Neuro-memristive Circuits for Edge Computing: A review
The volume, veracity, variability, and velocity of data produced from the
ever-increasing network of sensors connected to Internet pose challenges for
power management, scalability, and sustainability of cloud computing
infrastructure. Increasing the data processing capability of edge computing
devices at lower power requirements can reduce several overheads for cloud
computing solutions. This paper provides the review of neuromorphic
CMOS-memristive architectures that can be integrated into edge computing
devices. We discuss why the neuromorphic architectures are useful for edge
devices and show the advantages, drawbacks and open problems in the field of
neuro-memristive circuits for edge computing
Accelerating Deterministic and Stochastic Binarized Neural Networks on FPGAs Using OpenCL
Recent technological advances have proliferated the available computing
power, memory, and speed of modern Central Processing Units (CPUs), Graphics
Processing Units (GPUs), and Field Programmable Gate Arrays (FPGAs).
Consequently, the performance and complexity of Artificial Neural Networks
(ANNs) is burgeoning. While GPU accelerated Deep Neural Networks (DNNs)
currently offer state-of-the-art performance, they consume large amounts of
power. Training such networks on CPUs is inefficient, as data throughput and
parallel computation is limited. FPGAs are considered a suitable candidate for
performance critical, low power systems, e.g. the Internet of Things (IOT) edge
devices. Using the Xilinx SDAccel or Intel FPGA SDK for OpenCL development
environment, networks described using the high-level OpenCL framework can be
accelerated on heterogeneous platforms. Moreover, the resource utilization and
power consumption of DNNs can be further enhanced by utilizing regularization
techniques that binarize network weights. In this paper, we introduce, to the
best of our knowledge, the first FPGA-accelerated stochastically binarized DNN
implementations, and compare them to implementations accelerated using both
GPUs and FPGAs. Our developed networks are trained and benchmarked using the
popular MNIST and CIFAR-10 datasets, and achieve near state-of-the-art
performance, while offering a >16-fold improvement in power consumption,
compared to conventional GPU-accelerated networks. Both our FPGA-accelerated
determinsitic and stochastic BNNs reduce inference times on MNIST and CIFAR-10
by >9.89x and >9.91x, respectively.Comment: 4 pages, 3 figures, 1 tabl
Compression-aware Training of Deep Networks
In recent years, great progress has been made in a variety of application
domains thanks to the development of increasingly deeper neural networks.
Unfortunately, the huge number of units of these networks makes them expensive
both computationally and memory-wise. To overcome this, exploiting the fact
that deep networks are over-parametrized, several compression strategies have
been proposed. These methods, however, typically start from a network that has
been trained in a standard manner, without considering such a future
compression. In this paper, we propose to explicitly account for compression in
the training process. To this end, we introduce a regularizer that encourages
the parameter matrix of each layer to have low rank during training. We show
that accounting for compression during training allows us to learn much more
compact, yet at least as effective, models than state-of-the-art compression
techniques.Comment: Accepted at NIPS 201
