Charles is a Lead ML platforms engineer at MavenCode. He has well over 15 years of experience building large-scale, distributed applications. He has always been interested in building distributed systems. He has extensive experience working with Scala, Python on Apache Spark. Most recently he’s been working on Machine Learning Workload containerization and deployment on Kubernetes.

When it comes to Large Scale data processing and Machine Learning, Apache Spark is no doubt one of the top battle-tested frameworks out there for handling batched or streaming workloads.  The ease of use, built-in Machine Learning modules, and multi-language support makes it a very attractive choice for data wonks. However bootstrapping and getting off the ground could be difficult for most teams without leveraging a Spark cluster that is already pre-provisioned and provided as a managed service in the Cloud, while this is a very attractive choice to get going, in the long run, it could be a very expensive option if it's not well managed.


As an alternative to this approach, our team has been exploring and working a lot with running Spark and all our Machine Learning workloads and pipelines as containerized Docker packages on Kubernetes. This provides an infrastructure-agnostic abstraction layer for us, and as a result, it improves our operational efficiency and reduces our overall compute cost. Most importantly, we can easily target our Spark workload deployment to run on any major Cloud or On-prem infrastructure (with Kubernetes as the common denominator)  by just modifying a few configurations.


In this talk, we will walk you through the process our team follows to make it easy for us to run a production deployment of our Machine Learning workloads and pipelines on Kubernetes which seamlessly allows us to port our implementation from a local Kubernetes set up on the laptop during development to either an On-prem or Cloud Kubernetes environment

As the size of data generated grows exponentially in different industries such as Healthcare, Insurance, Financial Services, etc. A common challenging problem faced across this industry verticals is how to effectively or intelligently identify duplicate or similar entity profiles that may belong to the same entity in real life, but represented in the organization's datastore as different unique profiles. This could happen due to many reasons, from companies getting acquired or merging, to users creating multiple profiles or streaming data coming in from different marketing campaign channels. Organizations often wish to identify and deduplicate such entries or match up two records present in their datastore that are nearly identical (i.e. records that are fuzzy matches). This task presents an interesting challenge from the standpoint of computational complexity - with a very large dataset (> ~10 million) doing a brute force element-wise comparison will result in a quadratic complexity and is clearly not feasible from a resource and time perspective in most cases. As such, different approaches have been developed over the years including those that utilize (among others) regressions, machine learning, and statistical sampling. In this talk, we will discuss how we have used the Bayesian statistical sampling approach at scale to match records using a combination of KD-tree partitioning for efficient distribution of datasets across nodes in the Spark cluster, attribute similarity functions, and distributed computing on Spark.
