KEM®: Explainable AI
built for complex data.
Developed at the CNRS, KEM® produces transparent, auditable, rule-based results. Unlike black-box machine learning, every finding can be scrutinised by your teams and by regulators.
Explainable by design
Every insight is a logical, rule-association-based result: transparent and fully auditable. Not a probability, a certainty your teams can act on.
Built for heterogeneous data
Ariana ingests and unifies multiple sources in different formats over extended time periods. Heterogeneity is a feature, not a problem.
Weak signal detection
The platform identifies rare but strong signals in time series and cross-sectional data, complementing standard statistical analyses.
Prioritises actionability
Data and results are accessible via a flexible, intuitive dashboard - designed for decision-makers, not just data scientists.
Turning heterogenous data into decision-making tools.
Potential applications to the ministry's challenges - each grounded in the same KEM® technology, adapted to France's transport infrastructure data landscape.
Assess the real effect of a policy (80 km/h speed limit, low-emission zones, free public transport) by isolating its impact from seasonal trends and external shocks, with causal rigour (Hill criteria).
Measuring the impact of public policies
Cross-reference traffic, weather, infrastructure condition and incident history to identify at - risk zones before an accident occurs - moving from reactive to predictive road safety.
Early detection of incident risk
Aggregate and harmonise PRM data (lifts, pathways, equipment) scattered across SNCF, RATP and local authorities - a 2026 ART priority and National Access Point requirement.
Consolidation of accessibility data
Query inspection reports, circulars and incident feedback in natural language. Immediate ROI, limited scope, zero IT overhaul - the fastest path to value from existing data assets.

THE CHALLENGE
-
6 distinct databases: hospitals, outpatient visits, mortality, notifiable diseases, births, vaccines
-
Incompatible formats, different operators
-
8 years without an official scientific response
WHAT ARIANA DID
-
Consolidated all data sources into a single Knowledge Base
-
Interrupted Time Series analysis with a 20M-person control group
-
Breakpoint detection and S-ARIMA seasonality filtering
THE OUTCOME
-
Direct toxic impact: unmeasurable (evidence of absence)
-
Health signal identified 2 years after the event
-
Robust scientific answer where epidemiologists had failed for 8 years
