Representational learning is a class of machine learning that focuses on automatically discovering the most appropriate way to represent data. By learning these representations directly from the data, it eliminates the need for manual feature engineering and allows models to effectively process and understand complex inputs.

Representational Learning

Supervised learning is a type of machine learning problem where the objective is to predict a designated unknown label based on known inputs. This approach requires a training dataset consisting of examples for which the ground truth labels are already known, allowing the model to learn the mapping from inputs to classifications.

Supervised Learning

Machine learning is a field that studies how computer systems can utilize experience—typically in the form of data—to improve their performance on specific tasks. It integrates principles from statistics, data mining, and optimization, and is frequently employed as a primary method for implementing artificial intelligence solutions.

Technological intelligence designed by humans, displayed through machines instead of humans.  
Intelligent agents - In relation to artificial intelligence, it is the machine or the program that intakes information from its environment and processes that information to achieve certain goals.

Dive into Deep Learning

There is no exact definition for Natural Language Processing (NLP), but we could catch a glimpse through its goal and academic classification.
- The goal of this field (NLP) is to get computers to perform useful tasks involving human language. (Speech and Language Processing, 2nd edition)
- NLP is an interdisciplinary field of linguistics, computer science, information engineering, electrical engineering, psychology, and artificial intelligence. (Speech and Language Processing, 2nd edition; Wikipedia)

Natural language processing gives a computer the ability to analyze and synthesize human languages.

A smart home thermostat learns the daily routines of a household. It senses when people are home or away, monitors the current indoor and outdoor temperatures, and automatically adjusts the heating and cooling to maintain a comfortable temperature while minimizing energy consumption. Based on the core principles of an intelligent agent, which part of this process best represents the agent's primary 'goal'?

Consider the following scenario: An online retail website uses a system to suggest products to customers. This system tracks which products a user views, which items they add to their cart, and their past purchase history. Based on this data, and data from thousands of other users, the system displays a 'Recommended for You' section on the user's homepage, aiming to increase the likelihood of a sale. 

Analyze this system as an intelligent agent. In your answer, identify its environment, the information it processes, and its primary goal.

Analyzing an Intelligent Agent

Consider a factory's automated sprinkler system. It is equipped with heat sensors. If a sensor detects a temperature above 150°F, it automatically triggers the sprinklers in that specific zone until the temperature drops below 100°F. The system does not learn from past events or adjust its temperature thresholds. Based on the definition of an intelligent agent—a system that perceives its environment and takes actions to achieve specific goals—evaluate whether this sprinkler system qualifies as an intelligent agent. Justify your reasoning.
