High Performance Discovery in Time Series: Techniques and Case Studies

Time-series data—data arriving in time order, or a knowledge stream—can be present in fields reminiscent of physics, finance, track, networking, and clinical instrumentation. Designing quickly, scalable algorithms for studying unmarried or a number of time sequence can result in clinical discoveries, scientific diagnoses, and maybe earnings.

Example text

Once the program is written, the numbers that it will produce can be deduced, so how could they be random? The best we can hope to do is to write programs which produce isequences of numbers having many of the same properties as random numbers. Such numbers are commonly called pseudo-random numbers: they’re not really random, but they can be useful 33 CHAF’TER 3 as approximations to random numbers, in much the same way that floatingpoint numbers are useful as approximations to real numbers. (Sometimes it’s convenient to make a further distinction: in some situations, a few properties of random numbers are of crucial interest while others are irrelevant.

Also, access to individual elements in linked structures is much more restricted than in arrays. We’ll see examples of the use of these data structures in various algorithms, and we’ll see more complicated data structures that involve more constraints on the elements in an array or more pointers in a linked representation. For example, multidimensional arrays can be defined which use multiple indices to access individual items. Similarly, we’ll encounter many “multidimensional” linked structures with more than one pointer per node.

3. Write an N2 program to do Lagrang:ian interpolation. 4. Suppose that we know that a polynomial to be interpolated is sparse (has few non-zero coefficients). Describe how you would modify Lagrangian interpolation to run in time proportional to N times the number of nonzero coefficients. 5. Write out all of the polynomial multipllications performed when the divideand-conquer polynomial multiplication method described in the text is used tosquare 1+x+~2+x3+s4+x5+x6+~7+xs. 6. The polynomial multiplication routinie mult could be made more efficient for sparse polynomials by returning 0 if all coefficients of either input are 0.
