O(1):constant - the operation doesn't depend on the size of its input, e.g. adding a node to the tail of a linked list where we always maintain a pointer to the tail node.int i=0;i++;++i;i+=6; O(n):linear - the run time complexity is proportionate to…

Motivation We can not talk about Object Oriented Programming without considering the state of the objects. After all object oriented programming is about objects and their interaction. The cases when certain objects need to be informed about the chan…

A Pattern Language for Parallel Application Programming Berna L. Massingill, Timothy G. Mattson, Beverly A. Sanders Abstract Parallel computing has failed to attract significant numbers of programmers outside the specialized world of supercomputing.…

Scripted AI and Scripting Engines 脚本AI与脚本引擎 This chapter discusses some of the techniques you can use to apply a scripting system to the problem of game AI, and the benefits you can reap from doing this. At its most basic level, you can think of scri…

Nested classes are further divided into two types: static nested classes: If the nested class is static, then it’s called static nested class. Static nested classes can access only static members of the outer class. Static nested class is same as any…

1 match = re.search(pat,str)  If the search is successful, search() returns a match object or None otherwise. The code match = re.search(pat, str) stores the search result in a variable named "match". Then the if-statement tests the match -- if…

DescribingDesign Patterns 描述设计模式 How do we describe design patterns?Graphical notations, while important and useful, aren't sufficient. They simply capture the end product of thedesign process as relationships between classesand objects. To reuse the…

by 南大周志华 摘要 监督学习技术通过学习大量训练数据来构建预测模型,其中每个训练样本都有其对应的真值输出.尽管现有的技术已经取得了巨大的成功,但值得注意的是,由于数据标注过程的高成本,很多任务很难获得如全部真值标签这样的强监督信息.因此,能够使用弱监督的机器学习技术是可取的.本文综述了弱监督学习的一些研究进展,主要关注三种弱监督类型:不完全监督,即只有一部分样本有标签:不确切监督,即训练样本只有粗粒度的标签:以及不准确监督,即给定的标签不一定总是真值. 关键词:机器学习,弱监督学习,监督学习…
