This is a presentation that I presented for my partial fulfillment of the course Optimization Methods for Machine Learning at IIT Gandhinagar. These slides contain an introduction to Alternating Direction Methods of Multipliers and how is the method used in creating distributed optimization algorithms.
Nodal Domain Theorem for the p-Laplacian on Graphs and the Related Multiway C...Francesco Tudisco
We consider the p-Laplacian on discrete graphs, a nonlinear operator that generalizes the standard graph Laplacian (obtained for p=2). We consider a set of variational eigenvalues of this operator and analyze the nodal domain count of the corresponding eigenfunctions. In particular, we show that the famous Courant’s nodal domain theorem for the linear Laplacian carries over almost unchanged to the nonlinear case. Moreover, we use the nodal domains to prove a higher-order Cheeger inequality that relates the k-way graph cut to the k-th variational eigenvalue of the p-Laplacian
Small updates of matrix functions used for network centralityFrancesco Tudisco
Many relevant measures of importance for nodes and edges of a network are defined in terms of suitable entries of matrix functions $f(A)$, for different choices of $f$ and $A$. Addressing the entries of $f(A)$ can be computationally challenging and this is particularly prohibitive when $A$ undergoes a perturbation $A+\delta A$ and the entries of $f(A)$ have to be updated. Given the adjacency matrix $A$ of a graph $G=(V,E)$, in this talk we consider the case where $\delta A$ is a sparse matrix that yields a small perturbation of the edge structure of $G$.
In particular, we present a bound showing that the variation of the entry $f(A)_{u,v}$ decays exponentially with the distance in $G$ that separates either $u$ or $v$ from the set of nodes touched by the edges that are perturbed. Our bound depends only on the distances in the original graph $G$ and on the field of values of the perturbed matrix $A+\delta A$. We show several numerical examples in support of the proposed result.
Talk presented at the IMA Numerical Analysis and Optimization conference, Birmingham 2018
The talk is based on the paper:
S. Pozza and F. Tudisco, On the stability of network indices defined by means of matrix functions, SIMAX, 2018
We are interested in finding a permutation of the entries of a given square matrix so that the maximum number of its nonzero entries are moved to one of the corners in a L-shaped fashion.
If we interpret the nonzero entries of the matrix as the edges of a graph, this problem boils down to the so-called core–periphery structure, consisting of two sets: the core, a set of nodes that is highly connected across the whole graph, and the periphery, a set of nodes that is well connected only to the nodes that are in the core.
Matrix reordering problems have applications in sparse factorizations and preconditioning, while revealing core–periphery structures in networks has applications in economic, social and communication networks.
Complexity Classes and the Graph Isomorphism Problemcseiitgn
The Graph Isomorphism problem is one of the few problems in NP, but not expected to be NP complete and not known to be in P.In this talk I will review some of the attempts that have been made in order to provide a better classification of the problem in terms of complexity classes reviewing upper and lower bounds and illustrating in this way the utility of several complexity classes.

These are my notes for a presentation I did internally at IM. It covers both the multinomial and multi-variate Bernoulli event models in Naive Bayes text classification.
Likelihood is sometimes difficult to compute because of the complexity of the model. Approximate Bayesian computation (ABC) makes it easy to sample parameters generating approximation of observed data.
To describe the dynamics taking place in networks that structurally change over time, we propose an approach to search for attributes whose value changes impact the topology of the graph. In several applications, it appears that the variations of a group of attributes are often followed by some structural changes in the graph that one may assume they generate. We formalize the triggering pattern discovery problem as a method jointly rooted in sequence mining and graph analysis. We apply our approach on three real-world dynamic graphs of different natures - a co-authoring network, an airline network, and a social bookmarking system - assessing the relevancy of the triggering pattern mining approach.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images
