Inference-Time Nash Alignment
Hadi Hosseini, Debmalya Mandal, Duohan Zhang
Preference-based fine-tuning methods such as RLHF and DPO require substantial compute and large preference datasets. They also need direct access to the model parameters which are…
The Landscape of Almost Equitable Allocations
Hadi Hosseini, Vishwa Prakash HV, Aditi Sethia +1
Equitability is a fundamental notion in fair division which requires that all agents derive equal value from their allocated bundles. We study, for general (possibly non-monotone)…
Fair Societies: Algorithms for House Allocations
Hadi Hosseini, Sanjukta Roy, Aditi Sethia
House Allocations concern with matchings involving one-sided preferences, where houses serve as a proxy encoding valuable indivisible resources (e.g. organs, course seats, subsidiz…
Equitable Allocations of Mixtures of Goods and Chores
Hadi Hosseini, Aditi Sethia
Equitable allocation of indivisible items involves partitioning the items among agents such that everyone derives (almost) equal utility. We consider the approximate notion of \tex…
Strategyproof Matching of Roommates and Rooms
Hadi Hosseini, Shivika Narang, Sanjukta Roy
We initiate the study of matching roommates and rooms wherein the preferences of agents over other agents and rooms are complementary and represented by Leontief utilities. In this…
Bandit Learning in Matching Markets: Utilitarian and Rawlsian Perspectives
Hadi Hosseini, Duohan Zhang
Two-sided matching markets have demonstrated significant impact in many real-world applications, including school choice, medical residency placement, electric vehicle charging, ri…
Putting Gale & Shapley to Work: Guaranteeing Stability Through Learning
Hadi Hosseini, Sanjukta Roy, Duohan Zhang
Two-sided matching markets describe a large class of problems wherein participants from one side of the market must be matched to those from the other side according to their prefe…
The Degree of Fairness in Efficient House Allocation
Hadi Hosseini, Medha Kumar, Sanjukta Roy
The classic house allocation problem is primarily concerned with finding a matching between a set of agents and a set of houses that guarantees some notion of economic efficiency (…
Almost Envy-Freeness under Weakly Lexicographic Preferences
Hadi Hosseini, Aghaheybat Mammadov, Tomasz Wąs
In fair division of indivisible items, domain restriction has played a key role in escaping from negative results and providing structural insights into the computational and axiom…
