013 Data cleaning and preprocessing
Manage episode 504002358 series 3678442
A patient's record is a chaotic mix of notes, lab test results, and codes. We can navigate the mess, but how can an AI? The answer lies in data cleaning and preprocessing – the most critical, yet unglamorous, step in building medical AI.
This episode of The Health AI Brief explains why this process is like meticulously preparing ingredients for a complex recipe. We break down the key steps - from handling missing values to standardising formats, and offers three essential takeaways for appraising new AI studies and understanding why a tool that works in one hospital might fail in yours.
