A Survey of Large Language Models
This survey highlights the complexity of language and the challenge of developing AI algorithms capable of understanding and generating language. Over the past two decades, language modelling has evolved from statistical models to neural models, with recent advances in pre-trained language models (PLMs) that use Transformer models and large-scale corpora for improved language understanding and… Continue reading A Survey of Large Language Models
Learning to Quantify
This book provides an introduction and an overview of learning to quantify (a.k.a. “quantification”), the task of training, by means of supervised learning, estimators of class proportions in unlabelled data. In data science, learning to quantify is a task of its own, related to classification but different from it, since estimating class proportions by simply… Continue reading Learning to Quantify
