MLGdańsk #121 – Predicting the Unpredictable: Mathematical Models and the Covid 19 Pandemic

MLGdańsk online meeting be take place on Monday, 2022.03.07, at 18:00 CET

link to meeting:

Our speaker will be prof. Tyll Krüger

The topic of his talk is:
Predicting the Unpredictable: Mathematical Models and the Covid 19 Pandemic

Abstract of the presentation:
“Predicting the future of the COVID-19 pandemic is a challenging task and can not be done without mathematical models describing the progression of the epidemic.

Despite large uncertainties about epidemiological relevant medical and social key parameters, mathematical models can provide deep insights into the dependency of the epidemic dynamics on those parameters.

Epidemiological models can furthermore be used to develop and improve rational strategies for controlling the COVID-19 epidemics.

We focus in the talk on fundamental mathematical features of individual based epidemic models and highlight the close relation to problems in percolation and random graph theory.

We emphasize the special role of households and discuss some results and conjectures in first passage percolation and their impact on epidemic processes.

Finally we present some outcomes of the MOCOS microsimulation model for the COVID -19 epidemic in Poland and Germany and reflect on problems related to model based policy advice for epidemic control.”

Serdecznie zapraszamy!

MLGdańsk Logo

After three years of operation of our group, it’s time to take care of how we are perceived!

The first initiative related to this is the presentation of the new logo of our group.

44th meeting – introduction to RNNs

Meeting was held on 25.06.2018.

The meeting had a form of mini-course focused on Recurrent Neural Networks. The presenter was Karol Draszawka

Karol’s description of course:

“This course presents the basics of Recurrent Neural Networks (RNNs) in the context of sequence labelling problems. The need for RNNs is shown first. After that, basic RNNs architecture and the training algorithm Backpropagation Through Time (BPTT) are given in theory and implemented using Tensorflow primitives. Considatations about problems with such basic RNNs leads to the design of refined RNN architectures, such as LSTM and GRU, which are next implemented, also from Tensorflow primitives. Lastly, some examples and tips for using RNNs for real problems are given.”

Our next meeting is on 9th July 2018. All ML Enthusiasts are welcome to join us!

40½ Meeting – The Deep Learning Revolution: From Technology to Impact

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.

19th meeting – decision trees and random forest

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!

18th meeting – logic programming in Scheme / ECG signal analysis

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!


17th meeting – Alpha Go / image recognition in security domain

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!

16th meeting – abductive reasoning and Answer Set Programming

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!
