Top–down methods were favored in software engineering until the late 1980s, [3] [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 bottom–up approaches. Although an ...
Instruction for comprehension strategy often involves initially aiding the students by social and imitation learning, wherein teachers explain genre styles and model both top-down and bottom-up strategies, and familiarize students with a required complexity of text comprehension. [15]

There are two main approaches to document layout analysis. Firstly, there are bottom-up approaches which iteratively parse a document based on the raw pixel data. These approaches typically first parse a document into connected regions of black and white, then these regions are grouped into words, then into text lines, and finally into text blocks.
Top down design fuels understanding of an image by using prior experiences and knowledge to interpret a stimulus. This process helps us analyze familiar scenes and objects when encountering them. [3] During perception of any kind, people generally use either sensory data (bottom-up design) or prior knowledge of the stimulus (top-down design ...
Susie Coughlin was concerned when her daughter struggled with reading skills at her public school.. The mom of two was disappointed her district didn't teach phonics as part of its literacy program.
Bottom-up processing is also known as data-driven processing, because it originates with the stimulation of the sensory receptors. [10] Psychologist James Gibson opposed the top-down model and argued that perception is direct, and not subject to hypothesis testing as Gregory proposed.
