What deep learning really means

#artificialintelligence

Natural language processing (NLP) is another major application area for deep learning. In addition to the machine translation problem addressed by Google Translate, major NLP tasks include automatic summarization, co-reference resolution, discourse analysis, morphological segmentation, named entity recognition, natural language generation, natural language understanding, part-of-speech tagging, sentiment analysis, and speech recognition. In addition to CNNs, NLP tasks are often addressed with recurrent neural networks (RNNs), which include the Long Short Term Memory (LSTM) model. While the biggest cloud GPU instances can cost $14 per hour to run, there are less expensive alternatives.


PyTorch or TensorFlow?

@machinelearnbot

PyTorch is essentially a GPU enabled drop-in replacement for NumPy equipped with higher-level functionality for building and training deep neural networks. In PyTorch the graph construction is dynamic, meaning the graph is built at run-time. TensorFlow does have thedynamic_rnn for the more common constructs but creating custom dynamic computations is more difficult. I haven't found the tools for data loading in TensorFlow (readers, queues, queue runners, etc.)


Where Major Chip Companies Are Investing In AI, AR/VR, And IoT

#artificialintelligence

We dug into the private market bets made by major computer chip companies, including GPU makers. Our analysis encompasses the venture arms of NVIDIA, Intel, Samsung, AMD, and more. Meanwhile, the vast application of graphics hardware in AI has propelled GPU (graphics processing unit) maker NVIDIA into tech juggernaut status: the company's shares were the best-performing stock over the past year. Also included in the analysis are 7 chip companies we identified as active in private markets, including NVIDIA, AMD, and ARM.


Benchmarking Training Time for CNN-based Detectors with Apache MXNet Amazon Web Services

#artificialintelligence

Let's start with K520s, which ships with g2.2x instances: Note that, given a constant batch size, adding extra g2.2x instances (each with one K520) results in a roughly constant speed per machine. Holding batch size constant but increasing the number of GPUs (technically reducing the individual batch size for each GPU), increases speed roughly 2.5x! We observe that when we keep the batch size constant (at 16) and increase the number of GPUs on the same machine, the resulting speed also increases roughly 2x. Getting back to the point, let's investigate training times: The expected reduction in training time when batch size increases is obvious.


Intel Proposes Its Embedded Processor Graphics For Real-Time Artificial Intelligence

#artificialintelligence

Further research told me that along with FPGA (Field Programmable Field Gate Array), there's an embedded Intel Processor Graphics for deep learning inference. Unlike the Project BrainWave of Microsoft (which only relies on Altera's Stratix 10 FPGA to accelerate deep learning inference), Intel's Inference Engine design uses integrated GPUs alongside FPGAs. However, embedded Intel's Processor Graphics and Altera's Stratix 10 FPGA could be the top hardware products for deep learning inference accelerations. Marketing its embedded graphics processors to accelerate deep learning/artificial intelligence computing is one more reason for us to stay long INTC.


Which GPU(s) to Get for Deep Learning

@machinelearnbot

With a good, solid GPU, one can quickly iterate over deep learning networks, and run experiments in days instead of months, hours instead of days, minutes instead of hours. Later I ventured further down the road and I developed a new 8-bit compression technique which enables you to parallelize dense or fully connected layers much more efficiently with model parallelism compared to 32-bit methods. For example if you have differently sized fully connected layers, or dropout layers the Xeon Phi is slower than the CPU. GPUs excel at problems that involve large amounts of memory due to their memory bandwidth.

How a new wave of machine learning will impact today's enterprise 7wData

#artificialintelligence

Advances in deep learning and other Machine Learning algorithms are currently causing a tectonic shift in the technology landscape. Betting big on an AI future, cloud providers are investing resources to simplify and promote machine learning to win new cloud customers. First, advances in computing technology (GPU chips and cloud computing, in particular) are enabling engineers to solve problems in ways that weren't possible before. For example, chipmaker NVIDIA has been ramping up production of GPU processors designed specifically to accelerate machine learning, and cloud providers like Microsoft and Google have been using them in their machine learning services.


Lessons Learned From Benchmarking Fast Machine Learning Algorithms

@machinelearnbot

A key challenge in training boosted decision trees is the computational cost of finding the best split for each leaf. However, the CPU results for BCI and Planet Kaggle datasets, as well as the GPU result for BCI, show that XGBoost hist takes considerably longer than standard XGBoost. This is due to the large size of the datasets, as well as the large number of features, which causes considerable memory overhead for XGBoost hist. As a side note, the standard implementation of XGBoost (exact split instead of histogram based) does not benefit from GPU either, as compared to multi-core CPU, per this recent paper.

Both cloud services and progress in machine intelligence have made it easier for organizations to apply AI-based functionalities to interact closer with its customers. In the context of their AI strategy, companies should evaluate AI services from different cloud providers. At the end of the day, the progressive developments of AI technologies are going to influence infrastructure environments and let them shift from a supporting mode towards a model where AI applications get the equal support like today's web applications and services. The Future Is an AI-enabled Enterprise An AI-enabled Infrastructure is an essential part of today's enterprise stack and builds the foundation for the AI-enabled enterprise.
