CT Open: An Open-Access, Uncontaminated, Live Platform for the Open Challenge of Clinical Trial Outcome Prediction

Jianyou Wang, Youze Zheng, Longtian Bao +11

Scientists have long sought to accurately predict outcomes of real-world events before they happen. Can AI systems do so more reliably? We study this question through clinical tria…

Quiet Feature Learning in Algorithmic Tasks

Prudhviraj Naidu, Zixian Wang, Leon Bergen +1

We train Transformer-based language models on ten foundational algorithmic tasks and observe pronounced phase transitions in their loss curves that deviate from established power-l…

EvidenceBench: A Benchmark for Extracting Evidence from Biomedical Papers

Jianyou Wang, Weili Cao, Kaicheng Wang +13

We study the task of automatically finding evidence relevant to hypotheses in biomedical papers. Finding relevant evidence is an important step when researchers investigate scienti…

Local Enumeration: The Not-All-Equal Case

Mohit Gurumukhani, Ramamohan Paturi, Michael Saks +1

Gurumukhani et al. (CCC'24) proposed the local enumeration problem Enum(k, t) as an approach to break the Super Strong Exponential Time Hypothesis (SSETH): for a natural number …

On Extremal Properties of k-CNF: Capturing Threshold Functions

Mohit Gurumukhani, Marvin Künnemann, Ramamohan Paturi

We consider a basic question on the expressiveness of -CNF formulas: How well can -CNF formulas capture threshold functions? Specifically, what is the largest number of assig…

Measuring Risk of Bias in Biomedical Reports: The RoBBR Benchmark

Jianyou Wang, Weili Cao, Longtian Bao +6

Systems that answer questions by reviewing the scientific literature are becoming increasingly feasible. To draw reliable conclusions, these systems should take into account the qu…

Dissociation of Faithful and Unfaithful Reasoning in LLMs

Evelyn Yee, Alice Li, Chenyu Tang +3

Large language models (LLMs) often improve their performance in downstream tasks when they generate Chain of Thought reasoning text before producing an answer. We investigate how L…

On the Fine-grained Complexity of One-Dimensional Dynamic Programming

Marvin Künnemann, Ramamohan Paturi, Stefan Schneider

In this paper, we investigate the complexity of one-dimensional dynamic programming, or more specifically, of the Least-Weight Subsequence (LWS) problem: Given a sequence of da…
