Decoupled DMD: CFG Augmentation as the Spear, Distribution Matching as the Shield

ICLR 2026poster

Diffusion model distillation has emerged as a powerful technique for creating efficient few-step and single-step generators. Among these, Distribution Matching Distillation (DMD) and its variants stand out for their impressive performance, which is widely attributed to their core mechanism of matchi…

Bayesian nonparametric (non-)renewal processes for analyzing neural spike train variability

NeurIPS 2023poster

Neural spiking activity is generally variable, non-stationary, and exhibits complex dependencies on covariates, such as sensory input or behavior. These dependencies have been proposed to be signatures of specific computations, and so characterizing them with quantitative rigor is critical for under…

Coupling Artificial Neurons in BERT and Biological Neurons in the Human Brain

AAAI 2023technical

Linking computational natural language processing (NLP) models and neural responses to language in the human brain on the one hand facilitates the effort towards disentangling the neural representations underpinning language perception, on the other hand provides neurolinguistics evidence to evaluat…

Fine-grained Artificial Neurons in Audio-transformers for Disentangling Neural Auditory Encoding

ACL 2023findings

The Wav2Vec and its variants have achieved unprecedented success in computational auditory and speech processing. Meanwhile, neural encoding studies that integrate the superb representation capability of Wav2Vec and link those representations to brain activities have provided novel insights into a f…

A universal probabilistic spike count model reveals ongoing modulation of neural variability

NeurIPS 2021poster

Neural responses are variable: even under identical experimental conditions, single neuron and population responses typically differ from trial to trial and across time. Recent work has demonstrated that this variability has predictable structure, can be modulated by sensory input and behaviour, and…
