Top libraries for Distributed Deep Learning

The performance of the neural network improves with an increasing volume of training data. With more and more devices generating data that can potentially be used for training and model generation, the models are getting better at generalizing the stochastic environment and handling complex tasks. However, with more data and more complex structures for the deep neural networks, the computational requirements increase.

Even though we have started leveraging GPUs for deep neural network training, the vertical scaling of the compute infrastructure has its own limitations and cost implications. Leaving the cost implications aside, the time it takes to train a significantly large deep neural network on a large set of training data is not reasonable. However, due to the nature and network topology of the neural networks, it is possible to distribute the computation on multiple machines at the same time and merge the results back with a centralized process. This is very similar to Hadoop, as a distributed computing batch processing engine, and Spark, as an in-memory distributed computing framework.

With deep neural networks, there are two approaches for leveraging distributed computing:

  • Model Distribution: In this approach, the deep neural network is broken into logical fragments that are treated as independent models from a computational perspective. The results from these models are combined by a central process, as depicted in this diagram:

  • Data Distribution: In this approach, the entire model is copied to all the nodes participating in the cluster and the data is distributed in chunks for processing. The master process collects the output from the individual nodes and produces the final outcome, shown as follows:

The data distribution approach is very similar to Hadoop’s MapReduce framework. The MapReduce job creates the input splits based on predefined and run-time configuration parameters. These chunks are sent to the independent nodes for processing by the map tasks in a parallel manner.

The output from the map tasks is shuffled for relevance (simple sort) and is given as input to the reduce tasks for generating intermediate results. The individual MapReduce chunks are combined to produce the final result. The data distribution approach is more naturally suitable for Hadoop and Spark frameworks and it is a more widely researched approach at this time. The deep neural networks that leverage data distribution primarily deploy a parameter-averaging strategy for training the model.

This is a simple but efficient approach for training a deep neural network with data distribution:

Based on these fundamental concepts of distributed processing, let’s review some of the popular libraries and frameworks that enable parallelized deep neural networks.

Distributed deep learning

With an ever-increasing number of data sources and data volumes, it is imperative that the deep learning application and research leverage the power of distributed computing frameworks. In this section, we will review some of the libraries and frameworks that effectively leverage distributed computing. These are popular frameworks based on their capabilities, adoption level, and active community support.

DL4J and Spark

The core framework of DL4J is designed to work seamlessly with Hadoop (HDFS and MapReduce) as well as Spark-based processing. It is easy to integrate DL4J with Spark. DL4J with Spark leverages data parallelism by sharding large datasets into manageable chunks and training the deep neural networks on each individual node in parallel. Once the models produce parameter values (weights and biases), those are iteratively averaged for producing the final outcome.

API overview

In order to train the deep neural networks on Spark using DL4J, two primary wrapper classes need to be used:

  • SparkDl4jMultiLayer: A wrapper around DL4J’s MultiLayerNetwork
  • SparkComputationGraph: A wrapper around DL4J’s ComputationGraph

The network configuration process for the standard, as well as the distributed, mode remains same. That means we configure the network properties by creating a MultiLayerConfiguration instance. The workflow for deep learning on Spark with DL4J can be depicted as follows:

Here are the sample code snippets for the workflow steps:

  • Multilayer network configuration:

MultiLayerConfiguration conf = new NeuralNetConfiguration.Builder()

.optimizationAlgo(OptimizationAlgorithm.STOCHASTIC_GRADIENT_DESCENT).iterations(1)

.learningRate(0.1)

.updater(Updater.RMSPROP)   //To configure: .updater(new RmsProp(0.95))

.seed(12345)

.regularization(true).l2(0.001)

.weightInit(WeightInit.XAVIER)

.list()

.layer(0, new GravesLSTM.Builder().nIn(nIn).nOut(lstmLayerSize).activation(Activation.TANH).build())

.layer(1, new GravesLSTM.Builder().nIn(lstmLayerSize).nOut(lstmLayerSize).activation(Activation.TANH).build())

.layer(2, new RnnOutputLayer.Builder(LossFunctions.LossFunction.MCXENT).activation(Activation.SOFTMAX)        //MCXENT + softmax for classification

.nIn(lstmLayerSize).nOut(nOut).build())

.backpropType(BackpropType.TruncatedBPTT).tBPTTForwardLength(tbpttLength).tBPTTBackwardLength(tbpttLength)

.pretrain(false).backprop(true)

.build();

  • Set up the runtime configuration for the distributed training:

ParameterAveragingTrainingMaster tm = new ParameterAveragingTrainingMaster.Builder(examplesPerDataSetObject)

.workerPrefetchNumBatches(2) //Async prefetch 2 batches for each worker

.averagingFrequency(averagingFrequency)

.batchSizePerWorker(examplesPerWorker)

.build();

  • Instantiate the Multilayer network on Spark with TrainingMaster:

SparkDl4jMultiLayer sparkNetwork = new SparkDl4jMultiLayer(sc, config, tm);

  • Load the shardable training data:

public static JavaRDD<DataSet> getTrainingData(JavaSparkContext sc) throws IOException {

List<String> list = getTrainingDatAsList(); // arbitrary sample method

JavaRDD<String> rawStrings = sc.parallelize(list);

Broadcast<Map<Character, Integer>> bcCharToInt = sc.broadcast(CHAR_TO_INT);

return rawStrings.map(new StringToDataSetFn(bcCharToInt));

}

  • Train the deep neural network:

sparkNetwork.fit(trainingData);

  • Package the Spark application as a .jar file:

mvn package

  • Submit the application to Spark runtime:

spark-submit –class fully qualified class name>> –num-executors 3 ./jar_name>>-1.0-SNAPSHOT.jar

The DeepLearning4j official website provides extensive documentation for running the deep neural networks on Spark: https://deeplearning4j.org/spark

TensorFlow

TensorFlow is the most popular library created and open sourced by Google. It uses data-flow graphs for numerical computations and deals with Tensor as the basic building block. A Tensor can simply be considered as an n-dimensional matrix. TensorFlow applications can be seamlessly deployed across platforms and it can run on GPUs and CPUs, along with mobile and embedded devices. TensorFlow is designed as a large-scale distributed training that supports new machine learning models, research, and granular-level optimizations.

TensorFlow is quick to install and start experimenting with. The latest version of TensorFlow can be downloaded from https://www.tensorflow.org/. The site also contains extensive documentation and tutorials.

Python Deep Learning tutorial: Create a GRU (RNN) in TensorFlow

Posted on September 17th, 2018

Posted by Capri Granville on January 27, 2018 at 7:00pm

Guest blog post by Kevin Jacobs.

MLPs (Multi-Layer Perceptrons) are great for many classification and regression tasks. However, it is hard for MLPs to do classification and regression on sequences. In this Python deep learning tutorial, a GRU is implemented in TensorFlow. Tensorflow is one of the many Python Deep Learning libraries.

By the way, another great article on Machine Learning is this article on Machine Learning fraud detection. If you are interested in another article on RNNs, you should definitely read this article on the Elman RNN.

 

What is a GRU or RNN?

A sequence is an ordered set of items and sequences appear everywhere. In the stock market, the closing price is a sequence. Here, time is the ordering. In sentences, words follow a certain ordering. Therefore, sentences can be viewed as sequences. A gigantic MLP could learn parameters based on sequences, but this would be infeasible in terms of computation time. The family of Recurrent Neural Networks (RNNs) solve this by specifying hidden states which do not only depend on the input, but also on the previous hidden state. GRUs are one of the simplest RNNs. Vanilla RNNs are even simpler, but these models suffer from the Vanishing Gradient problem.

[responsive_video type=’youtube’ hide_related=’1′ hide_logo=’0′ hide_controls=’0′ hide_title=’0′ hide_fullscreen=’0′ autoplay=’0′]https://www.youtube.com/watch?v=dFARw8Pm0Gk[/responsive_video]

Mathematical GRU Model

The key idea of GRUs is that the gradient chains do not vanish due to the length of sequences. This is done by allowing the model to pass values completely through the cells. The model is defined as the following [1]:

z_t = sigma(W^{(z)} x_t + U^{(z)} h_{t-1} + b^{(z)}) r_t = sigma(W^{(r)} x_t + U^{(r)} h_{t-1} + b^{(r)}) tilde{h}_t = tanh(W^{(h)} x_t + U^{(h)} h_{t-1} circ r_t + b^{(h)}) h_t = (1 - z_t) circ h_{t - 1} + z_t circ tilde{h}_t

I had a hard time understanding this model, but it turns out that it is not too hard to understand. In the definitions, circ is used as the Hadamard product, which is just a fancier name for element-wise multiplication. sigma(x) is the Sigmoid function which is defined as sigma(x) = frac{1}{1 + e^{-x}}. Both the Sigmoid function (sigma) and the Hyperbolic Tangent function (tanh) are used to squish the values between 0 and 1.

z_t functions as a filter for the previous state. If z_t is low (near 0), then a lot of the previous state is reused! The input at the current state (x_t) does not influence the output a lot. If z_t is high, then the output at the current step is influenced a lot by the current input (x_t), but it is not influenced a lot by the previous state (h_{t-1}).

r_t functions as forget gate (or reset gate). It allows the cell to forget certain parts of the state.

The Task: Adding Numbers

In the code example, a simple task is used for testing the GRU. Given two numbers a and b, their sum is computed: c = a + b. The numbers are first converted to reversed bitstrings. The reversal is also what most people would do by adding up two numbers. You start at the right from the number and if the sum is larger than 10, you carry (memorize) a certain number. The model is capable of learning what to carry. As an example, consider the number a = 3 and b = 1. In bitstrings (of length 3), we have a = [0, 1, 1] and b = [0, 0, 1]. In reversed bitstring representation, we have that a = [1, 1, 0] and b = [1, 0, 0]. The sum of these numbers is c = [0, 0, 1] in reversed bitstring representation. This is [1, 0, 0] in normal bitstring representation and this is equivalent to 4. These are all the steps which are also done by the code automatically.

The Code

The code is self-explaining. If you have any questions, feel free to ask! The code can also be found on GitHub. Sharing (or Starring) is Caring :-)!

Results

After ~2000 iterations, the model has fully learned how to add 2 integer numbers!

Conclusion (TL;DR)

This Python deep learning tutorial showed how to implement a GRU in Tensorflow. The implementation of the GRU in TensorFlow takes only ~30 lines of code! There are some issues with respect to parallelization, but these issues can be resolved using the TensorFlow API efficiently. In this tutorial, the model is capable of learning how to add two integer numbers (of any length).

Rating : 4.9 out of 5

 

Review : Very useful course. Gives great insight on the hyper parameter tuning, regularisation and optimisation. One request I have is to provide a docker image which we can use to run the exercises locally. Sometimes I found it hard to build the environment where I can run the coursework. Some of the installations are clashing and it is not clear what versions of libraries are used in the coursework environment. It sometimes requires unnecessary effort.

14. Advanced Machine Learning Certification by Higher School of Economics

A total of 21 professors and researchers have come together to create this course; and this is undoubtedly one of the most comprehensive courses on data science and machine learning. This is an intermediate level course only relevant if you have basic knowledge around the subject. The course includes CERN scientists who will share their experiences of solving real-world problems using data science. This is a 7 course curriculum, and it will take you deep into the world of machine learning.

 

Rating : 4.8 out of 5

 

Review : Great course. Teaches you a lot of techniques and hands-on assignments. The course covers extensively on how to achieve a better score in Kaggle with tips and techniques. The real-world data science would be slightly different to this. But nevertheless, the content is refreshing along with the links, supplement materials associated

15. Excel to MySQL: Analytic Techniques for Business Certification from Duke University

Taught by Jana Schaich Borg and Professor Daniel Egger, this course from Duke University will help you formulate data questions, visualize datasets and inform strategic decisions. Learn how to use Excel, Tableau and MySQL to analyze data, build models and communicate your insights. It is all followed by a project where you will apply your skills to work on a real world business process.

 

Rating : 4.7 out of 5

Review : The course was very well organized. Instead of just teaching tableau the course covered aspects about how to approach a business problem, design ways to approach a problem, structured thinking and then went to solving those problems using tableau. Even after tableau was taught the instructor covered aspects of how to present it to the target audience and make an impact. Great work. Only suggestion will be to be up to date about the content as tableau comes up with upgrades but the course videos don’t include it.

16. Data Structures and Algorithms Certification from UC San Diego

UC San Diego and Higher School of Economics along with Computer Science Center and Yandex come together for this Data Structures and Algorithms Specialization spread across 6 courses. It is taught by a group of extremely proficient professors that include Daniel M Kane, Pavel Pevzner, Michael Levin, Neil Rhodes and Alexander S. Kulikov. There’s a good mix of theory and practice in this course where you will learn algorithmic techniques for solving various computational problems. This is one of the best Algorithms online course with the wealth of programming techniques it teaches you. The program also consists of two major projects : Big Networks and Genome Assembly.

Rating : 4.6 out of 5

 

Review : Thanks for the course. Content is good and videos are very well done. Only problem is that the assignment problems were gruelling and unfortunately it is hard to get one-to-one contact for help if you get stuck

Review – The course material was presented in an easy to understand method with many examples. Covered understanding and basic equations, but not so much math that the student gets lost. The graphics , equations, and some repetition really helped capture the concepts. The homework challenges gives a chance to practice the lesson material. External references and links were good for slightly different viewpoints and explanations . Overall a great job by the team. I’ve already signed up for more of Kirill’s courses. – Frederick Wheeler

Review – The illustration is wonderful. The instructor explains the concept well. These concepts are quite complex but they are well-presented in a way that I can understand. All the exercises are great, they help me understand the concept even better. I wish that for the last section or the Assumption section there will be more exercises. I also wish that there is more explanation on the ANOVA table such as how you guys get those numbers, how to use them efficiently etc. – Huong N Le
