Zero-shot Retrieval: Augmenting Pre-trained Models with Search Engines

no code implementations29 Nov 2023 Hamed Damirchi, Cristian Rodríguez-Opazo, Ehsan Abbasnejad, Damien Teney, Javen Qinfeng Shi, Stephen Gould, Anton Van Den Hengel

Large pre-trained models can dramatically reduce the amount of task-specific data required to solve a problem, but they often fail to capture domain-specific nuances out of the box.

Independent Modular Networks

no code implementations2 Jun 2023 Hamed Damirchi, Forest Agostinelli, Pooyan Jamshidi

However, a lack of structure in each module's role, and modular network-specific issues such as module collapse have restricted their usability.

Action Capsules: Human Skeleton Action Recognition

no code implementations30 Jan 2023 Ali Farajzadeh Bavil, Hamed Damirchi, Hamid D. Taghirad

Due to the compact and rich high-level representations offered, skeleton-based human action recognition has recently become a highly active research topic.

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.

Deep Inertial Odometry with Accurate IMU Preintegration

no code implementations18 Jan 2021 Rooholla Khorrambakht, Chris Xiaoxuan Lu, Hamed Damirchi, Zhenghua Chen, Zhengguo Li

Inertial Measurement Units (IMUs) are interceptive modalities that provide ego-motion measurements independent of the environmental factors.

Exploring Self-Attention for Visual Odometry

no code implementations17 Nov 2020 Hamed Damirchi, Rooholla Khorrambakht, Hamid D. Taghirad

Visual odometry networks commonly use pretrained optical flow networks in order to derive the ego-motion between consecutive frames.

ARC-Net: Activity Recognition Through Capsules

no code implementations6 Jul 2020 Hamed Damirchi, Rooholla Khorrambakht, Hamid Taghirad

We provide heatmaps of the priors, learned by the network, to visualize the utilization of each of the data sources by the trained network.
