Towards Sim-to-Real Industrial Parts Classification with Synthetic Dataset

1 code implementation12 Apr 2024 Xiaomeng Zhu, Talha Bilal, Pär Mårtensson, Lars Hanson, Mårten Björkman, Atsuto Maki

To this end, we introduce a synthetic dataset that may serve as a preliminary testbed for the Sim-to-Real challenge; it contains 17 objects of six industrial use cases, including isolated and assembled parts.

ZoDi: Zero-Shot Domain Adaptation with Diffusion-Based Image Transfer

no code implementations20 Mar 2024 Hiroki Azuma, Yusuke Matsui, Atsuto Maki

Deep learning models achieve high accuracy in segmentation tasks among others, yet domain shift often degrades the models' performance, which can be critical in real-world scenarios where no target images are available.

Marginal Thresholding in Noisy Image Segmentation

no code implementations8 Apr 2023 Marcus Nordström, Henrik Hult, Atsuto Maki

Based on recent work on loss function characterization, it is shown that optimal solutions to soft-Dice can be recovered by thresholding solutions to cross-entropy with a particular a priori unknown threshold that efficiently can be computed.

Noisy Image Segmentation With Soft-Dice

no code implementations3 Apr 2023 Marcus Nordström, Henrik Hult, Atsuto Maki, Fredrik Löfman

This paper presents a study on the soft-Dice loss, one of the most popular loss functions in medical image segmentation, for situations where noise is present in target labels.

Dense FixMatch: a simple semi-supervised learning method for pixel-wise prediction tasks

1 code implementation18 Oct 2022 Miquel Martí i Rabadán, Alessandro Pieropan, Hossein Azizpour, Atsuto Maki

We propose Dense FixMatch, a simple method for online semi-supervised learning of dense and structured prediction tasks combining pseudo-labeling and consistency regularization via strong data augmentation.

Towards a Unified View of Affinity-Based Knowledge Distillation

no code implementations30 Sep 2022 Vladimir Li, Atsuto Maki

In this paper, by explicitly modularising knowledge distillation into a framework of three components, i. e. affinity, normalisation, and loss, we give a unified treatment of these algorithms as well as study a number of unexplored combinations of the modules.

Discriminant analysis based on projection onto generalized difference subspace

no code implementations29 Oct 2019 Kazuhiro Fukui, Naoya Sogi, Takumi Kobayashi, Jing-Hao Xue, Atsuto Maki

To avoid the difficulty, we first introduce geometrical Fisher discriminant analysis (gFDA) based on a simplified Fisher criterion.

Target Aware Network Adaptation for Efficient Representation Learning

no code implementations2 Oct 2018 Yang Zhong, Vladimir Li, Ryuzo Okada, Atsuto Maki

This paper presents an automatic network adaptation method that finds a ConvNet structure well-suited to a given target task, e. g., image classification, for efficiency as well as accuracy in transfer learning.

A multitask deep learning model for real-time deployment in embedded systems

no code implementations31 Oct 2017 Miquel Martí, Atsuto Maki

We propose an approach to Multitask Learning (MTL) to make deep learning models faster and lighter for applications in which multiple tasks need to be solved simultaneously, which is particularly useful in embedded, real-time systems.

A systematic study of the class imbalance problem in convolutional neural networks

3 code implementations15 Oct 2017 Mateusz Buda, Atsuto Maki, Maciej A. Mazurowski

In our study, we use three benchmark datasets of increasing complexity, MNIST, CIFAR-10 and ImageNet, to investigate the effects of imbalance on classification and perform an extensive comparison of several methods to address the issue: oversampling, undersampling, two-phase training, and thresholding that compensates for prior class probabilities.

Persistent Evidence of Local Image Properties in Generic ConvNets

no code implementations24 Nov 2014 Ali Sharif Razavian, Hossein Azizpour, Atsuto Maki, Josephine Sullivan, Carl Henrik Ek, Stefan Carlsson

Supervised training of a convolutional network for object classification should make explicit any information related to the class of objects and disregard any auxiliary information associated with the capture of the image or the variation within the object class.

Factors of Transferability for a Generic ConvNet Representation

no code implementations22 Jun 2014 Hossein Azizpour, Ali Sharif Razavian, Josephine Sullivan, Atsuto Maki, Stefan Carlsson

In the common scenario, a ConvNet is trained on a large labeled dataset (source) and the feed-forward units activation of the trained network, at a certain layer of the network, is used as a generic representation of an input image for a task with relatively smaller training set (target).
