This document discusses the PageRank algorithm developed by Larry Page for ranking web pages. It introduces the motivation for developing PageRank to bring order to the unstructured web based on link analysis. It then describes the random surfer model that PageRank is based on and how it approximates page importance based on the quantity and quality of backlinks. The document concludes by discussing applications of PageRank and some issues with the algorithm, such as its inability to account for user intent in queries.

Incremental Page Rank Computation on Evolving Graphs : NOTESSubhajit Sahu
Highlighted notes while doing research work under Prof. Dip Sankar Banerjee and Prof. Kishore Kothapalli:
Incremental Page Rank Computation on Evolving Graphs.
https://dl.acm.org/doi/10.1145/1062745.1062885
This paper describes a simple method for computing dynamic pagerank, based on the fact that change of out-degree of a node does not affect its pagerank (first order markov property). The part of graph which is updated (edge additions / edge deletions / weight changes) is used to find the affected partition of graph using BFS. The unaffected partition is simply scaled, and pagerank computation is done only for the affected partition.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

7. PageRank Pages with lots of backlinks are important Backlinks coming from important pages convey more importance to a page Problem: Rank Sink
8. Rank Sink Page cycles pointed by some incoming link Problem: this loop will accumulate rank but never distribute any rank outside
9. Escape Term Solution: Rank Source c is maximized and = 1 E(u) is some vector over the web pages – uniform, favorite page etc.
10. Matrix Notation R is the dominant eigenvector and c is the dominant eigenvalue of because c is maximized
11. Computing PageRank - initialize vector over web pages loop: - new ranks sum of normalized backlink ranks - compute normalizing factor - add escape term - control parameter while - stop when converged
12. Random Surfer Model Page Rank corresponds to the probability distribution of a random walk on the web graphs E(u) can be re-phrased as the random surfer gets bored periodically and jumps to a different page and not kept in a loop forever
13. Implementation Computing resources — 24 million pages — 75 million URLs Memory and disk storage Weight Vector (4 byte float) Matrix A (linear access)
14. Implementation (Con't) Unique integer ID for each URL Sort and Remove dangling links Rank initial assignment Iteration until convergence Add back dangling links and Re-compute
15. Convergence Properties Graph (V, E) is an expander with factor if for all (not too large) subsets S: |As| |s| Eigenvalue separation: Largest eigenvalue is sufficiently larger than the second-largest eigenvalue Random walk converges fast to a limiting probability distribution on a set of nodes in the graph.
17. Personalized PageRank Rank Source E can be initialized : – uniformly over all pages: e.g. copyright warnings, disclaimers, mailing lists archives result in overly high ranking – total weight on a single page, e.g. Netscape, McCarthy great variation of ranks under different single pages as rank source – and everything in-between, e.g. server root pages allow manipulation by commercial interests
18. Applications I Estimate web traffic – Server/page aliases – Link/traffic disparity, e.g. porn sites, free web-mail Backlink predictor – Citation counts have been used to predict future citations – very difficult to map the citation structure of the web completely – avoid the local maxima that citation counts get stuck in and get better performance
19. Applications II - Ranking Proxy Surfer's Navigation Aid Annotating links by PageRank (bar graph) Not query dependent
20. Issues Users are no random walkers – Content based methods Starting point distribution – Actual usage data as starting vector Reinforcing effects/bias towards main pages How about traffic to ranking pages? No query specific rank Linkage spam – PageRank favors pages that managed to get other pages to link to them – Linkage not necessarily a sign of relevancy, only of promotion (advertisement…)
23. Conclusion PageRank is a global ranking based on the web's graph structure PageRank use backlinks information to bring order to the web PageRank can separate out representative pages as cluster center A great variety of applications
