Igor Aleksander: A Pioneer in Neural Systems Engineering
The evolution of artificial intelligence owes much to the early architects of neural modelling. Among these figures is Igor Aleksander, a distinguished academic and engineer whose career spanned several decades and prestigious institutions. His work bridged the gap between biological systems and computational engineering, focusing on how machines might emulate the complex processes of the human mind.
Academic Journey and Professional Career
Aleksander's educational path was international, beginning with studies in Italy and culminating in a degree from the University of the Witwatersrand in South Africa. He arrived in the United Kingdom in the late 1950s with the initial goal of pursuing research under Colin Cherry. However, his professional trajectory shifted toward industry and academia when he joined Standard Telephones and Cables.
He later transitioned to Queen Mary College, where he earned his PhD and began his teaching career as a lecturer in 1961. Over the following decades, Aleksander held several senior academic positions, including a role as a reader in Electronics at the University of Kent in 1968 and a professorship at Brunel University in 1974.
In 1984, he joined Imperial College London as the Professor of the Management of Information Technology. His leadership at the institution grew significantly; from 1988 until his retirement in 2002, he served as the Head of Electrical Engineering and the Gabor Professor of Neural Systems Engineering. His contributions were recognized in 1988 when he was elected a Fellow of the Royal Academy of Engineering, and he later served as the Pro-rector of External Relations at Imperial College in 1997.
Contributions to Neural Networks and AI
Aleksander's primary research focused on the modelling capability of artificial neural networks—computational systems inspired by the biological neural networks that constitute animal brains. He sought to create neuromodels (mathematical representations of neural activity) to understand various complex systems.
His research areas included:
- The visual system in primates.
- The visuo-verbal system in humans.
- The impact of anaesthetics on human awareness.
- The theoretical framework of artificial consciousness.
The WISARD System
One of Aleksander's most tangible achievements was the engineering of the WISARD (Wilkie Stonham Aleksander's Recognition Device). Developed alongside co-inventors Bruce Wilkie and John Stonham, WISARD was one of the first standalone neural pattern recognition systems.
Originally a prototype at Brunel University, the system was commercially developed and marketed in 1984 by Computer Recognition Systems in Wokingham under the trade name 'CRS WISARD'. While further documentation of the system's development is sparse, its historical significance is preserved through the Winton Gallery at the British Science Museum.
