Mixture of Mini Experts: Overcoming the Linear Layer Bottleneck in Multiple Instance Learning

ICLR 2026poster

Multiple Instance Learning (MIL) is the predominant approach for classifying gigapixel whole-slide images in computational pathology. MIL follows a sequence of 1) extracting patch features, 2) applying a linear layer to obtain task-specific patch features, and 3) aggregating the patches into a slide…

Do Multiple Instance Learning Models Transfer?

ICML 2025spotlight

Multiple Instance Learning (MIL) is a cornerstone approach in computational pathology for distilling embeddings from gigapixel tissue images into patient-level representations to predict clinical outcomes. However, MIL is frequently challenged by the constraints of working with small, weakly-supervi…

HEST-1k: A Dataset For Spatial Transcriptomics and Histology Image Analysis

NeurIPS 2024spotlight

Spatial transcriptomics enables interrogating the molecular composition of tissue with ever-increasing resolution and sensitivity. However, costs, rapidly evolving technology, and lack of standards have constrained computational methods in ST to narrow tasks and small cohorts. In addition, the under…

Morphological Prototyping for Unsupervised Slide Representation Learning in Computational Pathology

CVPR 2024poster

Representation learning of pathology whole-slide images (WSIs) has been has primarily relied on weak supervision with Multiple Instance Learning (MIL). However the slide representations resulting from this approach are highly tailored to specific clinical tasks which limits their expressivity and ge…

Multimodal Prototyping for cancer survival prediction

ICML 2024poster

Multimodal survival methods combining gigapixel histology whole-slide images (WSIs) and transcriptomic profiles are particularly promising for patient prognostication and stratification. Current approaches involve tokenizing the WSIs into smaller patches ($>10^4$ patches) and transcriptomics into ge…

Transcriptomics-guided Slide Representation Learning in Computational Pathology

CVPR 2024poster

Self-supervised learning (SSL) has been successful in building patch embeddings of small histology images (e.g. 224 x 224 pixels) but scaling these models to learn slide embeddings from the entirety of giga-pixel whole-slide images (WSIs) remains challenging. Here we leverage complementary informati…

High-Dimensional Sparse Bayesian Learning without Covariance Matrices

ICASSP 2022accepted

Sparse Bayesian learning (SBL) is a powerful framework for tackling the sparse coding problem. However, the most popular inference algorithms for SBL become too expensive for high-dimensional settings, due to the need to store and compute a large covariance matrix. We introduce a new inference schem…

PLSO: A generative framework for decomposing nonstationary time-series into piecewise stationary oscillatory components

UAI 2021poster

To capture the slowly time-varying spectral content of real-world time-series, a common paradigm is to partition the data into approximately stationary intervals and perform inference in the time-frequency domain. However, this approach lacks a corresponding nonstationary time-domain generative mode…

Channel-Attention Dense U-Net for Multichannel Speech Enhancement

ICASSP 2020accepted

Supervised deep learning has gained significant attention for speech enhancement recently. The state-of-the-art deep learning methods perform the task by learning a ratio/binary mask that is applied to the mixture in the time-frequency domain to produce the clean speech. Despite the great performanc…
