Prof. PhD. DrSc. A.Kaklauskas Member of the Research Council of Lithuania Member of the Lithuanian Academy of Science Vilnius Gediminas Technical University Sauletekio al. 11, LT-10223 Vilnius, Lithuania |
Abstract:The research described in this presentation integrated objective and subjective inhabitants evaluates of the city. These were conducted from two perspectives: that of an individual and that of the city. The development of the research design over the course of this research involved 11 stages. A research design using an integrated method with intelligent and biometrical technologies served as the basis for developing the Affect-Based City Video Analytics (ABC), the application used in this research. ABC supplies interested parties with the required data on the city and can assist them in evaluating and making decisions. The authors of this article attempt to integrate human emotions into the context of the maintenance and management of the city. One of the key aims is the indirect participation of inhabitants in maintenance and management procedures relating to the city. Consequently, ABC gathers and evaluates data on human affective attitudes, emotional and physiological states in the city and delivers these to city stakeholders. This is performed by applying neuro-matrices and a human-centered method for mining inhabitant affective attitudes, emotional and physiological states data from the city under analysis. The ROCK Video Neuroanalytics Database collects the following data:
- emotional states (happy, sad, angry, surprised, scared, disgusted or a neutral state), valence and arousal
- affective attitudes (boredom, interest and confusion)
- physiological states (average crowd facial temperature, crowd composition by gender and age groups, heart rate, breathing rate)
- weather conditions (air temperature, air humidity, average wind velocity, atmospheric pressure, apparent temperature)
- pollution (Magnetic Storm, SO2, KD2.5, KD10, NO2, CO, O3)
- Vilnius built environment and municipal districts data
With the help of ABC’s, emotional, affective and physiological maps of public spaces under analysis were created. Over the course of the H2020 ROCK project, ABC has accumulated over 250 million anonymized data points by remote means, and this number continues to grow. The strong and average correlations determined in this research (over 35,000) and data analysis by IBM SPSS software support the necessity to use variables such as affective attitudes, emotional and physiological states in the Affect-Based City Video Analytics. Finally, this presentation demonstrates the practical capabilities of ABC by employing case studies within Vilnius and Bologna cities as illustrations. The application of ABC proves that this system is valuable in conducting successful research and practical activities.

S2: Title: Second Order Data Mining of Financial Transaction Time-Series for Fraud Detection and Improved Customer Relationship Management
 |
Dr. Pawan Lingras |
Abstract:Clustering is an unsupervised learning technique. Since it does not require an expert categorization of patterns, it is one of the first data mining techniques applied to a new dataset. It helps a data scientist to identify patterns in a dataset. There is no correct solution for a clustering problem. The aim of clustering is to assign objects that are alike to the same cluster and ensure that different clusters are well separated from each other. This paper proposes a novel technique for time-series data mining that uses multiple and sequential application of a number of data mining techniques to gain insights into financial transaction dataset that can be used for fraud detection and other behavioral aspects of a customer.
An important first step in creating unsupervised profiles of a customer are finding an appropriate representation. Time-series of financial transactions offer us multiple alternatives:
Spending distribution from month to month (Jan, Feb, …, Nov, Dec)
Spending distribution from day to day in a week (Monday, Tuesday, …, Saturday, Sunday)
Spending distribution during a day (morning, afternoon, evening, night)
Spending distribution among various categories (grocery, household, restaurants)
Geographical distribution of spending:
Spending in City of Residence
Spending in Province of Residence
Spending in Country of Residence
Online spending
Histogram of spending based on distance of vendor from the residence
Each one of these representations describe different behavioral aspects of a customer. To generate meaningful insights from this first order of data mining, the project proposes a second order data mining. The five set of profiles can be used as attributes in a derived dataset. The dataset can then be further analyzed using various data mining techniques including business intelligence, association mining, supervised learning (classification), and second order unsupervised learning (clustering).
Business intelligence will help us compare summary statistics of different profiles against the population. For example, "value conscious" customers spend a greater percentage of their money in groceries than average.
The association mining will provide rules such as:
- Those who spend more in summer tend to spend more on weekends
- Those who do not spend in summer tend to spend more on hotels in February
The supervised learning will use known incidences of frauds and anomalous behavior in the financial transaction data and create models that predict the chances of frauds and anomalies based on the profiles of the customers.
The second order unsupervised learning will also help us understand the correlations between different profiles. For example, "summer spenders" tend to be "non-local spenders".
The resulting insights will help us identify:
Unusual spending pattern such as a client who never spends at night having a large transaction
Building an inference system that uses the association rules that make up normal behavior. Any transaction that fall outside normal behavior can be easily assigned a probability of potential fraud
Additional insights may include knowledge such as:
The customer only uses this card for restaurants and hotels. That means, she must be using a different card for other spending needs
A customer with this profile should be spending more on travel. The low or absence of travel spending on this card may suggest a use of another card
These insights can be used to encourage customer to shift spending from other cards to this card.

S3: Title: Anomaly Detection for Clusters of Data
 |
Prof. Dr. Stephen Huang, Department of Computer Science, University of Houston, USA |
Abstract: Intrusion detection systems attempts to detect attacks by comparing data to predefined malicious activities (signature-based IDS) or to a model or profile of normal behavior (anomaly-Based IDS). These profile-based approaches can also be applied to detections anomaly of clusters of data, such as blood cells, other than network intrusions. However, most of the current detections assume that the data set consists of (multi-attribute) data points in a multi-dimensional space. Sometimes each individual data point does not carry much information. It is the collection of data that contains inherited information. This talk will show two examples of how to detect the behavior of clusters of data. In detecting intruders at the end of stepping-stone chain, it is common to study gaps between packets. But each individual gap means nothing. It is the collection of the gap that characterize the chain. In the case of computational pathology, we have a very similar issue. A single cell in the blood sample tells us nothing while a collection of cells (size, shape, etc.) that can help us in identifying cancer patients. This talk will discuss the issues involved in finding solutions for this types of problems.

S4: Title: Edge Detection method using Soft Computing techniques applied to Pattern Recognition
 |
Prof. Patricia Melin, Ph.D., D.Sc. Tijuana Institute of Technology, Tijuana, Mexico |
Abstract: Edge detection is a fundamental part in many computer vision and image processing applications, such as pattern recognition, medical image processing, object recognition, and motion analysis. Edge detection process is widely used in pattern recognition and computer vision systems because it is helpful in obtaining satisfactory results when applied in the preprocessing phase. The process of finding the edges is not easy, especially if the image is blurry or distorted by noise; these phenomena frequently occurs when the image is captured by any acquisition hardware, factors like the distance, quality, and resolution of cameras, environment, and illumination variation tend to produce images with ambiguous or incomplete data. The issue of determining what is an image edge and what is not becomes more critical by the fact that edges are partially distorted or hidden. In order to solve this issue for image edge detection, in recent years, various approaches that involve soft computing methods have been proposed, including the principles of fuzzy set theory, which is one of the main topics in this Talk. In the past few decades most research has concentrated on designing edge detector algorithms for grayscale images; however, color image processing applications have recently been receiving increasing attention because color images provide more information about the objects in a scene than grayscale images and this information can be used to improve the performance of image processing systems. Edge detection in color images is computationally more complex than in grayscale images, but there are many advantages to using color images. For example, the increase in the amount of information can lead to more accurate object location and the possibility of processing images that are more complex. Fuzzy techniques for edge detection have gained importance because they offer a good alternative to enhance the accuracy in the edge detection process. In this talk we will focus in various edge detection techniques using Type 1 fuzzy logic, interval type-2 fuzzy logic and General type-2 fuzzy logic applied in gray scale and color images and how to use in pattern recognition.

S5: Title: Optimization of Type-2 Fuzzy Systems: Theory and Applications
 |
Prof. Oscar Castillo, Ph.D., D.Sc. Tijuana, Institute of Technology Tijuana, Mexico |
Abstract: Type-2 fuzzy systems are powerful intelligent models based on the theory of fuzzy sets, originally proposed by Prof. Zadeh. Most real-world applications up to now are based on type-1 fuzzy systems, which are built based on the original (type-1) fuzzy sets that extend the concept of classical sets. Type-2 fuzzy sets extend type-1 fuzzy sets by allowing the membership to be fuzzy, in this way allowing a higher level of uncertainty management. Even with the current successful applications of type-1 fuzzy systems, now several papers have shown that type-2 is able to outperform type-1 in control, pattern recognition, manufacturing and other areas. The key challenge in dealing with type-2 fuzzy models is that their design has a higher level of complexity, and in this regard the use of bio-inspired optimization techniques is of great help in finding the optimal structure and parameters of the type-2 fuzzy systems for particular applications, like in control, robotics, manufacturing and others. Methodologies for designing type-2 fuzzy systems using bio-inspired optimization in different areas of application are presented as illustration. In particular, we will cover Bee Colony Optimization, Particle Swarm Optimization, Gravitational Search and similar approaches to the optimization of fuzzy systems in control applications, robotics and pattern recognition. Finally, we will also consider using fuzzy logic for enhancing the performance of metaheuristics, where also good results have been achieved.
