13-Model Ensemble NLP & Text Forensics

A specialized multilingual NLP processing pipeline operating through high-speed FastAPI services to detect fraudulent patterns, toxic content, and intent manipulation in real time.

  • Multilingual Intent Classification: Dedicated model layers adapted to distinct language families (Slavic, Germanic, Romance, Baltic) for accurate contextual parsing.
  • 3-Tier Engine Logic: Parallel processing combining Word-Level (Semantic), Char-Level (Symbolic/Leetspeak), and Context-Level (Behavioral) analysis.
  • Priority Safety Core: Isolated high-alert pipeline dedicated to detecting Human Trafficking & Exploitation patterns.
  • Automated Risk Calibration: Quantile gate ($q = 0.98$) filtering normal traffic and routing the top $2\%$ tail directly to the Policy Layer.

System Policy Layer & Production Standards

Engineered under the principle that structure and policy come first: production-first deployment, explainable AI logic, and strict reproducibility without "magic".

  • Policy-Layer Authority: Business and safety logic resides strictly in the policy layer, ensuring complete oversight over model outputs and access control.
  • Explainability & Auditability: Every match and moderation score carries deterministic diagnostic telemetry for full system explainability.
  • Distributed Infrastructure: High-reliability node architecture deployed on Hetzner environments with isolated database workers.
  • Mobile Edge Processing: High-speed Dart/Flutter mobile applications handling local camera frame alignment and secure payload hashing.

End-to-End Execution Pipeline

1. Client Ingestion & Edge Filter

Mobile (Dart/Flutter) or Web clients validate input payloads locally before transmitting requests to the Ruby on Rails primary routing layer.

2. Asynchronous MLOps Dispatch

Rails dispatches tasks to isolated FastAPI worker pools hosting CNN biometrics engines and the 13-model NLP ensemble for parallel inference.

3. Policy Gate & Vector Search

Inference results are validated by the Policy Layer. Biometric vector search is executed, raw images are purged, and verified results are returned.
