Full Brain Mode - Node Requirements & UI Coverage Analysis

[!NOTE] For the latest implementation status, please refer to Functional Implementation Status (Remaining Functionality).

Purpose and use of this document

  • Purpose: List the requirements and UI support status of each node in Full Brain mode, and quickly identify gaps in implementation/testing.
  • Target audience: Frontend/backend implementers, QA, PM.
  • First reading order: Overview → Implementation status list → Requirements/gaps by node.
  • Related links: Distributed brain script in examples/run_zenoh_distributed_brain.py, PFC/Zenoh/Executive details in implementation/PFC_ZENOH_EXECUTIVE.md.

  • Implementation notes (artifacts): See docs/implementation/ARTIFACT_MANIFESTS.md for output artifacts for each node. artifact_manifest.json and CLI flag specifications (--artifact-name, --node-type, --precision, --quantize, --privacy-level) are described.

Overview

Full Brain mode uses a 24-node configuration in a Zenoh-based distributed brain system. The model, parameters, and current UI support status required for each node are shown below.

Current implementation configuration: - PFC Layer: Execution control node (cluster configuration possible) - Sensing Layer: Sensor data collection nodes (cameras, microphones, environmental sensors) - Encoder Layer: Data encoding nodes (visual, audio, text, spiking) - Inference Layer: Inference processing nodes (language model, classification, spiking LM, ensemble, RAG) - Memory Layer: Memory management node (episodic, semantic, integrated) - Motor Layer: Motor control node (autonomous consensus based) - Management Layer: Monitoring/authentication node


Implementation status list

Status Legend

  • 🟢 Fully implemented: All necessary functions have been implemented, all parameters can be set on the UI
  • 🟡 Partial implementation: Basic functionality works, but dedicated parameters and subtype settings are missing.
  • 🔴 Not implemented: Lack of setting functions in UI, manual implementation required *Exception: PFC mode switching callback has already been implemented and unit tested. The "lack of UI testing" in the documentation is an exaggeration.
  • N/A: No applicable function

Download function details

AutoModelSelector operation flow

  1. Node type determination: module_typebase_module conversion
  2. Model class selection: Appropriate model class selection based on task_type
  3. API download: If there is a session ID, download the model file from the API
  4. Fallback initialization: Initialize with default parameters when API download fails
  5. Ultimate Fallback: Use SimpleLIFNode when unknown node type

Supported Task Types

  • pfc: Multimodal language model (for PFC only)
  • lang-main: Text language model (general language processing)
  • visual: Visual encoder (image processing)
  • audio: Audio encoder (sound processing)
  • motor: Motion control model (text-based control)
  • SimpleLIFNode: General purpose spiking neural network (Fallback)

Download file naming convention```python

weights_name = { 'pfc': "multi_modal_lm.pth", 'lang-main': "spiking_lm.pth", 'visual': "vision_encoder.pth", 'audio': "audio_encoder.pth", 'motor': "spiking_lm.pth" }

### Robust implementation
- ✅ **100% Compatible**: All 24 nodes support model download function
- ✅ **Multiple Fallback**: API failure → Default initialization → SimpleLIFNode
- ✅ **Automatic detection**: Automatically selects the appropriate model based on the node type
- ✅ **Safety**: Includes heartbeat monitoring during downloading

### Check the operation of the download program

Check the operation of each data download program through source code analysis:

#### ✅ WikipediaLoader
```python
# Implementation: using wikipediaapi
self.wiki_api = wikipediaapi.Wikipedia(language=self.lang, user_agent='EvoSpikeNet/1.0')
page = self.wiki_api.page(title)
return page.text  # cleaned text

✅ AozoraBunkoLoader

# Implementation: requests + BeautifulSoup usage
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
main_text = soup.find('div', class_='main_text')
return main_text.get_text()  # Ruby removed

✅ HuggingFace Datasets

# Implementation: using datasets library
from datasets import load_dataset
dataset = load_dataset(dataset_name, subset, split=split)

✅ Torchvision Datasets

# Implementation: using torchvision.datasets
train_dataset = datasets.MNIST(root='./data', train=True, download=True, transform=transform)

✅ Librosa Audio Loading

# Implementation: using librosa
audio, sr = librosa.load(sample['path'], sr=16000)
mfcc = librosa.feature.mfcc(y=audio, sr=sr, n_mfcc=13)

Model evaluation and saving

Evaluation method

Each training script evaluates: - Language model: Perplexity calculation - Vision model: Classification accuracy - Audio model: Classification accuracy - Multimodal: Caption generation quality

Artifacts saved

  • model.pth: Model weights
  • config.json: Model settings
  • tokenizer.pkl: Tokenizer (language model)
  • training_log.json: Learning history

Integration with distributed learning

API cooperation

Trained models are automatically uploaded to the API and made available to distributed brain nodes.

# After training is completed, upload to API
python -c "

<!-- from evospikenet.sdk import EvoSpikeNetAPIClient -->
client = EvoSpikeNetAPIClient()
client.upload_model('saved_models/pfc_model', 'pfc', 'multi_modal_lm')
"

AutoModelSelector cooperation

Uploaded models will be automatically downloaded and used through AutoModelSelector.

Notes

Computational resources

  • PFC model: High memory usage (GPU 8GB or more recommended)
  • Language model: Long-term learning (several hours to days)
  • Vision/Audio: Relatively lightweight (GPU 4GB or more)

Data quality

  • The quality of training data greatly affects model performance
  • Proper preprocessing and normalization are important
  • Ensure sufficient amount of data

Version compatibility

  • Retraining required when model architecture changes
  • Check API version compatibility

This training method allows us to generate high-quality LLMs for all 24 nodes.
