Meanwhile, the span corruption objective is a data transformation that corrupts spans (a subsequence of tokens in the input), replacing them with mask tokens that are shifted to the targets. Most common paradigms to build and train language models use either autoregressive decoder-only architectures (e.g., PaLM or GPT-3), where the model is trained to predict the next word for a given prefix phrase, or span corruption-based encoder-decoder architectures (e.g., T5, ST-MoE), where the training objective is to recover the subset of words masked out of the input. In the plot below, we show baseline objective functions on different tasks compared to UL2: CausalLM (referred to as GPT-like), PrefixLM, Span Corrupt (also referred to as T5 in the plot), and a baseline objective function proposed by UniLM. [2205.05131] UL2: Unifying Language Learning Paradigms - arXiv.org Finally, we show that UL2 20B works well with chain-of-thought . . [PDF] Unifying Language Learning Paradigms | Semantic Scholar We use these objectives for training decoder only architectures (green) and encoder-decoder architectures (blue) and evaluate different combinations of objective functions and architectures on two main sets of tasks: For most of the existing language learning paradigms, there is a trade-off between the quality of the model on these two sets of tasks. In the table below, we show that for UL2, CoT prompting outperforms standard prompting on math word problems with a range of difficulties (GSM8K, SVAMP, ASDiv, AQuA, and MAWPS). This paper presents a unified framework for pre-training models that are universally effective across datasets and setups. The standard Causal Language modeling objective (CausalLM) is trained to predict full sequence lengths and so, only recognizes tokens in the target output. on SCROLLS. task.

Sutowo Wong on LinkedIn: UL2: Unifying Language Learning Paradigms Update #35: AI Bill of Rights and Unifying Language Learning Paradigms Our model also achieve strong results at in-context learning, outperforming 175B GPT-3 on zero-shot SuperGLUE and tripling the performance of T5-XXL on one-shot summarization. It is shown that pretraining with a BART-style denoising loss directly on simplied HTML provides highly effective transfer for a wide range of end tasks and supervision levels, and that HTLM is highly effective at autoprompting itself. To train language models, UL2 casts a variety of goal functions as denoising tasks, where the model must reconstruct lost portions of the input. We then propose Mixture-of-Denoisers (MoD), a pre-training objective that combines diverse pre-training paradigms together. Yi Tay, Mostafa Dehghani, Vinh Q.

Google AI Introduces Unified Language Learner (UL2 20B): A Breakthrough We furthermore introduce a notion of mode switching, wherein downstream fine-tuning is associated with specific pre-training schemes. A large-scale evaluation of modeling choices and their impact on zero-shot generalization of large pretrained Transformer language models focuses on text-to-text models and shows that causal decoder-only models trained on an autoregressive language modeling objective exhibit the strongest zero- shot generalization after purely self-supervised pretraining. Open Publishing. We conduct extensive ablative experiments to compare multiple pre-training objectives and find that our method pushes the Pareto-frontier by outperforming T5 and/or GPT-like models across multiple diverse setups. The model is conditioned on different forms of input to predict target tokens. This enables an open avenue for researchers to conduct research on CoT prompting and reasoning at an accessible scale.

We also show that self-consistency further improves performance. On the other hand, autoregressive language models are great for open-ended generation (e.g., dialog generation with LaMDA) and prompt-based learning (e.g., in-context learning with PaLM), but may perform suboptimally on fine-tuning tasks.

To this end, different objectives utilize different properties of the inputs. Common objective functions for training language models can mostly be framed as learning data transformations that map inputs to targets. UL2 leverages the strengths of each of these objective functions through a framework that generalizes over each of them, which enables the ability to reason and unify common pre-training objectives. In the table below, we compare UL2 with other state-of-the-art models (e.g, T5 XXL and PaLM) for few-shot prompting on the XSUM summarization dataset.
