Introduction to Artificial Intelligence and Machine Learning

AI Experience

• Artificial Intelligence (AI) involves creating intelligent systems that can perform tasks that typically require human intelligence.

Types of AI

• Machine Learning (ML): a subset of AI that involves training models on data to make predictions or decisions.
• Narrow AI (Weak AI): designed to perform a specific task, such as facial recognition or language translation.
• General AI (Strong AI): designed to perform any intellectual task that a human can.

Types of Machine Learning

• Supervised Learning: the model is trained on labeled data to make predictions on new data.
• Unsupervised Learning: the model is trained on unlabeled data to identify patterns or relationships.
• Reinforcement Learning: the model learns through trial and error by receiving rewards or punishments.
• Semi-supervised Learning: combines supervised and unsupervised learning approaches.

AI Lifecycle

• Defining the Problem: identify a problem or opportunity and define a goal for the AI model.
• Preparing Data: collect, clean, and preprocess data for the model.
• Training: train the model on the prepared data.
• Testing: evaluate the model's performance on a test dataset.
• Evaluating the Model: assess the model's accuracy, confidence, and bias.

Machine Learning: Data Preparation (Cleaning)

• Duplicates: identify and remove duplicate data points to prevent biases.
• Missing Data: handle missing data points, such as through imputation or interpolation.
• Invalid Data: detect and remove invalid or outlier data points.

Machine Learning: Testing

• Testing for Bias: evaluate the model's fairness and identify biases.
• Measuring Accuracy and Confidence: assess the model's performance using metrics such as accuracy, precision, and recall.

Decision Trees

• How Decision Trees are Made: a supervised learning approach that involves splitting data into subsets based on features.
• Solving Problems with ML Models: decision trees can be used for classification and regression tasks.

Bias in AI

• Bias in, Bias out: biased data can lead to biased models, which can perpetuate and amplify existing social inequalities.
