The Trifecta: Three simple techniques for training deeper Forward-Forward networks

1 code implementation29 Nov 2023 Thomas Dooms, Ing Jyh Tsang, Jose Oramas

Local learning, which focuses on updating subsets of a model's parameters at a time, has emerged as a promising technique to address these issues.

Considering Layerwise Importance in the Lottery Ticket Hypothesis

no code implementations22 Feb 2023 Benjamin Vandersmissen, Jose Oramas

The Lottery Ticket Hypothesis (LTH) showed that by iteratively training a model, removing connections with the lowest global weight magnitude and rewinding the remaining connections, sparse networks can be extracted.

On The Coherence of Quantitative Evaluation of Visual Explanations

1 code implementation14 Feb 2023 Benjamin Vandersmissen, Jose Oramas

We complement our study with sanity checks on the studied evaluation methods as a means to investigate their reliability and the impact of characteristics of the explanations on the evaluation methods.

Towards Human-Understandable Visual Explanations: Human Imperceptible Cues Can Better Be Removed

no code implementations29 Sep 2021 Kaili Wang, Jose Oramas, Tinne Tuytelaars

Explainable AI (XAI) methods focus on explaining what a neural network has learned - in other words, identifying the features that are the most influential to the prediction.

Playing Atari with Capsule Networks: A systematic comparison of CNN and CapsNets-based agents.

no code implementations1 Jan 2021 Akash Singh, Kevin Mets, Jose Oramas, Steven Latré

In this paper, we conduct a systematic analysis to explore the potential of CapsNets-based agents in the deep reinforcement learning setting.

Multiple Exemplars-based Hallucinationfor Face Super-resolution and Editing

no code implementations16 Sep 2020 Kaili Wang, Jose Oramas, Tinne Tuytelaars

Given a really low-resolution input image of a face (say 16x16 or 8x8 pixels), the goal of this paper is to reconstruct a high-resolution version thereof.

Information Compensation for Deep Conditional Generative Networks

no code implementations23 Jan 2020 Zehao Wang, Kaili Wang, Tinne Tuytelaars, Jose Oramas

In recent years, unsupervised/weakly-supervised conditional generative adversarial networks (GANs) have achieved many successes on the task of modeling and generating data.

Visual Explanation by Interpretation: Improving Visual Feedback Capabilities of Deep Neural Networks

no code implementations ICLR 2019 Jose Oramas, Kaili Wang, Tinne Tuytelaars

In this paper, we propose a novel scheme for both interpretation as well as explanation in which, given a pretrained model, we automatically identify internal features relevant for the set of classes considered by the model, without relying on additional annotations.

An Analysis of Human-centered Geolocation

2 code implementations10 Jul 2017 Kaili Wang, Yu-Hui Huang, Jose Oramas, Luc van Gool, Tinne Tuytelaars

Experiments on the Fashion 144k and a Pinterest-based dataset show that the automatic methods succeed at this task to a reasonable extent.

Context-based Object Viewpoint Estimation: A 2D Relational Approach

no code implementations21 Apr 2017 Jose Oramas, Luc De Raedt, Tinne Tuytelaars

To estimate the viewpoint (or pose) of an object, people have mostly looked at object intrinsic features, such as shape or appearance.

Modeling Visual Compatibility through Hierarchical Mid-level Elements

no code implementations31 Mar 2016 Jose Oramas, Tinne Tuytelaars

At the base-level, our method identifies patterns of CNN activations with the aim of modeling different variations/styles in which objects of the classes of interest may occur.

Rank Pooling for Action Recognition

1 code implementation6 Dec 2015 Basura Fernando, Efstratios Gavves, Jose Oramas, Amir Ghodrati, Tinne Tuytelaars

We show how the parameters of a function that has been fit to the video data can serve as a robust new video representation.
