University of Warsaw and launch Google- powered project Nokia wins its largest ever GSM-Railway contract with Polish company R esearchers from the University of Warsaw, Google AI and take on a new reinforcement learning challenge on Cloud TPU hardware accelerators. The goal of the experiment is to end-to-end train an artificial intelligence to play video games fully inside a computation graph. A team from the University of Warsaw, made up of Piotr Miłoś, Błażej Osiński and Henryk Michalewski, has started a collaboration on reinforcement learning research with Łukasz Kaiser from the Google Brain team and with researchers from This project is connected to a research programme on RL that started last year. / In the experiment, an artificial intelligence will be end-to-end trained to play video games fully inside a computation graph. Assuming that a game simulator would also be a part of the graph, this could make tasks such as training AI to play video games even faster than what’s team achieved last year. The intent is to run the training process entirely on Cloud TPUs, which are new machine learning accelerators designed by Google. This will save time previously spent on communication between accelerators and a host computer. The main experiments are being run on Cloud TPUs via the TensorFlow Research Cloud programme and supported by Google Warsaw’s Antonio Gulli, Ignacy Kowalczyk and Maciej Pytel, who are helping to deploy experiments on the Google Cloud Platform. TFRC provides ML researchers with access to second-generation Cloud TPUs, each of which provides 180 teraflops of machine learning acceleration. N okia, together with its partners Herkules, Pozbud and Wasko, and Poland’s state-owned railway operator PKP Polskie Linie Kolejowe SA (PKP PLK) have signed a five-year contract to deploy a nationwide turnkey GSM-R and mission-critical backhaul network to enhance railway security and reliability throughout the country. This project, Nokia’s largest-ever GSM-R contract, will provide PKP/PLK with one of the biggest state-of-the-art railway communications networks in Europe. The new network will enable the PLK railway company to fulfil European Union requirements for ERTMS (European Rail Traffic Management System), the bloc’s European-wide standard for railway signalling. The project is majority funded by the EU and complemented by Polish State funds. GSM-R is a mandatory part of the ERTMS, which is under deployment across Europe to help rail operators like PKP PLK seamlessly manage and control trains in combination with the European Train Control System. The solution delivered by Nokia will help PKP PLK increase train traffic reliability and s Y]K[[X][B[\ݚ[\[\]\٘X[ۋXH[ݚYH[[][ۋ[Z\[ۚ[\ \\H[Yܘ][ۋ\ [[H\H[XZ[[[H܂L HوHKT]ܚ\›[ܙH[ LK HوX[XKB\YX][]ܚ[\X\B]T][\X[][ T “TH[[H][[]\[ۂ][\^[ JHX[]ܚ™\]Z\Y[ ][Y\[[ ]Y[KT][ۈ Y[[ܙH]ܚš[Y[]X Y\Y[[]\B\ \\HXK[T STܙB]ܚX\]H[HXB܈HXK[X]ܚˈ\[\ޘY[\[H\ۜXH܂][ܚ[Y[ۜX[ۈܚ܂^Z[XKSSQSSŒM
