The advent of low-cost mass-sequencing of genomespresents significant data management difficulties.These will grow worse as it becomes routine tosequence the genomes of individual people andorganisms, because existing systems store and searcheach genome separately. This approach is notfeasible for searching andcomparing the genomes of millions or billions ofindividual organisms. This book seeks to solve thisproblem by describing the DASH sequence alignment andcompression algorithms. DASHmakes use of the overwhelming similarities amongstgenomes of a given species in order to compress, notonly the database size, but also the index size andsearch time. The resulting novel approach todatabase compression, index compression,bioinformatics and information-retrieval should be ofespecial interest to anyone who has an interest inthe storage and efficient searching of large datasets, whether DNA or any other subject which offerssome degree of redundancy, such as natural languagetext or web pages.
Python programmers will improve their computer science skills with these useful one-liners.Python One-Liners will teach you how to read and write "one-liners": concise statements of useful functionality packed into a single line of code. You'll learn how to systematically unpack and understand any line of Python code, and write eloquent, powerfully compressed Python like an expert.The book's five chapters cover tips and tricks, regular expressions, machine learning, core data science topics, and useful algorithms. Detailed explanations of one-liners introduce key computer science concepts and boost your coding and analytical skills. You'll learn about advanced Python features such as list comprehension, slicing, lambda functions, regular expressions, map and reduce functions, and slice assignments. You'll also learn how to:- Leverage data structures to solve real-world problems, like using Boolean indexing to find cities with above-average pollution- Use NumPy basics such as array, shape, axis, type, broadcasting, advanced indexing, slicing, sorting, searching, aggregating, and statistics- Calculate basic statistics of multidimensional data arrays and the K-Means algorithms for unsupervised learning- Create more advanced regular expressions using grouping and named groups, negative lookaheads, escaped characters, whitespaces, character sets (and negative characters sets), and greedy/nongreedy operators- Understand a wide range of computer science topics, including anagrams, palindromes, supersets, permutations, factorials, prime numbers, Fibonacci numbers, obfuscation, searching, and algorithmic sortingBy the end of the book, you'll know how to write Python at its most refined, and create concise, beautiful pieces of "Python art" in merely a single line.
