Master Thesis- Leveraging AI for Scalable and Automated Data Quality Validation

In Toyota Material Handling Europe we are over 13500 colleagues passionate about supporting companies of all sizes with todays and tomorrows material handling challenges. Because we know that our business and our industry are essential and sometimes even critical for you for daily life and society at large.

In a rapidly growing high-tech industry in fast transformation Toyota Material Handling Europe is stable global and influential. We are committed to continuous improvement and innovation and we aim to strengthen our capabilities as a learning organisation.

Background

Data Quality is a paramount factor in many different areas and as such it is important to keep the quality as high as possible. Poor data quality can lead to flawed analytics misguided decisions and significant financial todays data driven world organizations rely on accurate complete and consistent data to power AI models automate processes and gain competitive insights. However manual data quality checks are time-consuming and prone to human error. This thesis explores automated data quality testing a scalable approach that leverages AI to ensure data integrity with minimal human intervention. By automating these checks businesses can improve efficiency reduce risk and unlock the full potential of their data assets.

At Toyota Material Handling Europe we work with big data at scale across multiple domains including Business Intelligence (BI). Ensuring data quality in such environments is critical because even minor inconsistencies can cascade into major operational and strategic errors.

Problem Statement

Despite the growing importance of data quality most organizations still depend on manual or rule-based processes that cannot keep pace with the volume and complexity of modern datasets. These traditional methods often fail when it comes to more complex issues such as contextual anomalies semantic inconsistencies or patterns indicating systematic data transformation errors leading to unreliable analytics and operational large-scale environments like Toyota Material Handling Europe where data powers BI dashboards and decision-making the challenge becomes even more pronounced. There is a growing need to explore how AI can support the identification of such subtle and hard-to-detect data quality problems. By leveraging AI to understand data patterns and flag anomalies we aim to move towards more intelligent and proactive data quality assurance.

Thesis Objectives

The thesis will focus on:

• Investigate how AI techniques can be applied to detect complex data quality issues that are not easily captured by traditional validation methods.
• Identify and implement key data quality dimensions (e.g. accuracy completeness consistency freshness anomaly detection) in an automated testing pipeline.
• Evaluate the performance and scalability of the proposed solution on production ready datasets.
• Provide insights and recommendations on how AI can be incorporated into a long-term strategy for proactive data quality assurance.

Your Contribution

As a thesis student you will:

• Will work with technology such as Snowflake Python AI & ML Azure DevOps and Pipelines.
• Have access to an AI playground environment where you can utilize LLMs and ML tools
• Explore how AI can be used to detect complex and subtle data quality issues beyond traditional rule-based checks.
• Investigate what metrics are important to ensure data quality
• Investigate how to automate and flag for erroneous data points and how to amend them
• Create end-to-end pipelines to run the tests and notify about relevant failures
• Benchmark proposed solution against traditional methods
• Provide guidelines and recommendations to adopt for future reference
• A report describing the proposed approach findings and recommendations
