What is Reward Hacking in Reinforcement Learning and How Do We Prevent It?
Reward hacking is when an AI agent finds a way to get a high reward without doing the task that we really wanted. The reward goes up, but the real goal is not achieved.
How do you become a Forward Deployed Engineer?
Forward Deployed Engineer is a role we reach by first becoming an engineer who can ship with an AI coding agent, then learning AI engineering, integrations, and deployment inside a customer's environment. We prove it with one project that adds an AI feature to a system we did not write.
How does K-Means Clustering work?
K-Means Clustering is a Machine Learning method that automatically splits data into K groups, where each item belongs to the group whose center is closest to it. It finds these groups on its own, without anyone telling it the correct answers.
How does a voice agent handle the user and agent talking at the same time?
A voice agent handles the user and agent talking at the same time by listening even while it speaks, removing its own voice from what it hears, deciding what kind of overlap it is, and then either continuing to speak or stopping to give the turn to the user.
What is a Reward Model and How Is It Trained?
A Reward Model is a model that reads a prompt and an answer, and gives back one number that tells how good that answer is as per human preference. It is trained on pairs of answers where humans picked the better one.
How does Self-Supervised Learning work?
Self-Supervised Learning is a way of teaching a machine where the data creates its own labels, so the machine learns from raw data with no human labeling.
What is Actor-Critic in Reinforcement Learning? The Advantage Function Explained
Actor-Critic is a way of training an AI agent where one part, the Actor, picks the actions, and another part, the Critic, judges how good each action was right after it happens. This judgment is called the advantage, and it tells the Actor how much better or worse an action was than usual.
How do an AI Engineer and a Software Engineer differ?
An AI Engineer and a Software Engineer both build software with a coding agent, but a Software Engineer builds systems that give the same output every time, while an AI Engineer builds products on top of AI models whose output can change every time.
How does a voice agent recover from a false interruption?
A voice agent recovers from a false interruption by pausing its speech instead of stopping it, waiting a short moment to check if the user really said something, and then continuing from where it paused if the user did not.
