# ML & AI R&D prototypes

> Prototypes and experiments that test whether a machine learning or reinforcement learning idea works — in simulation or on offline data, with results you can rerun.

This is research engineering for ideas that are not yet features. The idea becomes a measurable question, and a prototype is built in Python and PyTorch, then trained and evaluated in a simulated or offline environment, isolated from the systems you run.

It fits when building is expensive and the answer is uncertain: a reinforcement learning or prediction idea, a model that worked once and needs checking, or two approaches to compare. You receive measured results and a recommendation — a proof of concept, not a production system.

Outcome: Evidence to build, rework or stop, from experiments you can rerun.

## Typical needs

- A machine learning idea that needs evidence before a full build
- Model results that change between runs and can’t be reproduced
- A question to test in simulation or on offline data, away from live systems

## What you receive

- A runnable prototype in Python, with its training environment or dataset
- An evaluation harness that compares the model with baselines over fixed seeds
- A report of results and limits, with a recommendation: build, rework or stop

## How the work runs.

1. Frame a measurable question: The idea is written as a question an experiment can answer: the metric, the baselines it has to beat and the result that would mean stopping.
2. Isolate the environment: A simulated environment or an offline dataset is set up apart from production, so runs are safe to repeat and nothing touches the systems in use.
3. Train with fixed seeds: The model is prototyped in PyTorch and trained next to simple baselines over several fixed seeds, with pinned dependencies and tests in CI.
4. Report and recommend: Results are written up with their spread across seeds and what they do not establish, followed by a recommendation: build, rework or stop.

## From the founder’s research

Ariaska RL is the founder’s research in isolated, simulated environments, not client work. Its final local suite reports 3,318 passing tests; a synthetic evaluation over three seeds reran byte-identically.

## About this service.

### How is this different from applied AI & business automation?

Applied AI puts language models into a working process, with a person approving the output. This service answers an earlier question: whether a model or learning approach works at all, in simulation or on offline data. If it does, the prototype and its report become the starting point for a production build.

### Do experiments need access to our live systems?

No. Experiments run in a simulated environment or on offline data agreed with you, apart from production. In Ariaska RL, the founder’s research, the CI suite likewise runs offline, with network access and tool execution denied.

### What if the results show the idea doesn’t work?

Then that is the answer — written down with the numbers behind it, and reached before the cost of a full build. The report states what the experiment did and did not establish, and whether a different question is worth testing next.
