    Study Notes

    Understanding Prompt-Tuning: A Comprehensive Overview

    • Prompt-Tuning is a fine-tuning paradigm that aims to address the overfitting problem that occurs due to the introduction of additional parameters during fine-tuning, which can lower a model's generalization ability.

    • Pre-training language models, such as GPT, ELMO, and BERT, have become popular in recent years and are categorized as either unidirectional or bidirectional models.

    • BERT and its variants are the most commonly used language models, with the Transformer model as their main structure, which is fully constructed using attention mechanisms that allow for parallel computing and alleviate the problem of long-distance dependency and gradient vanishing.

    • The classic pre-training tasks include masked language modeling (MLM), next sentence prediction (NSP), and others, with MLM being a self-supervised training method that uses a fixed replacement policy to obtain self-supervised corpus and train the model to predict masked tokens.

    • WWM (whole word masking) and MLM-M (masked language modeling-maximization) are two popular variations of the MLM task that have been proposed to improve the performance of the original MLM task.

    • Prompt-Tuning aims to bridge the gap between fine-tuning and pre-training by incorporating prompts that are specific to the downstream task during fine-tuning.

    • Prompt-Tuning can be implemented in different ways, such as prefix-tuning, infix-tuning, and suffix-tuning, depending on where the prompts are added to the input sequence.

    • Prompt-Tuning has shown promising results in various NLP tasks, such as sentiment analysis, question answering, and text classification, and has outperformed traditional fine-tuning methods.

    • Prompt-Tuning can be used for both supervised and unsupervised tasks, and can be applied to different types of models, such as BERT, GPT, and T5.

    • Prompt-Tuning also allows for the generation of synthetic data by generating prompts that perturb the original input sequence and produce new samples that can be used for training.

    • Prompt-Tuning can be combined with other techniques, such as adversarial training and data augmentation, to further improve model performance and robustness.

    • Prompt-Tuning is a promising direction for future research in NLP and can potentially lead to the development of more effective and efficient models for various downstream tasks.Overview of Pre-training and Fine-tuning in NLP

    • BERT and WWM are pre-training tasks that involve masking tokens, but WWM requires masking of complete words, while BERT only masks word pieces.

    • ERNIE-BAIDU introduced EMR, which masks entire entities in a text using a knowledge base, rather than individual tokens or characters.

    • NSP is a pre-training task in BERT that involves determining the relationship between two sentences, with three possible outcomes: entailment, contradiction, and neutral.

    • NSP can be generated through self-supervised learning on large unsupervised corpora, by randomly selecting a sentence from the same article as the premise, and a sentence from a different article as the contradiction.

    • ALBERT and RoBERTa models have removed NSP from their pre-training tasks due to its limited positive impact on experimental results.

    • Fine-tuning involves training a pre-trained language model on specific downstream NLP tasks, such as single-text classification, sentence-pair classification, and span text prediction.

    • Single-text classification involves classifying a single text, such as short/long text classification, intent recognition, sentiment analysis, and relation extraction.

    • Sentence-pair classification involves determining the relationship between two texts, such as semantic inference, text matching, and retrieval.

    • Span text prediction involves predicting a reliable sequence of characters in a passage based on a given query, such as extractive reading comprehension, entity extraction, and extractive summarization.

    • Single-token classification involves tasks such as sequence labeling, cloze tests, and spelling correction, where the pre-trained model predicts outcomes for individual tokens.

    • In fine-tuning, the pre-trained model's last layer's hidden state vector is fed into a new classifier MLP and trained with cross-entropy loss.

    • Fine-tuning strategies vary depending on the nature of the downstream task, and the pre-trained model's architecture and size can affect performance.Overview of Natural Language Processing Tasks and Techniques

    • Natural Language Processing (NLP) involves using computers to process and analyze human language.

    • NLP tasks include text classification, named entity recognition, sentiment analysis, machine translation, and more.

    • Pre-training language models, such as BERT, have improved the performance of NLP tasks.

    • One pre-training technique is Masked Language Modeling (MLM), where certain words in a text are masked and the model predicts the missing word.

    • Another pre-training technique is Next Sentence Prediction (NSP), where the model predicts whether two sentences are related or not.

    • Sequence labeling involves assigning labels to each token in a text, such as part-of-speech tagging, slot filling, syntax parsing, and entity recognition.

    • Cloze tests involve predicting missing words in a text, similar to MLM.

    • Spell checking involves identifying and correcting spelling errors in a text.

    • Text generation tasks include generating summaries, machine translations, and answering questions.

    • Pre-trained language models can be used for text generation tasks, either through autoregressive or non-autoregressive methods.

    • Autoregressive models generate text one word at a time, while non-autoregressive models generate all the words at once.

    • Examples of NLP benchmarks include CoNLL-2003 for named entity recognition and GLUE for text classification.
