A neural network is built for a dataset that has binary target value (0 or 1). The cost function used for these applications is 'cross entropy' which is defined as follows. Cost Function = -( (target-log(compValue) + (1 − target) + log(1-compValue))) Compute the cost function values using TensorFlow for the following cases. Cost Function 1 2 3 4 5 1 2 3 4 5 Observed output Target 0 0 0 0 0 Observed output Target 1 1 1 1 1 Computed Value 0.95 0.8 0.6 0.4 0.1 Computed Output 0.95 0.8 0.6 0.4 0.1 Answer: Target= 0 Computed Value = 0.95 Cost Function= Computed Value = 0.8 Cost Function = Computed Value = 0.6 Cost Function= Computed Value = 0.4 Cost Function= Computed Value = 0.1 Cost Function= ? ?
