We study the misclassification error for community detection in general heterogeneous stochastic block models (SBM) with noisy or partial label information. We establish a connection between the misclassification rate and the notion of minimum energy on the local neighborhood of the SBM. We develop an optimally weighted message passing algorithm to reconstruct labels for SBM based on the minimum energy flow and the eigenvectors of a certain Markov transition matrix. The general SBM considered in this paper allows for unequal-size communities, degree heterogeneity, and different connection probabilities among blocks. We focus on how to optimally weigh the message passing to improve misclassification.

Abstract:
The Poisson clumping heuristic has lead Aldous to conjecture the value of the oriented first passage percolation on the hypercube in the limit of large dimensions. Aldous’ conjecture has been rigorously confirmed by Fill and Pemantle ( Ann. Appl. Probab. 3 (1993) 593–629) by means of a variance reduction trick. We present here a streamlined and, we believe, more natural proof based on ideas emerged in the study of Derrida’s random energy models.

Abstract:
We study the rate of convergence in the celebrated Shape Theorem in first-passage percolation, obtaining the precise asymptotic rate of decay for the probability of linear order deviations under a moment condition. Our results are presented from a temporal perspective and complement previous work by the same author, in which the rate of convergence was studied from the standard spatial perspective.

Abstract:
We investigate a model for opinion dynamics, where individuals (modeled by vertices of a graph) hold certain abstract opinions. As time progresses, neighboring individuals interact with each other, and this interaction results in a realignment of opinions closer towards each other. This mechanism triggers formation of consensus among the individuals. Our main focus is on strong consensus (i.e., global agreement of all individuals) versus weak consensus (i.e., local agreement among neighbors). By extending a known model to a more general opinion space, which lacks a “central” opinion acting as a contraction point, we provide an example of an opinion formation process on the one-dimensional lattice $mathbb{Z}$ with weak consensus but no strong consensus.

Abstract:
We build on recent work concerning message passing approaches to approximate fitting and inference for arbitrarily large regression models. The focus is on regression models where the response variable is modeled to have an elaborate distribution, which is loosely defined to mean a distribution that is more complicated than common distributions such as those in the Bernoulli, Poisson and Normal families. Examples of elaborate response families considered here are the Negative Binomial and $t$ families. Variational message passing is more challenging due to some of the conjugate exponential families being non-standard and numerical integration being needed. Nevertheless, a factor graph fragment approach means the requisite calculations only need to be done once for a particular elaborate response distribution family. Computer code can be compartmentalized, including that involving numerical integration. A major finding of this work is that the modularity of variational message passing extends to elaborate response regression models.

A l’approche de la décision de la SADC, il est important qu’elle porte toute son attention sur les mesures qui permettent de garantir l’équité de traitement entre les protagonistes. Sans modifier le texte de la feuille de route, les autorités ont la possibilité de prouver leur volonté de garantir la neutralité du processus, afin que l’opposition soit libre de faire le choix d’entrer ou non dans cette transition sur une base équilibrée. Le rejet des autorités de ces mesures exposerait leur absence de volonté de voir se dérouler une transition et des élections crédibles. Il démontrerait également leur choix de plonger le pays dans l’instabilité plutôt que d’accepter des mesures qui renforcent la transition. Le refus de l’opposition d’adhérer au processus ne pourrait plus être justifié par un déséquilibre de la solution proposée.

Vatican City, May 7, 2020 / 08:00 am (CNA).- It is important for Catholics to remember the whole of salvation history, and our belonging to the people of God’s covenant with Abraham, Pope Francis said at Mass Thursday.

During daily Mass in the chapel of his Vatican residence, the Casa Santa Marta, Pope Francis reflected on an aspect of the day’s first reading from the Acts of the Apostles, when St. Paul is invited to speak in the synagogue in Antioch.

Instead of speaking directly about Jesus, the apostle begins by telling the history of salvation, the pope noted May 7.

“What is behind Jesus? There is a story. A story of grace, a story of election, a story of promise. The Lord chose Abraham and went with his people,” he said.

“There is a story of God with his people. And for this reason, when Paul is asked to explain the reason for faith in Jesus Christ, he does not start from Jesus Christ: he begins from history.”

The pope pointed to the first part of the entrance antiphon recited at the start of that Mass: “O God, when you went forth before your people, marching with them and living among them...”

He urged Catholics to remember to “pass down the history of our salvation,” and to ask the Lord to help them have the awareness of being children of Abraham, as the Virgin Mary says in the Magnificat and Zechariah in his Benedictus, canticles which are recited or sung in the Liturgy of the Hours.

Christianity, the pope said, is belonging to the people with whom the Lord made his covenant.

Pope Francis also spoke in his homily about what he thinks Christianity is not.

“Christianity is a doctrine, yes, but not only,” he stated. “Christianity is not just an ethic. Yes, indeed, it has moral principles,” but it is not just having an ethical viewpoint.

Francis went on to say that Christianity is also more than an exclusionary vision of an “‘elite’ of people chosen for the truth.” He criticized when this attitude comes into the Church as a belief in the damnation of others.

It is good to be a moral people, he said, but “Christianity is belonging to a people, to a people freely chosen by God.”

“If we do not have this awareness of belonging to a people we would be ideological Christians,” he said.

The pope explained that this is why, in order to speak about Jesus, St. Paul starts by explaining “from the beginning, from belonging to a people.”

He warned that when Christians lose the sense of belonging to the people of God’s covenant, they often fall into “partialities,” whether dogmatic, moral, or elitist.

Francis called this “the most dangerous deviation” Christians can fall into today.

Before Mass, Pope Francis noted that he had received a letter from a group of artists, thanking him for remembering them in prayer in April.

He added that he “would like to ask the Lord to bless them because artists make us understand what beauty is and without beauty the Gospel cannot be understood.”

“Let’s pray for artists again,” he urged.

After Mass, the pope concluded the livestream with Eucharistic adoration, benediction, and the Marian antiphon “Regina coeli.”
