activation functions (ReLU) are in this network, before the final output? (Experimental) In a neural network with two internal layers and a total of 10 neurons, should you put more of those neurons in layer 1 or layer 2? 10 activation functions (ReLU) are in this network, before the final output?

A deep neural network has multiple layers with non-linear activation functions (e.g., ReLU) in between each layer, which allows it to learn a complex non-linear function. Suppose instead we had a deep neural network without any non- linear activation functions. Concisely describe what effect this would have on the network. (Hint: can it still be considered a deep network?)
1. Consider a neural network, which contains one hidden layer and an output layer with one output unit. Let the hidden units have negative sigmoid as the activation function, which is formulated as 1 n(v) 1 + exp(-1) and the output unit has a linear activation function in which the output is equal to the activation input). (a) Show that the derivative of the negative sigmoid obeys the following relation dn(v) dv = n(v)(1 + n(v)) (b) Let the cost...
1. Hopfield Neural Network with 4 Neurons are used to memorize four states (1,-1, 1,-1) and (1, 1,, 1). If we consider that the output of each neuron is fed back into the inputs of all other neurons except itself in the first system and fed back into the inputs of all other neurons with itself at the second system.

4.7. Consider a two-layer feedforward ANN with two inputs a and b, one hidden unit c, and one output unit d. This network has five weights (wca, Wcb, Wco, Wse, Wao). where wro represents the threshold weight for unit x. Initialize these weights to the values (.1,.1,.1,.1,.1), then give their values after each of the first two training iterations of the BACKPROPAGATION algorithm. Assume learning rte '-.3, momentum α-: 0.9, incremental weight updates, and the following training examples: 0 1...
Network Security Class Questions Which statement best describe the term “Network Enumeration”? (NOT SURE) Network Enumeration means by hackers scout target leverage techniques over the phone to make the target reveal critical information such as SSN, credit information Network Enumeration means “case the joint” this is another form of intelligence gathering Enumeration identifies and poorly protected resource shares are exploited to gain access Network Enumeration describe the motivation of a hacker and the level of ingenuity of the hackers All...
4. (15) You designed a polymer based hydrogel scaffold which can direct neural stem cells (NSCs) to differentiate into neurons in a linear grid. To check whether the cells differentiated, you used immunofluorescence to stain the cells for neural markers MAP-2 and DCX and NSC marker Sox2. a) What data do you expect to see from your immunofluorescence experiment if the NSCs had differentiated? b) Is this experiment sufficient? What other experiments should we do to confirm? (No need to...
