2. Some times, feature normalization is not feasible in case of categorical variables
3. Feature normalization always helps when we use Gaussian kernel in SVM

User level threads are threads that are visible to the programmer and are unknown to the kernel. The operating system kernel supports and manages kernel level threads. Three different types of models relate user and kernel level threads. Which of the following statements is/are true ? (a) (i) The Many - to - one model maps many user threads to one kernel thread (ii) The one - to - one model maps one user thread to one kernel thread (iii) The many - to - many model maps many user threads to smaller or equal kernel threads (b) (i) Many - to - one model maps many kernel threads to one user thread (ii) One - to - one model maps one kernel thread to one user thread (iii) Many - to- many model maps many kernel threads to smaller or equal user threads

A

(a) is true; (b) is false

B

(a) is false; (b) is true

C

Both (a) and (b) are true

D

Both (a) and (b) are false

Six students of a school – Radha, Raj, Rahul, Mira, Aarav and Arijit are selected from different classes – 7th, 8th, 9th, 10th, 11th and 12th standards (not necessarily in the same order) to perform individually in the school annual function. Their order of performances is decided as per their classes. The one who is in 12th class will perform first, then after that 11th class student will perform and so on. Mira will perform immediate after the Rahul but before Arijit. Mira does not study in 8th class. Raj will perform immediate after Aarav but Raj neither studies in 8th class nor in 7th class. Who will perform last in the school annual function?

A

Mira

B

Arijit

C

Radha

D

Rahul

The Gaussian kernel is also called the RBF kernel, for Radial Basis Functions.

A

True

B

False

Given that the time dependent Schrodinger equation preserves the wavefunction normalization, does this mean that the time independent Schrodinger equation, i.e. φ(x), preserves this normalization criteria?

A

Yes, because the time dependent equation is a subset of the time independent equation

B

Yes, because the time dependent equation is not a subset of the time independent equation

C

No, because the time dependent equation is a subset of the time independent equation

D

No, because there is no position derivative or variables term that allows φ—→ 0 as x—→ ±∞.
