On this episode of Learning from Machine Learning, I had the privilege of speaking with Lukas Biewald, co-founder and CEO of Weights & Biases. We traced his journey from programming games as a kid to building one of the most essential tools in AI development today. Lukas's career demonstrates that conviction often matters more than consensus—from surviving the AI winter in the mid-2000s when he was coached to remove "AI" from investor pitches, to the AlphaGo moment that changed everything and led him to take an unpaid internship at OpenAI in his thirties.

Lukas's philosophy on "automating the automation" reveals why AI developers have become the most powerful people within organizations—they're a smaller market but wield disproportionate influence. He shares his view that "if you zoom out, AI is so underhyped, you can't hype it enough." The recursive potential of machines improving machines is barely understood, yet it represents "the most powerful technology you could possibly build."

Most importantly, Lukas's philosophy that "feedback loops are your units of work" transforms how we approach both machine learning and life. He explains the necessity to stay technical as a leader: "If you're going to work for me, you better be able to do the IC job. And I do not know how companies function without that mindset." His advice to his younger self cuts through common doubts in emerging technologies: "you think you're late, but you're early." In a world racing towards progress at all costs, this reminder couldn't be more relevant.

A machine learning podcast that explores more than just algorithms and data: Life lessons from the experts. Welcome to "Learning from Machine Learning," a podcast about the insights gained from a career in the field of Machine Learning and Data Science. In each episode, industry experts, entrepreneurs and practitioners will share their experiences and advice on what it takes to succeed in this rapidly-evolving field.

On this episode of Learning from Machine Learning, I had the privilege of speaking with Maxime Labonne, Head of Post-Training at Liquid AI. We traced his journey from cybersecurity to the cutting edge of model architecture. Maxime shared how the future of AI isn't just about making models bigger—it's about making them smarter and more efficient.

Maxime's work demonstrates that challenging established paradigms requires taking steps backward to leap forward. His framework for data quality—accuracy, diversity, and complexity—offers a blueprint for anyone working with machine learning systems.

Most importantly, Maxime's perspective on learning itself—treating knowledge acquisition like training data exposure—reminds us that growth comes from diverse, high-quality experiences across different contexts. Whether you're training a model or developing yourself, the principles remain remarkably similar.

On this episode of Learning from Machine Learning, I had the privilege of speaking with Aman Khan, Head of Product at Arize AI. Aman shared how evaluating AI systems isn't just a step in the process—it's a machine learning challenge in of itself. Drawing powerful analogies between mechanical engineering and AI, he explained, "Instead of tolerances in manufacturing, you're designing for non-determinism," reminding us that complexity often breeds opportunity.

Aman's journey from self-driving cars to ML evaluation tools highlights the critical importance of robust systems that can handle failure. He encourages teams to clearly define outcomes, break down complex systems, and build evaluations into every step of the development pipeline.

Most importantly, Aman's insights remind us that machine learning—much like life—is less deterministic and more probabilistic, encouraging us to question how we deal with the uncertainty in our own lives.
