Multimodal Representations for Teacher-Guided Compositional Visual Reasoning

no code implementations24 Oct 2023 Wafa Aissa, Marin Ferecatu, Michel Crucianu

Neural Module Networks (NMN) are a compelling method for visual question answering, enabling the translation of a question into a program consisting of a series of reasoning sub-tasks that are sequentially executed on the image to produce an answer.

Curriculum Learning for Compositional Visual Reasoning

no code implementations27 Mar 2023 Wafa Aissa, Marin Ferecatu, Michel Crucianu

Visual Question Answering (VQA) is a complex task requiring large datasets and expensive training.

Why is the prediction wrong? Towards underfitting case explanation via meta-classification

no code implementations20 Feb 2023 Sheng Zhou, Pierre Blanchart, Michel Crucianu, Marin Ferecatu

In this paper we present a heuristic method to provide individual explanations for those elements in a dataset (data points) which are wrongly predicted by a given classifier.

Efficient Autoprecoder-based deep learning for massive MU-MIMO Downlink under PA Non-Linearities

no code implementations3 Feb 2022 Xinying Cheng, Rafik Zayani, Marin Ferecatu, Nicolas Audebert

Specifically, we aim to design the PA-aware precoder and the receive decoder by leveraging the concept of autoprecoder, whereas the end-to-end massive multiuser (MU)-MIMO downlink is designed using a deep neural network (NN).

Global Vertices and the Noising Paradox

no code implementations2 Aug 2016 Konstantinos A. Raftopoulos, Stefanos D. Kollias, Marin Ferecatu

A theoretical and experimental analysis related to the identification of vertices of unknown shapes is presented.

Incremental Noising and its Fractal Behavior

no code implementations28 Jul 2016 Konstantinos A. Raftopoulos, Marin Ferecatu, Dionyssios D. Sourlas, Stefanos D. Kollias

This manuscript is about investigating this claim by introducing incremental noising, in a recursive deterministic manner, analogous to how smoothing is extended to progressive smoothing in similar tasks.

Noising versus Smoothing for Vertex Identification in Unknown Shapes

no code implementations CVPR 2014 Konstantinos A. Raftopoulos, Marin Ferecatu

A method for identifying shape features of local nature on the shape's boundary, in a way that is facilitated by the presence of noise is presented.
