www.tstc.edu Hospitals and medical centers stay active around the clock, and medical personnel rely on advanced biomedical equipment to make the difference when life is literally hanging in the balance. They demand that the equipment they use be repaired quickly and maintained in first-class condition to avoid malfunctions that might slow down or stop medical procedures. The up-keep and repair of this equipment requires highly skilled biomedical equipment technicians, professionals dedicated…

Pulley'ing Your Own Weight

Video

Using common materials (spools, string, soap), students learn how a pulley can be used to easily change the direction of a force, making the moving of large objects easier. They see the difference between fixed and movable pulleys, and the mechanical advantage gained with multiple/combined pulleys. They also learn the many ways engineers use pulleys for everyday purposes. View the full activity at TeachEngineering:…

Q-Learning Explained - A Reinforcement Learning Technique

Video

💡Enroll to gain access to the full course: https://deeplizard.com/course/rlcpailzrd Welcome back to this series on reinforcement learning! In this video, we'll be introducing the idea of Q-learning with value iteration, which is a reinforcement learning technique used for learning the optimal policy in a Markov Decision Process. We'll illustrate how this technique works by introducing a game where a reinforcement learning agent tries to maximize points, and through this, we'll also learn…

Always in high demand, RCTs are a pivotal part of any facility…

Reinforcement Learning: Crash Course AI #9

Video

Reinforcement learning is particularly useful in situations where we want to train AIs to have certain skills we don’t fully understand ourselves. Unlike some of the techniques we’ve discussed so far, reinforcement learning generally only looks at how an AI performs a task AFTER it has completed it. And when an AI completes that task figuring out when and how to reward an AI, called credit assignment, is one of the hardest parts of reinforcement learning. So today, we’re going to explore these…
