Ira Lisetskai [31]

Answer:

see explanation

Step-by-step explanation:

Using cross- products, that is

\frac{a}{b} = \frac{c}{d} then ad = bc

Given the ratios

\frac{4}{14} and \frac{6}{21}

Then equating and using cross- products

If both sides equate then the ratios are equivalent

\frac{4}{14} = \frac{6}{21}, then

4 × 21 = 6 × 14 ⇒ 84 = 84

Both sides are equal thus the ratios are equivalent

For any two documents x and z, define k(x; z) to equal the number of unique words that occur in both x and z (i.e., the size of
liq [111]

Answer:

Yes, the function is a kernel

Step-by-step explanation:

Given

Document x an z

Function definition! k(x:z)

We want to show that the above is a kernel.

To do this, we'll explicitly construct feature vectors φ(x) and φ(z)

This gives;

K(x,z) =φ(x)·φ(z).

Given than any document; say x and z

A vocabulary V can be constructed.

Vocabulary V must have a finite size of words in the document set..

The feature mapping is constructed as φ(x) for x by the following:

For the kth word wk in V, if wk appears in document x, assign φ(x) k(the kth element ofφ(x)) to be 1; else φ(x)k to 0.

Then the number of unique words common in x and z is φ(x)·φ(z), giving us the kernel
