Scala Machine Learning Projects

Overview of this book

Machine learning has had a huge impact on academia and industry by turning data into actionable information. Scala has seen a steady rise in adoption over the past few years, especially in the fields of data science and analytics. This book is for data scientists, data engineers, and deep learning enthusiasts who have a background in complex numerical computing and want to know more hands-on machine learning application development. If you're well versed in machine learning concepts and want to expand your knowledge by delving into the practical implementation of these concepts using the power of Scala, then this book is what you need! Through 11 end-to-end projects, you will be acquainted with popular machine learning libraries such as Spark ML, H2O, DeepLearning4j, and MXNet. At the end, you will be able to use numerical computing and functional programming to carry out complex numerical tasks to develop, build, and deploy research or commercial projects in a production-ready environment.

Algorithms, tools, and techniques


Large-scale data from release 3 of the 1000 Genomes project contributes to 820 GB of data. Therefore, ADAM and Spark are used to pre-process and prepare the data (that is, training, testing, and validation sets) for the MLP and K-means models in a scalable way. Sparkling water transforms the data between H2O and Spark.

Then, K-means clustering, the MLP (using H2O) are trained. For the clustering and classification analysis, the genotypic information from each sample is required using the sample ID, variation ID, and the count of the alternate alleles where the majority of variants that we used were SNPs and indels.

Now, we should know the minimum info about each tool used such as ADAM, H2O, and some background information on the algorithms such as K-means, MLP for clustering, and classifying the population groups.

H2O and Sparkling water

H2O is an AI platform for machine learning. It offers a rich set of machine learning algorithms and a web-based data processing...
