Transfer Functions in Artificial Neural Networks - A Simulation-Based Tutorial

Artificial neural networks are based on computational units that resemble basic information processing properties of biological neurons in an abstract and simplified manner. Generally, these formal neurons model an input-output behaviour as it is also often used to characterize biological neurons. The neuron is treated as a black box; spatial extension and temporal dynamics present in biological neurons are most often neglected. Even though artificial neurons are simplified, they can show a variety of input-output relations, depending on the transfer functions they apply. This unit on transfer functions provides an overview of different transfer functions and offers a simulation that visualizes the input-output behaviour of an artificial neuron depending on the specific combination of transfer functions.

Oberflaechenverbesserung im 3D-Druck mittels hoeherer Aufloesung

Mit pulvergestützten 3D-Druckprozessen verbindet der Anwender bislang vor allem eine hohe Prozessgeschwindigkeiten bei mäßiger Genauigkeit und Oberflächenqualität. Dass das auch anders geht zeigt der vorliegende Artikel.
