Designing AI Futures: A Symbiotic Vision

The new “AI spring” of Machine Learning and Deep learning, backed by Big Data and immense computational power, is opening up potential for innovation of new drugs, medical diagnosis, social robots, ‘Robo-Nurse’ and virtual assistants, but there are also imponderable existential downsides and deep anxiety that AIs are going to take over our jobs, our interaction with societal institutions and our lives. With the accelerated integration of powerful artificial intelligence systems into core social institutions and in our everyday lives, we are confronted with an electronic world where digital bots or electronic ‘agents’ are already representing us in our interactions. We face a challenge of the untamed integration of AI to come up with possible human-machine futures that mitigate the impact of the instrumental models of AI tools and systems. How can we transcend ‘machine thinking’ to mold technological futures for the common good? We need to address questions such as, can we harness collective intelligence as a transforming tool for addressing unpredictable problems of complex social systems? What are the possibilities and limitations of designing creative intelligent systems that are shaped by purpose and judgment, transcending instrument reason of the causal model? The talk will explore these issues, drawing upon current AI narratives of the relations between society and the scientific project of AI and the challenges it poses for us to come up with possible symbiotic AI futures.

Artificial Intelligence: Issues, Challenges, Opportunities and Threats

The world is experiencing a period of instability in a range of pillar institutions in the international system. These instabilities and unsustainable systems may have serious implications for humanity. Catastrophic physical phenomena are on the rise, lately and many say that this is due to human disrespect to the environment. Urgently valuable and sustainable solutions are needed. One scientific approach to address these challenging questions is Artificial Intelligence (AI). Theories of AI are reviewed. Machine learning (ML), Neural Networks (NN) and Deep Learning (DL) are briefly presented. Certain criticisms of AI and DL are carefully analyzed. A number of challenges and opportunities of AI are identified. The future of AI and potential threats of it are discussed. Artificial Intelligence (AI) and Deep Learning (DL) are relying mainly on data analysis without taking into consideration the human nature. Theories of Fuzzy Cognitive Maps (FCM) seem to provide a useful tool in developing new AI theories answering this problem.

Modeling and Optimization of Proactive Management of the Production Pollutions in the Conditions of Information Asymmetry

On the basis of the constructed mathematical model, an analysis is made of which of the instruments for regulating industrial emissions of enterprises - environmental standards or quotas sold for industrial emissions of pollutants - allows minimizing the total costs of the strategy of environmental regulation. The necessity of taking into account the asymmetry of information support of the optimization process is shown. It has been proved that the environmental policy regulator, aiming to limit the aggregate level of emissions of a given pollutant by several enterprises, can minimize total costs by applying enterprise-specific environmental standards. The system of quotas sold for production emissions allows minimizing the total costs of the strategy of environmental and economic regulation only if the costs of the environmental audit are the same for all enterprises. It is established that in the event that the cost of implementing penalties varies between enterprises, the competitive market for emission allowances will not minimize the total costs of providing the total amount of emissions for a certain level, allowing a certain degree of non-compliance with environmental requirements.

Making a Choice of Resulting Estimates of Characteristics with Multiple Options of Their Evaluation

The paper dwells on the analysis of the efficiency of different algorithms for numerical expert data processing. Five methods were chosen for comparison: (1) on the basis of mean values; (2) on the basis of mean values with regard to experts’ competence assessment; (3) by means of getting average values on the basis of the maximum likelihood estimation method; (4) by means of getting median values on the basis of the maximum likelihood estimation method; (5) by means of getting median values on the basis of the least squares method. A complex criterion, based on evaluation of the degree of experts’ opinion consistency, the degree of closeness of the obtained results to their true values and the degree of convenience of the obtained results for solving specific tasks, is chosen as an efficiency criterion. The paper presents procedures of estimation of the mentioned components of the complex criterion and derivation of a complex estimate on the basis of known estimates of individual components. The experiment showed that, in the context of assessment of importance of individual PC components under the process of information security provision, the best result of the expert data processing is obtained with the use of the maximum likelihood estimation method on the basis of mean values, and the worst result is obtained with the use of the classical processing method on the basis of mean values. It is proposed to apply a procedure of getting a resulting estimate on the basis of a balanced consideration of the estimates obtained through different methods.

Big Data in the Stochastic Model of the Passengers Flow at the Megalopolis Transport System Stops

The problem of the passengers flow model development is proposed as the subsystem of the general municipal passengers transport system operation model of megalopolis. The specific features of the application subject (Volgograd city, Russia) were detected to simplify the big data simulation problem. The difficulties caused by the high dimensionality were overcome by means of the double time scaling in passengers’ flow estimation. The hour time scale was accepted to the computation of the hourly flow from each departure stop to the city district of destination without the pointing of the specific destination stop. The minute time scale was accepted to distribute the hourly flow between the destinations stops located in this district. The algorithms of the destination stops choice simulation were carried out. The follows examples of simulation results are presented: hourly passengers flow directed to the departure stops; daily variations of districts population caused by the inter-district passengers’ flows; influence of the of competition on the municipal transport system operation; destination stops choice variants according to the stops’ attractiveness scores designed by experts.

Networkalization of Network–Unlike Entities: How to Preserve Encoded Information

More than for twenty years network science with complex networks as its basic component has brought the idea to analyze a wide spectrum of entities through a focus on relations between the actors and has implemented the concomitant powerful instruments of the analysis. Some entities (objects, processes, and data) with their intrinsic web nature might be interpreted as networks naturally. Network ontology of another family, Network–Unlike Entities, e.g. spatial and temporal ones, is severely ambiguous and encounters with tough problems on the way to convert data into networks. We concentrate on separation the properties of data in line with their scale diversity – in the distance, time, and nature and suggested a 3 step algorithm (scale-based technique) to convert Network–Unlike Entities into complex networks. The technique was applied for networkalization of landscape and land use maps representing Olkhon district, Irkutsk region, Baikal Lake territory, RF. It was found that the technique with its coarse-graining and area-like connecting conserves natural information inherent to the entities and imbeds accordingly scale-free and small world properties into output networks, thus making them really complex in their structure.

The activity of the design department (DD) is currently one of the most significant areas in the field of nuclear energy, the defense and rocket, and space industries. This area characterized by large volumes of used economic, technological, industrial and other resources. One of the tasks of the DD is to evaluate information assets (IA) and protect them from threats. The objectives of this article are to develop a method for assessing DD’s IA, as well as discussing the possibility of using this method in practice and the risks to which the DD is exposed unless special measures are taken to evaluate IA and threat analysis. Studies related to the assessment of the importance of information IA, the development of a threat model, and damage prediction investigated. The specificity of DD and processing of IA has been determined. In this paper, it is proposed to use the set-theoretic model for evaluating the IA of the DD that takes into account their structure, attributes, and life cycle. To assess the damage caused by the threat, it proposed to use the method of ALE. For the first time, a method for evaluating the IA of DD proposed. This method implemented in software. The software implementation successfully tested in an enterprise that includes the DD. The investigated problem studied quite recently. Therefore, there are open questions such as the classification of information assets of the DD and their categorization (confidentiality stamping), analysis of the life cycle of IA and threats, determination of the criticality level of the DD’s IA, assessment of damage from the realization of the threat. The prospect for the development of the research is the development of a threat model for information systems of the DD.

Solving the Inverse Kinematics of Robotic Arm Using Autoencoders

In the modern era, robotics is an attractive field for many researchers since robots are involved in many aspects of everyday life due to the conveniences and solutions that they provide in various daily difficulties. For this reason, the inverse kinematics of robotic arms is a challenging problem that seems more appealing to researchers as years pass by. In this paper, a novel approach to solve this problem is assessed, which is based on autoencoders. In our implementation the goal is not only to find one random (of the infinite solutions) of this problem, but to determine the one that minimizes both the position error between the actual and desired position of the end-effector of the robotic arm and the joint movement. For the training of the Neural Network of the autoencoder, four different types of the loss function and their corresponding results are examined. A robotic arm with three Degrees of Freedom is used for the evaluation of our implementation and the accurate results demonstrate the efficiency and effectiveness of our proposed method.

Method of Acquiring the Video Conference Using the Skill in Investigative Actions

The current law does not directly establish the possibility of remote investigative actions. However, it does not contain direct bans on the introduction of this progressive procedural form. Nevertheless, the practice of using information and communication technologies by an investigator in his work will inevitably lead to the need for detailed regulation of such improvements. The decision of the legislature on the full legal regulation of this problem is brewing. It is necessary to supplement the content of the training of the official’s persons, who will be in charge of criminal cases, at the expense of developing the skill to use the video conference system as needed during a number of investigative actions.

Development the Methodology of Urban Area Transport Coherence Assessment

The present paper analyzes modern approaches to assessing the balance of urban infrastructure. The definition of transport coherence is given. The developed methodology of urban area transport coherence assessment is described. The method of localized assessment of transport provision has been tested in cities of various shapes and sizes: positive results and limits of the method applicability are analyzed by example of Volgograd, St. Petersburg, Novosibirsk, Moscow, Elista, Astrakhan, Uryupinsk and Kamyshin. The features of application of technologies and data of OSRM and OSM are highlighted. Checking options for calculating the coefficient of coherence for cells was held. Verification of the results obtained by the four methods of calculating the average is performed by comparing the estimates of connectedness with the length of roads in the corresponding cells. For this, a method for calculating the local density of the road network has been proposed. It is proposed to use a transport plasmograph of the territory for a visual demonstration of the coherence of space and the possibility of assessing its main structural features. The paper describes the method of creating a plasmograph and provides examples of the analysis with its help of the territory of Novosibirsk and St. Petersburg. Conclusions are drawn about the possibilities of formalizing the infrastructure integrity of cities based on an analysis of their transport coherence and suggest promising areas for further research using the established methods for analyzing other types of infrastructure, as well as comparative analysis of cities.

Cryptographic Protection of Data Transmission Channel

Data transmission over the network is the most vulnerable stage of the information life cycle in the information system. The main way to protect data when transmitting over a communication channel is to hide its content. For this purpose, cryptographic means of information protection are used. Among the cryptographic means, encryption and digital signature are distinguished. There are different algorithms that allow performing encryption or digital signature. So which one is better? What algorithms should be used to make cryptographic protection the most effective? The study of the effectiveness of approaches to the construction of encryption algorithms is carried out. SP-network is recognized as more efficient than Feistel network. The study of the effectiveness of approaches to the construction of digital signature algorithms is carried out. The study took into account how the algorithm is used in conjunction with SP-network. Algorithm of the elliptic curve is recognized as the most efficient. As a result, the protocol of secure data transmission over the network is developed.

Use of Fuzzy Neural Networks for a Short Term Forecasting of Traffic Flow Performance

The method for a short term forecasting of the traffic in the urban road network and of the average vehicle speed is suggested. The author’s method is based on a regulatory approach to the calculation of the traffic capacity of the city road network. This method is completed with the methodology of forecasting the changes in the hourly traffic intensity. As the mathematical tool for the implementation of the forecasting methodology, the fuzzy neural networks are taken. It is suggested to make the forecast of short-term traffic intensity taking into account time of day, day of the week and season. On the basis of the data on the traffic capacity, the authors provide the relationships of an average speed change. The example of the calculation of transport flow performance is made in one of the motorways in the city of Volgograd.

Effective Quaternion and Octonion Cryptosystems and Their FPGA Implementation

An approach for effective hardware implementation of the proposed quaternion encryption algorithm (HW-R4) as well as modifications for known quaternion HW-QES and octonion HW-OES schemes are discussed. Instead of 3-D rotations as usually, 4-D transformations for encryption with quaternions and 8-D with octonions are suggested. Such size of transformation matrices increases the size of plaintext/ciphertext blocks and eliminates the need to calculate elements of rotation matrices. To speed up an encryption process the HW-R4, HW-QES, and HW-OES include mainly addition and shift operations with modular arithmetic. In our experiments, we used a product Intel (former Altera) OpenCL SDK (AOCL), which allows compiling OpenCL programs for FPGAs. The launch of the developed algorithms was carried out on two devices: the Intel Core i7 920 CPU and the Terasic DE5-Net FPGA (Stratix V). Experimental results show that the proposed algorithms and modifications are about 30–50% more effective in the encryption speed of signals than the original HW-QES/HW-OES. Additionally, HW-R4 is shown to be more effective in the encryption quality of images than the original QES. Our approach can also be used for robustness increasing when the Feistel network is added to the system.

Smart Contracts for Multi-agent Interaction of Regional Innovation Subjects

The main obstacle to effective interaction between innovation agents is high innovation transaction costs. The development of innovation requires the continuous interaction of participants at all stages of the innovation process, from idea to commercialization. The article discusses the creation of a safe and reliable way to support such interaction in regional innovation systems based on blockchain technology and smart contracts. This approach is recommended to exclude unfair and fraudulent actions on the part of participants. Another feature is the transfer of third-party functions to a smart contract to ensure safe communication. The smart contract will allow, on the one hand, to realize trustful and reliable relationships between the project participants themselves, and, on the other hand, between participants and stakeholders. The article discusses the possibilities of the Ethereum blockchain platform, with the help of which the main components of a smart contract were synthesized for concluding contracts for creating and introducing innovations, transferring intellectual property rights, using licenses, etc. The basis of the smart contract is a distributed registry of transactions and a database with descriptions of innovative objects.
