摘要： A method and system are disclosed for generating a decision-tree classifier from a training set of records, independent of the system memory size. The method comprises the steps of: generating an attribute list for each attribute of the records, sorting the attribute lists for numeric attributes, and generating a decision tree by repeatedly partitioning the records using the attribute lists. For each node, split points are evaluated to determine the best split test for partitioning the records at the node. Preferably, a gini index and class histograms are used in determining the best splits. The gini index indicates how well a split point separates the records while the class histograms reflect the class distribution of the records at the node. Also, a hash table is built as the attribute list of the split attribute is divided among the child nodes, which is then used for splitting the remaining attribute lists of the node. The created tree is further pruned based on the MDL principle, which encodes the tree and split tests in an MDL-based code, and determines whether to prune and how to prune each node based on the code length of the node.
摘要翻译：公开了用于从记录的训练集合生成决策树分类器的方法和系统，与系统存储器大小无关。该方法包括以下步骤：为记录的每个属性生成属性列表，对数字属性的属性列表进行排序，以及通过使用属性列表重复分割记录来生成决策树。对于每个节点，分析点进行评估，以确定分区节点上的记录的最佳分割测试。优选地，使用基尼系数索引和类别直方图来确定最佳分割。 gini指数表示分割点将记录分离成多少，而类直方图反映了节点上记录的类分布。此外，由于分割属性的属性列表在子节点之间划分，因此构建了哈希表，然后用于分割节点的剩余属性列表。基于MDL原理进一步修剪创建的树，MDL原理对基于MDL的代码中的树和分割测试进行编码，并根据节点的代码长度确定是否修剪和如何修剪每个节点。

摘要： A method and system are disclosed for generating a decision-tree classifier in parallel in a multi-processor system, from a training set of records. The method comprises the steps of: partitioning the records among the processors, each processor generating an attribute list for each attribute, and the processors cooperatively generating a decision tree by repeatedly partitioning the records using the attribute lists. For each node, each processor determines its best split test and, along with other processors, selects the best overall split for the records at that node. Preferably, the gini-index and class histograms are used in determining the best splits. Also, each processor builds a hash table using the attribute list of the split attribute and shares it with other processors. The hash tables are used for splitting the remaining attribute lists. The created tree is then pruned based on the MDL principle, which encodes the tree and split tests in an MDL-based code, and determines whether to prune and how to prune each node based on the code length of the node.

摘要： A method and apparatus are disclosed for generating a decision tree classifier from a training set of records. The method comprises the steps of: pre-sorting the records based on each numeric record attribute, creating a decision tree breadth-first, and pruning the tree based on the MDL principle. Preferably, the pre-sorting includes generating a class list and attribute lists, and independently sorting the numeric attribute lists. The growing of the tree includes evaluating possible splitting criteria and selecting a splitting test for each leaf node, based on a splitting index, and updating the class list to reflect new leaf nodes. In a preferred embodiment, the splitting index is a gini index. The pruning preferably includes encoding the decision tree and splitting tests in an MDL-based code, and determining whether to convert a node into a leaf node, prune its child nodes, or leave the node intact, based on the code length of the node.

摘要： In one exemplary aspect, a method of an anonymous online social network includes the step of providing an anonymous online social networking service. A user is enabled to create a user's anonymous profile on the anonymous online social networking service. The user's anonymous profile comprises a unique social number identifier. A user information is received by a server of the anonymous online social network. The user information includes an anonymous user interest and an anonymous attribute. A search functionality is provided wherein another user searches for the user's anonymous profile utilizing the anonymous user interest and the anonymous attribute. The unique social number identifier can be a user profile identified by a unique sequence of numbers such that the user's profile does not include personal identifying information about the user. The anonymous online social networking service can include a computing platform to build social networks and social relations among a set of users.

摘要： Provisioning remote access points for use in a telecommunication network. A remote access point contains identity information established during manufacturing; this identity information may be in the nature of a digital certificate. The identity information is stored in the remote access point, and may be stored in a Trusted Platform Module if present. When the remote access node is powered up in unprovisioned state, outside the manufacturing environment, it attempts to establish an internet connection via a first wired interface, and queries a user for information representing the TCP/IP address of its controller via a second wired interface. Once an internet connection is present, and a TCP/IP address has been provided, the remote access point attempts to connect to the controller at that address. The controller may filter connection requests through a whitelist of approved remote access points. Once a connection is established, controller and access point exchange and verify each other's identities. This may be done through the exchange and verification of digital certificates. Provisioning information is downloaded from controller to remote access point and installed. This may be done via a tunnel such as an encrypted tunnel. Software updates may be applied. The provisioned remote access point is placed in operation.
