💡Supervised Learning

Supervised learning is a type of machine learning where the model is trained on labeled data, which means the input data is associated with an output label. The goal is to train the model to predict the output for new, unseen data based on the patterns learned from the labeled training data. In the video, the example of predicting restaurant tips based on the total bill and order type (picked up or delivered) illustrates how supervised learning can be applied in real-world scenarios.

💡Unsupervised Learning

Unsupervised learning, in contrast to supervised learning, involves analyzing unlabeled data to find patterns or groupings naturally occurring within the data. The video provides the example of employee tenure and income, where the model might identify groups with high income-to-years worked ratios without prior labels. Unsupervised learning is about discovering hidden structures in the data.

💡Deep Learning

Deep learning is a specialized type of machine learning that uses artificial neural networks with multiple layers to analyze complex patterns in data. Inspired by the human brain, deep learning models can handle vast amounts of data and are particularly effective for tasks like image and speech recognition. The video explains deep learning as a subset of machine learning and introduces the concept of semi-supervised learning, where a model is trained on a small amount of labeled data and a larger amount of unlabeled data.

💡Discriminative Models

Discriminative models are a type of deep learning model that learns the relationship between the labels of data points and can classify new data points based on those learned relationships. These models are used for tasks like fraud detection or image classification. The video uses the example of labeling pictures as cats or dogs to illustrate how discriminative models function and their ability to classify data points.

💡Generative Models

Generative models, unlike discriminative models, learn the patterns in the training data and then generate new data that follows those patterns. These models are capable of creating new content, such as images, text, or audio, based on the input they have been trained on. The video provides the example of generating a new image of an animal based on patterns learned from unlabeled data points with features like two ears, four legs, and a tail.

💡Large Language Models (LLMs)

Large language models are a specific type of deep learning model designed to process and generate human-like text based on the input they receive. These models are pre-trained on vast amounts of data to understand language broadly and can then be fine-tuned for specific tasks or industries. The video explains that LLMs, such as ChatGPT and Google Bard, are used for various applications like text classification, question answering, and summarization, and can be fine-tuned with industry-specific data to solve particular problems.

💡Fine-tuning

Fine-tuning is the process of adjusting a pre-trained model to perform better on a specific task or data set. In the context of the video, this concept is applied to large language models, which are first pre-trained on a wide range of language problems and then fine-tuned with smaller, domain-specific data sets to address particular challenges in fields like retail, finance, or healthcare. The video uses the analogy of a generalist dog being trained for a specialized role to explain how LLMs are fine-tuned for specific applications.

💡Semisupervised Learning

Semisupervised learning is a machine learning paradigm that combines a small amount of labeled data with a large amount of unlabeled data for model training. This approach is particularly useful when labeling data is expensive or time-consuming. The video script describes an example where a deep learning model for fraud detection is trained on a small percentage of labeled transactions and then applied to a much larger set of unlabeled transactions to make predictions.

💡Text-to-Text Models

Text-to-text models are a type of generative AI model that processes input text and generates output text based on the patterns it has learned. These models are widely used for applications like language translation, text summarization, and dialogue systems.
