Enhanced Community Detection in Multilayer and Temporal Networks through Layer Aggregationĭane Taylor, University of North Carolina at Chapel Hill Rajmonda Caceres, Massachusetts Institute of Technology Peter J. The talk is based on recent work in collaboration with Christine Klymko (LLNL) and Francesca Arrigo (Strathclyde). Finally, I will discuss efficient edge modification strategies (including edge removal, addition, and rewiring) that can be used to obtain networks with desirable communicability properties. I will introduce the notion of total communicability of a network as a measure of network connectivity and robustness and show that it can be computed very quickly even for large graphs. These measures can be given an elegant closed form in terms of functions of the adjacency matrix. In this talk I will review some network centrality and communicability measures based on walks. Walk-Based Centrality and Communicability Measures: Algorithms and Applications Numerical results on a variety of synthetic and real-world networks will be presented. This approach gives rise to a class of novel and scalable algorithms that work effectively for large-scale and dense networks. This system is analogous to the Fokker-Planck equation in continuous space, and the solution readily yields the desired influence. We develop a novel and transformative framework that adaptively aggregates the activation states of the network according to the number of active nodes, leading to the construction of a system of differential equations that governs the time evolution of the state probabilities. We consider the problem of predicting influence, defined as the expected number of infected nodes, resulted from information propagating from any given set of source nodes on a network.

This mini-symposium focuses on the recent advances of mathematical modeling and numerical methods as well as their applications in modern network science. New models and computational methods must tackle challenges of inhomogeneous structures of networks, randomness of dynamics, and noise in data. In these applications, big data is often generated, collected, stored and/or processed in large-scale heterogeneous networks. df = pd.DataFrame() df.In recent years, there has been high demand for novel and accurate mathematical models, and fast, stable and scalable computational techniques to address problems emerging from applications on real-world networks, such as social media and power grids. Using these 4 arrays, we can create a pandas dataframe. Since there is a space at the end of the string, the last element of the list is a space (‘ ‘). The first create a string that contains 30 As and 30 Bs (with spaces in between) and then split the string on spaces to create a list of 30 items. Numerical features: x = np.random.random(size=60)*7 + 1 y = np.random.random(size=60)*7 + 1 z = np.random.random(size=60) z = z*5 + 2Ĭategorical feature: categories = "A "*30 + "B "*30 categories = categories.split(" ") categories.pop(60) We use numpy arrays for numerical features and python lists to create category column. We create a dataframe that contains 3 different numerial features on some observations that belong to 2 different categories. import numpy as np import pandas as pd import plotly.express as px

Let’s first create a synthetic dataset using numpy and pandas.

On the other hand, we need to write more code with graph objects but have more control over what we create. With plotly express, we can create a nice plot with very few lines of code. One of the things I like about plotly.py is that it offers a high-level API ( plotly express) and a low level API ( graph objects) to create visualizations. We will use Plotly Python (plotly.py) which is an open-source plotting library built on plotly javascript (plotly.js). In this post, we will create dynamic 3D scatter plots and compare them to 2D scatter plots. Visualizations are great tools that expedite exploring the data and help build a robust data analysis process. Before applying a model to the data, it is highly important to explore and understand the structures within the raw data. As the structure gets more complex, we can represent more information with a visualization. For instance, a 3D dynamic plot can tell much more than a 2D plot. The informative power of visualization depends on its structure. Thus, visualizations are widely used in the field of data science. Informative power of visualizations is hard to achieve with plain text. Visualizations stick in minds much more than plain text or numbers.
