a) Define Prediction Bias, Variance, and Mean Squared Error (MSE). (b) Discuss how these terms are related.

When and why are proportional, binomial, and Poisson regression models used?

given the observed data (obsX,obsY), learning rate (alpha), error change threshold, and delta from the huber loss model,write a  function returns theta0 and theta1 that minimizes the error. Use pseudo huber loss function

Solve the following. You can write your answers on paper and submit them, or use whatever online tools allow you to submit a PDF. Everyone needs to submit their own work. 1. Determine the logic function and the truth table for Figure 1. X1 X3 X2 -f Figure 1: Stylized System Diagram for Question 1 2. Given the logic function, f (x1, x2, x3) = x1 • x3 + (x2 · x3)/ write the truth table and draw the logic network. Compute the cost of the network. Submit your answer online. If you wrote your answers on paper and don't have access to a document scanner, Adobe Scan from Google Play and the Apple Store is one option (there are many other scanning apps that use your phone - feel free to suggest others on the Slack channel that you've found useful). You can use this to create a single PDF document of your work and then submit to Canvas.
