2. GENERATIVE AI: AN OVERVIEW
2.1 Definition and Key Concepts
Generative AI refers to models and algorithms designedtocreatenew,realisticdatapointsoroutputsbased on patterns learned from existing data. Unlike traditional machine learning, which often focuses on prediction or classification,generativeAIcreatesnewinstances,makingit especially valuable in scenarios where data availability or qualityisaconcern.
2.2 Core Technologies
Generative Adversarial Networks (GANs): GANs consist of two neural networks the generator and discriminator that compete against each other. The generator creates data, while the discriminator evaluates its authenticity. Over time, the generator produces increasingly realistic outputs. Applications: Synthetic data generation, anomaly detection
Variational Autoencoders (VAEs): VAEs focus on learning latent representations of data and reconstructing it to generate new samples. Applications: Filling in missing data, augmenting datasetsformachinelearning
Transformer-Based Models (e.g., GPT-4): Transformers process sequential data, excelling in generating text, code, and structured data representations. Applications: Automating pipeline creation, query optimization
