What is the main objective in ML (Machine Learning) in Data Science?

Why do you think Klay uses “you” in the following passage?  If I were to shoot you on either side of your heart, one shot . . . and then another, you’d have twopunctured lungs, two sucking chest wounds. Now you’re good and fucked. But you’ll still be alivelong enough to feel your lungs fill up with blood. If I shoot you there with the shots coming fast, it’s no problem. The ripples tear up your heart andlungs and you don’t do the death rattle, you just die. There’s shock, but no pain. I pulled thetrigger, felt the recoil, and focused on the sights, not on Vicar, three times. Two bullets torethrough his chest, one through his skull, and the bullets came fast, too fast to feel. That’s how itshould be done, each shot coming quick after the last so you can’t even try to recover, which iswhen it hurts. What rhetorical (logos, pathos, ethos) effect does his usage of “you” have on the reader and his argument? 

Aside from creating decision trees, when would you use information gain?

Rhetorical analysis involves

Literature can be seen as a ___________, mirror, and. __________________. 

If students need to know who their advisor is, how do they find out?

What element is being oxidized in the following redox reaction? 6 H+ + 2 MnO4⁻+ 5 H2C2O4 → 2 Mn2+ + 8 H2O + 10 CO2

A ligand that can donate three pairs of electrons to the central metal ion is classified as:

In Data Science and Machine Learning, which do we usually use: dummies or one-hot encoding?

Using the following metals and their standard potentials, organize your metals starting with the strongest oxidizing agent and finishing with the weakest.   Sn2+(aq) + 2 e⁻ → Sn(s)       E° = -0.14 V Ag⁺(aq) +  e⁻  → Ag(s)          E° = +0.80 V Mg2+(aq) + 2 e⁻ → Mg(s)    E° = -2.38 V Cu2+(aq) + 2 e⁻  → Cu(s)     E° = +0.34 V
