    AI Hot Sauce Taste Test Challenge

    Key TopicsAI-optimized vs Commercially Available Hot Sauce: Angelo and Petter perform a blind taste test with three different hot sauces, one of which is AI-optimized, to see if they can determine which one is created by AI. Background of the AI Hot Sauce Creators: A brief insight into the story of Shekeib and Shohaib, the two brothers who combined their passion for data science and business to create an AI-optimized hot sauce. Understanding Bayesian Optimization: A comprehensive discussion on Bayesian Optimization, a technique that uses previous knowledge to influence future decisions, perfect for creating unique hot sauce recipes. Discussion on Other Optimization Techniques: Petter invites Angelo to delve into the different types of optimization algorithms and their pros and cons. Understanding Gradient Descent: Angelo gives a brief introduction to the concept of Gradient Descent, a popular optimization algorithm, explaining it as akin to finding a valley when on a mountain. RecommendationsCheck out the previous episode interviewing the creators of the AI-optimized hot sauce to understand their process better.For tech enthusiasts interested in AI and its applications, further exploration into optimization techniques like Bayesian Optimization and Gradient Descent can be insightful.Episode Quotes"Hot sauces are part of my favorite start of the day, so it'd be interesting to see what AI could come up with here." - Petter Graff "Bayesian is an optimization technique that centers around using your previous knowledge to influence the future and that works really well." - Angelo Kastroulis "Bayesian can kind of skip a bunch of steps because you've got a better second try." - Angelo Kastroulis "The algorithm of gradient descent basically goes like this. If you're trying to find from where you are to where you should go, imagine that you're on a mountain trying to find the valley." - Angelo Kastroulis Host: Angelo Kastroulis Executive Producer: Náture Kastroulis Producer: Albert Perrotta Communications Strategist: Albert Perrotta Video/Audio Engineer: Ryan Thompson Music: All Things Grow by Oliver Worth

    AI Hot Sauce Brothers - Part 1

    Introduction Shekeib and Shohaib join the podcast as guests to talk about their experience with creating hot sauces using AI optimization.They created a special hot sauce, named "Counting Sauce," specifically for the podcast hosts.The Making of Counting Sauce This is a unique hot sauce that includes pineapple and mango flavors.The sauce was created as a token of appreciation for being featured on the podcast.Journey through Different Versions of the Sauce The hosts have tried versions 19, 20, 21, and they just received version 25.There will be a blind taste test to determine if they can tell the difference between the different iterations and compare them with other sauces to tell which is AI-created.Optimization Process The process involves optimizing the amount of each ingredient.They use a Gaussian process regression model and an acquisition function called Expected Improvement for the optimization.Choice of Ingredients The base hot sauce has five main ingredients: vinegar, pepper, jalapeno, and lime.After 25 iterations, the differences in taste become so minute it becomes hard to tell the difference.Subjective Taste Testing Shekeib talks about how his taste tolerance changes after tasting hot sauces all day.They involved family and friends in the tasting process and asked for ratings on a scale of one to ten.The Learning Curve of the AI Early on, the AI would try extreme variations like too much or too little salt.It learned quickly from feedback and adjusted accordingly.Strength of Bayesian Optimization The AI can learn mathematically from feedback and apply the learnings, making the optimization process quicker and more efficient.It was also able to tweak multiple ingredients simultaneously, unlike a human who might focus on one ingredient at a time.No Prior Experience in Hot Sauce Making Both brothers had no prior experience or generational knowledge in hot sauce making.The AI managed to create a decent hot sauce in just five iterations.Power of Bayesian Optimization with Human Expertise The brothers emphasize the importance of having a human expert in the loop of Bayesian optimization.The AI simulates the intuition and experience of a human expert, but having a real human guide the process further enhances the results.Application Beyond Hot SauceThey discuss the potential of their Bayesian optimization process in other areas such as drug discovery.The process can be guided by human experts in the respective fields for even better results.
