Continuous diffusion models for language, after a period of dormancy, are experiencing a resurgence. While discrete diffusion methods previously dominated, recent developments suggest a shift. This comeback is marked by several papers published in late 2022, including Diffusion-LM, DiffuSeq 16, SSD-LM 17, Difformer 18, SeqDiffuSeq 19, GENIE 20, LD4LG 21, self-conditioned embedding diffusion (SED) 22, and continuous diffusion for categorical data (CDCD) 23. The approach involves lifting the corruption process from discrete input space into a continuous embedding space.

The "ChatGPT Work Tool and Skill Reference" outlines various functionalities, including spreadsheet manipulation and data analytics. The "Spreadsheets" skill is used for creating, modifying, analyzing, visualizing, or working with spreadsheet files such as `.xlsx`, `.xls`, `.csv`, `.tsv`, or Google Sheets artifacts, encompassing formulas, formatting, charts, tables, and recalculation. Additionally, the `data-analytics:create-data-context` skill is for creating, updating, inspecting, or repairing Data Analytics semantic layers, specifically when a user requests to save data context or create a semantic layer for future Data Analytics work.

This article explores diffusion language models as an alternative to autoregressive models for discrete data like text. Autoregressive models generate tokens sequentially, leading to limitations such as no error correction, slow generation, and causal attention. Diffusion models, conversely, generate entire sequences at once, iteratively refining them. This approach offers advantages like adjustable speed-quality trade-offs, built-in error correction, and bidirectional context awareness, potentially leading to more intelligent models.
