Raspberry Pi Bee Health Monitoring Device
Jakub Nevlacil, Simon Bilik, Karel Horak
A declining honeybee population could pose a threat to a food resources of the whole world one of the latest trend in beekeeping is an effort to monitor a health of the honeybees u…
Towards Phytoplankton Parasite Detection Using Autoencoders
Simon Bilik, Daniel Batrakhanov, Tuomas Eerola +9
Phytoplankton parasites are largely understudied microbial components with a potentially significant ecological impact on phytoplankton bloom dynamics. To better understand their i…
Machine Learning and Computer Vision Techniques in Continuous Beehive Monitoring Applications: A survey
Simon Bilik, Tomas Zemcik, Lukas Kratochvila +4
Wide use and availability of the machine learning and computer vision techniques allows development of relatively complex monitoring systems in many domains. Besides the traditiona…
Feature space reduction as data preprocessing for the anomaly detection
Simon Bilik, Karel Horak
In this paper, we present two pipelines in order to reduce the feature space for anomaly detection using the One Class SVM. As a first stage of both pipelines, we compare the perfo…
SIFT and SURF based feature extraction for the anomaly detection
Simon Bilik, Karel Horak
In this paper, we suggest a way, how to use SIFT and SURF algorithms to extract the image features for anomaly detection. We use those feature vectors to train various classifiers…
Visual diagnosis of the Varroa destructor parasitic mite in honeybees using object detector techniques
Simon Bilik, Lukas Kratochvila, Adam Ligocki +5
The Varroa destructor mite is one of the most dangerous Honey Bee (Apis mellifera) parasites worldwide and the bee colonies have to be regularly monitored in order to control its s…
Solving Zero-Sum One-Sided Partially Observable Stochastic Games
Karel Horák, Branislav Bošanský, Vojtěch Kovařík +1
Many security and other real-world situations are dynamic in nature and can be modelled as strictly competitive (or zero-sum) dynamic games. In these domains, agents perform action…
Discovering Imperfectly Observable Adversarial Actions using Anomaly Detection
Olga Petrova, Karel Durkota, Galina Alperovich +4
Anomaly detection is a method for discovering unusual and suspicious behavior. In many real-world scenarios, the examined events can be directly linked to the actions of an adversa…
Compact Representation of Value Function in Partially Observable Stochastic Games
Karel Horák, Branislav Bošanský, Christopher Kiekintveld +1
Value methods for solving stochastic games with partial observability model the uncertainty about states of the game as a probability distribution over possible states. The dimensi…
Computing Maxmin Strategies in Extensive-Form Zero-Sum Games with Imperfect Recall
Branislav Bosansky, Jiri Cermak, Karel Horak +1
Extensive-form games with imperfect recall are an important game-theoretic model that allows a compact representation of strategies in dynamic strategic interactions. Practical use…
Dynamic Programming for One-Sided Partially Observable Pursuit-Evasion Games
Karel Horák, Branislav Bošanský
Pursuit-evasion scenarios appear widely in robotics, security domains, and many other real-world situations. We focus on two-player pursuit-evasion games with concurrent moves, inf…
