How Prompts Move Language Model Behavior: Frames, Salience, and Construal as Semantic Control
Dongseok Kim, Hyoungsun Choi, Mohamed Jismy Aashik Rasool +1
Prompt engineering is widely used to shape large language model behavior, yet it is often treated as a practical heuristic rather than as a form of natural-language control. This p…
CLAPS: Aleatoric-Epistemic Scaling via Last-Layer Laplace for Conformal Regression
Dongseok Kim, Hyoungsun Choi, Mohamed Jismy Aashik Rasool +1
Conformal regression provides finite-sample marginal coverage, but interval efficiency depends on how uncertainty is allocated across inputs. We propose \emph{Conformal Laplace-Awa…
CUBE: Contrastive Understanding by Balanced Experiments
Dongseok Kim, Hyoungsun Choi, Mohamed Jismy Aashik Rasool +1
We introduce CUBE, Contrastive Understanding by Balanced Experiments, to estimate main effects and pairwise Banzhaf interactions over a fixed two-state probe space using shared bal…
Gaming and Cooperation in Federated Learning: What Can Happen and How to Monitor It
Dongseok Kim, Hyoungsun Choi, Mohamed Jismy Aashik Rasool +1
The success of federated learning (FL) ultimately depends on how strategic participants behave under partial observability, yet most formulations still treat FL as a static optimiz…
A Ridge Too Far: Correcting Over-Shrinkage via Negative Regularization
Dongseok Kim, Gisung Oh
Conventional regularization is designed to control variance, but in small-data regression it can also aggravate underfitting when predictive signal is concentrated in weak directio…
