Continual Learning and Catastrophic Forgetting How Agents Remember Without Forgetting

How AI agents can learn continuously across tasks and environments without overwriting what they already know — the science and practice of lifelong machine learning
23 Feb 2026

Multi-Agent Reinforcement Learning Teaching Agents to Cooperate Compete and Coexist

Explore multi-agent reinforcement learning: how multiple RL agents learn simultaneously, coordinate under uncertainty, and produce emergent strategies in cooperative, competitive, and mixed-motive settings
22 Feb 2026

Temporal Abstraction and the Options Framework How Agents Learn to Think in Subgoals

Understand how AI agents escape the curse of shortsightedness by learning reusable subgoals and temporally extended actions through the Options Framework

Automatic Prompt Optimization with DSPy Building Self-Tuning Agent Pipelines

Learn how DSPy reframes prompt engineering as a compilation problem, letting agents automatically discover better instructions, few-shot examples, and reasoning strategies through optimization

Causal Reasoning and Intervention Planning in AI Agents

How AI agents can move beyond correlation to understand cause and effect, enabling more robust planning, better tool use, and reliable interventions in the real world

Agent Evaluation and Benchmarking for Measuring What Matters

Learn how to systematically evaluate AI agent performance using benchmarks, metrics, and evaluation frameworks that go beyond simple accuracy
18 Feb 2026

Role Specialization and Crew Based Multi Agent Architectures

How assigning specialized roles to AI agents and orchestrating them as a crew produces better outcomes than monolithic single-agent systems
17 Feb 2026

Inverse Reinforcement Learning Inferring Goals From Behavior

Learn how inverse reinforcement learning lets AI agents discover hidden reward functions by observing expert behavior, and why it matters for agent alignment and autonomous systems
