Improving Gradient Estimation in Evolutionary Strategies With Past Descent Directions

no code implementations11 Oct 2019 Florian Meier, Asier Mujika, Marcelo Matheus Gauy, Angelika Steger

Finally, we evaluate our approach empirically on MNIST and reinforcement learning tasks and show that it considerably improves the gradient estimation of ES at no extra computational cost.

The linear hidden subset problem for the (1+1) EA with scheduled and adaptive mutation rates

no code implementations16 Aug 2018 Hafsteinn Einarsson, Marcelo Matheus Gauy, Johannes Lengler, Florian Meier, Asier Mujika, Angelika Steger, Felix Weissenberger

For the first setup, we give a schedule that achieves a runtime of $(1\pm o(1))\beta n \ln n$, where $\beta \approx 3. 552$, which is an asymptotic improvement over the runtime of the static setup.

Approximating Real-Time Recurrent Learning with Random Kronecker Factors

no code implementations NeurIPS 2018 Asier Mujika, Florian Meier, Angelika Steger

Despite all the impressive advances of recurrent neural networks, sequential data is still in need of better modelling.

Fast-Slow Recurrent Neural Networks

1 code implementation NeurIPS 2017 Asier Mujika, Florian Meier, Angelika Steger

Processing sequential data of variable length is a major challenge in a wide range of applications, such as speech recognition, language modeling, generative image modeling and machine translation.

Analytical Model for IEEE 802.15.4 Multi-Hop Networks with Improved Handling of Acknowledgements and Retransmissions

1 code implementation29 Jan 2015 Florian Meier, Volker Turau

The unslotted CSMA/CA MAC layer of IEEE 802. 15. 4 is closely modeled as well as an enhanced model of the neighborhood allows for consideration of collisions of packets including interferences with acknowledgements.
