Does it actually beat the baseline?

I'm Vinayak Bhadani, a demand planner in Dubai who builds the models he plans with. I run independent, out-of-sample tests on AI and statistical forecasting — the tests vendors don't run and consultancies don't publish — and I tell you whether the system beats a seasonal naive baseline. Including when it doesn't.

Exhibit A

Evidence I publish what fails

I tested my own trading platform properly. It didn't work.

AlphaOS is an agentic multi-market trading system I built and deployed — four research agents, an AI signal pipeline, a full backtesting engine. Then I ran walk-forward validation on it and published the result on my own site: the strategies do not beat buy-and-hold out-of-sample. The in-sample numbers looked good. The out-of-sample numbers did not. I said so publicly, in writing, with the code.

Equities — Sharpe
+0.27→−0.10
Crypto — Sharpe
+0.09→−0.21
What did hold
−50% drawdown

In-sample to out-of-sample, both asset classes. The drawdown reduction of roughly half was the one result that survived every variant — so that's what I reported as real. This is the standard I hold your forecasting vendor to, and it's the standard I hold my own work to first.

Engagements

Three ways to work together. All of them start with the same call: what number are you trusting, and who produced it?

Core engagement

AI Forecast Audit

An independent verdict on whether your current or proposed forecasting system earns its licence fee. Most useful when you're mid-way through a vendor selection and the numbers in the deck came from the people selling you the software.

  • Walk-forward validation on your own demand history
  • Scored against naive and seasonal naive baselines
  • Forecast value-add by category and horizon
  • Written verdict, full method and code handed over
2–3 weeks · scoped to your SKU count and history depth
Ongoing

Validation retainer

I sit beside you through vendor selection and the first quarters of go-live, and hold the vendor to the accuracy number they promised in the pitch. The only person in the room with no incentive to tell you it's going well.

  • Independent scoring each planning cycle
  • Vendor claim vs. measured reality, in writing
  • S&OP cadence run as a decision forum
  • Escalation memos your board can read
Monthly · minimum three months
Build

Planning system build

When the audit says the answer is to build rather than buy. I've shipped the forecasting models, the ETL, and the dashboards — every tool on this site is mine, with public commit history.

  • Python forecasting with validated baselines
  • ERP and Shopify ETL pipelines
  • Power BI and web planning dashboards
  • Deployed on live data, not a prototype

Why an independent

Everyone in this market has a reason to tell you the forecast is working. Here's who can't give you a straight answer, and why.

Who you'd normally askWhy the answer is compromised
The software vendorStructurally cannot publish a test showing their own product loses to a seasonal naive baseline.
The implementation partnerEarns on the rollout. A negative verdict kills their own pipeline before it starts.
Your data science teamUsually benchmarks against a moving average or against nothing, because a planning baseline is a planning concept, not an ML one.
Your plannersKnow exactly what the right baseline is. Rarely have the harness to test against it.
An independent operatorNo licence to sell, no rollout to win. Paid for the answer, not for the answer being yes.

The method

Nothing proprietary and nothing hidden. You get the code, so you can re-run it after I leave.

Reconstruct the history

Clean demand history, not shipment history. Promotions, stockouts and Ramadan shifts separated out before anything gets scored.

Set the honest baseline

Naive and seasonal naive, computed on your data. If a model can't beat these, nothing else about it matters.

Walk it forward

Roll the model through time, forecasting only from what it could have known at each point. No hindsight, no leakage, no in-sample flattery.

Report the value-add

Accuracy, bias and forecast value-add by category and horizon — including the segments where the model loses. Especially those.

Start the conversation

Tell me what system you're running or considering, how much history you have, and what made you doubt the numbers. If an audit isn't the right answer, I'll say that too.
