This research paper introduces Large Concept Models (LCMs), a novel approach to language modeling that operates on sentence embeddings instead of individual tokens. LCMs aim to mimic human-like abstract reasoning by processing higher-level semantic representations, improving long-form text generation and zero-shot cross-lingual performance. The authors explore various LCM architectures, including...

Ref: https://arxiv.org/abs/2112.04482 The document introduces FLAVA, a foundational vision and language model that excels in vision, language, and multimodal tasks. Unlike previous models often focusing on specific modalities or employing either contrastive or multi-modal approaches but not both, FLAVA uses a unified transformer architecture and a novel pretraining scheme. This scheme leverages bo...

Ref: https://arxiv.org/abs/2004.05150 The paper introduces Longformer, a Transformer model designed to efficiently process long sequences. It addresses the quadratic complexity of standard self-attention by using a linear-scaling mechanism combining local windowed attention and task-motivated global attention. The authors demonstrate Longformer's effectiveness on character-level language modeling...

Ref: https://arxiv.org/abs/2001.08361 This research paper empirically investigates scaling laws for Transformer-based language models. The authors find that performance improves predictably with increases in model size, dataset size, and training compute, following power-law relationships across several orders of magnitude. Other architectural details have minimal impact. Optimally efficient train...
