Approximating Combinatorial Contracts with Arbitrary Costs
Xiaotie Deng, Hanyu Li, Chenghua Liu
We study single-agent combinatorial contracts under linear payments. Under a reward share , an agent chooses a subset of hidden actions, generating reward …
Cardinality-Constrained Randomized Assortments with Balanced Market Share
Xiaotie Deng, Hanyu Li, Chenghua Liu
Assortment optimization asks a seller which of products to display to each customer. Under the multinomial-logit (MNL) model, a revenue-maximizing policy may concentrate most p…
RepoMirage: Probing Repository Context Reasoning in Code Agents with Perturbations
Hanyu Li, Yichi Zhang, Speed Zhu +3
Code agents are currently having skillful performance on repository-level software engineering benchmarks, but it remains unclear whether success on end-to-end tasks such as issue…
An Information-Theoretic Criterion for Efficient Data Synthesis
Hanyu Li, Zhengqi Sun, Xiaotie Deng
Synthetic data becomes crucial for large language model training, but its effectiveness is highly inconsistent. We provide an information-theoretic account of this inconsistency: s…
