The Sparsity Whisperer
Linghao Kong, Inimai Subramanian, Micah Adler +3
Pruning reduces the inference cost of large language models, but existing criteria primarily preserve large activations or reconstruct layer outputs. We argue that this overlooks a…
Expand Neurons, Not Parameters
Linghao Kong, Inimai Subramanian, Yonadav Shavit +3
This work demonstrates how increasing the number of neurons in a network without increasing its total number of non-zero parameters improves performance. We show that this gain cor…
An Interpretable Latency Model for Speculative Decoding in LLM Serving
Linghao Kong, Megan Flynn, Michael Peng +3
Speculative decoding (SD) accelerates large language model (LLM) inference by using a smaller draft model to propose multiple tokens that are verified by a larger target model in p…
Negative Pre-activations Differentiate Syntax
Linghao Kong, Angelina Ning, Micah Adler +1
Modern large language models increasingly use smooth activation functions such as GELU or SiLU, allowing negative pre-activations to carry both signal and gradient. Nevertheless, m…
Wasserstein Distances, Neuronal Entanglement, and Sparsity
Shashata Sawmya, Linghao Kong, Ilia Markov +2
Disentangling polysemantic neurons is at the core of many current approaches to interpretability of large language models. Here we attempt to study how disentanglement can be used…
