问题 I wanted to ask if there was an easy way to visualize a Keras model built from the Functional API? Right now, the best ways to debug at a high level a sequential model for me is: model = Sequential() model.add(... ... print(model.summary()) SVG(model_to_dot(model).create(prog='dot', format='svg')) However, I am having a hard time finding a good way to visualize the Keras API if we build a more complex, non-sequential model. 回答1: Yes there is, try checking the keras.utils which has a method

问题 I would like to draw a circular graph of nodes where certain nodes have a link between them. Here are a few examples from social network graphs: (source: wrightresult.com) (source: twit88.com) How can this be done with MATLAB? Is it possible without installing a separate package? 回答1: Here is one way you can do what you want. First, generate points on the circle that you are interested in clear; theta=linspace(0,2*pi,31);theta=theta(1:end-1); [x,y]=pol2cart(theta,1); Next, if you know the

问题 I'm using Python to simulate a process that takes place on directed graphs. I would like to produce an animation of this process. The problem that I've run into is that most Python graph visualization libraries combine pairs of directed edges into a single edge. For example, NetworkX draws only two edges when displaying the following graph, whereas I would like to display each of the four edges separately: import networkx as nx import matplotlib.pyplot as plt G = nx.MultiDiGraph() G.add_edges

问题 I have some data similar to the data.frame d as follows. d <- structure(list(ID = c("KP1009", "GP3040", "KP1757", "GP2243", "KP682", "KP1789", "KP1933", "KP1662", "KP1718", "GP3339", "GP4007", "GP3398", "GP6720", "KP808", "KP1154", "KP748", "GP4263", "GP1132", "GP5881", "GP6291", "KP1004", "KP1998", "GP4123", "GP5930", "KP1070", "KP905", "KP579", "KP1100", "KP587", "GP913", "GP4864", "KP1513", "GP5979", "KP730", "KP1412", "KP615", "KP1315", "KP993", "GP1521", "KP1034", "KP651", "GP2876",

问题 I have a matrix A in Matlab of dimension mx2 that contains in each row the labels of two nodes showing a direct link in a network, e.g.: if the network has 4 nodes the matrix A could be A=[1 2; 1 3; 2 1; 2 4; 3 2; 4 1; 4 2] , where the first row means that there is a link from 1 to 2 , the second row means that there is a link from 1 to 3 , etc. Could you suggest me a quick way to draw the network from A? 回答1: If you want the links to be directional, and have the Bioinformatics toolbox, you

问题 I am trying to find maximum spanning tree of a network using networkx python module. According to documentation specified[link below], nx.maximum_spanning_tree(G) should do this work. But i am getting error File "air_traffic_network_base.py", line 65, in <module> max_spanning_tree = nx.maximum_spanning_tree(net) AttributeError: 'module' object has no attribute 'maximum_spanning_tree' Here is the code snippet: net = nx.read_weighted_edgelist(graph_file) min_spanning_tree = nx.minimum_spanning

问题 What's the best way to get the link closest to a particular point in netlogo? The best would be a link reporter link-distancexy that takes an xcor and ycor and outputs the closest distance from that point to a point on the link. Next best would just be a general reporter closest-link-xy that takes and xcor and ycor and reports the closest link. This problem is complicated by wrapping boundaries, but an imperfect solutions would still be appreciated. 回答1: This function might work for your

问题 Using the Highstock (Highcharts) library, I'm wondering, how do I combine A) adding flags as in here (or see fig.1 ) with B) dynamically updating data, using the addPoint function (ex: series.addPoint([x, y], true, true) see here). There doesn't seem to be a facility for it in the addPoint function. series : [{ name : 'USD to EUR', data : data, id : 'dataseries' }, { type : 'flags', data : [{ x : Date.UTC(2011, 3, 25), title : 'H', text : 'Euro Contained by Channel Resistance' }], onSeries :

问题 I'm trying to get my D3 network to freeze after it reaches a nice layout (alpha reaches 0). I want the force to stop completely, even when a node is dragged (the user should be able to rearrange the nodes manually). I think I know how to do the second part of this, by modifying the functions that are called on mousedown and mouseup for the nodes. However, I can't get the original layout and freezing to work. I've looked at the examples for "static" force layouts, where the network is

问题 ( This is regarding google-embed-api NOT google charts, Stack Overflow won't let me create a new tag without 1500 reputation) Hello, I'm not incredible at CSS, and am working on a project where I must present a bunch of columns per dimension using googles new charts embed API. The chart is created through a js call to gapi.analytics.googleCharts.DataChart() which creates what I want, perfectly, however the CSS settings in the JS call are overriding the one's I specify. Calling gapi.analytics
