Spectrum Occupancy Detection Supported by Federated Learning
Dynamic spectrum access is essential for radiocommunication and its limited spectrum resources. The key element of dynamic spectrum access systems is effective spectrum occupancy detection. In many cases, machine learning algorithms improve detection effectiveness. Because of the recent trend of using federated learning, a federated learning algorithm is presented in the context of distributed spectrum occupancy detection. The results of the work presented in the paper are based on actual signa…

Preventing Reward Hacking with Occupancy Measure Regularization
Reward hacking occurs when an agent performs very well with respect to a "proxy" reward function (which may be hand-specified or learned), but poorly with respect to the unknown true reward. Since ensuring good alignment between the proxy and true reward is extremely difficult, one approach to prevent reward hacking is optimizing the proxy conservatively. Prior work has particularly focused on enforcing the learned policy to behave similarly to a "safe" policy by penalizing the KL divergence be…

Couldn't find this when I really needed it for a presentation, so here's that one bugs bunny cyber espionage meme occupying my brain all the time, author unknown (to me)

Procurar coisas sobre Foucault no Youtube é sempre algo meio estranho. Valeria lembrar que nos anos 1980, quando começavam a se multiplicar as câmeras de vigilância, sempre havia alguém pronto a falar sobre o argumento do panopticismo e da sociedade de vigilância generalizada, sob os argumentos de Vigiar e Punir.
Hoje hš quem abra canal do Youtube para falar sobre Foucault e divulgar sua "obra". Mas hš também quem não abra canais e apareça por ali a convite ou sob algum registro de evento. Cada um ocupando um pequenino papel em políticas de segmentação e publicidade.

Unified Spatio-Temporal Tri-Perspective View Representation for 3D Semantic Occupancy Prediction
Holistic understanding and reasoning in 3D scenes play a vital role in the success of autonomous driving systems. The evolution of 3D semantic occupancy prediction as a pretraining task for autonomous driving and robotic downstream tasks capture finer 3D details compared to methods like 3D detection. Existing approaches predominantly focus on spatial cues such as tri-perspective view embeddings (TPV), often overlooking temporal cues. This study introduces a spatiotemporal transformer architectu…

Accurate Pose Prediction on Signed Distance Fields for Mobile Ground Robots in Rough Terrain
Autonomous locomotion for mobile ground robots in unstructured environments such as waypoint navigation or flipper control requires a sufficiently accurate prediction of the robot-terrain interaction. Heuristics like occupancy grids or traversability maps are widely used but limit actions available to robots with active flippers as joint positions are not taken into account. We present a novel iterative geometric method to predict the 3D pose of mobile ground robots with active flippers on unev…
