Neural network, also known as a parallel dispersed processing network, is a computing paradigm that is freely modeled after cortical structures of the brain. It consists of consistent processing elements called nodes or neurons that work together to create an output function. The output of a neural network relies on the collaboration of the individual neurons within the network to operate. Processing of information by neural networks is typically done in parallel rather than in series (or sequentially) as in earlier binary computers or Von Neumann machines. Since it relies on its member neurons together to perform its function, a unique property of a neural network is that it can still achieve its overall function even if some of the neurons are not functioning. In other words it is robust to tolerate error or failure. (see fault tolerant) Additionally, neural networks are more readily adaptable to fuzzy logic computing tasks than are Von Neumann machines.

Traditionally, the term neural network has been used to refer to a network of biological neurons. In modern usage, the term is often used to refer to artificial neural networks, which are collected artificial neurons or nodes. Thus the term 'Neural Network' has two distinct connotations:

* Biological neural networks are made up of actual biological neurons that are associated or functionally-related in the peripheral nervous system or the central nervous system

* Artificial neural networks are made up of interconnecting artificial neurons (usually simplified neurons) designed to model (or mimic) some properties of biological neural networks.

Orchids (Orchidaceae family) are among the biggest and most diverse of the flowering plant (angiospermae) families, with over 800 described genera and 25,000 (some sources give 30,000) species, and another 100,000 + hybrids and cultivars formed by horticulturalists. The Kew World Checklist of Orchids includes about 24,000 conventional species. As regards 800 new species are added each year. Orchids, through their floral complexity and their connections with pollinators and their symbiosis with mycorrhizae, are considered by some, along with the grasses, to be examples of the most difficult floral evolution known.

Pruning in landscaping and farming is the practice of removing contaminated, non-productive, or otherwise unwanted portions from a plant. The reason of pruning is to shape the plant by controlling or directing plant growth, to maintain the health of the plant, or to increase the yield or quality of flowers and fruits. Proper pruning is as much a ability as it is an art, since badly pruned plants can become unhealthy or grow in undesirable ways.
