Scene parsing from images is a fundamental yet challenging problem in visual content understanding. In composition, if the parent object is destroyed, then the child objects also cease to exist. Composition. I have been trying to freshen up on my programming terminology and the term aggregate is extremely confusing to me. Generalization – Generalization is the process of extracting common properties from a set of entities and create a generalized entity from it. What is the true meaning of an aggregate in computer science? Different wholes may share the same part. Composition is a specialized form of aggregation. A Computer Science portal for geeks. Aggregation-layer submodule. The difference is typically expressed as the difference between "is a" and "has a". Composition. De-allocating the … Computer science and telecommunication. Association indicates the relationship between objects. Computer Science Division Univ ersit y of California, Berk eley jmh@cs.b erk ele y.ed u P eter J. Haas Almaden Researc h Cen ter IBM Researc h Division p eterh@almad en. Aggregate function, a type of function in data processing; Aggregation, a form of object composition in object-oriented programming; Link aggregation, using multiple Ethernet network cables/ports in parallel to increase link speed; Packet aggregation, joining multiple data packets for transmission as a single unit to increase network efficiency The whole may not have a part, or it may have a different part at different times. Generalization, Specialization and Aggregation in ER model are used for data abstraction in which abstraction mechanism is used to hide details of a set of objects. The aggregation-layer submodule plays a pivotal role in providing a highly reliable, scalable “middle layer” for bringing together the traffic from the access-layer submodule, while at the same time ensuring the optimal use of physical resources. Some places say that an aggregate is almost exactly the same as composition except for aggregation does not control its contained objects life-cycle. Median response time is 34 minutes and may be longer for new subjects. Consider the differences and similarities between the classes of the following objects: pets, dogs, tails, owners. eg: Computer uses keyboard as input device. *Response times vary by subject and question complexity. Composition in object oriented programming. So the challenge for this learning task is to simultaneously describe the geometric and semantic properties of objects or a scene. In this dense prediction task, the parsing model assigns every pixel to a categorical label, which requires the contextual information of adjacent image patches. A directional association between objects. Data aggregation is a type of data and information mining process where data is searched, gathered and presented in a report-based, summarized format to achieve specific business objectives or processes and/or conduct human analysis. Aggregation is a special case of association. Aggregation by value cannot be cyclic: one object is the whole, one the part. An association is used when one object wants another object to perform a service for it. Data aggregation may be performed manually or through specialized software. When do we use Aggregation ?? By reference de-couples the lifetimes of the two objects. Stephen R. Smoot, Nam K. Tan, in Private Cloud Computing, 2012.
