TEMPER: Tensorized Efficient Manifold-constrained Parameterization for Expressive Residual Routing

Yuxuan Gu, Wuyang Zhou, Huijun Xing +1

Residual connections rely on a static residual pathway, and are essential for training deep neural networks. Hyper-connections (HC) increase the expressivity of residual routing by…

Beyond Co-Movement: Locality by Exposures Enables a Joint Factor-Graph Framework for Portfolio Diversification

Sara Chehab, Giorgos Iacovides, Parisa Yazdanparast +1

Current portfolio construction methods are either agnostic to the effects of idiosyncratic shocks (standard factor models) or to the latent data structure driving systematic return…

Tensorizing Engram: Sharing Latents Across N-Gram Embeddings is Beneficial in LLMs

Wuyang Zhou, Yuxuan Gu, Giorgos Iacovides +3

Modern language models represent text using discrete token-level embeddings, which forces recurring multi-token patterns to be learned implicitly across Transformer layers. Both Ov…

KromHC: Manifold-Constrained Hyper-Connections with Kronecker-Product Residual Matrices

Wuyang Zhou, Yuxuan Gu, Giorgos Iacovides +1

The success of Hyper-Connections (HC) in neural networks (NN) has also highlighted issues related to training instability and restricted scalability. The Manifold-Constrained Hyper…

TeRA: Vector-based Random Tensor Network for High-Rank Adaptation of Large Language Models

Yuxuan Gu, Wuyang Zhou, Giorgos Iacovides +1

Parameter-Efficient Fine-Tuning (PEFT) methods, such as Low-Rank Adaptation (LoRA), have significantly reduced the number of trainable parameters needed in fine-tuning large langua…
