In this problem we will derive an expression for λmax. Use the Lasso objective function excluding the bias term i.e, J(w) = ∥Xw

− y∥2 + λ ∥w∥1. We will show that for any λ ≥ 2∥XT y∥[infinity], the estimated weight vector wˆ is entirely zero, where ∥ · ∥[infinity] is the infinity norm (or supremum norm), which is the maximum absolute value of any component of the vector.

Why can't irrational numbers be whole numbers
meriva
Irrational numbers cannot be represented by a ratio of two integers.

All whole numbers, however, can. This can be done by placing the number over 1. For example 0/1, 34/1, 173635278/1.

Find the value of x and y
slava [35]

Answer:

Step-by-step explanation:

OS ≅ OU, so we will set those 2 expressions equal to each other and solve for y:

6y = 42 so

y = 7

Same goes for OT and OV:

x + 5 = 23 so

x = 18 and

SU = 84

Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
blondinia [14]
Let the two integers be x and x + 1, then
2(x + 1) + 9 = 3x
2x + 2 + 9 = 3x
3x - 2x = 11
x = 11

Therefore, the integers are 11 and 12.

Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enoug
jolli1 [7]
I believe the answer is C - 60 inches. 60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.
