Keywords

💡Generative AI

Generative AI refers to a subset of artificial intelligence technology that has the capability to produce various types of content, such as text, imagery, audio, and synthetic data. It is a discipline within AI that focuses on creating models that can generate new data instances based on learned probability distributions from existing data. In the video, Generative AI is the central theme, with detailed discussions on its applications, models, and how it learns from data to create new content, exemplified by models like PaLM and LAMBDA.

💡Artificial Intelligence (AI)

Artificial Intelligence, or AI, is a branch of computer science that aims to create systems capable of performing tasks that would typically require human intelligence. These tasks include reasoning, learning, problem-solving, perception, and language understanding. In the context of the video, AI serves as the foundation for generative AI, with the goal of building machines that can think and act like humans, using methods and theories to achieve autonomous action.

💡Machine Learning

Machine learning is a subfield of AI that focuses on the development of algorithms and statistical models that allow computers to learn from and make predictions or decisions based on data. It enables systems to improve their performance over time without being explicitly programmed for every decision. In the video, machine learning is contrasted with generative AI, highlighting its role in training models from input data to make predictions on new, unseen data.

💡Supervised Learning

Supervised learning is a class of machine learning where the model is trained on a labeled dataset, which includes input-output pairs. The model learns to predict the output based on the historical data it has been trained on. In the video, an example of supervised learning is given where a model uses the total bill amount to predict future tip amounts based on whether an order was picked up or delivered.

💡Unsupervised Learning

Unsupervised learning is another class of machine learning where the model works with unlabeled data, aiming to identify patterns or groupings within the data itself. It is about discovery and finding structure in the data without any prior guidance on what the structure should look like. The video illustrates this with an example of clustering employees based on tenure and income to identify those on a fast track.

💡Deep Learning

Deep learning is a subset of machine learning that uses artificial neural networks with many layers to enable the processing of complex patterns in data. These neural networks are inspired by the human brain and can learn to perform tasks by processing data and making predictions. In the video, deep learning is positioned as a subset of machine learning methods and is integral to the functioning of generative AI, where it processes both labeled and unlabeled data using various learning methods.

💡Neural Networks

Neural networks are a series of algorithms that are modeled loosely after the human brain. They are composed of layers of interconnected nodes or neurons that can learn to perform tasks by processing data. These networks are a fundamental component of deep learning and are used in generative AI to learn complex patterns and generate new content. The video explains that neural networks can use both labeled and unlabeled data, which is referred to as semi-supervised learning.

💡Generative Model

A generative model is a type of machine learning model that generates new data instances based on a learned probability distribution of existing data. It essentially creates new content that is similar to the data it was trained on. In contrast to discriminative models that classify or predict labels for data points, generative models are about producing new content, as illustrated in the video with the example of generating a picture of a dog based on learned patterns.

💡Transformers

Transformers are a type of deep learning model architecture that is particularly effective for natural language processing tasks. They consist of an encoder to process the input sequence and a decoder to generate the output sequence. Transformers have been revolutionary in the field of NLP since 2018, enabling models to better understand the context and relationships in the data. The video mentions that the power of generative AI comes from the use of transformers, which can sometimes produce 'hallucinations' if not trained properly.

💡Prompt

A prompt is a short piece of text or input given to a generative AI model to guide the output. It is a tool used to control and shape the response generated by large language models. In the video, prompts are described as essential for designing outputs from generative AI models, with the example of asking a generative model about the meaning of life and receiving a contextual answer based on the prompt provided.

💡Foundation Model

A foundation model is a large AI model that is pre-trained on a vast amount of data and can be adapted or fine-tuned for a wide range of downstream tasks. These models are designed to be versatile and have the potential to impact various industries by performing tasks such as sentiment analysis, image captioning, and object recognition. The video positions foundation models as a key component of generative AI, capable of generating new content and providing personalized services.
