuration Guidelines

For stable learning convergence under complex 7-phase neuro-cognitive loops, configure hyperparameter ranges according to these empirical baseline settings:

Parameter	Type	Default	Recommended Range	Description
`alpha_ne`	`float`	`0.8`	`0.3 - 0.9`	Surprise decay smoothing rate. Lower values accelerate adaptation.
`alpha_ach`	`float`	`0.8`	`0.3 - 0.9`	Focus decay smoothing rate. Lower values enable faster attention shifts.
`lr_lock_scale`	`float`	`0.5`	`0.1 - 0.8`	Glial damping scale for stable focus states.
`lr_unlock_scale`	`float`	`1.5`	`1.1 - 3.0`	Glial boosting scale for surprising/novelty states.
`max_variance_threshold`	`float`	`3.0`	`2.0 - 5.0`	Excitotoxicity limit. Standard deviation limit before gradient damping triggers.
`damping_factor`	`float`	`0.2`	`0.05 - 0.5`	Glial damping multiplier applied to local gradients during spikes.
`pruning_threshold`	`float`	`0.05`	`0.01 - 0.2`	Minimum average activation threshold below which dendritic branches are pruned.

4. Verification and Local Testing

Run GWT's full unit and integration test suite to verify correct mathematical execution across all 7 phases:

# Set PYTHONPATH to the current development folder and run pytest
$env:PYTHONPATH="."; py -m pytest tests

To run GWT's production benchmark loop directly and verify memory safety, local plasticity, and dynamic chemical curves:

# Run GWT execution loop performance benchmark
$env:PYTHONPATH="."; py tests/benchmark_cognitive_engine.py
