Multitask Prompted Training Enables Zero-Shot Task Generalization

Overview

A community framework that converts supervised natural language tasks into human-readable prompted forms for explicit multitask learning. It enables zero-shot generalization by training a single model on many prompted datasets with diverse wording, rather than relying on implicit multitask learning during pretraining.

• Evaluating the effect of prompt wording on zero-shot task performance
• Systematically mapping diverse supervised tasks into a unified prompt format

Notes

A community framework that converts supervised natural language tasks into human-readable prompted forms for explicit multitask learning.

Use cases

• Building a zero-shot model by training on a collection of prompted datasets
• Evaluating the effect of prompt wording on zero-shot task performance
• Systematically mapping diverse supervised tasks into a unified prompt format

Pros

• Directly induces zero-shot generalization through explicit multitask training
• Leverages existing supervised datasets by converting them into prompted forms
• Supports multiple prompts per dataset to study wording sensitivity

Cons

• Requires converting and curating large collections of tasks into prompts
• May not match the zero-shot performance of implicit multitask learning in pretrained models
• Performance depends on the quality and diversity of prompt phrasing
