Binary Codes Based on Non-Negative Matrix Factorization for Clustering and Retrieval
Traditional non-negative matrix factorization methods cannot learn the subspace from the high-dimensional data space composed of binary codes. One hopes to discover a compact parts-based representation composed of binary codes, which can uncover the ...

Lattice Points on the Fermat Factorization Method
In this paper, we study algebraic properties of lattice points of the arc on the conics x2−dy2=N especially for d=1, which is the Fermat factorization equation that is the main idea of many important factorization methods like the quadratic field sieve ...

On the factorization of integrers [PDF]
The order of magnitude of the average of the exponents in the canonical factorization of an integer is discussed. In particular, it is shown that this average has normal order one and a result which implies that the average order is one is also derived.

Factoring Large Integers [PDF]
A modification of Fermat’s difference of squares method is used for factoring large integers. This modification permits factoring n in O ( n 1 / 3 ) O({n^{1/3}}) elementary operations,

On the factorization of consecutive integers [PDF]
A classical result of Sylvester [21] (see also [16], [17]), generalizing Bertrand’s Postulate, states that the greatest prime divisor of a product of k consecutive integers greater than k exceeds k. More recent work in this vein, well surveyed in [18], has focussed on sharpening Sylvester’s theorem, or upon providing lower bounds for the number of ...

Integer Factorization – Cryptology Meets Number Theory
Integer factorization is one of the oldest mathematical problems. Initially, the interest in factorization was motivated by curiosity about behaviour of prime numbers, which are the basic building blocks of all other integers.

A babystep-giantstep method for faster deterministic integer factorization [PDF]
In 1977, Strassen presented a deterministic and rigorous algorithm for solving the problem of computing the prime factorization of natural numbers $N$. His method is based on fast polynomial arithmetic techniques and runs in time $\widetilde{O}(N^{1/4})$,

The factor-difference set of integers [PDF]
The set \(D(n) = \{d:\;d=| a-b| ,\;n=ab\} = \{d_0 < d_1 < \cdots 0\) there are \(k\) distinct integers \(N_1 < N_2 < \cdots

Localized factorizations of integers [PDF]
34 pages. Added reference [10] to a paper of Nair and Tenenbaum which contains a result similar to Lemma 2.2 and which appeared prior to the publication of this paper. Simplified the proof of Lemma 2.2 using ideas from [10]. Removed part (a) of Lemma 2.2, as it is now redundant.
