- We would like to learn a model to predict whether a monster is scary or not (S). We identify four features for this purpose: Number of eyes (N), Color of eyes (C), Height (H), and Odor (O).

Suppose a researcher wants to know if there is a significant difference in aptitude scores based on a recruits’ fitness level. Recruits are ranked on a scale of 1 – 3 for fitness (1 = lowest fitness category, 3 = highest fitness category). Using “ApScore” as your dependent variable and “FitGroup” as your independent variable, conduct a One-Way, Between Subjects, ANOVA, at α = 0.05, to see if there is a significant difference on the aptitude test between fitness groups.

With likelihood 12, he leaves his present club, then, at that point, makes another club himself and goes along with it. There is just a single understudy (himself) in the new club he makes. With likelihood 12, he doesn't make new clubs. For this situation, he changes his club to another one (perhaps a similar club he is in right now) with likelihood relative to the number of understudies in it. Officially, assume there are k clubs and there are bi understudies in the I-th club for 1≤i≤k (before the understudy blows up). He leaves his present club, and afterward joins the I-th club with likelihood canister. We note that when a club becomes unfilled, understudies won't ever go along with this is on the grounds that any understudy who blows up will get a vacant club together with likelihood 0 as per the above assertion.

- 1 Functional Dependencies The Armstrong Axioms are sound, complete, and independent. They are not the only options for reasoning about functional dependencies, however. For example, we have seen the Union and Decomposition rules. Next, we will explorer some alternative options: Problem 1. Consider the following inference rules: 1. If X Y and WY→ Z, then XWZ. 2. If XYZ and Z WV, then X→→→ YZV. 3. If X Y and Z CY, then X →→ Z. P1.1. Prove that the first inference rule is sound using only the Armstrong Axioms. P1.2. Prove that the second inference rule is sound directly from the definition of functional dependencies (without using any inference rules). P1.3. Prove that the third inference rule is sound. P1.4. Are these inference rules complete? If so, then prove why. Otherwise, show why not. HINT: You may assume that the Armstrong Axioms are complete. P1.5. Are these inference rules independent? If so, then show why. Otherwise, show why not. Problem 2. Consider the following two inference…arrow_forwardA robot who updates its beliefs using Bayesian reasoning has just obtained measurement z from pointing its sensor array at a door. It would like to determine whether the door is open (P(open|z)) before driving forward. The prior probability of P (open) = 0.3 and P (closed) = 0.7 Your sensor model indicates that the likelihood of seeing that observation is P(z|open) = 0.6 and P (z|closed) = 0.3. Calculate the posterior P (open|z).arrow_forwardSubject: Machine Learning A dataset showing the decisions about presence of Heart Disease (HD) based on four attributes (Age, Blood pressure, Cholesterol and Heart rate) is listed in the following table: Age BP CH HR HD Old Low Low Medium No Very old Low Medium Low Yes Old Medium Medium Medium No Old Low Low Low Yes Mild Low Low Medium Yes Very old High Medium Low Yes Very old Medium Medium Low Yes Mild Medium Very high Low Yes Old Low Medium Medium No Very old Medium Very high Medium No Very old Medium Low Medium No Mild Low Medium Medium No Mild Low Medium Medium No Compute the entropy for this data set.
