integrating BNNs, Transformers, and hierarchical knowledge nodes.

What is Xctopus?

α Alpha

[Research Framework in Alpha] Xctopus is a hierarchical continual learning framework designed to address one of the most critical challenges in machine learning: catastrophic forgetting. Unlike traditional monolithic systems that overwrite prior knowledge when learning new information, Xctopus organizes learning into a dynamic hierarchy of modular Knowledge Nodes, orchestrated through probabilistic control mechanisms and evolving incrementally based on the structure and distribution of incoming data.

Core System Architecture

Xctopus is structured into fundamental components that work in synergy to enable continuous learning:

Global Bayesian Orchestrator

The central Filter Bayesian that processes initial inputs and manages probabilistic routing. It estimates domain probabilities, directs information to appropriate Knowledge Nodes, and triggers creation of new nodes when evidence supports novel subdomains.

Autonomous Knowledge Nodes

Specialized local modules containing PEFT (LoRA) Adapters and Local Filters for domain-specific adaptation. Each node processes inputs through efficient parameter tuning and local belief updates, generating outputs including ID, centroid, mass, and variance.

Transformer Base

The foundational language model that provides core encoding capabilities. Interacts with the KN Repository to access and integrate knowledge from specialized nodes, serving as the primary computational engine for natural language understanding.

KN Repository

Central storage for Knowledge Node statistics and outputs. Maintains ID, centroid, mass, variance, and PEFT weights for all nodes, enabling efficient retrieval and integration by the Transformer Base component.

Processing Line

Manages the creation of new Knowledge Nodes when evidence supports novel subdomains. Initializes parameters from global priors and ensures seamless integration with existing architecture.

Post-processing

Includes Quality Evaluator and Feedback Dispatcher for system optimization. Evaluates output quality and dispatches feedback loops to update mass and variance in the Orchestrator, ensuring continuous improvement.

Operational Control Layer

The system's engine that orchestrates the complete processing pipeline. Coordinates intelligent routing, ensures full traceability, and enables modular scaling while preserving architectural stability through continuous feedback loops.
