The document discusses how adding new links can affect Google PageRank. It summarizes that: - Adding links to pages within the same web community as the source page can increase the source page's PageRank. - Simply adding many new links may decrease the PageRank of pages the links point to, if most new links point to irrelevant pages outside the web community. - The optimal linking strategy for a page is to have a single outgoing link that points to the page with the shortest expected time to return to the original page via random walks. Maintaining a logical link structure and relevance is most sensible.

Markov chain
This document summarizes key concepts related to Markov chains and linear algebra. It provides an example of using a transition matrix to model the probabilities of television viewers switching between two stations over time. The transition matrix allows calculating the probability vectors for future weeks through matrix multiplication. A steady-state vector can also be determined by solving the equation A*p=p, representing the long-term probabilities once the system reaches equilibrium.
Lesson 11: Markov Chains
The document discusses Markov chains and their application to modeling transitions between states over time. It defines Markov chains as processes where the probability of the next state depends only on the current state. Transition matrices are used to represent the probabilities of moving between states. The powers of a transition matrix converge to a steady state as time increases, with all columns being identical, representing the long-term probabilities of being in each state. Finding the steady state vector involves solving the equation Tu=u. An example of modeling class attendance as a Markov chain is presented.
Metric space
This document contains definitions, examples, and results related to Cauchy sequences, subsequences, and complete metric spaces. It defines a Cauchy sequence as one where the distances between terms gets arbitrarily small as the sequence progresses. It proves that every convergent real sequence is Cauchy. It also defines subsequences and subsequential limits, and proves properties about them. Finally, it defines a complete metric space as one where every Cauchy sequence converges, and provides examples showing the complex numbers form a complete metric space while some subsets of real numbers do not.
Markov Chains
This document provides a summary of Markov chains. It begins by defining stochastic processes and Markov chains. A Markov chain is a stochastic process where the probability of the next state depends only on the current state, not on the sequence of events that preceded it. The document discusses n-step transition probabilities, classification of states, and steady-state probabilities. It provides examples of Markov chains for cola purchases and camera store inventory to illustrate the concepts.
Markov chains1
This document discusses Markov chains, which are a type of stochastic process used to model randomly changing systems. It defines Markov chains and their key properties, like the Markov property and transition probabilities. It provides examples like modeling customer purchases over time and inventory management. It also covers concepts like steady state probabilities, transition matrices, and mean first passage times.

Done reread thecomputationalcomplexityoflinkbuilding
The document discusses the computational complexity of the problem of adding links to a directed graph to maximize the minimum PageRank value of a subset of nodes. It is shown that the general problem is NP-hard if the number of links to add is part of the input. A simple randomized algorithm is presented for the special case of adding a single link to maximize the PageRank of a given node, with a running time proportional to a small number of PageRank computations. Experimental results using the algorithm on computer-generated and real-world web graphs are also discussed.
Pagerank
This document proposes an improvement to the PageRank algorithm used in search engines like Google. It introduces a "directed surfer model" that guides the random surfer to pages relevant to the search query based on term frequency, instead of allowing completely random jumps. This query-dependent PageRank can be pre-computed for all terms, indexed, and combined at query time efficiently. Experiments showed it significantly outperformed standard PageRank in returning higher quality results while maintaining efficiency for large-scale search engines.
Page rank
This document discusses PageRank, an algorithm used by Google Search to rank websites in their search results. It describes how PageRank works by modeling the web as a directed graph and calculating an importance score for each page based on the page's inlinks. It discusses how PageRank can be formulated as the principal eigenvector of the stochastic link matrix or as the stationary distribution of a random walk on the web graph. It also covers techniques like random teleportation to address issues like spider traps and dead ends.

Newton's method and Gauss-Newton method can be used to minimize a nonlinear least squares function to fit a vector of model parameters to a data vector. The Gauss-Newton method approximates the Hessian matrix as the Jacobian transpose times the Jacobian, ignoring additional terms, making it faster to compute but less accurate than Newton's method. The Levenberg-Marquardt method interpolates between Gauss-Newton and steepest descent methods to provide a balance of convergence speed and accuracy. Iterative methods like conjugate gradients are useful for large nonlinear problems where storing and inverting the full matrix would be prohibitive. L1 regression provides a more robust alternative to L2 regression for dealing with outliers through minimization of the absolute error rather

Examples of recursively defined sequences like Fibonacci are provided. Growth functions are defined using big-O notation to analyze how functions grow relative to each other. Common proof techniques like direct proof, indirect proof, proof by contradiction and induction are described. Walks and paths in trees are defined as sequences of alternating vertices and edges that begin and end at vertices. Deterministic finite automata are defined as 5-tuples with states, input alphabet, transition function, start state, and set of accepting/final states.
Notes.on.popularity.versus.similarity.model
1) The document summarizes a model of network growth where new nodes are added over time and connect to existing nodes proportional to their attractiveness. The attractiveness of each node is its initial attractiveness plus the number of incoming links.
2) An analytic solution is derived for the degree distribution of the network, which follows a power law form.
3) A master equation approach is used to derive a partial differential equation governing the time evolution of the degree distribution, and its analytic solution is obtained.
Orthogonal basis and gram schmidth process
1) The Gram-Schmidt process is used to transform a basis into an orthogonal basis. It works by making each new basis vector orthogonal to the preceding ones.
2) QR factorization states that any matrix A can be decomposed into A = QR, where Q is orthogonal and R is upper triangular.
3) The QR factorization can be used to solve the least squares problem. The solution is obtained by back substituting into Rx=Q^Tb.

Solution
An interpolation assignment generally entails a given set of information points: in which the
values yi can,
xi x0 x1 ... xn
f(xi) y0 y1 ... yn
for instance, be the result of a few bodily measurement or they can come from a long
numerical calculation. hence we know the fee of the underlying characteristic f(x) at the set
of points xi, and we want to discover an analytic expression for f .
In interpolation, the assignment is to estimate f(x) for arbitrary x that lies among the smallest
and the most important xi
. If x is out of doors the variety of the xi’s, then the task is called extrapolation,
which is substantially greater unsafe.
with the aid of far the maximum not unusual useful paperwork utilized in interpolation are the
polynomials.
different picks encompass, as an instance, trigonometric functions and spline features
(mentioned
later during this direction).
Examples of different sorts of interpolation responsibilities include:
1. Having the set of n + 1 information factors xi
, yi, we want to understand the fee of y in the
complete c program languageperiod x = [x0, xn]; i.e. we need to find a simple formulation
which reproduces
the given points exactly.
2. If the set of statistics factors contain errors (e.g. if they are measured values), then we
ask for a components that represents the records, and if feasible, filters out the errors.
3. A feature f may be given within the shape of a pc system which is high priced
to assess. In this case, we want to find a characteristic g which offers a very good
approximation of f and is simpler to assess.
2 Polynomial interpolation
2.1 Interpolating polynomial
Given a fixed of n + 1 records points xi
, yi, we need to discover a polynomial curve that passes
via all the factors. as a consequence, we search for a non-stop curve which takes at the values yi
for every of the n+1 wonderful xi’s.
A polynomial p for which p(xi) = yi whilst zero i n is stated to interpolate the given set of
records points. The factors xi are known as nodes.
The trivial case is n = zero. right here a steady function p(x) = y0 solves the hassle.
The only case is n = 1. In this situation, the polynomial p is a directly line described via
p(x) =
xx1
x0 x1
y0 +
xx0
x1 x0
y1
= y0 +
y1 y0
x1 x0
(xx0)
here p is used for linear interpolation.
As we will see, the interpolating polynomial may be written in an expansion of paperwork,
among
these are the Newton shape and the Lag.

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

Climate Impact of Software Testing at Nordic Testing Days
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

- 1. The effect of New Links on Google Pagerank By Hui Xie Apr , 07
- 12. Outgoing links from i do not affect q ji for any j!=I So by changing the outgoing links, a page can control its PageRank up to multiplication by a factor z ii =1/(1-q ii ) For 0<=q ii <=c 2 , 1<=z ii <=(1-c 2 ) -1 ≈3.6 for c=0.85
- 17. the PageRank of page j increases if
- 18. the PageRank of page j increases if if several new links are added then the PageRank of page j might actually decrease even if this page receives one of the new links. Such situation occurs when most of newly created links point to “irrelevant” pages.
