my main problem is that, i don"t underst& what argmax means in this equation (page 134., figure 4., the output part)

I want lớn write a code, but i don"t underst& this equation. Is there any simpler form of this equation ? (maybe an example)

This is how i underst& it:1. i count the sum first2. i find the argmax

Sorry for my dummy question, but i am not realy good in this area.Thanks for your answers ! Lets say we have a funktion \$f(x) = -(x-2)^2 + 3\$, which has a global maximum at \$x_0=2\$ with \$f(x_0)=3\$.

This means that \$max(f) = 3\$. \$arg!max\$ answers not how high the maximum is, but where it occurs: \$arg!max(f) = 2\$.

cảnh báo that \$f(arg!max(f)) = max(f)\$. In general \$\$x^*=arg max_x f(x) \$\$ means return \$x\$ that maximizes \$f(x)\$.

How khổng lồ find \$x^*\$? 1) Find \$f(x)\$ for all possible values of \$x\$ as \$x_n,,f(x_n)\$. 2) Find the maximum value of \$f(x)\$ in the phối \$f(x_n)\$, let"s denote it by \$f(x_max)\$. 3) return \$x_max\$.

You don"t have lớn store all values. You can start by saying that \$x_max=x_1,,f_max=f(x_1)\$. Then if \$f(x_2)>f_max\$ update the values as \$x_max=x_2,,f_max=f(x_2)\$. If not, keep the previous values. When all the possible values of \$x\$ are considered, your \$x_max\$ at the end will be the value you are looking for.
