Keywords

💡Generative AI

Generative AI, also known as Generative Adversarial Networks (GANs), is a subset of AI that focuses on creating new content such as text, images, audio, and synthetic data. It is a technology that learns from existing data and uses that knowledge to generate new, similar content. In the video, Dr. Gwendolyn Stripling explains that Generative AI is a type of artificial intelligence that can produce various types of content, emphasizing its ability to create new data instances based on learned probability distributions.

💡Artificial Intelligence (AI)

Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think and act like humans. In the context of the video, AI is described as a branch of computer science that deals with creating intelligence agents capable of reasoning, learning, and acting autonomously. It is the overarching discipline that encompasses machine learning, deep learning, and generative AI.

💡Machine Learning

Machine Learning is a subfield of AI that involves the development of algorithms and statistical models that enable computers to learn from and make predictions or decisions based on data. The video script explains that machine learning models can be trained from input data, and these trained models can then make useful predictions on new, unseen data.

💡Supervised Learning

Supervised Learning is a type of machine learning where the model is trained on labeled data, which includes a tag or label for each piece of data. In the video, an example is given of a restaurant owner using historical data with labels such as bill amount and tipping behavior to predict future tips, illustrating how the model learns from past examples to make future predictions.

💡Unsupervised Learning

Unsupervised Learning is another type of machine learning where the model works with unlabeled data, meaning the data does not have any predefined tags or labels. The video script describes an example of unsupervised learning where the goal is to group or cluster employees based on tenure and income to discover patterns or trends without any prior labeling.

💡Deep Learning

Deep Learning is a subset of machine learning that uses artificial neural networks with many layers to process complex patterns in data. The video explains that deep learning models are inspired by the human brain and can learn to perform tasks by processing data and making predictions. These models are particularly adept at handling large volumes of data and identifying intricate patterns.

💡Neural Networks

Neural Networks are a set of algorithms modeled loosely after the human brain that are designed to recognize patterns. They consist of nodes or neurons interconnected in layers, which allow the network to learn from data. In the video, neural networks are described as the foundation of deep learning, capable of learning complex patterns and making predictions.

💡Generative Model

A Generative Model is a type of statistical model that generates new data instances based on a learned probability distribution of existing data. In the video, it is explained that generative models, unlike discriminative models, are used to generate new content rather than classify or predict labels for existing data points.

💡Discriminative Model

A Discriminative Model is used to classify or predict labels for data points and is trained on a dataset of labeled data points. The video script contrasts discriminative models with generative models, explaining that while discriminative models learn the relationship between data features and labels, generative models learn the underlying distribution to create new data instances.

💡Transformers

Transformers are a type of deep learning architecture that is particularly effective in handling sequential data, such as natural language. The video script highlights the importance of transformers in the context of generative AI, explaining that they consist of an encoder and decoder that process input sequences to generate outputs for tasks like language translation or text generation.

💡Prompt

A Prompt in the context of generative AI is a short piece of text given to a model to guide its output. The video script discusses prompt design as a critical aspect of working with large language models, where the prompt is crafted to elicit the desired response from the model, such as generating a specific type of content or completing a sentence.

💡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 various downstream tasks. The video script mentions foundation models as having the potential to revolutionize industries by providing a base for tasks such as sentiment analysis or object recognition, which can then be customized for specific applications.
