Alex Warstadt, Alicia Parrish, Haokun Liu, Anhad Mohananey, Wei Peng, Sheng-Fu Wang, Samuel R. Bowman
| Challenge: | Recent studies have examined how linguistic knowledge of language models (LMs) varies across English phenomena. |
| Approach: | They propose a benchmark to evaluate linguistic knowledge of language models on major grammatical phenomena in English. |
| Outcome: | The proposed benchmark evaluates the linguistic knowledge of language models on major grammatical phenomena in English. |
How Much Do Language Models Copy From Their Training Data? Evaluating Linguistic Novelty in Text Generation Using RAVEN (2023.tacl-1)
Copied to clipboard
| Challenge: | Current language models generate high-quality text, but are they copying it or have they learned generalizable linguistic abstractions? |
| Approach: | They propose a suite of analyses for assessing the novelty of generated text . they focus on sequential structure (n-grams) and syntactic structure (syntactical structure). |
| Outcome: | The proposed model-generated text is as novel as the baseline human-generated model- generated text, but it is copied substantially, the authors show . |
Approximating Two-Layer Feedforward Networks for Efficient Transformers (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Recent work uses sparse Mixtures of Experts (MoEs) to build resource-efficient large language models. |
| Approach: | They propose a general framework that unifies various methods to build two-layer NNs . they propose methods to improve both MoEs and PKMs based on their results . |
| Outcome: | The proposed framework improves both MoEs and product-key memories (PKMs) it shows that MoE's are competitive with dense Transformer-XL on two different scales while being much more resource efficient. |
Transformer-XL: Attentive Language Models beyond a Fixed-Length Context (P19-1)
Copied to clipboard
| Challenge: | Term memory networks (RNNs) are difficult to optimize due to gradient vanishing and explosion. |
| Approach: | They propose a neural architecture Transformer-XL that enables learning dependency beyond a fixed length without disrupting temporal coherence. |
| Outcome: | The proposed method improves state-of-the-art performance on short and long sequences and generates coherent, novel text articles with thousands of tokens. |
Wiki-40B: Multilingual Language Model Dataset (2020.lrec-1)
Copied to clipboard
| Challenge: | We propose a new multilingual language model benchmark that is composed of 40+ languages spanning several scripts and linguistic families. |
| Approach: | They propose a multilingual language model benchmark composed of 40+ languages . they train monolingual causal language models using a state-of-the-art model . |
| Outcome: | The proposed model is composed of 40+ languages spanning several scripts and linguistic families. |
TRAMS: Training-free Memory Selection for Long-range Language Modeling (2023.findings-emnlp)
Copied to clipboard
| Challenge: | Existing methods like Transformer-XL are plagued by ineffective memory selections due to the high number of tokens involved in attention calculation. |
| Approach: | They propose a plug-and-play strategy that selects tokens participating in attention calculation based on one simple metric and ignores the other ones. |
| Outcome: | The proposed strategy keeps tokens with high attention scores and ignores the other ones on word-level and character-level benchmarks without additional training or adding additional parameters. |
Do Transformers Need Deep Long-Range Memory? (2020.acl-main)
Copied to clipboard
| Challenge: | Deep attention models have advanced the modelling of sequential data across many domains. |
| Approach: | They propose to use a Transformer augmented with a long-range memory to model sequential data across many domains. |
| Outcome: | The Transformer-XL has a long-range memory at every layer of the network, rendering its state thousands of times larger than RNN predecessors. |
