Online Probabilistic Model Identification using Adaptive Recursive MCMC

1 code implementation23 Oct 2022 Pedram Agand, Mo Chen, Hamid D. Taghirad

We suggest the Adaptive Recursive Markov Chain Monte Carlo (ARMCMC) method, which eliminates the shortcomings of conventional online techniques while computing the entire probability density function of model parameters.

A Segment-Wise Gaussian Process-Based Ground Segmentation With Local Smoothness Estimation

A Consistency-Based Loss for Deep Odometry Through Uncertainty Propagation

no code implementations1 Jul 2021 Hamed Damirchi, Rooholla Khorrambakht, Hamid D. Taghirad, Behzad Moshiri

In such cases where multiple losses are imposed on a network, the uncertainty over each output can be derived to weigh the different loss terms in a maximum likelihood setting.

Bounded Inputs Total Energy Shaping for Mechanical Systems

no code implementations6 Apr 2021 M. Reza J. Harandi, Amir Molaei, Hamid D. Taghirad, Jose Guadalupe Romero

However, actuator saturation is typically neglected in the design of control systems, with compensation being made in the form of over-designing the actuator or by post-analyzing the resulting system to ensure acceptable performance.

Single Object Tracking through a Fast and Effective Single-Multiple Model Convolutional Neural Network

no code implementations28 Mar 2021 Faraz Lotfi, Hamid D. Taghirad

Recent state-of-the-art (SOTA) approaches are proposed based on taking a matching network with a heavy structure to distinguish the target from other objects in the area which indeed drastically downgrades the performance of the tracker in terms of speed.
