Overview

This document summarizes the implementation of high-priority features from FULL_BRAIN_NODE_REQUIREMENTS.md for Full Brain mode nodes in the EvoSpikeNet distributed brain system.

Current Implementation Status: Full Brain 24-Node Configuration with Layered Architecture - PFC Layer: Multiple PFC nodes with Raft consensus (configurable count) - Sensing Layer: 3 sensor nodes (camera, microphone, environment) - Encoder Layer: 4 encoder nodes (vision, audio, text, spiking) - Inference Layer: 5 inference nodes (LM, classifier, spiking-LM, ensemble, RAG) - Decision Layer: 2 decision nodes (planner, controller) - Memory Layer: 6 memory nodes (episodic, semantic, vector-db, storage, retriever, knowledge-base, integrator) - Learning Layer: 1 trainer node - Aggregator Layer: 2 aggregator nodes (federator, result) - Management Layer: 2 management nodes (auth, monitoring)

Implemented Features

1. PFC Dedicated Parameter Settings (Multi-Modal LM Page)

Location: frontend/pages/multi_modal_lm.py

Implementation Details: - Added "Model Architecture" section to Training Parameters - Implemented "PFC Mode" checkbox for Prefrontal Cortex configuration - Automatic parameter configuration: - PFC Mode ON: d_model=256, n_heads=8, num_transformer_blocks=4 - PFC Mode OFF: d_model=64, n_heads=4, num_transformer_blocks=2 - When PFC Mode is enabled, architecture parameter inputs are automatically populated and disabled - All architecture parameters are properly passed to train_multi_modal_lm.py training script

Rationale: The PFC (Prefrontal Cortex) node is the central executive control node (Rank 0) in the Full Brain architecture. It requires a larger model architecture (d_model=256 vs default 64) to handle complex multi-modal integration and decision-making tasks.

UI Components Added: 

- mm-pfc-mode-checkbox: PFC Mode toggle
- mm-d-model-input: Model dimension (d_model)
- mm-n-heads-input: Number of attention heads
- mm-num-blocks-input: Number of transformer blocks

Backend Integration: The training command now includes: 

--d-model 256 --n-heads 8 --num-blocks 4  # When PFC mode is enabled

2. Motor System's TextLM Parameter UI (Motor Cortex Page)

Location: frontend/pages/motor_cortex.py

Implementation Details: - Added "Advanced Settings: TextLM Architecture" card section - Provides configuration for Motor nodes that use SpikingEvoTextLM - Default values aligned with requirements: - vocab_size: 1024 (action vocabulary) - d_model: 64 - n_heads: 2 - num_transformer_blocks: 2 - All parameters have appropriate validation (min/max values, step increments)

Applicable Nodes: This configuration applies to Motor Consensus nodes in the Full Brain architecture: - Motor consensus nodes (distributed consensus-based motor control)

UI Components Added: 

- motor-vocab-size-input: Vocabulary size (default: 1024)
- motor-d-model-input: Model dimension (default: 64)
- motor-n-heads-input: Number of attention heads (default: 2)
- motor-num-blocks-input: Number of transformer blocks (default: 2)

Note: The current motor training script (evo_motor_master.py) uses a different RL-based approach. Full integration would require creating or updating a motor training script that accepts these TextLM parameters. The UI is ready for when that integration is completed.

3. Architecture Parameter Visualization (Spiking LM Page)

Location: frontend/pages/spiking_lm.py

Implementation Details: - Added "Model Architecture" section prominently in the Training Parameters area - Provides clear, configurable inputs for key architecture parameters - Default values optimized for language processing: - d_model: 128 - n_heads: 4 - num_transformer_blocks: 2 - Parameters are properly passed to train_spiking_evospikenet_lm.py

Applicable Nodes: This configuration applies to Inference Layer nodes in the Full Brain architecture: - lm-inference-0 (language model inference) - spiking-lm-0 (spiking language model) - ensemble-inference-0 (ensemble methods) - rag-inference-0 (retrieval-augmented generation)

UI Components Added: 

- slm-d-model-input: Model dimension (default: 128)
- slm-n-heads-input: Number of attention heads (default: 4)
- slm-num-transformer-blocks-input: Number of transformer blocks (default: 2)

Backend Integration: The training command now includes: 

--d-model 128 --n-heads 4 --num-blocks 2

4. LLM Training UI Enhancement (Vision/Audio Encoder Pages)

Location: frontend/pages/vision_encoder.py, frontend/pages/audio_encoder.py

Implementation Details: - Added "API Training (New)" tab to both Vision and Audio Encoder pages - Integrated with the LLM Training System API for distributed model training - Provides category selection dropdown (LangText, Vision, Audio, MultiModal) - Dynamic display of selected model type and category - Configurable training parameters (epochs, batch size, learning rate, run name) - GPU training support toggle - Real-time training status and output display

Applicable Nodes: This enhancement applies to Sensing and Encoder Layer nodes in distributed brain: - Sensing Layer: camera-sensor-0, microphone-sensor-0, environment-sensor-0 - Encoder Layer: vision-encoder-0, audio-encoder-0, text-encoder-0, spiking-encoder-0

Rationale: The LLM Training UI enhancement ensures that all training screens support node-matching parameters and display model types/categories dynamically. This is crucial for proper integration with the distributed brain system where different nodes handle different modalities (Vision/Audio) and must be configured with appropriate model categories.

Conclusion

This implementation provides a solid foundation for configuring Full Brain mode nodes with appropriate architecture parameters. The UI is intuitive, well-validated, and properly integrated with existing training scripts. The changes are minimal, focused, and follow existing code patterns in the repository.
