Comparative Study of Caffe, Neon, Theano, and Torch
Workshop track - ICLR 2016 COMPARATIVE STUDY OF CAFFE,NEON,THEANO, AND TORCH FOR DEEP LEARNING Soheil Bahrampour, Naveen Ramakrishnan, Lukas Schott, Mohak Shah Bosch Research and Technology Center fSoheil.Bahrampour,Naveen.Ramakrishnan, fixed-term.Lukas.Schott,[email protected] ABSTRACT Deep learning methods have resulted in significant performance improvements in several application domains and as such several software frameworks have been developed to facilitate their implementation. This paper presents a comparative study of four deep learning frameworks, namely Caffe, Neon, Theano, and Torch, on three aspects: extensibility, hardware utilization, and speed. The study is per- formed on several types of deep learning architectures and we evaluate the per- formance of the above frameworks when employed on a single machine for both (multi-threaded) CPU and GPU (Nvidia Titan X) settings. The speed performance metrics used here include the gradient computation time, which is important dur- ing the training phase of deep networks, and the forward time, which is important from the deployment perspective of trained networks. For convolutional networks, we also report how each of these frameworks support various convolutional algo- rithms and their corresponding performance. From our experiments, we observe that Theano and Torch are the most easily extensible frameworks. We observe that Torch is best suited for any deep architecture on CPU, followed by Theano. It also achieves the best performance on the GPU for large convolutional and fully connected networks, followed closely by Neon. Theano achieves the best perfor- mance on GPU for training and deployment of LSTM networks. Finally Caffe is the easiest for evaluating the performance of standard deep architectures. -
Torch7: a Matlab-Like Environment for Machine Learning
Torch7: A Matlab-like Environment for Machine Learning Ronan Collobert1 Koray Kavukcuoglu2 Clement´ Farabet3;4 1 Idiap Research Institute 2 NEC Laboratories America Martigny, Switzerland Princeton, NJ, USA 3 Courant Institute of Mathematical Sciences 4 Universite´ Paris-Est New York University, New York, NY, USA Equipe´ A3SI - ESIEE Paris, France Abstract Torch7 is a versatile numeric computing framework and machine learning library that extends Lua. Its goal is to provide a flexible environment to design and train learning machines. Flexibility is obtained via Lua, an extremely lightweight scripting language. High performance is obtained via efficient OpenMP/SSE and CUDA implementations of low-level numeric routines. Torch7 can easily be in- terfaced to third-party software thanks to Lua’s light interface. 1 Torch7 Overview With Torch7, we aim at providing a framework with three main advantages: (1) it should ease the development of numerical algorithms, (2) it should be easily extended (including the use of other libraries), and (3) it should be fast. We found that a scripting (interpreted) language with a good C API appears as a convenient solu- tion to “satisfy” the constraint (2). First, a high-level language makes the process of developing a program simpler and more understandable than a low-level language. Second, if the programming language is interpreted, it becomes also easier to quickly try various ideas in an interactive manner. And finally, assuming a good C API, the scripting language becomes the “glue” between hetero- geneous libraries: different structures of the same concept (coming from different libraries) can be hidden behind a unique structure in the scripting language, while keeping all the functionalities coming from all the different libraries. -

Introduction to Deep Learning Framework 1. Introduction 1.1
Introduction to Deep Learning Framework 1. Introduction 1.1. Commonly used frameworks The most commonly used frameworks for deep learning include Pytorch, Tensorflow, Keras, caffe, Apache MXnet, etc. PyTorch: open source machine learning library; developed by Facebook AI Rsearch Lab; based on the Torch library; supports Python and C++ interfaces. Tensorflow: open source software library dataflow and differentiable programming; developed by Google brain team; provides stable Python & C APIs. Keras: an open-source neural-network library written in Python; conceived to be an interface; capable of running on top of TensorFlow, Microsoft Cognitive Toolkit, R, Theano, or PlaidML. Caffe: open source under BSD licence; developed at University of California, Berkeley; written in C++ with a Python interface. Apache MXnet: an open-source deep learning software framework; supports a flexible programming model and multiple programming languages (including C++, Python, Java, Julia, Matlab, JavaScript, Go, R, Scala, Perl, and Wolfram Language.) 1.2. Pytorch 1.2.1 Data Tensor: the major computation unit in PyTorch. Tensor could be viewed as the extension of vector (one-dimensional) and matrix (two-dimensional), which could be defined with any dimension. Variable: a wrapper of tensor, which includes creator, value of variable (tensor), and gradient. This is the core of the automatic derivation in Pytorch, as it has the information of both the value and the creator, which is very important for current backward process. Parameter: a subset of variable 1.2.2. Functions: NNModules: NNModules (torch.nn) is a combination of parameters and functions, and could be interpreted as layers. There some common modules such as convolution layers, linear layers, pooling layers, dropout layers, etc. -

DLL: a Fast Deep Neural Network Library
Published in Artificial Neural Networks in Pattern Recognition. ANNPR 2018, Lecture Notes in Computer Science, vol. 11081, which should be cited to refer to this work. DOI: https://doi.org/10.1007/978-3-319-99978-4_4 DLL: A Fast Deep Neural Network Library Baptiste Wicht, Andreas Fischer, and Jean Hennebert 1 HES-SO, University of Applied Science of Western Switzerland 2 University of Fribourg, Switzerland Abstract. Deep Learning Library (DLL) is a library for machine learn- ing with deep neural networks that focuses on speed. It supports feed- forward neural networks such as fully-connected Artificial Neural Net- works (ANNs) and Convolutional Neural Networks (CNNs). Our main motivation for this work was to propose and evaluate novel software engineering strategies with potential to accelerate runtime for training and inference. Such strategies are mostly independent of the underlying deep learning algorithms. On three different datasets and for four dif- ferent neural network models, we compared DLL to five popular deep learning libraries. Experimentally, it is shown that the proposed library is systematically and significantly faster on CPU and GPU. In terms of classification performance, similar accuracies as the other libraries are reported. 1 Introduction In recent years, neural networks have regained a large deal of attention with deep learning approaches. Such approaches rely on the use of bigger and deeper networks, typically by using larger input dimensions to incorporate more con- text and by increasing the number of layers to extract information at different levels of granularity. The success of deep learning can be attributed mainly to three factors. First, there is the advent of big data, meaning the availability of larger quantities of training data. -
