There have been quite a few interesting Kaggle competitions in recent years, as well as other interesting ML/data science competitions on other platforms. Platforms like Kaggle, DrivenData, Zindi, AIcrowd, CodaLab and others are running dozens-hundreds of competitions a year in total, including ones linked to top academic conferences. One interesting recent one is this one on LLM efficiency - trying to see to what extent people can fine-tune an LLM with just 1GPU and 24h: https://llm-efficiency-challenge.github.io/ https://llm-efficiency-challenge.github.io/ Or the Makridakis series of challenges, running since the 80s, which are a great testbed for time-series models (the 6th one finished just last year): https://mofc.unic.ac.cy/the-m6-competition/ https://mofc.unic.ac.cy/the-m6-competition/
