The document summarizes the development of a Convolutional Neural Network (CNN) library in Python. It discusses improvements made over a previous fully connected network implementation, including redesigning the data structure to support CNNs and implementing a CNN that achieved a classification accuracy of 98% on the MNIST dataset, compared to 97% for the fully connected network. It then provides details on the design of CNNs, including their convolutional and pooling layers, and describes changes made to the interface and architecture of the library to support CNNs through layered classes that connect input to output while automatically calculating dimensions.
The document describes the development and testing of a novel mathematical computing architecture called MaPU. Key highlights include a multi-granularity parallel storage system that enables simultaneous matrix row and column access, a high dimension data model, and a cascading pipeline with a state machine-based program model. The first MaPU chip was implemented on a 40nm process with 4 MaPU cores. Testing showed the MaPU core was up to 6.94 times faster than a similar TI C66x DSP core for various algorithms like FFT and matrix multiplication. Power analysis indicated tested power was within 8% of estimated power.

John Feland, CEO and Founder of Argus Insights, presents the "Overcoming Barriers to Consumer Adoption of Vision-enabled Products and Services" tutorial at the May 2015 Embedded Vision Summit.
Visual intelligence is being deployed in a growing range of consumer products, including smartphones, tablets, security cameras, laptops (especially with Intel’s RealSense push), and even smartwatches. The demos are always cool. But does vision work for regular consumers? Do consumers see vision as a value add or just another feature to be ignored?
In this talk, John investigates the best and worst of consumer product embedded vision implementations as told by real consumers, based on Argus Insights’ extensive portfolio of consumer data. John examines where current products fall short of consumers’ needs. And, he illuminates successful implementations to show how their vision capabilities create value in the lives of consumers. Case studies will include examples from Dropcam, Intel RealSense, HTC’s M8, and vision-enabled drones such as the DJI Phantom 2 Vision+.
This document provides an overview of clustering and classification techniques. It defines clustering as organizing objects into groups of similar objects and discusses common clustering algorithms like k-means and hierarchical clustering. It also provides examples of how k-means works and references for further information.
This document summarizes a research paper that presents an approach to deblurring noisy or blurred images using a kernel estimation algorithm. It begins by noting the challenges of capturing satisfactory photos in low light conditions using a hand-held camera, as images are often blurred or noisy. The proposed approach uses two degraded images - a blurred image taken with a slow shutter speed and low ISO, and a noisy image taken with a fast shutter speed and high ISO. It estimates an accurate blur kernel by exploiting structures in the noisy image, allowing it to handle larger kernels than single-image approaches. It then performs a residual deconvolution to greatly reduce ringing artifacts commonly resulting from image deconvolution. Additional steps further suppress artifacts, resulting in a final image that
1. The document summarizes several papers on deep learning and convolutional neural networks. It discusses techniques like pruning weights, trained quantization, Huffman coding, and designing networks with fewer parameters like SqueezeNet.
2. One paper proposes techniques to compress deep neural networks by pruning, trained quantization, and Huffman coding to reduce model size. It evaluates these techniques on networks for MNIST and ImageNet, achieving compression rates of 35x to 49x with no loss of accuracy.
3. Another paper introduces SqueezeNet, a CNN architecture with AlexNet-level accuracy but 50x fewer parameters and a model size of less than 0.5MB. It employs fire modules with 1x1 convolutions to
This document describes the CIFAR-10 dataset for classifying images into 10 categories. It contains 60,000 32x32 color images split into 50,000 training and 10,000 test images. Two methods are proposed: Method 1 extracts patches and features from each image and uses SVM/kNN, while Method 2 uses LoG and HoG features to preserve shape before SVM/kNN classification. Experiments test different parameters, with the best accuracy around 42% using a 13-dimensional Fisher vector and RBF SVM kernel.
(DL Hacks輪読) How transferable are features in deep neural networks?Masahiro Suzuki
This document summarizes an experiment on measuring how transferable features are in deep neural networks. The experiment trained neural networks on halves of the ImageNet dataset and tested how well the networks could generalize to the other half. It found that earlier layer features transferred better than later layer features, and that fine-tuning improved performance. Transferring between more dissimilar datasets led to poorer performance. Randomly initialized weights performed worse than trained weights.
Unsupervised Classification of Images: A ReviewCSCJournals
Unsupervised image classification is the process by which each image in a dataset is identified to be a member of one of the inherent categories present in the image collection without the use of labelled training samples. Unsupervised categorisation of images relies on unsupervised machine learning algorithms for its implementation. This paper identifies clustering algorithms and dimension reduction algorithms as the two main classes of unsupervised machine learning algorithms needed in unsupervised image categorisation, and then reviews how these algorithms are used in some notable implementation of unsupervised image classification algorithms.
This document provides an overview of image deblurring techniques. It discusses how digital images can be represented as matrices, with each pixel corresponding to an entry in the matrix. A linear model is presented for how a sharp, ideal image (X) becomes blurred (B) through a blurring matrix (A) such that Ax=b. Point spread functions are introduced to describe how a point source becomes blurred and these are used to construct the columns of the blurring matrix A. The document concludes with a simple example of applying these concepts to a small test image.
