    Development of a high-accuracy multi-sensor, multi-target coordinate metrology system using frequency scanning interferometry and multilateration (Invited Paper) Paper Time: AM - PM Author(s). Dynamic range: Has everything to do with the optical properties of the sensor. Dynamic range ideally is limited by the shot noise of the sensor which tracks as the \${N}^\frac{1}{2}\$ with N being the number of photons. SNR is also important as is it the ratio of SEE to NEE - Saturation equivalent exposure to noise equivalent exposure. Genetic Algorithms are powerful tools, which when set upon a solution space will search for the optimal answer. These algorithms though have some associated problems, which are inherent to the method such as pre-mature convergence and lack of population diversity. These problems can be controlled with changes to certain parameters such as crossover, selection, and : Ferat Sahin, Giuseppe Abbate. Abstract. The field of optomechatronics provides synergistic effects of optics, mechanics and electronics for efficient sensor development. Optical sensors for the measurement of mechanical quantities, equipped with appropriate electronic signal (pre)processing means have a wide range of applications, from surface testing, stress monitoring, thin film analysis to .

    Rosenblatt first suggested this idea in , but he used perceptrons. However, their non-differentiable output function led to an inefficient and weak learning algorithm. The idea that eventually led to a breakthrough was the use of continuous output functions and gradient descent. Septem Neural Networks Lecture 7: Perceptron.
