derivative. From the de nition of matrix-vector multiplication, the value ~y 3 is computed by taking the dot product between the 3rd row of W and the vector ~x: ~y 3 = XD j=1 W 3;j ~x j: (2) At this point, we have reduced the original matrix equation (Equation 1) to a scalar equation. This makes it much easier to compute the desired derivatives.

MapReduce is a popular fault-tolerant framework for distributed applications. Nevertheless, heavy disk I/O at each MapReduce operation hinders the implementation of efficient iterative data mining algorithms, such as Apriori, on MapReduce platforms.
Matrix-vector multiplication (16 rows, 107 cols) 5 different execution strategies: Sequential Parallelizing only one of the map, reduce and zip Parallelizing all three Two platforms: Laptop with 4 threads and 8GB memory HPC cluster with 8 threads and 32GB memory
To implement Vector Multiplication In MapReduce, our main design consideration is that the elements with the same index have to be grouped together in order to be multiplied. So the key value should be something like, index and the number, from the array. But there's a problem, the files are just numbers.

@PraveenSripati There is ancient code for matrix multiplication in mapreduce and hbase with Hama (~0.2.0 or something). But since this is no iterative process, I don't think that BSP is a better fit than MapReduce in this case ;) - Thomas Jungblut. Mar 16 '12 at 6:47.

Our formulation of matrix-vector multiplication assumed that the matrix M was square. Generalize the algorithm to the case where M is an r-by-c matrix for some number of rows r and columns c. solution. The matrix M and the vector v each will be stored in a file of the DFS.
Map-Reduce also makes short work of dealing with large matrices and can crunch matrix operations like matrix addition, subtraction, multiplication etc. Matrix-Vector multiplication. As an example if we consider a Matrix-Vector multiplication (taken from the book Mining Massive Data Sets by Jure Leskovec, Anand Rajaraman et al
Building on the previous work of Lee et al.  and Ferdinand et al.  on coded computation, we propose a sequential approximation framework for solving optimization problems in a distributed manner. In a distributed computation system, latency caused by individual processors ("stragglers") usually causes a significant delay in the overall process. The proposed method is powered by a ...

In mathematics, particularly in linear algebra, matrix multiplication is a binary operation that produces a matrix from two matrices. For matrix multiplication, the number of columns in the first matrix must be equal to the number of rows in the second matrix. The resulting matrix, known as the matrix product, has the number of rows of the first and the number of columns of the second matrix.
i, into a hidden state vector. The tracking network takes the sequence of embedded inputs (hidden state vector) and generates coordinate vectors l. Coordinate values after the trajectory is ﬁnished are excluded from loss estimation, and y is represented as element-wise multiplication with coordinate vector l and state vector s. Loss is ...
them to generalized sparse matrix vector multiplication operations. We get the productivity beneﬁts of vertex programming while en-joying the high performance of a matrix backend. In addition, it is easy to understand and reason about, while letting users with knowledge of vertex programming a smooth transition to a high performance environment.
Finally, we will briefly take a look at a special form of matrix multiplication, termed as matrix-vector multiplication. A vector is simply a matrix with a single row, which on multiplication with a square matrix of product-compatible size produces a new vector with the same size as the original vector. After multiplying a matrix A of size and ...
Sparse matrix-matrix multiplication (SpGEMM) is a computational primitive that is widely used in areas ranging from traditional numerical applications to recent big data analysis and machine learning.
In its simplest form, it assumes a matrix of ratings given by musers to nitems. Applying this technique on R will end up factorizing R into two matrices and such that (their multiplication approximates R). Note that this algorithm introduces a new quantity, k, that serves as both U's and P's dimensions. This is the rank of the factorization.
When you have a very sparse matrix, with a lot of dimensions, by doing matrix factorization, you can restructure the user-item matrix into low-rank structure, and you can represent the matrix by the multiplication of two low-rank matrices, where the rows contain the latent vector. You fit this matrix to approximate your original matrix, as ...

Recurrence Width for Structured Dense Matrix Vector Multiplication with Albert Gu, Rohan Puttagunta, and Atri Rudra studies the problem of structured matrix-vector multiply, e.g., fourier transforms, orthogonal polynomials, low displacement rank. This work unifies and we think simplifies many known algorithms and extends to a host of new cases.

MapReduce Computation. 14. MapReduce In brief, a MapReduce computation executes as follows: • Chunks from a DFS are given to Map tasks. • These Map tasks turn the chunks into a sequence of <key, value> pairs. • The <key,value> pairs from each Map task are collected by a master controller and sorted by key.
