PP: Deep r -th Root of Rank Supervised Joint Binary Embedding for Multivariate Time Series Retrieval

from: Dacheng Tao 悉尼大学 PROBLEM: time series retrieval: given the current multivariate time series segment, how to obtain its relevant time series segments in the historical data. Two challenging: 1. it requires a compact representation of the raw tim…

PP: Deep clustering based on a mixture of autoencoders

Problem: clustering A clustering network transforms the data into another space and then selects one of the clusters. Next, the autoencoder associated with this cluster is used to reconstruct the data-point. Introduction: traditional method: data----…

PP: Robust Anomaly Detection for Multivariate Time Series through Stochastic Recurrent Neural Network

PROBLEM: OmniAnomaly multivariate time series anomaly detection + unsupervised 主体思想: input: multivariate time series to RNN ------> capture the normal patterns -----> reconstruct input data by the representations ------> use the reconstruction pr…

PP: Toeplitz Inverse Covariance-Based Clustering of Multivariate Time Series Data

From: Stanford University; Jure Leskovec, citation 6w+; Problem: subsequence clustering. Challenging: discover patterns is challenging because it requires simultaneous segmentation and clustering of the time series + interpreting the cluster results…

HDU 3966（树链剖分+点修改+点查询）

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=3966 题目大意:营地的分布成树型.每个营地都有一些人,每次修改修改一条链上的所有营地的人数,每次查询单个点. 解题思路: 树链剖分基础题. 维护一个sum. 注意轻链修改时,点修改和边修改的不同. 由于树的结构与线段树点的顺序不太相同,因此需要做一个映射数组rank.故在线段树Build的时候,权值是camp[rank[l]],rank这步的映射在dfs2的时候完成,rank[w[u]]=u; Qu…

108. Convert Sorted Array to Binary Search Tree (building tree with resursion)

Given an array where elements are sorted in ascending order, convert it to a height balanced BST. For this problem, a height-balanced binary tree is defined as a binary tree in which the depth of the two subtrees of every node never differ by more th…
