Some online prediction problems can be translated into online convex optimization framework. The following two kinds of convexity techniques are introduced:
Some online prediction problems do not seem to fit the online convex optimization framework. For example, in the online classification problem, the prediction domain (predictions domain) or the loss function are not convex. We describe two convex techniques that allow us to use online convex optimization frameworks in other scenarios.
1.Convexification by Randomization
To demonstrate the randomization technique, we...
1 .Create file address
First create a folder, I use the HBuilder editor, then drag the folder into the editor and open CMD in the folder you created

[BZOJ3992] [SDOI2015] sequence statistics”
Description
Small C has a set of S whose elements are all non negative integers less than M. He programmed a sequence generator to generate a N-length sequence in which each number belongs to the set S. Small C uses this generator to generate many such sequences. But little C has a problem that needs you.Help: Given the integer x, find how many different sequences of numbers can be generated that satisfy the value of the product mod M of all the numbers in the sequence equal to X. Small C holds that two sequences {Ai} and {Bi} are different if ...

Let’s tell a sad story. Once upon a time, there was a poor woodcutter cutting firewood beside the river. Then a water God appeared in the river, took his axe and said, “Is this your axe?” The woodcutter looked at him, “yes, yes!” The water God threw the axe aside, and picked up one thing and asked, “this axe,Is it yours? ” The woodcutter could not see clearly, but he was afraid that he was really his axe, so he replied, “yes, yes!” The God of water threw aside the thing on his hand, took the third thing and as...
HDU3336Count the string
Problem Description
It is well known that AekdyCoin is good at string problems as well as number theory problems. When given a string s, we can write down all the non-empty prefixes of this string. For example:s: “abab”The
prefixes are: “a”, “ab”, “aba”, “abab”For each prefix, we can count the
times it matches in s. So we can see that prefix “a” matches twice, “ab” matches
twice too, “aba” matches once, and “abab” matches once. Now you are asked to
calculate the ...
