# Machine Learning for Automotive & Mobility

> Vehicle classification · valuation · maintenance · fleet decisions

## Domain Overview
Automotive and mobility decisions use specifications, operating cost, usage, condition, sensor summaries, and service history. Tabular models turn those attributes into estimates for appraisal, fleet selection, maintenance, and quality review.

Classification fits a category such as vehicle type, acceptability tier, or inspection outcome. Regression fits a number such as price, remaining life, repair duration, energy use, or resale value. Images and raw sensor streams may need specialist models. Teams can still combine their extracted measurements with business data in a table.

## Business Decision Use Cases
| Decision Problem | Formulation & Operational Impact |
| :--- | :--- |
| **Vehicle classification** | Categorize a vehicle, component, inspection, or operating state from specifications and measured attributes. |
| **Pricing and appraisal** | Estimate acquisition, resale, or repair value using condition, mileage, configuration, location, and comparable outcomes. |
| **Maintenance planning** | Estimate failure or service risk from usage and maintenance history so inspections can be prioritized. |
| **Fleet optimization** | Support assignment, replacement, utilization, and procurement decisions using cost and operating profiles. |
| **Quality control** | Predict inspection results or manufacturing defects from process, component, and test measurements. |

## Recommended Data Attributes
- Make, model, configuration, age, mileage, and condition
- Maintenance events, repairs, inspections, and component replacements
- Trip, utilization, route, load, fuel, or charging summaries
- Purchase price, operating cost, residual value, and market comparables

## Evaluation Split & Benchmark Considerations
- The available automotive benchmarks demonstrate multiclass classification: the model must distinguish several outcomes rather than only yes versus no.
- Small benchmark tables are useful for checking a workflow, but real fleet data often needs grouped evaluation by vehicle and time to prevent history from the same asset appearing on both sides of a split.
- Cost-sensitive evaluation matters: confusing similar vehicle categories may be less serious than missing a safety-critical state.

## Privacy, Governance & Regulatory Compliance
- Vehicle and trip data can reveal locations, routines, and driver behavior. Separate data needed for maintenance or fleet operations from data that enables unnecessary surveillance.
- For safety-related decisions, use predictions to prioritize qualified inspection and preserve rule-based safeguards. A benchmark score isn't evidence that a model is safe for autonomous control or safety certification.
