November meetup: analytics for mobile gaming

If you ever wondered how the processing and analytics architecture for +80000 mobile games looks like – we have an answer for you! RSVP here and join the Big Data Community on November 7, when Ioana Hreninciuc, CEO of GameAnalytics, will present how they built such an architecture with a handful of engineers. The architecture includes Druid Imply, Kinesis, EMR Spark, and also Big Query.

Event agenda

  • 6:30 PM – gathering
  • 7:00 PM – 8:00 PM Analytics for 1 billion players per month, Ioana Hreninciuc @ GameAnalytics

“How we built an entirely new backend to do ad-hoc analytics for +80,000 mobile game studios, aanalyzing+1 billion players per month, with super high-cost efficiency and just a handful of developers.”
Ioana Hreninciuc, the CEO of GameAnalytics, will go into details about the company’s backend systems, cloud infrastructure, and approach to data processing, to showcase how even small engineering teams can build high performance, large scale systems.

ML on Spark workshop

The Big Data community is coming back in November with a new workshop on Machine Learning – this time with how to build a model using Spark ML logistic regression and gradient boosting. RSVP here to save your front row spot on November 5, starting at 14:00!

 

About the workshop

Come join us for an afternoon in which we will explore Apache Spark’s Machine Learning capabilities. We’ll be looking at using Spark to build a Credit Scoring model which estimates the probability of default for current and existing customers.

Agenda

1. Intro, problem description and setup
2. Loading data
3. Exploratory data analysis
4. Feature engineering
5. Building our first model
6. Testing and validation
7. Improving the model with cross-validation and hyper-parameter tuning
8. Deployment
9. Considerations for running in production

 

Prerequisites

Bring your laptop! Beyond that, the only requirement is a web browser. We will be using a managed Spark platform, called Azure Databricks, for the lab. We will provide access to Azure Databricks and everything else you need.

September meetup: Hadoop on Raspberry PI, Elasticsearch vs Solr

Join us to talk about a Hadoop data lake built on a 3 nodes Raspberry PI cluster and continue with an update on Elasticsearch and Solr use cases and their differences. RSVP here to save your front row spot on September 26, starting at 18:30!

 

Event agenda

  • 18:30 – 19:00 Registration

 

  • 19:00 – 19:40 Hadoop Data Lake setup, Andrei Daneasa @ EndavaAndrei is working in IT for more than 19 years. He started from the development area and moved gradually towards architecture, BI, Analytics and Big Data. He is Lead Data Consultant in Endava for almost 3 years. His talk will be focused on processing and visualization of data on a Raspberry PI 3-node Hadoop cluster.

 

  • 19:40 – 20:20 M Elasticsearch and Solr for Search and Real-Time Analytics, Radu Gheorghe @ SematextElasticsearch and Solr are used nowadays for a variety of use-cases. Originally, it was product search, but even that goes beyond pure keyword search: autocomplete, did-you-mean, facets, recommendations, more-like-this are all features found in E-commerce. Then there’s time-series analytics, meant to derive insights from logs, metrics, social media, and everything else with a timestamp.

    We will begin with a demo to introduce both search engines and see where they’re similar and where they differ. Then, we’ll discuss different use-cases and how you can solve them using Elasticsearch and/or Solr.

 

  • 20:20 21:00 Networking

Meetup July: Space, data and satellites

The Bucharest Big Data community will have a previous speaker to talk about Big Data/ HPC processing in the space domain. RSVP here to save your front row spot on July 24, starting at 18:30!

 

About the event

Left for vacation but didn’t check the weather? Too bad. Come to this meet-up to learn about the HPC/Big Data technology behind various numerical weather prediction systems, powered by the MTG (Meteosat Third Generation) project from EUMETSAT, how it works, the challenges, the applications of it in the industry and how that impacts you. Expect to learn about an alternative way to do Big Data/HPC processing in the context of software for the Space domain, using solutions like: Lustre/GPFS, Slurm, Heron, Spring, Jgroups, Drools, Artemis. Come and see how!

 

Event agenda

  • 18:30 – 19:00 Gathering
  • 19:00 – 20:00 Space, data, satellites and everything nice, Catalin Zamfir @ Thales Alenia Space.
  • 20:00 21:00  Networking

June meetup: machine learning, blockchain and big data

Join us to learn how about how to productionize machine learning and get a perspective on blockchain and big data. RSVP here to save your front row spot on June 5, starting 18:30!

 

About the event

Usually a machine learning project ends at evaluating the model: Do we have acceptable accuracy? Good. Now what?! The value of a ML model though is making accurate predictions for the users, deploying and maintaining the model should be easy and automated. But how?

We will answer these questions by:
– preparing Jupyter notebooks for production as reusable code blocks
– creating an ML workflow
– and finally serving online, at scale predictions using Lentiq Model Server.
Along the way, we will use Lentiq, Spark, Jupyter, MLeap, Flask, Kubernetes.

Blockchains and Big Data play well together. One can look at a blockchain like just a new kind of distributed database and, at the same, realize that the trust minimizing assumptions present in these systems can unlock additional value for ‘regular’ big data projects – either by offering an alternative to centralized storage or by easing the process of providing data and training models.

 

Event agenda

  • 18:30 – 19:00 Registration
  • 19:00 – 19:40 Productionizing Machine Learning, Cosmin Pintoiu & Costina Batica @ Lentiq
  • 19:40 – 20:10 Technology showdown: database vs blockchain, Felix Crisan, Netopia
  • 20:10 21:00 Networking
