The USA decided to regulate the trade more by imposing tariffs on specific types of traded goods. It is therefore more interesting to find out whether the current technologies based on artificial intelligence with time series influenced by extraordinary factors such as the trade war between two powers are able to work. The objective of the contribution is to examine and subsequently equalize two time series – the USA import from the PRC and the USA export to the PRC. The dataset shows the course of the time series at monthly intervals between January 2000 and July 2019. 10,000 multilayer perceptron networks (MLP) are generated, out of which 5 with the best characteristics are retained. It has been proved that multilayer perceptron networks are a suitable tool for forecasting the development of the time series if there are no sudden fluctuations. Mutual sanctions of both states did not affect the result of machine learning forecasting.

The aim of this paper is to mechanically predict the import of the United States of America (USA) from the People's Republic of China (PRC). The trade restrictions of the USA and the PRC caused by the USA feeling of imbalance of trade between the two states have significantly influenced not only the trade between the two players, but also the overall climate of international trade. The result of this paper is the finding that multilayer perceptron networks (MLP) appear to be an excellent tool for predicting USA imports from the PRC. MLP networks can capture both the trend of the entire time series and its seasonal fluctuations. It also emerged that time series delays need to be applied. Acceptable results are shown to delay series of the order of 5 and 10 months. The mutual sanctions of both countries did not have a significant impact on the outcome of the machine learning prediction.

International trade is an important factor of economic growth. While foreign trade has existed throughout the history, its political, economic and social importance has grown significantly in the last centuries. The objective of the contribution is to use machine learning forecasting for predicting the balance of trade of the Czech Republic (CR) and the People´s Republic of China (PRC) through analysing and machine learning forecasting of the CR import from the PRC and the CR export to the PRC. The data set includes monthly trade balance intervals from January 2000 to June 2019. The contribution investigates and subsequently smooths two time series: the CR import from the PRC; the CR export to the PRC. The balance of trade of both countries in the entire monitored period is negative from the perspective of the CR. A total of 10,000 neural networks are generated. 5 neural structures with the best characteristics are retained. Neural networks are able to capture both the trend of the entire time series and its seasonal fluctuations, but it is necessary to work with time series lag. The CR import from the PRC is growing and it is expected to grow in the future. The CR export to the PRC is growing and it is expected to grow in the future, but its increase in absolute values will be slower than the increase of the CR import from the PRC.

This project considers the operational impact of Autonomous Vehicles by creating a corridor using the latest network available. The behaviour of these vehicles entering the corridor is monitored at the macroscopic level by modifying the data which can be extracted from the vehicle. This data is made to learn using machine learning called the Time Series Neural Network and the data is used as a parameter to make the vehicles Autonomous. The project resolves the location, develops and demonstrates the collision avoidance of the vehicles using Artificial Intelligence. Autonomous means the vehicles will be able to learn to act accordingly without human intervention

O bioma pantaneiro é acometido anualmente por um grande número de queimadas e incêndios. Prever esses eventos é de suma importância, uma vez que, prejuízos à fauna e à flora poderiam ser minimizados e catástrofes evitadas. Uma intervenção imediata do poder público na mitigação desses eventos passa, essencialmente, pela previsão do número de focos e das áreas queimadas, e posteriormente, na localização desses focos e na identificação das áreas. Dados precisos sobre as variáveis ambientais, em tempo real, podem ser obtidos através do sensoriamento remoto, aliado aos sistemas de informações geográficas, às técnicas de inteligência artificial e estatística aplicada, favorecendo às tomadas de decisão na previsão. O objetivo deste estudo foi aplicar a técnica de Redes Neurais Artificiais (RNAs) para a previsão dos focos e das áreas queimadas no Pantanal Sul-Mato-Grossense. O centro de previsão de tempo e estudos climáticos do Instituto Nacional de Pesquisas Espaciais (INPE), bem como, o Instituto Nacional de Meteorologia (INMET) possuem bancos de dados do Pantanal, dos quais, as variáveis envolvidas nesse processo foram extraídas. Utilizando as RNAs do tipo Multilayer Perceptron, com algoritmo Retropropagation de aprendizagem foi possível prever o valor do número de focos com um ajuste de 84,8% utilizando um conjunto de variáveis meteorológicas como preditoras e, de 99,4% usando como preditora, somente a série temporal do número de focos. No entanto, o ajuste passou a ser 90,3% ao se realizar a previsão da área queimada, utilizando as mesmas variáveis, e de 98,6%, usando como preditora, somente os dados da área queimada.  A B S T R A C TOn a year basis the Pantanal biome is affected by a large number of fires and fire points. Predicting these events is of paramount importance, since damage to fauna and flora could be minimized and disasters might be avoided. Immediate intervention of the government in mitigating these events essentially depends on the identification and location of fire outbreaks. Accurate and reliable data on environmental variables in real time can be obtained by means of remote sensing coupled with geographic information systems, techniques of artificial intelligence and applied statistics, which would favor the decision-making in foreseeing fire foci and burned area. The aim of this study was to apply the technique of artificial neural networks to predict the fire foci and burned areas in the Pantanal Sul-Mato-Grossense. The center for weather forecast and climate studies of the National Institute for Space Research (INPE) and the National Institute of Meteorology (INMET) afford meteorological database of the Pantanal region, from which the environmental variables involved in this process were extracted. By using Multilayer Perceptron Artificial Neural Networks with Backpropagation algorithm, it was possible to predict the value of the number of fire foci with an adjustment of 84,8% using a set of meteorological variables as predictors and of 99,4% using as a predictor only the time series of the number fire foci.  However, the adjustment became 90,3% when the forecast of the burned area, using the same meteorological variables, and 98,6%, using as a predictor, only the time series of the burned area.Keywords: fire forecasting, environmental monitoring,artificial intelligence.

Mutual trade restrictions between the USA and the PRC caused by the USA feeling of imbalance of trade between these two countries have significantly influenced not only the trade between these two states but also the overall atmosphere of the international trade in the last few years. The objective of the contribution is to find out whether machine learning forecasting is capable of equalizing time series so that the model effectively forecasts the future development of the time series even in the context of an extraordinary situation caused by such factors as the mutual sanctions of the USA and PRC. The dataset shows the course of the time series at monthly intervals starting from January 2000 to June 2019. There is regression carried out using neural structures. Three sets of artificial neural networks are generated. They are differ in the considered time series lag. 10,000 neural networks are generated, out of which 5 with the best characteristics are retained. The mutual USA and PRC sanctions did not affect the success rate of the machine learning forecasting of the CR import from the PRC. It is evident that the mutual sanctions shall affect the trade between the CR and the PRC.

Genomic analysis and digitalization of medical records have led to a big data scenario within hematopathology. Artificial intelligence and machine learning tools are increasingly used to integrate clinical, histopathological, and genomic data in lymphoid neoplasms. In this study, we identified global trends, cognitive, and social framework of this field from 1990 to 2020. Metadata were obtained from the Clarivate Analytics Web of Science database in January 2021. A total of 525 documents were assessed by document type, research areas, source titles, organizations, and countries. SciMAT and VOSviewer package were used to perform scientific mapping analysis. Geographical distribution showed the USA and People’s Republic of China as the most productive countries, reporting up to 190 (36.19%) of all documents. A third-degree polynomic equation predicts that future global production in this area will be three-fold the current number, near 2031. Thematically, current research is focused on the integration of digital image analysis and genomic sequencing in Non-Hodgkin lymphomas, prediction of chemotherapy response and validation of new prognostic models. These findings can serve pathology departments to depict future clinical and research avenues, but also, public institutions and administrations to promote synergies and optimize funding allocation.
