MLGdańsk #131 – Legal Document Summarization and AI Explainability

MLGdańsk online meeting will be held on Monday, 2022.09.19, at 18:00 CEST.

link to the meeting:

Our speaker:
Claudia Schulz, PhD
Thomson Reuters Labs

The topic of the talk is:
Legal Document Summarization and AI Explainability

“Legal research is a highly manual and time-consuming process. Legal professionals, for example, have to read court cases that are up to 100 pages long, just to identify the most important aspects in order to decide whether their firm should represent the case.

Natural Language Processing (NLP) techniques like information extraction and summarisation thus provide great opportunities to save law firms time. However, applying NLP to legal documents is highly challenging due to the domain-specific terminology and variability in the legal document layout.

In this talk, we show how Thomson Reuters Labs tackles these challenges and present our work on summarising court cases and providing human-understandable explanations thereof.”

The meeting is open to all interested – feel free to join!

MLGdańsk #130 – AI Governance, Standards and Regulation for a Trustworthy AI ecosystem

MLGdańsk online meeting will be held on Monday, 2022.09.05, at 18:00 CEST.

link to the meeting:

Our speaker:
Dr. Ansgar Koene
Global AI Ethics and Regulatory Leader at EY

The topic of the talk is:
AI Governance, Standards and Regulation for a Trustworthy AI ecosystem

“The increasing use of algorithmic decision-making technologies (colloquially referred to as “AI”) in industry, commerce and public service provision are giving rise to concerns about potential negative impacts on individuals (e.g. algorithmic discrimination bias) and the wider socio-economic fabric of society (e.g. displacement of jobs).

With trust in the technology being cited as a key barrier for successful deployment, both in the public and private sector, there is a growing push toward translating AI ethics principles into actionable practice.

This talk will review current initiatives towards the development of AI governance frameworks, ethics and oversight related standards and regulations, and discuss the role each of these can play within a wider ecosystem of trustworthiness for the use of AI.”

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.”

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!

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.
