Enhancing Visual Perception in Novel Environments via Incremental Data Augmentation Based on Style Transfer

1 code implementation16 Sep 2023 Abhibha Gupta, Rully Agus Hendrawan, Mansur Arief

The deployment of autonomous agents in real-world scenarios is challenged by "unknown unknowns", i. e. novel unexpected environments not encountered during training, such as degraded signs.

Designing an Optimized Electric Vehicle Charging Station Infrastructure for Urban Area: A Case study from Indonesia

no code implementations7 Sep 2022 Nissa Amilia, Zulkifli Palinrungi, Iwan Vanany, Mansur Arief

The rapid development of electric vehicle (EV) technologies promises cleaner air and more efficient transportation systems, especially for polluted and congested urban areas.

Test Against High-Dimensional Uncertainties: Accelerated Evaluation of Autonomous Vehicles with Deep Importance Sampling

no code implementations4 Apr 2022 Mansur Arief, Zhepeng Cen, Zhenyuan Liu, Zhiyuang Huang, Henry Lam, Bo Li, Ding Zhao

In this work, we present Deep Importance Sampling (Deep IS) framework that utilizes a deep neural network to obtain an efficient IS that is on par with the state-of-the-art, capable of reducing the required sample size 43 times smaller than the naive sampling method to achieve 10% relative error and while producing an estimate that is much less conservative.
