Listen carefully to the following passage:
In today's lecture, we will explore the advances in artificial intelligence, focusing on machine learning and its applications. Machine learning is a subset of AI that enables computers to learn from data and improve their performance over time. One of the most significant developments is supervised learning, where a model is trained on labeled data. This method is widely utilized in applications like image recognition and natural language processing. Conversely, unsupervised learning analyzes unlabelled data, discovering hidden patterns without explicit instructions. This technique is critical in market segmentation and anomaly detection.
We also have reinforcement learning, which is inspired by behavioral psychology. Here, agents learn by interacting with their environment and receiving feedback in the form of rewards. For instance, this approach has been pivotal in developing AI for gaming and robotics. Finally, it's essential to address ethical considerations surrounding AI, including bias in data and the implications of autonomous systems on employment.
