Study Notes
No-Code AI
- Users input data to train AI models which can be built quickly, saving time and effort.
- Accessible to those without coding skills, such as business analysts or marketers.
- Quick model building is achieved through drag-and-drop functionality and simple data inputs.
- Teams from different departments can collaborate because no technical expertise is needed.
- Reduces the need for technical resources, cutting down costs related to hiring developers or data scientists.
Types of AI Problems
- Prescriptive Problems - tasks where steps can be repeated to get the same result, like adding sales figures in a spreadsheet (can be done in Excel).
- Predictive Problems - Problems where there is no set of repeatable steps and predictions need to be made based on patterns in data. For example, predicting sales for next year based on market trends, seasonality and customer behavior.
Examples of Predictive Problems Solved By AI
- Forecasting future sales based on historical data.
- Identifying customers who are most likely to buy a product.
- Predicting when equipment is likely to fail.
Teachable Machine Example
- Teachable Machine is a platform that allows users to build an image classification AI model without code.
- Users upload images of apples, oranges and bananas into separate classes.
- Clicking the "Train Model" button allows Teachable Machine to learn from the uploaded images.
- The model can then be tested by uploading images from a "Test Data" folder and observing if the AI correctly classifies them.
Learning Agents
- Performance Element - Executes actions in the environment.
- Critic- Measures the agent's performance and provides feedback.
- Problem Generator - Suggests actions that lead to new or informative experiences.
Types of Learning Agents
- Reactive Agents - Use machine learning to make decisions based on past experiences without an internal model of the world.
- Deliberative Agents - Have an internal model and use past experiences to plane and reason about future actions.
Music Streaming Service Example
- A music streaming service that learns from your listening habits is a learning agent.
- Learning Element - Notices which songs and genres you skip or listen to fully.
- Performance Element - Plays music based on your preferences.
- Critic - Uses your interactions (like skips or replays) to evaluate how well the recommendations match your taste.
- Problem Generator - Might suggest a new genre or artist to see if you like them, enhancing your listening experience and its own data on your preferences.
Other Learning Agents
- A robot that learns to navigate a maze by adjusting its movements based on the feedback it receives from hitting walls or reaching the end of the maze.
- A self-driving car that learns to drive safely by adjusting its steering, acceleration and braking based on the feedback it receives from cameras and sensors.
- A machine learning algorithm that learns to classify images by adjusting the parameters of its neural network based on the feedback it receives from labelled training data.
What is No-Code AI?
- Allows business users to build AI models without writing any code.
- No coding is required; no Python, no R, no technical programming at all.
How No-Code AI Works
- No-code AI platforms provide an easy-to-use web or mobile interface, similar to a spreadsheet.
PEAS
- Performance - A measure of how well the agent is performing.
- Environment - The world in which the agent operates.
- Actuators - How the agent takes action in the environment.
- Sensors - How the agent perceives the environment.
PEAS Examples
-
Automated Taxi Problem
- Performance measure: Safe, fast, legal, max revenue, min cost, min fuel, etc.
- Environment: City roads, traffic, pedestrians, bikers, construction. etc.
- Actuators: Car controls (steering, gas pedal) and human interface.
- Sensors: Cameras, radar, laser range finder, GPS, mapping, engine sensors, human input devices.
-
Medical Diagnosis System
- Performance measure: Healthy patient, minimize costs, lawsuits.
- Environment: Patient, hospital, staff.
- Actuators: Screen display (questions, tests, diagnoses, treatments, referrals).
- Sensors: Keyboard (entry of symptoms, findings, patient's answers).
-
Part-Picking Robot
- Performance measure: Percentage of parts in correct bins.
- Environment: Conveyor belt with parts, bins.
- Actuators: Jointed arm and hand.
- Sensors: Camera, joint angle sensors.
-
Interactive English Tutor
- Performance measure: Maximize student's score on test.
- Environment: Set of students.
- Actuators: Screen display (exercises, suggestions, corrections).
- Sensors: Keyboard.
What is an Intelligent Agent?
- An autonomous entity which acts to achieve goals in an environment.
- Uses observation through sensors and consequent actuators.
- May learn or use knowledge to achieve its goals.
- Can be very simple or very complex.
- Example: A reflex machine, such as a thermostat.
Human Agent vs Robotic Agent
-
Human Agent
- Sensors: Eyes, ears, and other organs.
- Actuators: Hands, legs, mouth, and other body parts.
-
Robotic Agent
- Sensors: Cameras and infrared range finders.
- Actuators: Various motors.
Agents and Environments
- Thermostat
- Cell Phone
- Vacuum Cleaner
- Robot
- Alexa Echo
- Self-Driving Car
- Human
- etc.
What is a Percept?
- An agent's perceptual inputs at any given moment.
- Percept Sequence: Complete history of everything the agent has ever perceived.
- An agent's choice of action can depend on the entire percept sequence observed to date, but not on anything it hasn't perceived.
- The agent is fully specified by the choice of action for every possible percept sequence.
The Structure of Intelligent Agents
- Architecture - The hardware or machinery that the intelligent agent operates on, including sensors and actuators (i.e. a personal computer running a software agent, a self-driving car with sensors, or even a camera that responds to environmental inputs).
- Agent Function - The abstract function that maps percepts (what the agent perceives) to actions.
- Percept Sequence - The history of all the information the agent has sensed, which helps it decide what actions to take.
- Agent Program - The concrete implementation of the agent function. The agent program takes percepts from sensors and computes the appropriate action.
Agent Structure
-
Agent = Architecture + Agent Program
- Architecture = the machinery that an agent executes on
- Agent Program = an implementation of an agent function
Behavior of Agent
- The set of actions that an agent performs based on a sequence of percepts.
- For instance, if a robot senses an obstacle (percept), it turns right (action).
- Percept: The input an agent receives from its environment at any given moment. This could be visual, auditory, or sensor-based data.
- Percept Sequence: The complete history of everything an agent has perceived up to a certain point.
Rational Agents
- Make decisions that maximize their chances of achieving goals, based on their knowledge and perceptions of the environment.
- It acts to achieve the best possible outcome, or when faced with uncertainty, the best expected outcome.
- Example: A navigation app (the agent) analyzes the available routes from point A to B and chooses the quickest route based on real-time traffic data.
