Beyond Arithmetic: The Semantic Bottleneck in Neuro-Symbolic LLMs

Authors: Bogdan-Marius Dinu, Ciprian-Mihai Ceausescu, Cristian-Hacic Kevorchian

Accepted for publication and oral presentation at the 30th International Conference on Knowledge-Based and Intelligent Information & Engineering Systems (KES 2026), Dublin, September 2026. Read the paper (PDF)

  • Proposed a multi-agent distributed framework combining neuro-symbolic reasoning (DeepSeek-R1 8B + SymPy) with Semantic RAG to eliminate execution-level arithmetic hallucinations in edge-scale LLMs. Evaluated on benchmark subsets: GSM8K (21 problems), MATH500 (100), SVAMP (100), AIME 2025 (30).
  • Identified the Semantic Bottleneck: once arithmetic is made deterministic, natural language understanding becomes the limiting factor (92% on competition-level MATH500 against 64% on the linguistically adversarial SVAMP). On AIME 2025 the raw 8B baseline scored 0% and the 14B model 23.3%, while the same 8B model inside the pipeline reached 66.6%, showing that structural augmentation beats parameter scaling at edge scale.

Technical Skills

DevOps & Infrastructure Projects

Online Course Platform - Full-Stack Platform with CI/CD Pipeline (DevOps & Cloud) - Build Journal (PDF) - Code in private repository, available on request

Designed and shipped a production-style CI/CD pipeline for a containerized .NET 10 + Angular 19 application built on Clean Architecture. Implemented multi-stage Docker builds, a self-hosted GitHub Actions runner publishing images to a private Nexus Docker Registry, and automated SSH-based deployment to a Linux web server via docker compose. Separated dev/prod environments through Docker Compose overrides and centralized structured logging with Serilog.

Tech: Docker, Docker Compose, GitHub Actions (self-hosted), Nexus Repository, Nginx, .NET 10, ASP.NET Core, Angular 19, PostgreSQL, Linux/SSH

Jenkins CI Pipeline for a Java/Maven Application (DevOps) - GitHub

Built a declarative Jenkins pipeline (Pipeline-as-Code, Jenkinsfile versioned in SCM) running on a self-hosted Linux VM. The pipeline runs Maven unit tests, packages the artifact, builds a Docker image through the mounted host Docker socket, and pushes it to a self-hosted Nexus Docker registry. Credentials are injected at runtime via Jenkins Credentials Binding and passed with --password-stdin, never exposed in process arguments. Configured as a Multibranch Pipeline with branch-conditional stages, so feature branches run tests only while master builds and publishes; stage-level post blocks handle image cleanup and registry logout.

Tech: Jenkins, Groovy, Maven, Docker, Nexus Repository, Git, Linux/SSH

Self-Hosted Home Lab & Server Infrastructure (Infrastructure & Operations)

Operate a TrueNAS SCALE (ZFS) server hosting SMB shares, virtual machines and a stack of containerized services. Provisioned dedicated Ubuntu VMs as isolated build environments running Jenkins, a self-hosted Nexus registry and a self-hosted GitHub Actions runner. Built an alerting workflow that delivers a scheduled daily health report plus instant critical notifications to Telegram. Network services include AdGuard for DNS filtering, with remote access secured over a Tailscale (WireGuard) mesh network. Day-to-day work involves diagnosing storage, networking and permission issues across host and container boundaries.

Tech: TrueNAS SCALE/ZFS, Linux, Docker, Virtualization, Tailscale/WireGuard, AdGuard, SMB/CIFS, Bash, systemd, SSH

Software & AI Projects

Distributed Neuro-Symbolic Math Solver (AI/ML & Edge Computing) - GitHub

Built a hybrid AI pipeline combining a local DeepSeek R1 8B model with symbolic computation (SymPy) and RAG (ChromaDB) to solve mathematical problems. The edge-based system achieved 100% accuracy on GSM8K and 92% on MATH500, matching cloud-based Gemini 2.5 Flash.

Tech: Python, Ollama, SymPy, ChromaDB, RAG, Flask, LLM Orchestration, Multi-node HTTP Communication

Introduction to Robotics Repository (Embedded C++) - GitHub

Portfolio of embedded systems projects in C++ and Arduino, from analog signal processing and PWM control to Finite State Machines, hardware interrupts and sensor integration.

Malware Classification CNN (Python & AI) - GitHub

Engineered a cybersecurity tool that converts raw hexadecimal .bytes files into image representations to detect malware patterns. Trained a CNN achieving ~92% accuracy.

Tech: Python, TensorFlow, Keras, Scikit-learn, Image Processing

MarketSentiment Analyzer (Cloud & Web) - GitHub

Built a full-stack automated analysis tool that aggregates financial news. Integrated the DeepSeek R1 AI model hosted on Azure to perform sentiment analysis.

Tech: Python, Flask, Azure Cloud, PostgreSQL, LLM Integration
