Probabilistic Graphical Models

Probabilistic Graphical Models (PGMs) are frameworks that use graphs to represent probabilistic relationships between variables. They visually depict dependencies and independencies, enabling efficient computation and inference in complex systems involving uncertainty.

Hidden Markov Models

Hidden Markov Models (HMMs) are statistical models that describe systems with unobservable "hidden" states and observable events. They infer the most likely sequence of hidden states from a sequence of observations.

Gaussian Mixture Models

Gaussian Mixture Models are probabilistic models assuming data points arise from a combination of multiple Gaussian distributions. They estimate the parameters of these underlying distributions to cluster data, often employing the Expectation-Maximization algorithm for fitting.

LIME (Local Interpretable Model-agnostic Explanations)

LIME (Local Interpretable Model-agnostic Explanations) explains individual predictions of any complex AI model. It approximates local behavior with a simpler, interpretable model to show why a specific decision was made.

Hidden Markov Models for POS

Hidden Markov Models (HMMs) for Part-of-Speech (POS) tagging are probabilistic sequence models that predict the most likely sequence of hidden POS tags given a sequence of observed words, inferring linguistic categories.

Language Modeling

Language modeling is the task of assigning a probability to a sequence of words, or predicting the next word in a sequence given the preceding words. It's fundamental for understanding and generating human language.

IBM Models

IBM Models are a series of five statistical models (Model 1-5) developed in the 1990s for machine translation. They established foundational concepts for word alignment and translation probability, crucial for early statistical machine translation systems.

Character-Level Models

Character-Level Models process text by analyzing individual characters to build representations of words and sentences. This approach helps handle misspellings, rare words, and morphological variations, making them robust in various NLP tasks.

ELMo (Embeddings from Language Models)

ELMo (Embeddings from Language Models) is a neural network model from AI2 that generates contextualized word embeddings. It represents words differently based on their sentence context, enhancing performance across various natural language processing tasks.

GPT (Generative Pre-trained Transformer)

GPT (Generative Pre-trained Transformer) is a powerful large language model developed by OpenAI. It utilizes a transformer architecture, pre-trained on massive text datasets, to generate human-like text and perform various Natural Language Processing tasks.

GPT-2

GPT-2 is an early transformer-based large language model developed by OpenAI in 2019. It demonstrated unprecedented ability to generate human-like text across various topics, marking a significant leap in NLP.

GPT-3

GPT-3 (Generative Pre-trained Transformer 3) is an advanced large language model developed by OpenAI. It uses deep learning to generate human-like text, translate languages, and answer questions across various domains.
