  2. Bottom–up and top–down design - Wikipedia

    en.wikipedia.org/wiki/Bottom–up_and_topdown...

    Top–down methods were favored in software engineering until the late 1980s, [2] [failed verification] and object-oriented programming assisted in demonstrating the idea that both aspects of top-down and bottom-up programming could be used. Modern software design approaches usually combine top–down and bottomup approaches. Although an ...

  3. Bottom-up - Wikipedia

    en.wikipedia.org/wiki/Bottom-up

    Bottom-up parsing, a computer science strategy; Bottom-up processing, in Pattern recognition (psychology) Bottom-up theories of galaxy formation and evolution; Bottom-up tree automaton, in data structures; Bottom-up integration testing, in software testing; Top-down and bottom-up design, strategies of information processing and knowledge ordering

  4. Top-down - Wikipedia

    en.wikipedia.org/wiki/Top-down

    Top-down reading, is a part of reading science that explains the reader's psycholinguistic strategies in using grammatical and lexical knowledge for comprehension rather than linearly decoding texts. Top-down proteomics, a method for protein analysis; Top-down effects, effects of population density on a resource in a soil food web

  5. Reading comprehension - Wikipedia

    en.wikipedia.org/wiki/Reading_comprehension

    Reading different types of texts requires the use of different reading strategies and approaches. Making reading an active, observable process can be very beneficial to struggling readers. A good reader interacts with the text in order to develop an understanding of the information before them.

  6. Hierarchical clustering - Wikipedia

    en.wikipedia.org/wiki/Hierarchical_clustering

    Agglomerative: This is a "bottom-up" approach: Each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy. Divisive: This is a "top-down" approach: All observations start in one cluster, and splits are performed recursively as one moves down the hierarchy.

  7. Pattern recognition (psychology) - Wikipedia

    en.wikipedia.org/wiki/Pattern_recognition...

    In psychology and cognitive neuroscience, pattern recognition is a cognitive process that matches information from a stimulus with information retrieved from memory. [1]Pattern recognition occurs when information from the environment is received and entered into short-term memory, causing automatic activation of a specific content of long-term memory.

  8. Systems biology - Wikipedia

    en.wikipedia.org/wiki/Systems_biology

    In approaching a systems biology problem there are two main approaches. These are the top down and bottom up approach. The top down approach takes as much of the system into account as possible and relies largely on experimental results. The RNA-Seq technique is an example of an experimental top down approach. Conversely, the bottom up approach ...

  9. Bottom-up parsing - Wikipedia

    en.wikipedia.org/wiki/Bottom-up_parsing

    Top-down parsing eagerly decides what a construct is much earlier, when it has only scanned the leftmost symbol of that construct and has not yet parsed any of its parts. Left corner parsing is a hybrid method that works bottom-up along the left edges of each subtree, and top-down on the rest of the parse tree.
