Improving Neural Network Efficiency Using Piecewise Linear Approximation of Activation Functions
Proceedings of the International Florida Artificial Intelligence Research Society ConferenceActivation functions play a pivotal role in Neural Networks by enabling the modeling of complex non-linear relationships within data. However, the computational cost associated with certain activation functions, such as the hyperbolic tangent (tanh) and

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Proliferation of non-linear excitations in the piecewise-linear perceptron
SciPost Physics, 2021 We investigate the properties of local minima of the energy landscape of a continuous non-convex optimization problem, the spherical perceptron with piecewise linear cost function and show that they are critical, marginally stable and displaying a set of

Parameter-dependent PWQ Lyapunov function stability criteria for uncertain piecewise linear systems [PDF]
Modeling, Identification and Control, 2018 The calculation of piecewise quadratic (PWQ) Lyapunov functions is addressed in view of stability analysis of uncertain piecewise linear dynamics. As main contribution, the linear matrix inequality (LMI) approach proposed in (Johansson and Rantzer, 1998)

Stability Analysis of Switched Linear Singular Systems with Unstable and Stable Modes
Entropy, 2023 In this paper, stability is studied for a class of switched singular systems containing both stable and unstable modes. By introducing a time-varying piecewise Lyapunov function (TVPLF) and a mode-dependent average dwell time (ADT) switching rule, the ...
