Consider a problem with 2 feature variables, x = [x1 x2] where -5.0 < x < 5.0, and -5.0 < x < 5.0. Assume a true label function has the following form known as by-linear function: y(x) = cocx1 + 2x2 + C3x1 x2 where c;(i = 0, 1, 2, 3) are given constants of real scalar numbers. In the numerical study, use: co 2.8, c 3.1. ey 1.5, cy=0.8 = 1. Construct a prediction function with proper set of learning parameters, that is capable of predicting the true label function. Define a loss function, and use it to design a possible procedure that is capable of leading to a correct prediction analytically. 2. Use a dataset with 4 data points. Define a proper loss function and derive formulas that leads to a unique solution in predicting the true label function analytically. Discuss about the conditions for the uniqueness. 3. Create quality dataset each with sufficient number of numerical data points with the numerical label values, using the given true label function. Define a proper loss function and a (Python) code to make predictions. Show that the constants given in Eq.(???) are reproduced from the dataset created by your code. Test your code thoroughly, provide proper conditions on safe-use of your code, and list also possible issues when using your code. 4. Create poor dataset that has deficiency in the data matrix. Repeat task 3 and discuss about the possible problems, find a solution to overcome it, and tes you solution in a code. 5. Discuss possible issues if the features space dimension is very high, say p = 10,000. Consider a problem with 2 feature variables, x = [x1 x2] where -5.0 < x < 5.0, and -5.0 < x < 5.0.
