Neural network and random forest are models of machine intelligence. Which one is used in machine vision?
Homework Answers
Question:---------- Neural network and random forest are models of machine intelligence. Which one is used in machine vision?
Answer:------------ Neural network, The Neural Network is a network of connected neurons. The neurons cannot operate without other neurons - they are connected. Usually, they are grouped in layers and process data in each layer and pass forward to next layers. The last layer of neurons is making decisions.

Exercise Optimization in neural network Consider a very simple neural network with two input values, one output value, and a single neuron with sigmoid activation. Each input to the neuron has an associated weight, and the neuron has a bias. So the network represents functions of the form o(W1X1 + W222 + b). We train the neural network using least squares loss on a single piece of training data ((1, -1),0). Initially all weights and biases are set to 1....

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...

The general neural network methodology is often described as a "black box" methodology. In a practical sense, which of the following is the most negative effect of this? A. The predictions from neural nets are often accurate, often more accurate than from other methods, but it is practically impossible to untangle the effects of the individual explanatory variables on the dependent variable. B. The detailed steps of the algorithm are totally random, even though they often produce accurate predictions. C....
