Face recognition is an area that is still being researched and improved for various purposes such as attendance, population data collection, security systems and others. Two methods that are often used for face recognition applications are artificial intelligence methods, especially back-propagation neural networks (ANN) and learning vector quantization. Both of these techniques are directed learning techniques that are widely used to identify distinctive patterns, namely grouping patterns into groups of patterns, making them ideal for use in facial recognition applications. In this application, preprocessing of the input image includes the detection process of scaling, grayscale, edged with the sobel and threshold methods, carried out before the image is processed in ANN. Meanwhile, the ANN approach used to identify faces involves the Backpropagation method and the Learning Vector Quantization method. The findings of this analysis are a comparison of the backpropagation neural network method and quantization of the learning vectors of face recognition used to assess variations, limitations, strengths and optimal results of the two techniques for use in facial recognition systems.

This paper focuses on unlocking the creative potential of architecture students through an exploration of the Four C model of creativity. This model extends the traditional understanding of creativity and offers a comprehensive framework for fostering innovation in architecture. It introduces "mini-c" and "Pro-c" dimensions, highlighting creativity within the learning process and the attainment of professional expertise. Architecture demands a blend of technical skills and artistic expression for effective communication of ideas. However, nurturing creative thinking among architecture students faces challenges, including fear of experimentation and traditional teaching methods. To address these obstacles, the paper suggests integrating problem-based learning (PBL) and mind mapping techniques. PBL encourages collaboration and critical thinking, while mind mapping stimulates visual and associative thinking, aiding idea generation and organization. Additionally, the role of technology in architecture education is explored, emphasizing the benefits of mixed learning environments that enhance collaboration and creativity. Embracing technology readiness equips students with tools to tackle real-world challenges and create innovative designs. In conclusion, this paper underscores the importance of creative thinking in architectural design and its implications for the discipline's future. By adopting the Four C model, implementing PBL with mind mapping, and leveraging technology, educators can revolutionize architecture education, nurturing a new generation of architects prepared to shape the evolving world with imaginative and visionary designs.
