Discrete Indoor Three Dimensional Localization System Based on Neural Networks Using Visible Light Communication

2018
PMCID: 5948482
PMID: 29601525
DOI: 10.3390/s18041040

[…] s the estimated output and y is the target output used to train the system. (4)J(y^,y)=f(w,b) There are different algorithms to train a neural network, but in this work a Matlab implementation of the Scaled Conjugate Gradient algorithm was used []. During the training process, the weights are adapted in order to minimize the cost function. The training phase can end when the cost function reaches […]

Statistical and Machine Learning forecasting methods: Concerns and ways forward

2018
PLoS One
PMCID: 5870978
PMID: 29584784
DOI: 10.1371/journal.pone.0194889

[…] ractical guidelines suggested by [] aimed at decreasing the computational time needed for constructing the NN model (the number of the hidden layers used is typically of secondary importance []). The Scaled Conjugate Gradient method [] is then used instead of Standard Backpropagation for estimating the optimal weights. The method, which is an alternative of the famous Levenberg-Marquardt algorithm […]

Classification of Suicide Attempts through a Machine Learning Algorithm Based on Multiple Systemic Psychiatric Scales

2017
PMCID: 5632514
PMID: 29038651
DOI: 10.3389/fpsyt.2017.00192

[…] erial). Two parameters (presence or absence of a suicide attempts) were set as the output. Data were randomly divided into three sets (70% for training, 15% for validation, and 15% for test), and the scaled conjugate gradient method was used for training (, ). Training automatically stopped when validation reached the minimum cross entropy, and the performance of each variable was measured by the […]

Unsupervised learning of temporal features for word categorization in a spiking neural network model of the auditory brain

2017
PLoS One
PMCID: 5552261
PMID: 28797034
DOI: 10.1371/journal.pone.0180174

[…] ss of different auditory brain models and encoding schemes under investigation. The MLPs had hidden layer neurons with hyperbolic tangent transfer functions. They were trained until convergence using scaled conjugate gradient descent [] and a cross-entropy loss function. Once the MLPs were trained, their classification outputs were used to fill the confusion matrices used in the information analys […]
