Evaluating ChatGPT’s Zero-Shot Learning Ability on 20 Popular NLP Datasets

Do you want to know how large language models (LLMs) can be used to perform NLP tasks without relying on training data? Have you been curious about ChatGPT, the OpenAI model developed using reinforcement learning? If so, then this blog post is just for you! In this post, we will explore the capabilities of ChatGPT for zero-shot learning, and how it compares to the state-of-the-art GPT-3.5 model. Read on to find out how ChatGPT can be used to perform various NLP tasks, and how it can help close the gap in the literature.

Sub-headline 1: Conditioning the Model on Suitable Prompts
LLMs have been proven to do a number of NLP tasks with zero-shot learning, meaning they do not rely on training data for a given downstream job. ChatGPT was developed using reinforcement learning to train a GPT-3.5 series model based on user input (RLHF). RLHF uses a three-stage process of supervised language model training, human preference comparison data collection and reward model training, and reinforcement learning-based language model optimization.

Sub-headline 2: Comparing Capabilities with GPT-3.5
To find out the capabilities of ChatGPT, the researchers tested it on a wide range of NLP datasets covering 7 illustrative task categories, including reasoning, natural language inference, question answering (reading comprehension), dialogue, summarization, named entity recognition, and sentiment analysis. The findings show that ChatGPT is better at reasoning-heavy tasks like finding logical links between text pairs and natural language inference tasks like question responding (reading comprehension). It is also better at classifying entailment rather than non-entailment. However, ChatGPT is worse than GPT-3.5 when used for summarization, as the zero-shot instruction’s explicit length limitation harms the summarization quality.

Sub-headline 3: Closing the Gap in the Literature
The team hopes their work will inspire other researchers to explore ways to put ChatGPT’s reasoning and dialogue capabilities to use in NLP applications and overcome the limits of generalist models in areas where they’ve historically struggled.
