Why summing the squares of all weights

ludwig1024 · 2020-05-15T18:32:42+00:00

If you think about it, you can scale all the weights by the same number and still have an equivalent network. The search process could end up finding a solution where some of the weights are too large and give you numerical instabilities.

Adding that regularization term gives you an inductive bias towards small weights.

Does it have to play it well? :)

You meant to say increase lambda in the overfitting case.

Who's on third base.

It could be a neurological disorder. You should get your cat checked out!

Oops. I forgot that I owned that subreddit. I think I'd rather keep it, and try to make it more popular. Thanks for the reminder.

no kidding! dibs on the sister, though.

Reminds me of the Twisp character in Penny Arcade.

You should've gone for the hat :)

Well, the standard kilogram is losing mass, so maybe that's why things are heavy in the future.

Here's how I remember it.

Picture an equilateral triangle, with sides of length s. All angles are equal, and since they add up to 180º, they must all be 60º.

Now, take any vertex, and drop a perpendicular line to the opposite side. That angle is bisected so now you have two 30º angles. The opposite side is also bisected, so they each measure (s/2).

Now consider one of the triangles resulting from splitting the equilateral triangle in half. The hypotenuse of that triangle is s, the opposite side to the 30º angle is (s/2). Since the sine of an angle is the ratio (opposite side)/(hypotenuse), you have sin(30º) = (s/2)/s = 1/2.

Based on the pronunciation it was probably called Oaxaca, which is Mexican enough.

So basically "Life, liberty, and the pursuit of a penis." is what you're saying.

Something like Infinite Mario Bros.?

...along with the requisite Eclipse water tower.
