Visual Concept Connectome (VCC): Open World Concept Discovery and their Interlayer Connections in Deep Models

no code implementations2 Apr 2024 Matthew Kowal, Richard P. Wildes, Konstantinos G. Derpanis

Understanding what deep network models capture in their learned representations is a fundamental challenge in computer vision.

Multi-modal News Understanding with Professionally Labelled Videos (ReutersViLNews)

no code implementations23 Jan 2024 Shih-Han Chou, Matthew Kowal, Yasmin Niknam, Diana Moyano, Shayaan Mehdi, Richard Pito, Cheng Zhang, Ian Knopke, Sedef Akinli Kocak, Leonid Sigal, Yalda Mohsenzadeh

Towards a solution for designing this ability in algorithms, we present a large-scale analysis on an in-house dataset collected by the Reuters News Agency, called Reuters Video-Language News (ReutersViLNews) dataset which focuses on high-level video-language understanding with an emphasis on long-form news.

Understanding Video Transformers via Universal Concept Discovery

no code implementations19 Jan 2024 Matthew Kowal, Achal Dave, Rares Ambrus, Adrien Gaidon, Konstantinos G. Derpanis, Pavel Tokmakov

Concretely, we seek to explain the decision-making process of video transformers based on high-level, spatiotemporal concepts that are automatically discovered.

Simpler Does It: Generating Semantic Labels with Objectness Guidance

no code implementations20 Oct 2021 Md Amirul Islam, Matthew Kowal, Sen Jia, Konstantinos G. Derpanis, Neil D. B. Bruce

Extensive experiments demonstrate the high quality of our generated pseudo-labels and effectiveness of the proposed framework in a variety of domains.

SegMix: Co-occurrence Driven Mixup for Semantic Segmentation and Adversarial Robustness

no code implementations23 Aug 2021 Md Amirul Islam, Matthew Kowal, Konstantinos G. Derpanis, Neil D. B. Bruce

The premise is based on the notion of feature binding, which is defined as the process by which activations spread across space and layers in the network are successfully integrated to arrive at a correct inference decision.

Global Pooling, More than Meets the Eye: Position Information is Encoded Channel-Wise in CNNs

1 code implementation ICCV 2021 Md Amirul Islam, Matthew Kowal, Sen Jia, Konstantinos G. Derpanis, Neil D. B. Bruce

In this paper, we challenge the common assumption that collapsing the spatial dimensions of a 3D (spatial-channel) tensor in a convolutional neural network (CNN) into a vector via global pooling removes all spatial information.

Shape or Texture: Understanding Discriminative Features in CNNs

no code implementations27 Jan 2021 Md Amirul Islam, Matthew Kowal, Patrick Esser, Sen Jia, Bjorn Ommer, Konstantinos G. Derpanis, Neil Bruce

Contrasting the previous evidence that neurons in the later layers of a Convolutional Neural Network (CNN) respond to complex object shapes, recent studies have shown that CNNs actually exhibit a `texture bias': given an image with both texture and shape cues (e. g., a stylized image), a CNN is biased towards predicting the category corresponding to the texture.

Boundary Effects in CNNs: Feature or Bug?

no code implementations1 Jan 2021 Md Amirul Islam, Matthew Kowal, Sen Jia, Konstantinos G. Derpanis, Neil Bruce

Finally, we demonstrate the implications of these findings on a number of real-world tasks to show that position information can act as a feature or a bug.

Feature Binding with Category-Dependant MixUp for Semantic Segmentation and Adversarial Robustness

no code implementations13 Aug 2020 Md Amirul Islam, Matthew Kowal, Konstantinos G. Derpanis, Neil D. B. Bruce

In this paper, we present a strategy for training convolutional neural networks to effectively resolve interference arising from competing hypotheses relating to inter-categorical information throughout the network.
