C++实现基于用户的协同过滤
算法过程:1).读入数据,将数据用user_brands存起来,同时建立userid_id,再建立id_brands 2).遍历id_brands得到物品-用户倒排表brand_ids,根据倒排表得到用户的相似矩阵sim_mat 3).为每个用户推荐产品: 3.1).求用户u买过的brand和所有brand的差集得到用户u没有买过的物品集合brand_unused; 3.2).用户u对每一个没用过的物品i的兴趣p(u,i): 3.2.1).找到与用户u最近的k个用户 对于每一个没用过的物品i: 3.2.2).找出这k个用户中对物品i有过行为的用户v[]√ 3.2.3).将用户u和v[j]的兴趣相似度累加 3.3).取前m个最感兴趣的brand推荐给用户; 代码:UCF.cc(用户协同过滤核心代码):#include #include #include #include #include #include #include #include #include #include

一致性算法验证
分布性一致性算法的Isabella验证 we introduce a novel Broadcast-Free Algorithm that solves Consensusproblem in the presence of a Weak-Fairness property and an unreliablefailure detector -property, in asynchronous distributed systems, and later itsformal verication. The Broadcast-Free Algorithm Model is dened as a globaltransition system that is unambigously generated by local transition rules. At thesystem run, the algorithm model attempts involves two concepts : one to systemrun represents a innite computation and one to asynchronous communicationbetween processes without Broadcast.
