Lab

l13v is a small AI research lab performing applied research across agent harnessing, ontology-based query systems, computer vision, and nonlinear signal processing — the convergence of a maths and physics foundation, complexity science (emergence, chaos, nonlinear dynamics), vision and control systems, and a decade of high-precision software engineering.

Research Areas

Semantic-Surface Evaluation

Independent evaluation of semantic query layers against raw-backend ground truth: every claim executed twice, four failure classes, an S1–S4 severity scale, and a landing pad for the correctness reports filed upstream.

Agent Harnessing

Frameworks and methodologies for human–agent collaboration in software engineering: multi-phase development workflows, engineering-standards enforcement via agents, and long-horizon memory and retrieval for agent sessions, with evaluation of agent reliability.

Ontology & Query Systems

Domain-agnostic ontology inference from heterogeneous structured and unstructured data sources, natural-language to structured-query translation, and benchmark-driven evaluation of query-generation quality.

Computer Vision for Sports Analytics

AI-driven sports-video understanding: player and ball tracking, event detection, and fan-experience enhancement.

Signal Processing & Nonlinear Dynamics

Analysis of nonlinear and chaotic systems via higher-order statistics and nonlinear time-series methods. Originated in partial-discharge research in high-voltage insulation; the methods recur across signal-processing problems.

Projects

Agent-Harnessing Toolkit

A family of frameworks for AI-augmented development: a multi-phase engineering methodology for human–agent collaboration, a mechanism for authoring and enforcing engineering standards through agents, and an advanced memory-retrieval layer for long-running agent sessions.

Sports Video Analytics

Tracking systems for automated sports-video analysis: player and ball tracking, event detection, and game understanding. Ongoing research into AI-driven sports-video understanding and fan-experience enhancement.

Principles

  • Measure before you optimize — every claim about a system is backed by a benchmark, not an impression.
  • Show the reasoning — the method matters as much as the result; if it is not reproducible, it is not done.
  • The instrument is part of the claim — calibration, provenance, and error bars are first-class, not afterthoughts.
