hello community, i'm new (as member) site, if think might better post on http://datascience.stackexchange.com , let me know. i tackling machine learning problem requires calculate distance between nxm-dimensional elements, in order implement classification algorithms. the element's attribute 2d matrix ( matr ), i'm searching best algorithm calculate distance between 2d matrices. see bellow "easy" solution convert 2d 1d (vector) , implement distance algorithm, i'm searching more convenient (if exists). so far have used following approaches: euclidean distance between each element. import numpy np def dist_euclidean(elem1, elem2): t_sum=0 in range(len(elem1.matr)): j in range(len(elem1.matr[0])): t_sum+= np.square(elem1.matr[i][j]-elem2.matr[i][j]) return np.sqrt(t_sum) cosine similarity, in had convert (nxm) 2d matrix (1xnm) vector. from scipy.spatial import distance def dist_cosine(elem1, elem2): te...

i have working sidenav demo here using angular 2, typescript, , material design components. on sidenav there ul, , sites , users anchors in ul expand show own sub-list. plunker here here's html of sidenav: <md-sidenav #start mode="over" class="sidedrawer"> <ul class="sidenav"> <li><a>dashboard</a></li> <li> <a (click)="sidenavclick()">sites</a> <div> <ul *ngif="clickedsites" class="sublist"> <li><a (click)='sidenavalert()'>all sites</a></li> <li><a>site groups</a></li> </ul> </div> </li> <li> <a (click)="sidenavclickuser()">users</a> <div> <ul *ngif="clickedusers" class="sublist"...
