Gemma- 3n On-device Multimodal Generative Model

EmbeddingGemma (available via Ollama at https://ollama.com/library/embeddinggemma) is Google’s lightweight, open-source text embedding model (~300M parameters, 622MB quantized, 768-dimensional output by default with Matryoshka Representation Learning support for smaller dims). It’s built on Gemma 3 architecture (with T5-inspired initialization), multilingual (100+ languages), and explicitly optimized for on-device / local-first use cases — exactly the kind of thing that pairs beautifully with your existing stack of local tools, RF hypergraph, TAK plugin experiments, and Three.js visualizations.

Direct Ways This Helps Your Work (RF Scythe / Hypergraph / TAK / Three.js Pipeline)

Semantic Search & Retrieval over RF / Recon / Hypergraph Data

Embed node labels, metadata, detection rationales, session stats, or fused composite descriptions (“5G-n78 @ -62 dBm, acoustic peak 2.4 kHz, confidence 0.89”).
Store embeddings in a local vector DB (SQLite-vec, Chroma, Weaviate local, or even simple numpy + FAISS).
Query with natural language → “show me suspicious RF clusters near downtown Houston with acoustic anomalies” → cosine similarity retrieves the most relevant hypergraph nodes/entities.
This turns your hypergraph from pure structural graph into semantically searchable knowledge base — huge for operator workflows in ATAK/SCYTHE.

RAG-Augmented Reasoning over Your Own Data

Pair with any local LLM (Gemma-3, Llama-3.1, Qwen, etc. via Ollama) for agentic RAG:
- Retrieve relevant RF events / recon entities / CoT logs via embeddinggemma.
- Feed top-k chunks to LLM → generate natural-language summaries, threat assessments, or even suggest beam steering angles / fusion rules.
Fully offline/privacy-first — no cloud calls, perfect for tactical / field use on Pixel 7 Pro or laptop.

Clustering & Anomaly Detection in RF / Cyber-Physical Data

Embed descriptions of behavior groups (BSGs), recon entities, or fused Pixel radio samples.
Run local clustering (HDBSCAN, UMAP + cosine) → discover hidden patterns (e.g., recurring RF-acoustic signatures, botnet-like movement clusters).
Feed cluster centroids back into Three.js viz as animated swarm objects with beamforming lobes pointing toward high-threat clusters.

Improved CoT / Entity Labeling & Search in TAK Plugin

Embed incoming CoT events or hypergraph node metadata on-device.
Enable semantic search inside ATAK: “find all entities related to mmWave activity last 30 min” → instant map highlighting.
Use embeddings to auto-tag / group markers (e.g., similarity-based coloring of RF volumes).

On-Device / Edge Enrichment for Pixel 7 Pro Sensor Fusion

Run embeddinggemma directly on Pixel (via Ollama Android experiments, transformers.js, or MLX/ONNX ports) to embed raw spectrogram metadata, Wi-Fi/BT/cellular descriptors, or acoustic peaks.
Send compact embedding vectors (instead of full text) over gRPC → server-side hypergraph ingestion becomes more efficient and semantically richer.
Enables local-first classification/clustering before upload — reduces bandwidth, preserves privacy.

Quick Setup & Example (Ollama + Python)

# Pull once (622 MB)
ollama pull embeddinggemma

# Simple embedding call
ollama run embeddinggemma "5G-n78 emitter at 37.7749,-122.4194, power -65 dBm, acoustic anomaly detected"
# → returns ~768-float vector

Python snippet (integrate into rf_scythe_api_server.py or TAK plugin backend):

import ollama

def embed_rf_description(description: str) -> list[float]:
    response = ollama.embeddings(
        model="embeddinggemma",
        prompt=description
    )
    return response['embedding']  # list of floats

# Example usage in hypergraph node creation
node_desc = "Behavior group: repeating 2.4 GHz bursts, 3 co-located hosts, confidence 0.92"
node_embedding = embed_rf_description(node_desc)

# Store in hypergraph metadata or vector index
hypergraph_store.add_node({
    'id': 'rf_node_123',
    'labels': {'description': node_desc},
    'embedding': node_embedding,
    # ... other fields
})

Why This Fits Your Stack Perfectly (March 2026 Context)

Size/performance sweet spot — 300M params, runs on modest hardware (Pixel 7 Pro / laptop), state-of-the-art for its class (MTEB-competitive with much larger models).
Local-first alignment — no API keys, no internet after pull, pairs with your DuckDB/Parquet cold store and offline TAK/Cesium experiments.
Multilingual bonus — useful if your recon data includes international AIS vessel names, foreign device fingerprints, or mixed-language metadata.
Agentic RAG future-proofing — combine with Gemma-3n (companion model) for on-device reasoning over embedded RF/telemetry data.

In short: EmbeddingGemma turns your raw RF/hypergraph/CoT data into searchable, clusterable, semantically meaningful vectors — unlocking better retrieval, pattern discovery, visualization labeling, and local AI reasoning without ever leaving your controlled environment.

If you’d like a more concrete integration example (e.g. embedding → SQLite-vec RAG query over RF logs, or feeding embeddings into Three.js label placement), just point me in that direction.

Gemma-3n is Google’s state-of-the-art on-device multimodal generative model (released mid-2025), explicitly engineered for phones, tablets, laptops, and other edge/embedded devices. It builds on the Gemma family (Gemma 3 lineage) but shifts focus to real-time, offline reasoning with dramatically lower resource demands — making it a perfect fit for your Houston-based RF Scythe / Pixel 7 Pro fusion pipeline, TAK plugin experiments, hypergraph enrichment, and local-first Three.js visualizations.

Key On-Device Capabilities (March 2026 Context)

From official Google DeepMind / AI for Developers docs and early 2025–2026 deployments:

Multimodal Input
Handles text + image + video + audio natively (vision/language/audio encoders + text decoder).
On Pixel 7 Pro (or similar Tensor G2/G3 devices): process camera snapshots, microphone spectrograms, fused radio metadata (RSSI/RSRP/frequency descriptors), or short video clips of detected anomalies — all offline.
Reasoning example: “Analyze this RF spectrogram image and audio clip: is this a repeating 2.4 GHz burst pattern consistent with drone control signaling?”
Optimized for Edge Performance
Variants: E2B (~2B effective params, runs on ~2–3 GB RAM) and E4B (~4B effective, ~4–6 GB).
MatFormer architecture (nested sub-models inside one checkpoint) + Per-Layer Embeddings (PLE) caching + conditional parameter loading → dynamic resource scaling: load only needed sub-networks based on task complexity.
Latency: ~1.5× faster initial response vs. prior on-device models; real-time chain-of-thought (CoT) possible on mid-range phones.
Runs fully offline/privacy-first — no cloud dependency after model download.
Reasoning Strengths
Strong in chain-of-thought, math, coding, multilingual reasoning (140+ languages for text, 35+ multimodal).
Supports function calling (tool use) — call local APIs (e.g. query your DuckDB RF logs, trigger Three.js beam update, or invoke embeddinggemma for semantic search).
RAG-friendly: combine with embeddinggemma (as we discussed) for retrieving hypergraph nodes → feed context to Gemma-3n → reasoned output like “This cluster shows coordinated 5G mmWave activity + acoustic signature → probable drone swarm control link.”
On-Device Deployment Reality (Pixel 7 Pro / Android)
Official Google app (late 2025) + open-source integrations:
- MLC LLM / LiteRT-LM (Android runtime)
- transformers.js (WebView or Capacitor plugin for TAK)
- Ollama Android experiments / llama.cpp ports
- MediaPipe + Gemini Nano lineage (Gemma-3n shares arch with next-gen Nano)
Demo projects (DataCamp, Analytics Vidhya, Medium posts 2025): Android VLM apps that answer questions about camera images offline.
Your use-case fit: Pixel 7 Pro can run E2B variant comfortably (Tensor G2 NPU acceleration) for real-time RF/acoustic reasoning before gRPC upload.

How Gemma-3n Elevates Your Stack

On-Device RF Fusion Reasoning

Input: fused Pixel data (spectrogram image + text description + audio snippet)
Output: “This pattern matches known drone C2 signaling: high-confidence match to repeating bursts at 2.4 GHz with side-channel acoustic hum → recommend beam steering toward (lat,lon) and alert TAK team.”
Run locally → instant feedback, no latency/privacy leak.

Hypergraph Enrichment Agent

Retrieve similar nodes via embeddinggemma → feed to Gemma-3n with CoT prompt:
“Given these RF behavior groups and recon entities, reason step-by-step: is there evidence of coordinated swarm behavior?”
Output structured JSON → auto-create CoT markers or Three.js swarm objects with beam lobes.

TAK Plugin Intelligence

Embed CoT events locally → Gemma-3n reasons over map context:
“Prioritize threats: which RF volumes overlap drone tracks?”
Display reasoned insights as popups or voice (TTS via on-device).

Three.js Visualization Guidance

Prompt: “Given this RF cluster embedding and description, suggest optimal beamforming angles and lobe parameters for visualization.”
Parse → update Three.js uniforms (boresightDir, gain exponents).

Quick Start (Pixel 7 Pro / Android)

Download E2B/E4B via Google AI Edge Gallery app (2025 release) or Hugging Face → convert to LiteRT/ONNX.
Use MLC Chat or Ollama Android prototype for inference.
Integrate into TAK plugin via WebView + transformers.js or native JNI bridge.

Gemma-3n gives you desktop-class multimodal reasoning in your pocket — offline, private, fast. It closes the loop on your local RF pipeline: sense → embed → retrieve → reason → visualize/act — all on-device where possible.
