HΔHIDDEN DELTA

AI RESEARCH & SECURITY

The difference
is in the delta.

We investigate how intelligent systems learn, decide,
and behave — and what it takes to make them reliable.

01 / RESEARCH & PRACTICE

From first principles
to real systems.

Hidden Delta brings together fundamental AI research, security analysis, and the engineering needed to put ideas to the test.

Fundamental AI

Learning, optimization, and decision-making. We explore reinforcement learning, symbolic methods, and interpretable models, with particular interest in continuous and dynamic environments.

Reinforcement learning · Symbolic regression · Optimal control

AI & cybersecurity

Understanding how systems fail is part of understanding how they work. Our focus spans the security of AI systems and the use of AI in security research, including adversarial evaluation, software analysis, and trust boundaries.

Adversarial testing · Model robustness · Software & API security

Applied research
& engineering

Turning open questions into experiments and working systems. We connect mathematical modeling, simulation, and data analysis with practical software and research infrastructure.

Numerical optimization · Simulation · Research software

02 / OUR APPROACH

Question the assumptions.
Follow the evidence.

A useful result starts with a well-posed question. We work from explicit assumptions, test against meaningful baselines, and examine where a method breaks down.

Understand

Define the problem, the objective, and the limits of what is known.

Investigate

Build models, run experiments, and test competing explanations.

Make it useful

Translate the findings into methods, software, and clear technical decisions.

Our research foundations include symbolic regression for reinforcement learning in continuous spaces — connecting interpretable mathematical expressions with sequential decision-making.
