Neuro-Harmonic Graph Engine — iterative harmonic resonance ML architecture

Neuro-Harmonic Graph Engine (NHGE)

#IDEA INITIATED BY H.A.Mwala (Full name HEKIMA A. MWALA) #TANZANIAN A novel machine learning architecture that replaces transformer parallelism with iterative harmonic resonance over a dynamic graph structure.

Key Idea

Transformers compute attention in one parallel pass over all tokens simultaneously. NHGE iterates — tokens are graph nodes that resonate with each other, updating their states step by step until the graph reaches harmonic convergence.

Property	Transformer	NHGE
Processing	Parallel attention	Iterative harmonic resonance
Depth	Fixed layers	Dynamic (stops at convergence)
Edge weights	Attention scores	Similarity × phase coherence
Memory	O(N²) attention matrix	O(N²) but iterative, not stacked
Simple inputs	Same cost as complex	Converges faster → cheaper

Quick start

from nhge_model     import nhge_small
from nhge_tokenizer import NHGETokenizer
from nhge_inference import NHGEInference

# 1. Build tokenizer
tok = NHGETokenizer(mode="word")
tok.build_vocab(your_texts, min_freq=2)

# 2. Build model
model = nhge_small(vocab_size=tok.vocab_size, num_classes=2)

# 3. Inference
inf = NHGEInference(model, tok, device="cuda")
results = inf.classify(["Your input text here"], label_names=["neg", "pos"])

# 4. Generate
text = inf.generate("The harmonic graph", max_new_tokens=50)

Training

from nhge_trainer import NHGETrainer, TokenDataset
from torch.utils.data import DataLoader

dataset = TokenDataset(encoded_tokens, labels=class_labels, max_len=128)
loader  = DataLoader(dataset, batch_size=32, shuffle=True)

trainer = NHGETrainer(model, loader, val_loader=val_loader,
                      task="cls", lr=3e-4, device="cuda")
history = trainer.train(epochs=20)

Theory

The harmonic edge weight combines two signals:

1. Semantic similarity — scaled dot product of Q and K projections
2. Phase coherence — cos(θ_i − θ_j) between learned phase angles

Nodes in phase amplify each other's signals. Out-of-phase nodes cancel. This mimics oscillatory dynamics in biological neural networks, where synchronised firing encodes binding of related concepts.

The phase angles are updated each iteration via a damped gradient:

θ ← θ + α · tanh(W·h) · π

This allows the network to "tune" its resonance frequencies as information propagates — a form of learned synchronisation.
