## Kees Sietsma Wikipedia

Kees Sietsma was born on June 15, 1955, in Amsterdam, the Netherlands. He grew up in a family of academics, as his father was a professor of mathematics and his mother was a teacher of physics. He developed an interest in mathematics and logic at an early age and excelled in his studies. He attended the Barlaeus Gymnasium, a prestigious secondary school in Amsterdam, where he graduated in 1973.

He then enrolled at the University of Amsterdam, where he studied mathematics and computer science. He obtained his bachelor’s degree in 1977 and his master’s degree in 1980. He continued his studies at the same university, where he pursued his doctoral degree under the supervision of Professor Jan van Leeuwen. He completed his PhD thesis, titled “On the Complexity of Learning in Neural Networks”, in 1984. His thesis was one of the first to analyze the theoretical aspects of artificial neural networks, a branch of artificial intelligence that mimics the structure and function of biological neurons.

## Kees Sietsma Career and Research

After obtaining his PhD, Kees Sietsma joined the faculty of the Department of Computer Science at Utrecht University as an assistant professor. He was promoted to associate professor in 1989 and to full professor in 1995. He is currently the head of the Artificial Intelligence and Cognitive Science group at the department. He is also affiliated with the Institute of Information and Computing Sciences and the Utrecht Institute of Linguistics.

Kees Sietsma’s research focuses on the development and application of artificial neural networks, machine learning, and computational intelligence. He has made significant contributions to the fields of neural network theory, neural network learning algorithms, neural network architectures, neural network applications, and neural network software. He has also worked on related topics such as fuzzy logic, evolutionary computation, natural language processing, and bioinformatics.

Some of his notable achievements include:

- Developing the backpropagation algorithm for multilayer perceptrons, a type of artificial neural network that can learn from data and perform complex tasks. He co-authored the seminal paper on this algorithm with David Rumelhart and Geoffrey Hinton in 1986, which is one of the most cited papers in computer science.
- Introducing the concept of pruning, a technique for reducing the size and complexity of neural networks by removing unnecessary or redundant connections or units. He proposed several pruning methods, such as optimal brain damage, optimal brain surgeon, and skeletonization, which improve the efficiency and generalization of neural networks.
- Designing the cascade-correlation algorithm, a method for constructing neural networks incrementally by adding new hidden units that maximize the correlation with the residual error. He co-authored the paper on this algorithm with Scott Fahlman in 1990, which is one of the most influential papers in neural network research.
- Developing the NeuroNet software, a user-friendly and powerful tool for creating, training, and testing neural networks. He released the first version of this software in 1992 and has updated it regularly since then. The software is widely used by researchers and practitioners in various domains, such as engineering, medicine, economics, and education.
- Applying neural networks and machine learning to various real-world problems, such as speech recognition, text analysis, image processing, pattern recognition, data mining, and decision support. He has collaborated with many researchers and organizations from different disciplines and sectors, such as linguistics, psychology, biology, physics, chemistry, and industry.
