PyData Sydney Meetup: May 2019

May’s Pydata Syndey Meetup was hosted at a new venue: Optiver Asia Pacific – our sponsor for the event. Just one week after the AWS Summit the buzz from winning AWS Partner of the Year in Analytics, Data, and Machine Learning was still very present!

One of the speakers of the evening, Nick Wienholt, is a consulting data engineer and data scientist with a focus on quantitative finance and the sports gaming industry. He spoke about how to quickly scale a local Jupyter notebook using Keras and Tensorflow to train and execute on Google Cloud using specialised GPUs and TPUs.

 

Our second speaker’s, Vikram Patil, seminar mainly revolved on how data from a csv file can be transformed to dynamic web application, mainly for visualization purposes with fewer code lines. This can be achieved from shiny package, built upon R. The seminar explained – in detail – the code structure and rules to follow while developing a visualization application. Additionally, another package was also explained known as Leaflet (this package is powerful to display location data, for example, latitude and longitude details).

 

The seminar had 3 demos:

Demo 1:

The first demo explained the Rshiny visualisation. With a basic example on how histograms can be varied with an input.

 

Demo 2:

This demo explained how the Leaflet Package can be a powerful application to display the locations on a map.

Example below: various schools in Victoria state.

Data:

Below: Map on Rshiny using Leaflet

The number explains the schools inside the regions, for example, around 635 schools around Melbourne region.

 

Demo 3:

The below data in Microsoft Excel is mainly about Coral bleaching across great barrier reef.

 

Below is the web application developed through Rshiny, which displays the different coral bleaching across various sites.

 

Overall, the event was another informative and entertaining one. The pizzas and drinks were a great bonus too! Thanks to our sponsor Optiver for the opportunity and venue.
