Pitfalls of Emotion detection in production
Implementing a deep neural network in production environments presents several challenges, including defining the architecture, training the models, and developing an application. This talk will demonstrate some of the challenges faced, and how you can navigate the terrain of deep learning in real world applications.
Statistical vs. Deep Learning Methods for Time Series Forecasting
In recent years, Deep Learning (DL) has revolutionized many fields such as image analysis, speech recognition, and natural language processing. However, Time Series Analysis is still dominated by classical statistical methods. In a recent comparison of statistical (Stat) and machine learning (ML) forecasting methods, prof. Makridakis, one of the leading authorities in this field, even claimed: „The forecasting accuracy of the best ML method was lower than the worst of Stat ones while half the ML methods were less accurate than a random walk“ (Makridakis et al., PLOS One, 2018).In this talk, we start by a high-level introduction to time series forecasting. Next, we get an overview of M1 – M4 competitions‘ results and publicly available datasets on Kaggle. We propose an explanation why for some data, DL forecasting methods are superior, while on the other datasets, they cannot compete with Stat methods. And what can help you to choose in an era of automatically generated time series all around.
Travelling salesman problem is NP-hard? No Problem!
But in this talk we take optimization seriously. I will talk about our experience in two Kaggle competitions (https://www.kaggle.com/c/traveling-santa-problem, https://www.kaggle.com/c/traveling-santa-2018-prime-paths), which were related to Travelling salesman problem (TSP). I will talk about main approaches for solving TSP and also how to show that solution is almost optimal. Then we discuss implications of variations encountered at above mentioned Kaggle competitions.
Vlado Boza has a PhD in bioinformatics from Comenius University. He is very passionate about efficient algorithms and optimization problems. Works at CEAI as ML lead. Currently, he is trying to detect cough from sound recordings. Won some money from Kaggle and is Competition Grandmaster there. Loves Rust. Dislikes Scala.

How AI helps robots to see and manipulate objects (Michal Malý)
Humans are perfect at object handling. For a very long time, industrial robots were doing only simple, hard-coded manipulation. High-quality 3D scanning enabled us to localize objects precisely, and plan their picking and movement to avoid collisions. Localization and picking are tasks that we are currently solving with both analytical and ML approach. We compare the advantages and disadvantages of the approaches.
Michal (34) received his PhD in the field of Computer Science, Artificial Intelligence at FMFI UK in 2013. He is an expert in construction of rational agents based on reinforcement learning. He also worked in the area of computer security and published an innovative solution of secure distributed computing. He is currently Director of AI in Photoneo. His vision is to improve computer understanding of 3D environment and enhancing comprehension of real-world objects.
Towards Interfaces in Natural Language (Zuzana Nevěřilová)
Smart search as an essential part of the Konica Minolta Cognitive Hub needs to “understand” search queries in English. Being very different from what we use for searching the Web, smart search uses natural language processing and machine learning methods to detect the user’s intent. Afterwards, it extracts all the information the user mentions and creates relationships with the internal knowledge base. The talk will present methods Konica Minolta uses in the natural language query parser and discuss the challenges in creating natural language interfaces.
Zuzana Nevěřilová finished her PhD at Masaryk University in Brno in 2014. She works as a researcher at the Natural Language Processing Centre at Masaryk University where she focuses on knowledge bases and semantics. From June 2018, she is member of the Konica Minolta Laboratories Europe.

Machine Learning Challenges in DNA Sequencing (Tomáš Vinař)
MinION is a pocket-sized device that plugs into a USB port of your computer and can decipher your DNA. The device measures changes in electric current as DNA molecules pass through nanopores, resulting in sequences of current measurements called squiggles. It turns out, that interpreting these squiggles is neither easy nor fast. In fact, machine learning methods are the key to bringing this device to Africa to monitor most recent disease outbreaks, or to the desk of your medical practitioner to determine personalized medical treatments.
Tomáš Vinař has studied PhD at the University of Waterloo in Canada, after which he has spent some time at Cornell University in USA as a postdoc. Currently, he is an associate professor and one of the principal investigators of the Computational Biology Research Group at the Faculty of Mathematics, Physics and Informatics of Comenius University in Bratislava. Besides doing bioinformatics research in collaboration with biologists, he teaches bioinformatics, machine learning, and algorithms.
Can deep neural networks be used on embedded devices? (Marián Beszédeš)
Usage of deep neural networks is often connected to powerful (multi)GPU machines. However, we want to use their potential on every piece of hardware, even on mobile phones. It is still not straightforward to use them on embedded devices because of their size, resource consumption, performance and the like.
Nevertheless, there are techniques which can be used to make deep neural networks and embedded devices more compatible. We will talk about specialized neural networks architectures, quantization, mobile platform optimized NN libraries and even more.

Využitie machine learningu v tvárovej detekcii a verifikácii (Marián Beszédeš)
The role of optimization in Machine Learning (Dominik Csiba)
Optimization is a key component of most of the machine learning methods. Current problems often feature large amounts of high-dimensional data fitted by a complex non-convex model, such as deep learning, which are very difficult to learn efficiently. Novel approaches arise every month to tackle these problems, but the training time is often still unsatisfactory. In this talk, I will present a few scenarios, where optimization is the main bottleneck – featuring questions such as: “What kind of problems are difficult for deep learning?”. The talk is aimed for general technical audiences, everybody is welcome!
