Data Breakthroughs - Episode 8: The Office Kitchen Paradox
Real-world data problem solving in action! Irena Bojarovska and host Lior Barak tackle a community-submitted challenge for the first time during the recording.
Problem Category: Machine Learning & AI Implementation Runtime: 50 minutes
The Challenge: A hackathon team built a smart kitchen demand forecasting model with 91% accuracy, but the company is still throwing away 20-25% of fresh products weekly while running out of popular items.
The Solution: The breakthrough isn't about fixing the model, it's about fixing the data. The model is missing critical inputs (office attendance, special events) and is operating blindly due to data quality problems. The real solution combines better data, human-AI collaboration, and proper A/B testing.
Key Takeaways: • Model accuracy ≠ real-world performance (91% test accuracy doesn't guarantee waste reduction) • Data quality and contextual information are your foundation (garbage in, garbage out) • Humans should augment the model, not be replaced by it (hybrid approach wins)
