D3: Data Diversity Design for Systematic Generalization in Visual Question Answering

1 code implementation15 Sep 2023 Amir Rahimi, Vanessa D'Amario, Moyuru Yamada, Kentaro Takemoto, Tomotake Sasaki, Xavier Boix

We demonstrate that this result is independent of the similarity between the training and testing data and applies to well-known families of neural network architectures for VQA (i. e. monolithic architectures and neural module networks).

Semi-Supervised 3D Hand Shape and Pose Estimation with Label Propagation

no code implementations30 Nov 2021 Samira Kaviani, Amir Rahimi, Richard Hartley

To obtain 3D annotations, we are restricted to controlled environments or synthetic datasets, leading us to 3D datasets with less generalizability to real-world scenarios.

CogSense: A Cognitively Inspired Framework for Perception Adaptation

no code implementations22 Jul 2021 Hyukseong Kwon, Amir Rahimi, Kevin G. Lee, Amit Agarwal, Rajan Bhattacharyya

This paper proposes the CogSense system, which is inspired by sense-making cognition and perception in the mammalian brain to perform perception error detection and perception parameter adaptation using probabilistic signal temporal logic.

Few-shot Weakly-Supervised Object Detection via Directional Statistics

no code implementations25 Mar 2021 Amirreza Shaban, Amir Rahimi, Thalaiyasingam Ajanthan, Byron Boots, Richard Hartley

When the novel objects are localized, we utilize them to learn a linear appearance model to detect novel classes in new images.

Calibration of Neural Networks using Splines

1 code implementation ICLR 2021 Kartik Gupta, Amir Rahimi, Thalaiyasingam Ajanthan, Thomas Mensink, Cristian Sminchisescu, Richard Hartley

From this, by approximating the empirical cumulative distribution using a differentiable function via splines, we obtain a recalibration function, which maps the network outputs to actual (calibrated) class assignment probabilities.

Post-hoc Calibration of Neural Networks by g-Layers

no code implementations23 Jun 2020 Amir Rahimi, Thomas Mensink, Kartik Gupta, Thalaiyasingam Ajanthan, Cristian Sminchisescu, Richard Hartley

Calibration of neural networks is a critical aspect to consider when incorporating machine learning models in real-world decision-making systems where the confidence of decisions are equally important as the decisions themselves.

Pairwise Similarity Knowledge Transfer for Weakly Supervised Object Localization

1 code implementation ECCV 2020 Amir Rahimi, Amirreza Shaban, Thalaiyasingam Ajanthan, Richard Hartley, Byron Boots

Weakly Supervised Object Localization (WSOL) methods only require image level labels as opposed to expensive bounding box annotations required by fully supervised algorithms.

Intra Order-preserving Functions for Calibration of Multi-Class Neural Networks

1 code implementation NeurIPS 2020 Amir Rahimi, Amirreza Shaban, Ching-An Cheng, Richard Hartley, Byron Boots

A common approach is to learn a post-hoc calibration function that transforms the output of the original network into calibrated confidence scores while maintaining the network's accuracy.

Predicting protein-protein interactions based on rotation of proteins in 3D-space

no code implementations22 Dec 2017 Samaneh Aghajanbaglo, Sobhan Moosavi, Maseud Rahgozar, Amir Rahimi

Therefore, a unique category of prediction approaches has been devised which is based on the protein sequence information.
