Modern Convolutional Neural Network techniques for image segmentationGioele Ciaparrone
Recently, Convolutional Neural Networks have been successfully applied to image segmentation tasks. Here we present some of the most recent techniques that increased the accuracy in such tasks. First we describe the Inception architecture and its evolution, which allowed to increase width and depth of the network without increasing the computational burden. We then show how to adapt classification networks into fully convolutional networks, able to perform pixel-wise classification for segmentation tasks. We finally introduce the hypercolumn technique to further improve state-of-the-art on various fine-grained localization tasks.
Summary:
There are three parts in this presentation.
A. Why do we need Convolutional Neural Network
- Problems we face today
- Solutions for problems
B. LeNet Overview
- The origin of LeNet
- The result after using LeNet model
C. LeNet Techniques
- LeNet structure
- Function of every layer
In the following Github Link, there is a repository that I rebuilt LeNet without any deep learning package. Hope this can make you more understand the basic of Convolutional Neural Network.

A Framework for Scene Recognition Using Convolutional Neural Network as Featu...Tahmid Abtahi
Scene recognition is one of the hallmark tasks of computer vision, allowing definition of a context for object recognition. Availability of large data sets like ImageNet and VGG has provided scopes of applying machine learning classifiers to train models. However high data dimensionality is an issue while training classifiers such as Support Vector Machine (SVM) and perceptron. To reduce data dimensionality and take advantage of parallel and distributed processing, we propose a framework with Convolutional Neural Network (CNN) as Feature extractor and SVM and perceptron as the classifier. MPI (Message passing interface) was used for programming clusters of CPUs. SVM showed 1.05x times improvement over perceptron in terms of run time and CNN reduced data dimensionality by 10x times.
HardNet: Convolutional Network for Local Image DescriptionDmytro Mishkin
We introduce a novel loss for learning local feature descriptors which is inspired by the Lowe's matching criterion for SIFT. We show that the proposed loss that maximizes the distance between the closest positive and closest negative patch in the batch is better than complex regularization methods; it works well for both shallow and deep convolution network architectures. Applying the novel loss to the L2Net CNN architecture results in a compact descriptor -- it has the same dimensionality as SIFT (128) that shows state-of-art performance in wide baseline stereo, patch verification and instance retrieval benchmarks. It is fast, computing a descriptor takes about 1 millisecond on a low-end GPU.
The presentation is coverong the convolution neural network (CNN) design.
First,
the main building blocks of CNNs will be introduced. Then we systematically
investigate the impact of a range of recent advances in CNN architectures and
learning methods on the object categorization (ILSVRC) problem. In the
evaluation, the influence of the following choices of the architecture are
tested: non-linearity (ReLU, ELU, maxout, compatibility with batch
normalization), pooling variants (stochastic, max, average, mixed), network
width, classifier design (convolution, fully-connected, SPP), image
pre-processing, and of learning parameters: learning rate, batch size,
cleanliness of the data, etc.

Bio-inspired Algorithms for Evolving the Architecture of Convolutional Neural...Ashray Bhandare
In this thesis, three bio-inspired algorithms viz. genetic algorithm, particle swarm optimizer (PSO) and grey wolf optimizer (GWO) are used to optimally determine the architecture of a convolutional neural network (CNN) that is used to classify handwritten numbers. The CNN is a class of deep feed-forward network, which have seen major success in the field of visual image analysis. During training, a good CNN architecture is capable of extracting complex features from the given training data; however, at present, there is no standard way to determine the architecture of a CNN. Domain knowledge and human expertise are required in order to design a CNN architecture. Typically architectures are created by experimenting and modifying a few existing networks.
The bio-inspired algorithms determine the exact architecture of a CNN by evolving the various hyperparameters of the architecture for a given application. The proposed method was tested on the MNIST dataset, which is a large database of handwritten digits that is commonly used in many machine-learning models. The experiment was carried out on an Amazon Web Services (AWS) GPU instance, which helped to speed up the experiment time. The performance of all three algorithms was comparatively studied. The results show that the bio-inspired algorithms are capable of generating successful CNN architectures. The proposed method performs the entire process of architecture generation without any human intervention.
A comprehensive tutorial on Convolutional Neural Networks (CNN) which talks about the motivation behind CNNs and Deep Learning in general, followed by a description of the various components involved in a typical CNN layer. It explains the theory involved with the different variants used in practice and also, gives a big picture of the whole network by putting everything together.
Next, there's a discussion of the various state-of-the-art frameworks being used to implement CNNs to tackle real-world classification and regression problems.
Finally, the implementation of the CNNs is demonstrated by implementing the paper 'Age ang Gender Classification Using Convolutional Neural Networks' by Hassner (2015).

Deep learning technologies are at the core of the current revolution in artificial intelligence for multimedia data analysis. The convergence of large-scale annotated datasets and affordable GPU hardware has allowed the training of neural networks for data analysis tasks which were previously addressed with hand-crafted features. Architectures such as convolutional neural networks, recurrent neural networks and Q-nets for reinforcement learning have shaped a brand new scenario in signal processing. This course will cover the basic principles and applications of deep learning to computer vision problems, such as image classification, object detection or image captioning.

Understanding Deep Learning for Big Data: The complexity and scale of big data impose tremendous challenges for their analysis. Yet, big data also offer us great opportunities. Some nonlinear phenomena, features or relations, which are not clear or cannot be inferred reliably from small and medium data, now become clear and can be learned robustly from big data. Typically, the form of the nonlinearity is unknown to us, and needs to be learned from data as well. Being able to harness the nonlinear structures from big data could allow us to tackle problems which are impossible before or obtain results which are far better than previous state-of-the-arts.
Nowadays, deep neural networks are the methods of choice when it comes to large scale nonlinear learning problems. What makes deep neural networks work? Is there any general principle for tackling high dimensional nonlinear problems which we can learn from deep neural works? Can we design competitive or better alternatives based on such knowledge? To make progress in these questions, my machine learning group performed both theoretical and experimental analysis on existing and new deep learning architectures, and investigate three crucial aspects on the usefulness of the fully connected layers, the advantage of the feature learning process, and the importance of the compositional structures. Our results point to some promising directions for future research, and provide guideline for building new deep learning models.
Uniformity in mechanical properties of the slab affects quality of subsequent rolling process. One of the most important factors deciding quality of the slab is fluctuation of the molten steel level in the mould. That is, smoothing pouring without fluctuating in the mould level means improvement in quality of the slab and protects break-out problem and allows high speed casting process. If molten steel surface fluctuates severely, the forming oscillation marks on the slab is unstable, solidification of molten steel is not uniform and there will be entrapment of mould powder in the solidified cast strand. It makes quality of the slab inferior and generates defects on the slab.
This presentation was given to the system adminstration team to give them an idea of how GC works and what to look for when there is abottleneck and troubles.
