Adaptive Rational Activations to Boost Deep Reinforcement Learning

ICLR 2024spotlight

Latest insights from biology show that intelligence not only emerges from the connections between neurons, but that individual neurons shoulder more computational responsibility than previously anticipated. Specifically, neural plasticity should be critical in the context of constantly changing rein…

Einsum Networks: Fast and Scalable Learning of Tractable Probabilistic Circuits

ICML 2020poster

Probabilistic circuits (PCs) are a promising avenue for probabilistic modeling, as they permit a wide range of exact and efficient inference routines. Recent “deep-learning-style” implementations of PCs strive for a better scalability, but are still difficult to train on real-world data, due to thei…

Padé Activation Units: End-to-end Learning of Flexible Activation Functions in Deep Networks

ICLR 2020poster

The performance of deep network learning strongly depends on the choice of the non-linear activation function associated with each neuron. However, deciding on the best activation is non-trivial and the choice depends on the architecture, hyper-parameters, and even on the dataset. Typically these ac…

Random Sum-Product Networks: A Simple and Effective Approach to Probabilistic Deep Learning

UAI 2019poster

Sum-product networks (SPNs) are expressive probabilistic models with a rich set of exact and efficient inference routines. However, in order to guarantee exact inference, they require specific structural constraints, which complicate learning SPNs from data. Thereby, most SPN structure learners prop…
