Random Sum-Product Networks: A Simple and Effective Approach to Probabilistic Deep Learning
Is structure learning even necessary? By generating overparametrised, random model structures for sum-product networks, a class of tractable probabilistic graphical models, Peharz et al. manage to obtain models that are competitive with far more complex generative learning approaches as well as with discriminative approaches, whilst yielding well-calibrated probabilities and being robust to missing features.
Automatic Posterior Transformation for Likelihood-free Inference
A sequential neural posterior estimation method that modifies the posterior approximation using arbitrary, dynamically updated proposals. Also, it is compatible with arbitrary choices of priors, proposals, and powerful flow-based density estimators.
Jump-Start Reinforcement Learning
Reinforcement learning often presents a challenge when training an agent from scratch, as reward sparsity and exploration issues can impede learning. Leveraging offline data to warm-start the policy can significantly enhance learning, however, naive initialisation tends to yield poor results. A recent paper investigates various methods to transition from offline initialisation to online fine-tuning, providing both experimental and theoretical insights on sample complexity.
Implicit Q Learning
A core challenge when applying dynamic programming based approaches to offline reinforcement learning is the bootstrapping error. This pill presents a paper proposing an algorithm called implicit Q learning that mitigates bootstrapping issues by modifying the argmax in the Bellman equation.
