In this paper, the vision-based hand movement recognition problem is formulated for universe of discourse Brazilian Sign Language. order to analyze specific domain we have used artificial neural networks models based on distance, including neural-fuzzy models. The experiments explored here show usefulness these extract helpful knowledge about classes movements and support project adaptative recognizer modules Libras-oriented computational tools. Using architectures - Self Organizing Maps...

This study systematically assesses the process mining scenario from 2005 to 2014. The analysis of 705 papers evidenced 'discovery' (71%) as main type addressed and 'categorical prediction' (25%) task solved. most applied traditional technique is 'graph structure-based' ones (38%). Specifically concerning computational intelligence machine learning techniques, we concluded that little relevance has been given them. are 'evolutionary computation' (9%) 'decision tree' (6%), respectively....

Although large language models (LLMs) demonstrate strong text generation capabilities, they struggle in scenarios requiring access to structured knowledge bases or specific documents, limiting their effectiveness knowledge-intensive tasks. To address this limitation, retrieval-augmented (RAG) have been developed, enabling generative incorporate relevant document fragments into inputs. In paper, we design and evaluate a RAG-based virtual assistant specifically tailored for the University of...

Gesture analysis has been widely used for developing new methods of human-computer interaction. The advancement reached in the gesture area is also motivating its application to automate tasks related discourse analysis, such as phases segmentation task. In this paper, we present an initiative that aims at segmenting gestures, especially considering "units" -- larger grain involved segmentation. Thereunto, have captured gestures using a Xbox Kinect™ device, modeled problem classification...

A smart toy is defined as a device consisting of physical component that connects to one or more computing services facilitate gameplay in the cloud through networking and sensory technologies enhance functionality traditional toy. this context can be effectively considered an Internet Things (IoT) with Artificial Intelligence (AI) which provide Augmented Reality (AR) experiences users. In paper, first assumption children do not understand concept privacy know how protect themselves online,...

Purpose – Process mining is a research area used to discover, monitor and improve real business processes by extracting knowledge from event logs available in process-aware information systems. The purpose of this paper evaluate the application artificial neural networks (ANNs) support vector machines (SVMs) data tasks process context. goal was understand how these computational intelligence techniques are currently being applied mining. Design/methodology/approach authors conducted...

In the information systems development, software engineers seek to improve systems’ functionality and usability, which may require a review of their requirements. Considering teaching-learning process scenario, guaranteeing such goals demands comply with pedagogical rules satisfy student desires needs. This paper reports on an experiment in requirements refinement for Learning Management System, involving system’s users through application Design Thinking methodology. is human-centered set...

In several countries, deaf communities adopt the sign language as their official and natural language. This fact inserts a new field for software application development that can improve dissemination social inclusion of people. Alphabetic character-based applications, like games educational softwares, be adapted to run fingerspelling-based in which inputs are signs (static images or videos) rather than letters (typed letters). this paper, we present Pattern Recognition Module, implemented...

Currently the demand for development of more precise and reliable methods person identification have received attention from academic community industry, with Biometrics being one these new approaches. The term 'Biometrics' is used to refer techniques based on physical or behavioural characteristics. As biometric recognition becomes increasingly popular, fear circumvention, obfuscation replay attacks a rising concern. Since traditional modalities (face, iris fingerprint) are not able supply...

Business processes are subject to changes over time due the need for adaptation and flexibility a complex environment. Detecting drift as soon possible identifying process elements involved, lead much better understanding of behavior, which can be competitive edge businesses. However, most existing approaches focus on each these two tasks separately. Isolated do not always have interfaces between them that allow you combine solutions effectively corresponding task. In such cases, using...
