At its core, reward hacking, also known as reward misspecification or reward exploitation, happens when an AI agent , designed to maximize a specific reward signal, finds a way to achieve that reward in a way that was not intended  by the human designers. Instead of learning the desired behavior, the AI exploits loopholes or shortcuts in the reward function, often leading to unintended and potentially harmful outcomes. Think of it like this: you tell a child you'll give t

First-time funds , often referred to as emerging managers , represent a compelling, yet challenging, asset class for LPs . These are investment vehicles managed by teams that haven’t previously managed a full-fledged fund . While they lack the established track record of seasoned managers, they often bring fresh perspectives, innovative strategies, and a hunger to succeed that can translate into outsized returns . However, LPs must approach these investments with a nuanced un

Imagine training a powerful AI model using data spread across millions of smartphones, each containing highly personal information. Historically, the only way to do this was to gather all that data into a central server, a process fraught with privacy risks and logistical nightmares. Federated Learning offers a powerful alternative. At its core, Federated Learning is a distributed machine learning approach that enables model training on decentralized data residing on edge d

At its core, the Credit Assignment Problem (CAP) asks: "When an outcome occurs after a series of actions or decisions, how do we determine which specific actions were responsible for that outcome, and to what extent?"  In simpler terms, who gets the credit (or blame) for the success (or failure)? Imagine a scenario where you are playing a complex video game. You make a series of moves, and ultimately you either win or lose. How does the game AI, or even your own brain, figure

A Private Placement Memorandum, or PPM, is a legal document used in the private offering of securities. Unlike a public offering (where...

Reinforcement Learning (RL) has made tremendous strides in training agents to excel in complex environments. However, the real world is often populated with multiple interacting entities, not just a single agent acting in isolation. This is where Multi-Agent Reinforcement Learning (MARL) comes into play. MARL extends the principles of RL to scenarios where multiple agents learn and interact within a shared environment, aiming to achieve individual or collective goals. Wh

While venture capitalists (VCs) often occupy the limelight with their investments in groundbreaking startups, it’s the Limited Partners (LPs) who are the engine behind the entire ecosystem. LPs are the institutions and individuals who provide the capital that VCs invest. Their decisions, expectations, and strategic priorities have a profound impact on the types of companies that get funded, the direction of innovation, and the overall health of the venture capital landscape

Information diffusion, the process by which information spreads through a network, is a fundamental concept in various disciplines, from...
