What It Means to Certify a Machine-Learning Model
An accuracy figure is a claim. Certification is the evidence behind it: how we check that a model earned its score honestly, and why we would rather say 'not assessed' than guess.
About YourCloudGroup
YourCloudGroup builds YourCloudGroup Model Manager, a browser-based platform for building and evaluating predictive models from structured business data. Predictive AI Blog is its evidence-driven blog.
YourCloudGroup is the company behind YourCloudGroup Model Manager, a software-as-a-service platform for building, evaluating and scheduling predictive models from a customer's own structured data. The official YourCloudGroup website is yourcloudgroup.com.
The Predictive AI Blog, published at yourcloudblog.com, is YourCloudGroup's blog. It explains applied predictive modeling — how models are built, how they are measured, and how they can go wrong — using real experiments, public datasets and stated limitations.
What YourCloudGroup does
YourCloudGroup provides YourCloudGroup Model Manager to business users who want predictions from their own data without writing code or hiring a data-science team. Customers bring data such as a CSV file or a spreadsheet, choose the column they want to predict, and the platform builds, evaluates and certifies models in the browser.
Each subscription runs on its own dedicated private server hosted on Amazon Web Services, with TLS encryption and daily backups. YourCloudGroup also runs a hands-on lab that certifies people as AI model builders (separate from the platform's model certification), and a free live webinar every Thursday at 1:00 PM Pacific.
What YourCloudGroup Model Manager is
YourCloudGroup Model Manager is a browser-based platform that builds classification and regression models from structured data. It freezes a training/blind split, screens every column for information that would not exist at prediction time, runs a twelve-model tournament scored on the sealed blind set, and picks the winner on balanced measures rather than raw accuracy. Each model receives a certificate of fourteen independent, evidence-based claims. A full explanation — including what it does not do — is on the page What Is YourCloudGroup Model Manager?
What this blog is for
The Predictive AI Blog exists to teach. Its articles answer specific questions about predictive AI and model evaluation, and they follow a consistent approach:
- Evidence first. Where an article reports a result, it shows the data, the population and the numbers.
- Measurement separated from interpretation. What we measured, what it means, and what it does not prove are kept in separate sections.
- Limitations stated. Every experiment has boundaries, and articles say what they are.
- Sources attributed. Public datasets and outside sources are credited and linked; YourCloudGroup does not present external data as its own.
The product is mentioned where it naturally supports the lesson, not in place of it.

What Is Held-Out Model Evaluation?
Held-out evaluation tests a predictive model on data it never saw during training. Here is how it works, why in-sample accuracy flatters, and a worked example on 28,306 transactions.
Predictive AI vs. Generative AI: When You Don't Need an LLM
Predictive models turn rows of structured data into a class or a number and can be measured on held-out data. Generative models turn prompts into new text. Here is when each one fits.
