Q & A

What is generative AI?

Generative AI is a type of artificial intelligence technology that can produce various types of content including text, imagery, audio, and synthetic data.

How is AI defined in the context of this script?

AI is described as a branch of computer science that deals with the creation of intelligent agents and systems that can reason, learn, and act autonomously.

What is the relationship between AI and machine learning?

Machine learning is a subfield of AI. It involves programs or systems that train a model from input data, enabling the model to make useful predictions from new, never-before-seen data.

What distinguishes supervised machine learning models from unsupervised ones?

Supervised models use labeled data that comes with a tag, while unsupervised models work with unlabeled data that has no tag, focusing on discovery and grouping within the data.

How does deep learning fit into the AI discipline?

Deep learning is a subset of machine learning methods that uses artificial neural networks to process more complex patterns than traditional machine learning models.

What is the main difference between generative and discriminative models?

Generative models generate new data instances based on a learned probability distribution, while discriminative models classify or predict labels for data points based on learned relationships from labeled data.

What is a prompt in the context of generative AI?

A prompt is a short piece of text given to a large language model as input, which can be used to control the output of the model.

What are the potential issues with Transformer models like hallucinations?

Hallucinations refer to the generation of nonsensical or grammatically incorrect words or phrases by the model, often caused by insufficient data, noisy data, lack of context, or insufficient constraints.

How can generative AI models be used for code generation?

Generative AI models can help in debugging source code, explaining code line by line, crafting SQL queries, translating code from one language to another, and generating documentation and tutorials for source code.

What is the role of Vertex AI Studio in working with generative AI models?

Vertex AI Studio allows developers to quickly explore and customize generative AI models for use in their applications on Google Cloud, providing tools and resources to facilitate the creation and deployment of these models.

What are Foundation models and how can they be utilized?

Foundation models are large AI models pre-trained on vast amounts of data and designed to be adapted or fine-tuned for a wide range of downstream tasks, revolutionizing industries and enabling capabilities like sentiment analysis, image captioning, and fraud detection.
