- Title: Towards Attributions of Input Variables in a Coalition
- Abstract summary: We develop a new attribution method to explain the conflict between individual variables' attributions and their coalition's attribution.
First, we find that the Shapley value can be reformulated as the allocation of Harsanyi interactions encoded by the AI model.
Second, based the re-alloction of interactions, we extend the Shapley value to the attribution of coalitions.

- Abstract: This paper aims to develop a new attribution method to explain the conflict
between individual variables' attributions and their coalition's attribution
from a fully new perspective. First, we find that the Shapley value can be
reformulated as the allocation of Harsanyi interactions encoded by the AI
model. Second, based the re-alloction of interactions, we extend the Shapley
value to the attribution of coalitions. Third we ective. We derive the
fundamental mechanism behind the conflict. This conflict come from the
interaction containing partial variables in their coalition.

Conflicts could reflect the complexity of situations, changes that need to be explained and dealt with, difficulties in data annotation, and mistakes in generated outputs.
This survey categorizes these conflicts into three key areas: (1) natural texts on the web, where factual inconsistencies, subjective biases, and multiple perspectives introduce contradictions; (2) human-annotated data, where annotator disagreements, mistakes, and societal biases impact model training; and (3) model interactions, where hallucinations and knowledge conflicts emerge during deployment.
We highlight key challenges and future directions for developing conflict-aware NLP systems that can reason over and reconcile conflicting information more effectively

We present a framework aimed at optimizing the sequence for revealing coalition values in cooperative games.
Our contributions are threefold: (i) we study the individual players' optimistic completions of games with missing coalition values along with the arising gap, and investigate its analytical characteristics that facilitate more efficient optimization; (ii) we develop methods to minimize this gap over classes of games with a known prior by disclosing values of additional coalitions in both offline and online fashion; and (iii) we empirically demonstrate the algorithms' performance in practical scenarios.

We consider manipulations in the context of coalitional games, where a coalition aims to increase the total payoff of its members.
An allocation rule is immune to coalitional manipulation if no coalition can benefit from internal reallocation of worth.
For efficient allocation rules, reallocation-proofness is equivalent to constrained marginality.

We present a new algorithm for amortized inference in sparse probabilistic graphical models (PGMs)
Our approach is based on the observation that when the sampling of variables in a PGM is seen as a sequence of actions taken by an agent, sparsity of the PGM enables local credit assignment in the agent's policy learning objective.
We illustrate $Delta$-AI's effectiveness for sampling from synthetic PGMs and training latent variable models with sparse factor structure.
