The future is different: Large pre-trained language models fail in prediction tasks

no code implementations1 Nov 2022 Kostadin Cvejoski, Ramsés J. Sánchez, César Ojeda

Our models display performance drops of only about 40% in the worst cases (2% in the best ones) when predicting the popularity of future posts, while using only about 7% of the total number of parameters of LPLM and providing interpretable representations that offer insight into real-world events, like the GameStop short squeeze of 2021
