AI has the power to revolutionize industries, from automating workflows to generating valuable insights. That you’ve probably heard before. And as always there’s a catch: AI is only as good as the data it learns from. Poor-quality data leads to biased models, inaccurate predictions and costly mistakes. As many companies struggle with incomplete, inconsistent or messy data, does that mean your AI dreams should end here? In fact, no. In this blog, we’ll explore what ‘high-quality’ data is and our best practices for starting from imperfect datasets.
Why high-quality data is essential for valuable AI
AI models learn patterns and make decisions based on the data they’re trained on. If the input data is flawed, the output will be unreliable: garbage in, garbage out. Because AI systems require substantial time and effort to build, you’ll want certain assurances it’ll be worth the investment. That’s why high-quality data is essential for ensuring accurate predictions, valuable insights, and effective automation.
And why poor data quality allows for serious risks. Bias in training data can result in unfair or misleading outcomes. At the same time, inconsistencies and missing values can cause AI to misinterpret information, leading to unpredictable results. And outdated data may drive decisions based on obsolete trends. The biggest threat? AI might generate results that appear correct but are fundamentally inaccurate, making it difficult to distinguish between right and wrong. Without a strong data foundation, even the most advanced AI models can fail. So when do you have a strong data foundation?
What about using AI as a data cleaner?
AI isn’t just dependent on high-quality data, it can also help improve it. Intelligent algorithms can fill in missing values for more complete data. Anomaly detection helps identify outliers and inconsistencies that might otherwise go unnoticed. AI can also identify redundant or conflicting entries, streamlining datasets. Finally, normalization and standardization enforce consistency, making data more structured and reliable for AI applications.
However, AI-driven data cleaning isn’t foolproof. If there’s a flaw somewhere in the process, AI may reinforce incorrect patterns rather than fix them. To prevent this, organizations should implement safeguards: either maintain a small, verified dataset for validation or have human experts review AI-refined data. Even with these precautions, AI-driven data cleaning can significantly speed up the process.
Fixing data at the source
Although AI-driven data cleaning can be a powerful tool when you know you don’t have high-quality data, there are other, sometimes better, options.
- Generating synthetic data: Simulations can be a fast solution for data scarcity. By defining specific parameters, simulations can produce endless data, helping identify trends and patterns when real-world data is lacking or insufficient.
- Leveraging external data sources: Both paid and freely available, external data from sources like governments, research institutions, and other companies can enrich your dataset, providing additional context and improving the AI model’s accuracy.
- Using alternative data sources: Gathering data from different systems or creating new collection methods can improve data relevance and accuracy. For example, you might not have a sensor in place that captures when a machine breaks down, but maybe your conveyor belt stops working and sends an alert as a result, which can be captured.
- Improving existing databases and collection methods: A more long-term solution is focusing on improving their existing databases and data collection methods. Even when you’re still building the AI system, better-designed data systems can automate reporting and even simulate basic insights AI might provide in the future.
- Implementing federated learning models: In privacy-sensitive sectors, federated learning allows you to train AI models using decentralized data without compromising privacy, as the raw data is never shared across systems.
From imperfect to powerful
High-quality data is the cornerstone of effective AI, but no dataset is perfect. By leveraging a combination of continuous improvements and proactive data-gathering strategies, businesses can refine their data to unlock their full AI potential. So how do you know which strategy will work best for you? You have to define what you want to do before you define how to get there. Typically, this is why we set up dedicated ideation workshops in which we get to the bottom of why you want to invest in AI and what you want to get out of it. This helps define clear data strategies, assess data quality, set up improved data-gathering processes, or even algorithmically improve your existing dataset. That’s how, with the right approach, AI can transform not only your insights but also the way you manage and improve your data over time.
