- Computer Science A way to avoid overfitting in Deep Neural Networks is to add an additional term R to the loss function L (for example L can be the cross entropy loss) as follows: L(w) + λR(w). (1) You know that one choice for R is the L2 norm, i.e. R(w) = ||w||2 2 . One friend of yours from the School of Maths told you however that there’s no need to use squares (i.e. powers of two) and that you can achieve the same effect by using absolute values, i.e. the L1 norm: R(w) = ||w||1. Would you agree with him? i.e. is the use of the L2 norm equivalent to using the L1 norm for regularization purposes? Justify your answerTelemedicine is the ability to provide medical assistance from a distance using telecommunication. For this example, imagine that a platoon of soldiers might be out in the battlefield. While a medic might be with them, he/she cannot constantly monitor each soldier’s vital signs, but if various sensors were sewn into soldier uniforms, vital statistics could be monitored from a distance by a doctor at headquarters. That doctor may be able to identify a medical problem for one of the soldiers and relay that information and instructions for care back to a medic in the area. The doctor at headquarters should be able to select a given soldier and see that soldier’s vital signs on a portable computer device (e.g., iPad). Perhaps the medic in the field might even have a video camera so that the doctor may be able to view a wound. Design the interface that the HQ doctor would see. Using the display design principles design an interface mockup using graphics, photos, and/or text to show what…plot these function in single graph f(x1) : 3x^3-26x+10 with - symbol with blue color f(x2) : 9x^2-26 with - symbol with red color f(x3) = 18x with . symbol with black color x = -2 to 4 with increment of 0.01
