Part 4: Data Analytics and Artificial Intelligence
Older information and training as follows:
Early machine learning solutions, ML, were mainly black box generating scepticism over their applicability in critical situations in which one should be requested to just trust them. On the other hand, ethical aspects (on data and processes) are very relevant and a wrong assumption in taking data and/or setting up solutions may lead to biased results/suggestions, which may correspond discriminations and may lead to unforeseen costs. This was a real concern for former solutions and for the first generations of machine learning.
Snap4 technology is providing Big Data Analytic with Artificial Intelligence, AI, for leveraging businesses and solutions in producing reliable predictions, prescriptions, early warning, classifications, detections, suggestions, optimizations, and generation. In substance, Snap4 technologies lead to reduce costs and increase the efficiency of business and/or production processes. This implies to extract value from data, providing hints, prescriptions, suggestions, strategies, mitigations, and discovering solutions, information and implications never detected before, to learn and derive aspects of the phenomena up to now only observed and measured.
The applications can be in almost any domain of smart city and industry: mobility, health, energy, environment, waste, chemistry, manufactory, delivering, agriculture, boating, building, security, safety, etc.
The resulting advantages can be for final users, for decision-makers and for the city/companies. Examples can be:
- monitoring and controlling traffic, making prediction, traffic flow reconstruction, simulating and performing what-if analysis for strategic plan minimizing traffic congestions, reducing emissions, etc.
- Optimized estimation of traffic light plant taking into account public and private traffic, minimizing reducing: stops, travel time, and stops for tramways, waiting time, etc.
- Optimized traffic infrastructure viability in terms of roads, directions, lanes, etc., reducing traffic congestion, travel time, emissions, fuel consumption, etc.
- optimized positioning of bus stops, increasing the quality of transport experience and avoiding overcrowding, maximizing efficiency, minimizing costs, and decreasing the number of trips.
- parking predictions to reduce the social costs of looking for parking: reduction of fuel consumption, reduction of produced as NO2/CO2 for the whole community, etc.
- optimized routing based on present and predicted conditions, regarding traffic and maintenance works, for private drivers and city operators. Thus, for emergency services, reducing travel time, pollution, and the time required to reach the objective and perform services.
- understanding city usage conditions, and city users’ satisfactory and demanded services, etc. Increasing quality of services by solving the identified problems via collective intelligence.
- optimization of waste collection that reduces costs by minimizing the number of required trucks/trips and prevents waste from escaping bins through the use of predictive analytics. It is an advantage for the quality of life of city users and reduces administrative costs.
- predicting maintenance (for roads and services) to reduce intervention costs, operating costs associated with unexpected faults and services/productions interruptions, avoiding damages provoked by faults, etc. This also implies a reduction of the costs of production improving efficiency and resilience.
- sharing service prediction to reduce the time need to get/find a suitable sharing vehicle. Reduce costs and improve efficiency by means of sharing and pooling. Thus, increasing the quality of service also increases its effectiveness.
- assessing and predicting reputations of services, attractions, based on social media, with the purpose of enhancing the quality of services, reducing prices increase, and promoting alternative offers and solutions.
- early warning about possible landslides in the territory by computing predictions about landslides. Thus, reducing the risk for population, reducing the reaction time improving resilience of the territory.
- preparing the city and/or the industry to be more resilient to unexpected unknown events, natural or man-made disasters, by integrating simulations and ML/AI solutions enabling the what-if analysis in near real-time, increase resilience and capacity. Rapidly reacting to unanticipated, unforeseen events, so reducing the cost of recovery, which is the risk, and receiving advice to mitigate the risks and damages.
- Understanding the usage of city services to optimize energy and other resources needed for the expected serviceability and quality.
- Dialoguing with decision makers by using natural language, understanding and producing suggestion, generating solutions via Generative AI such as LLM.
- solving complex physical equations with Physically Informed Neural Networks, PINN, for Simulating fluid-dynamic flows in autoclaves and machineries, cost reduction, time reduction.
Snap4 AI/XAI solutions are capable to provide high precisions on predictions, classifications, prescriptions, suggestions and scenario generations and thus they can actually support decision makers as one of your best experts without humans’ bias. Snap4 AI/XAI solutions should be treated as a trusted expert to support decision makers to collaborate creating tailored solutions, and strategies to mitigate and solve short- and long-terms plan problems, as well as to support processes of What-If analysis, which were previously developed solely through simulations on the basis of hypothesis, and now the most effective solution can be directly generated by AI. Decision-makers can get suggestions shortening the boring activities and the AI can learn from the decision-makers’ objections improving progressively the AI capabilities and your preferences, taking into account additional aspects and elements. The recent solutions based on Large Language Models, LLM, may allow the decision maker to discuss with the expert in natural language. On the other hand, technical solutions still need to be generated by specialized AI rather than generalist LLM.
Extending these capabilities, the AI solution would allow entering in the loop with the community of users, and this would result in the production of new data for training (suggestions produced by the users to the AI, generative AI, as well as collective intelligence, from Participative solutions as Snap4City mobile Apps) which can be actually improve the AI precision and capability in modelling the phenomena and providing effective suggestions. Some of these approaches fit in the reinforced learning, transfer learning, fine tuning, and in the continuous learning techniques. Moreover, a relevant push has been provided by semantic reasoner tools (such as Km4City since 2013, in Snap4City), which started with the definition of ontologies and collecting data become actual expert systems which can be queries with semantic query language to perform inference and gest smart suggestions and results, neuro symbolic solutions. Examples are the graph neural network, graph data stores and the spatial, temporal and entities reasoners.
In recent years, AI has rapidly evolved and started to be used in complex systems and not only to produce direct predictions and prescriptions. Thus, decision-makers started to use the new solutions expecting to see them respecting the ethics (on data and processes), with aim of trusting them as their best experts. To this end, AI trustworthy, Data Ethics and AI Ethics approaches have been created by international and national bodies to guide AI developers in producing solutions which can actually serve the decision makers without prejudice and with correctness. Data Ethics refers to the aspects that may provoke a bias and ethical problems since the training; for example, training the AI with biased data, unbalanced distribution of cases, etc. Moreover, specific AI methodologies and solutions for Explainable Artificial Intelligence, XAI, are presently providing support in this direction since they are capable to explain the rationales behind the typical results provided (global explainable AI) and may provide specific description/rational for each result/suggestion provided (local explainable AI). XAI typically adds value to the suggested decisions producing hints and discovering implications and correlations never detected before by humans. They are a source of information to train the decision-makers about what has been discovered to be relevant for the AI. On the other hand, the decision makers can also provide to the AI continuous and lifelong training inputs for improving the capabilities of the AI. Thus, in Europe (April 2019) and in recently in other countries normative are going to set up regarding the AI Ethics, proving guidelines on training AI for Ethics, thus for AI trustworthy, Data Ethics and AI Ethics.

- As first step the present traffic and housing conditions have to be assed, then the progresses can be kept under control. The assessment can be performed by computing indicators. For example the 15 Min City index for serviceability at 15 minute distance by walking in the city and with different parameters in peripheral and rural areas, which includes an index for housing and slow and fast mobility. Relevant aspects are: (i) to assess the capability of the public transport to satisfy the demand, (ii) predicting traffic flow and reconstruction, (iii) making the what if analysis to be capable to assess how the traffic conditions would change due to changes in the road network, for example for restructuring, etc.

All the algorithms have worked continuously providing services to the users and also information to US: What they requested, What they visited, POI; where they passes: trajectories and OD matrix, Language, Routing, Clicking on services and icons, Engaging: responding, Searching.
Description of the main categories of Data Analysis provided.
- Discovery is provided by the Knowledge Base and it is attached to POI. This implies to create a geoindex.
- Discovery of public transport and multimodal routing are based on OSM, KB, and GTFS data
- The browsing of data on Public Transportation implies the analysis and processing of data collected as GTFS, in most cases, they are incomplete or they lack of cross linking that are reconstructed at the moment of ingestion that may happen once per day or once per season according to the updates released by the transportation companies. So that the Snap4City process has to continuously check the presence of updates on these data.
- Full test search implies a continuous full text indexing of all data entering into the platform
- Routing is computed on demand available from Mobile, ServiceMap and MicroApplications:
