Max Entropy Moment Kalman Filter for Polynomial Systems with Arbitrary Noise
Designing optimal Bayes filters for nonlinear non-Gaussian systems is a challenging task. The main difficulties are: 1) representing complex beliefs, 2) handling non-Gaussian noise, and 3) marginalizing past states. To address these challenges, we focus on polynomial systems and propose the Max Entropy Moment Kalman Filter (MEM-KF). To address 1), we represent arbitrary beliefs by a Moment-Constrained Max-Entropy Distribution (MED). The MED can asymptotically approximate almost any distribution…

Stochastic Neural Control Barrier Functions
Control Barrier Functions (CBFs) are utilized to ensure the safety of control systems. CBFs act as safety filters in order to provide safety guarantees without compromising system performance. These safety guarantees rely on the construction of valid CBFs. Due to their complexity, CBFs can be represented by neural networks, known as neural CBFs (NCBFs). Existing works on the verification of the NCBF focus on the synthesis and verification of NCBFs in deterministic settings, leaving the stochast…

Ilford FP4 E.I. 64 **English:** This black-and-white photograph captures a scene at a bus stop. Several people are waiting, some standing and some sitting. A woman in the foreground is engrossed in her smartphone, wearing a mask and carrying a bag. The bus stop shelter is visible, and the street outside is lined with trees and buildings, indicating an urban setting. The overall atmosphere suggests a typical day in a city with people going about their daily routines. **Chinese:** 这张黑白照片捕捉了一个公交…
Ilford FP4 E.I. 64 **English:** This black-and-white image shows the interior of a bus. The focus is on the backs of two passengers seated near the front. The bus is in motion, as suggested by the blurred scenery visible through the windows. The interior lighting is bright, illuminating the passengers and the details of the bus seats and handrails. The image conveys a sense of movement and daily commuting. **Chinese:** 这张黑白图片展示了公交车内部的场景。焦点集中在靠近前部的两名乘客的背影上。公交车正在行驶中，从窗外模糊的景色可以看出这一点。车内的灯光明亮，照亮了乘…
Ilford FP4 E.I. 64 **English:** This black-and-white photograph depicts a tranquil scene in what appears to be a park or a tree-lined street. A person is riding a bicycle away from the camera down a paved path, surrounded by lush trees and greenery. The sunlight filters through the leaves, casting dappled shadows on the ground. The image evokes a sense of peace and leisurely activity in a natural setting. **Chinese:** 这张黑白照片描绘了一个看似公园或绿树成荫的街道上的宁静场景。一个人正骑着自行车远离相机，沿着铺好的小路骑行，周围环绕着茂密的树木和绿地。阳光透过树叶，…
Ilford FP4 E.I. 64 **English:** This black-and-white image captures a moment at a bus station. In the foreground, a woman wearing a cap is seen from the side, possibly talking or looking at something off-camera. Behind him, a large bus is parked, with visible text on its side. The bus station appears busy, with other people and vehicles in the background. The scene suggests a bustling transportation hub with people in transit. **Chinese:** 这张黑白图片捕捉了公交车站的一个瞬间。前景中，一个戴帽子的女人从侧面可见，可能正在说话或看着镜头外的某物。…
