LMs are used to process text from many topics, styles, dialects, etc., but how well do they do? 📈 Evaluating perplexity on just one corpus like C4 doesn't tell the whole story 📉 ✨📃✨ We introduce Paloma, a benchmark of 585 domains from NY Times to r/depression on Reddit.

Perplexity macro averaged over any domains within each of the 18 top-level data sources in Paloma, using baselines with pretraining controls including decontamination. Evaluating on one monolithic corpus, such as C4, does not tell the complete story of model fit. Paloma lets us see when trends differ from one distribution of language to another. For instance, the 3 baselines trained on only Common Crawl data (C4, mC4-en, Falcon-RefinedWeb) exhibit high perplexity, sometimes with non-monotonic scaling over tokens seen, on specific evaluation sources such as The Pile, Dolma, and Dolma-100-Programming-Languages.

Very happy (and proud b/c it took a loooong time to finalise this paper) to share new research, together with Alejandro Ecker, on how local politicians in 🇩🇪 allocate portfolios. In short, they behave like their counterparts at the federal & state levels: both quant. & qual. considerations matter!

Online first & part of the Symposium "Competition & Cooperation at the Local Level": "Equitability or proportionality? Local-level portfolio allocation in Germany" by Alejandro Ecker & @martingross.bsky.social doi.org/10.1080/0140... #PoliSky

Abstract of the paper "Equitability or proportionality? Local-level portfolio allocation in Germany" by Alejandro Ecker & Martin Gross:

This study addresses a fundamental question in democratic systems: how do government parties allocate executive portfolios? While extensive research has tackled this question at the national and regional levels, there is a notable gap in understanding the local level. This study addresses this issue by analysing portfolio allocation at the local level in Germany. Both the quantitative aspect, focusing on the number of portfolios, and the qualitative aspect, examining the distribution across policy fields, are explored. The findings reveal a highly politicised approach to portfolio allocation at the local level. Local political actors prioritise proportional allocations over equitable distributions. Additionally, local parties seek portfolios aligned to policy issue areas that feature prominently in their election manifestos. This study sheds light on the intricacies of local-level portfolio distribution, contributing to a more comprehensive understanding of local democratic governance.

Dive into the world of multilingual text analysis? @haukelicht.bsky.social and I wrote this paper as a first go-to resource for a comprehensive overview of research design considerations. Big thanks to the editors @marikenvelden.bsky.social, Martijn Schoonvelde, Christian Baden of the special issue!
