ML Gdańsk together with HACKER:SPACE Trójmiasto
has organized Machine Learning Hackathon in Gdańsk. This event has been sponsored by PredictX
. It was very energetic and collaborative meeting:
- 2 coaches,
- 20 attendees,
- 2 different problems (classification & regression),
- 6 hours of collaboration and networking.
– general info about the sponsor – PredictX
– introduction to classification, PhysioNet
– Marcin – introduction to time series analysis.
– Ramp-up with data & problems.
– Pizzas + hamburgers + salads.
– Working on problems.
– Presentation of results.
All attendees has decided on classification problem:
Few solutions have accuracy in the range of 60-75%.
However, it is difficult to compare with the official final result of the challenge (83%), because the participants tested it on the basis of a non-standard train / test split.
Hackathon summary on Piotr W. blog (in Polish):

10 May (Thursday) – special meeting, due to the special guest – Chris Rowen – who visited Gdańsk and presented passionate talk about the machine learning revolution, accelerating startups, and especially about his new startup – BabbleLabs.
Chris is a well-known Silicon Valley entrepreneur and technologist, now serving as co-founder and CEO of BabbleLabs. He has led Cognite Ventures, a specialized analysis, investment and advisory company for deep learning start-ups. He has served as CTO for Cadence’s IP Group, where he and his team develop new processor and memory for advanced applications in mobile, automotive, infrastructure, deep learning and IoT systems. Chris joined Cadence after its acquisition of Tensilica, the company he founded to develop extensible processors. He led Tensilica as CEO and later, CTO, to become one of the most prolific embedded processor architectures.
Before founding Tensilica in 1997, he was VP and GM of the Design Reuse Group at Synopsys. Chris also was a pioneer in developing RISC architecture and helped found MIPS Computer Systems, where he was VP of Microprocessor Development. He holds an MSEE and PhD in electrical engineering from Stanford and a BA in physics from Harvard. He holds more than 40 US and international patents. He was named an IEEE Fellow in 2015 for his work in development of microprocessor technology.
The first meeting of MLGdańsk group in the New Year was on 15th of January 2018.
This time we discussed about Capsule Networks – quite hot topic in ML world at the moment. The lecture on this subject was given Piotr Chlebek. We will definitely revisit this topic in the future!
Piotr’s presentation: MLGdansk34 – Capsule Networks
Our next meeting is planned on 29th of January 2018.
Meeting was held on 5.06.2017.
Łukasz Czekaj gave lecture about Bayesian modelling. He described thoroughly the concept and the most popular approaches (Bayesian networks, Bayesian hierarchical models). Łukasz also presented how to use JAGS framework to build and run those kinds of models.
Our next meeting will take place in two weeks. Feel free to join us!
The 20th meeting of our group took place on 22th of May.
The topic of the meeting was Support Vector Machines. It was thoroughly described by Krzysztof Czarnowski. The presentation was followed by interesting discussion about some mathematical details of those algorithms.
Next meeting will be held on 5th of June.
During our 19th meeting on 8th of May, Marcin Zadroga talked about decision trees and random forest methods.
Marcin described the concepts and intuitions which are basis for those popular algorithms. Also the methods like bagging and boosting were discussed.
Next meeting of our group will be held on 22nd of May. Join us!
On 24th of April 2017 we had 19th meeting of our group.
Two topics were presented. First presenter was Maciej Godek, who talked about logic programming in Scheme. He also showed us some programs he created – neural networks and genetic algorithm implementations. Additionally, Maciej presented the framework for creating virtual robots.
Second presentation was delivered by Kuba Domaszewicz. The topic of this talk was ECG signal analysis. Methods described by Kuba are used in aidlab device (health tracking wearable assistant).
Next meeting will be held on 8th of May. Feel free to join us!
Our 17th meeting was on 3rd of April 2017.
This time we had opportunity to listen to two speakers. The first – great – presentation was presented by Karol Draszawka, who with extraordinary diligence and enthusiasm discussed the intricacies of AlphaGo algorithm. Thanks to Karol, we learnt about the details and structure of five neural networks created by Google to defeat the masters of Go. The presentation was based on the article “Mastering the game of Go with deep neural networks and tree search“.
The second speaker was Piotr Orzechowski from Trineo company from Gdynia. He gave us an overview of the tasks for which image recognition algorithms are used in the security domain.
Our next meeting will be held on 24th of April 2017. See you!
During our 16th meeting on 20th March, Robert Różański presented his PhD dissertation summary.
Subject of his dissertation is „Automation of metabolism research using abstraction logic programming” which he wrote while studying at the University of Manchaster.
Robert described assumptions and results of abductive reasoning in logic programming and paradigms of Answer Set Programming in search problems.
Thanks to Robert we were also able to grasp the basics of logic programming using such tools as gringo and clasp.
Our next meeting will be held on 3rd April. The main topic for our next meeting will be Google Algorithm for Alpha Go. Feel free to join us!
