Towards Understanding Text Hallucination of Diffusion Models via Local Generation Bias
Score-based diffusion models have achieved incredible performance in generating realistic images, audio, and video data.
MATH-Perturb: Benchmarking LLMs' Math Reasoning Abilities against Hard Perturbations
This issue is amplified when using original problems for in-context learning.
The Marginal Value of Momentum for Small Learning Rate SGD
Momentum is known to accelerate the convergence of gradient descent in strongly convex settings without stochastic gradient noise.
Gradient Descent on Two-layer Nets: Margin Maximization and Simplicity Bias
The current paper is able to establish this global optimality for two-layer Leaky ReLU nets trained with gradient flow on linearly separable and symmetric data, regardless of the width.
Going Beyond Linear RL: Sample Efficient Neural Function Approximation
While the theory of RL has traditionally focused on linear function approximation (or eluder dimension) approaches, little is known about nonlinear RL with neural net approximations of the Q functions.
Optimal Gradient-based Algorithms for Non-concave Bandit Optimization
This work considers a large family of bandit problems where the unknown underlying reward function is non-concave, including the low-rank generalized linear bandit problems and two-layer neural network with polynomial activation bandit problem.
Mildly Overparametrized Neural Nets can Memorize Training Data Efficiently
It has been observed \citep{zhang2016understanding} that deep neural networks can memorize: they achieve 100\% accuracy on training data.
