A visual representation of discriminative AI – Source: Analytics Vidhya Discriminative modeling, often linked with supervisedlearning, works on categorizing existing data. Generative AI often operates in unsupervised or semi-supervisedlearning settings, generating new data points based on patterns learned from existing data.
In the first part of the series, we talked about how Transformer ended the sequence-to-sequence modeling era of NaturalLanguageProcessing and understanding. Semi-Supervised Sequence Learning As we all know, supervisedlearning has a drawback, as it requires a huge labeled dataset to train.
Well do so in three levels: first, by manually adding a classification head in PyTorch* and training the model so you can see the full process; second, by using the Hugging Face* Transformers library to streamline the process; and third, by leveraging PyTorch Lightning* and accelerators to optimize training performance.
A lot of people are building truly new things with Large Language Models (LLMs), like wild interactive fiction experiences that weren’t possible before. But if you’re working on the same sort of NaturalLanguageProcessing (NLP) problems that businesses have been trying to solve for a long time, what’s the best way to use them?
His research focuses on applying naturallanguageprocessing techniques to extract information from unstructured clinical and medical texts, especially in low-resource settings. I love participating in various competitions involving deep learning, especially tasks involving naturallanguageprocessing or LLMs.
Foundation models are large AI models trained on enormous quantities of unlabeled data—usually through self-supervisedlearning. This process results in generalized models capable of a wide variety of tasks, such as image classification, naturallanguageprocessing, and question-answering, with remarkable accuracy.
Foundation models can be trained to perform tasks such as data classification, the identification of objects within images (computer vision) and naturallanguageprocessing (NLP) (understanding and generating text) with a high degree of accuracy. An open-source model, Google created BERT in 2018.
Training machine learning (ML) models to interpret this data, however, is bottlenecked by costly and time-consuming human annotation efforts. One way to overcome this challenge is through self-supervisedlearning (SSL). His specialty is NaturalLanguageProcessing (NLP) and is passionate about deep learning.
Data scientists and researchers train LLMs on enormous amounts of unstructured data through self-supervisedlearning. During the training process, the model accepts sequences of words with one or more words missing. The model then predicts the missing words (see “what is self-supervisedlearning?”

As an added inherent challenge, naturallanguageprocessing (NLP) classifiers are historically known to be very costly to train and require a large set of vocabulary, known as a corpus , to produce accurate predictions. Later versions of the GPT model, namely GPT3 and GPT4, are the engine that powers the ChatGPT application.
