A QLoRA vs Standard Finetuning Experimental Setup Details A.1 Hyperparameters for QL
We do a hyperparameter search for LoRA over the following variables: LoRA dropout { 0.0, 0.05, LoRA α is always proportional to the learning rate. We find that LoRA dropout 0.05 is useful for small models (7B, 13B), but not for larger models (33B, We use the same preprocessing of the Super-Natural Instruction dataset as Wang et al. RA finetuning experiments outlined in Section 5. This limits the dataset to 9,209 examples. HH-RLHF This is a human preference dataset about helpfulness and harmlessness.

Teen discovers Australia's oldest dinosaur fossil--almost 70 years ago
Science Dinosaurs Teen discovers Australia's oldest dinosaur fossil--almost 70 years ago An early sauropodomorph likely made the 230-million-year-old footprint. Breakthroughs, discoveries, and DIY tips sent six days a week. In 1958, an Australian teenager named Bruce Runnegar uncovered a mysterious dinosaur footprint during a visit to a quarry with school friends. He kept the fossil for years, eventually becoming a paleontologist himself. Over six decades later, the prehistoric print is now ready for its close-up.

The app, developed by researchers from the University of Edinburgh, has been used to analyse footprints made by dinosaurs more than 200 million years ago. The results show that several tracks share'uncanny' features with both extinct and modern birds. According to the researchers, this suggests that birds could have originated 60 million years earlier than we thought.
