Lecture 1 ( Sep 8 , 2005 ) : A sample scribe

چکیده
Speed: Randomized algorithms are usually fast, sometimes much faster than any deterministic algorithm for the same problem. Even if the asymptotic running time is the same as the deterministic one it can be faster in practice. For example QuickSort, though has worse-case running time worse than that of MergeSort or Heapsort, it is the fastest algorithm in practice. The disadvantage of some randomized algorithms (like QuickSort) is that sometimes the running time is more than usual. Also, some randomized algorithms produce a solution that is correct with high (but smaller than 1) probability, so there is a chance that the solution is not correct.

From the above definition, we have the following geometrical interpretation of the dual lattice. For any vector x, the set of all points whose inner product with x is integer forms a set of hyperplanes perpendicular to x and separated by distance 1/‖x‖. Hence, any vector x in a lattice Λ imposes the constraint that all points in Λ∗ lie in one of the hyperplanes defined by x. See the next figure...

Theorem 0 from Handout Let X be a domain of examples, and C, H concept classes over X. Let A be a learning algorithm such that ∀c ∈ C A takes a sample of m examples and outputs a hypothesis h ∈ H consistent with sample S. Then when using a sampl...

Acknowledgements These lecture notes began as rough scribe notes for a Fall 2009 offering of the course " Data Stream Algorithms " at Dartmouth College. The initial scribe notes were prepared mostly by students enrolled in the course in 2009. Subsequently, during a Fall 2011 offering of the course, I edited the notes heavily, bringing them into presentable form, with the aim being to create a r...
