Accuracy Barrier (ACCBAR): Why we need new AI performance indicators for binary classification
Join us as we explore the fascinating world of AI and uncover a hidden danger lurking beneath the surface of seemingly impressive and common performance metrics, specifically Accuracy (ACC).
In this episode, we'll explore the concept of the Accuracy Barrier (ACCBAR) performance indicator and why relying solely on accuracy scores can lead to a false sense of security.
We'll examine:
The Accuracy Paradox: Discover how a 99% accuracy rate can be utterly misleading and why conventional performance indicators fall short in certain scenarios.
Accuracy Barrier (ACCBAR): Uncover this groundbreaking novel performance indicator that unveils the limitations of Accuracy -the most traditional metric- and exposes potential biases in AI models.
Real-World Implications: Learn how ACCBAR can revolutionize performance evaluation in various domains, from cybersecurity to medical diagnosis, by providing a more reliable assessment of AI systems.
Publication Bias and Confirmation Bias in Research: We'll discuss how ACCBAR can help researchers identify and address potential confirmation bias in their classifications, ensuring more robust and trustworthy AI development.
Don't miss this opportunity to gain a deeper understanding of AI performance evaluation and learn how to critically assess the true capabilities of AI systems.

Garbage In, Garbage Out (GIGO): Unlocking data insights with AI - Feature space distribution fitting
Welcome to the very first episode of our podcast, where we dive deep into the fascinating world of data, artificial intelligence, and cybersecurity. I'm Gürol Canbek. In this episode, we’ll explore one of the most critical concepts in AI: Garbage In, Garbage Out, or GIGO.
We often focus on building smarter algorithms, but what happens when the data we feed into these systems is flawed or incomplete? Like using spoiled ingredients in a recipe, bad data can lead to disastrous results. In this episode, I'll discuss my latest research on how data quality affects AI's ability to generate insights and how we can avoid those "bad ingredients."
We’ll talk about patterns, data fingerprints, and even some surprising parallels between natural phenomena like earthquakes and your smartphone apps! 🧐
For full access to the research behind this episode, you can read the paper here: bit.ly/GIGOpaper (https://bit.ly/GIGOpaper).
Also, be sure to check out more of my work at gurol.canbek.com (https://gurol.canbek.com).
Join me as we uncover how clean, well-structured data can make all the difference in AI, and why GIGO is more relevant than ever in our increasingly data-driven world.
