SWE $459$ SAMPLE QUESTIONS

$1.$ Define an Artificial Neuron Network $($ANN$)$ model as; $4$ input, $2$ hidden layer with $4$ neurons each and $1$ outputs. The weight coefficients will be chosen randomly $\backslash ([0,1]\backslash ).$ Apply activation functions given below;

$($a$)$ Linear

$($b$)$ Threshold

$($c$)$ Sigmoid non$-$linear

Then curve outputs of the ANN structure.

$2.$ Explain wavelet approach and related main wavelet equation. Draw wavelet model with the level of $\backslash (\backslash$mathrm$\{$cA$\}\_\{4\}\backslash )$ and $\backslash (\backslash$mathrm$\{$cD$\}\_\{3\}\backslash )$ at the transmitter and related receiver block.

$3.($a$)$ For $\backslash (8\backslash$times $8\backslash )$ matrix input matrix with randomly chosen elements in the range of $[0,1].$

$($a$)$Apply lowpass filtering then down sampling output.

$($b$)$ Apply high pass filtering then down sampling
