  Neural networks
The network learns by adjusting the weights based on comparing the output unit activation levels to the correct level as determined by the user's indication of which letter he drew.
Unsupervised learning: the network learns to classify input patterns into categories based on similarity, with no explicit feedback from a teacher as to which category an item belongs to or whether a given classification is correct.
The network learning algorithms we have considered thus far have all been examples of supervised learning - the network is taught by a teacher who knows the correct output for each input pattern to be presented.

 Network transparency: Just the facts...   (Site not responding. Last check: 2007-10-15)
This kind of transparency (The quality of being clear and transparent) is referred to as network transparency or distribution transparency.
Location transparency in commands used to perform a task is independent both of the locations of the data, and the system on which an operation is carried out.
Naming transparency means that a unique name is provided for each object in the database.

 [No title]
Since lower-level network resources are shared among many different users with different applications, the complexity of potential interactions among independent users rises with the complexity of the behaviors that the users or applications can request.
To maintain the largest degree of network transparency, then, the end-to-end principle requires that the semantics of any active features be carefully constrained so that interactions among different users of a shared lower level can be predicted by a designer who is using the services and functions of that active layer.
Thus, even though active network ideas are not ruled out by end-to-end arguments, we have not seen practical, high-impact examples of a sufficiently simple, flexible, and transparent programming semantics suitable for use in lower levels of networks.

 Network Transparent languages | Lambda the Ultimate
Are there any network transparent languages apart from Mozart(Oz) and Google's Sawzall(to some extent).I have tried searching on this subject, but nothing significant turned up.I have not even found any references to such languages in any of the programming language (text) books.
It is transparent (since running in one process has the same language semantics as running in many) and it gives a good solution both for partial failure and for latency.
Network transparency implies the code runs the same, unchanged, no matter where it is, and/or where it's other (sub)?elements of it are running.

 RFC 2956 (rfc2956) - Overview of 1999 IAB Network Layer Workshop
The goal of the workshop was to discuss the current state of the Network Layer and the impact various currently deployed or future mechanisms and technologies might have on the continued growth and usage of the Internet.
There are multiple causes for the loss of transparency, for example the deployment of network address translation devices, the use of private addresses, firewalls and application level gateways, proxies and caches.
Increased deployment causes a further decline of network transparency and this inhibits the deployment of new applications.

 RFC 2775 (rfc2775) - Internet Transparency
This document was used as input to the IAB workshop on the future of the network layer held in July 1999.
The causes of this loss of transparency are partly artefacts of parsimonious allocation of the limited address space available to IPv4, and partly the result of broader issues resulting from the widespread use of TCP/IP technology by businesses and consumers.
The current network level security model [RFC 2401] was constructed prior to the recognition that end- to-end address transparency was under severe threat.

 Operation and Maintenance for an All-Optical Transport Network
This network enhancement provides a lot of benefits for network operators and users, such as efficient transport and routing of multigigabit streams, simple network adaptation to new or changing requirements, evolution from today s transport network, and reuse of existing infrastructure.
It should be noted that even in a transparent network there are restrictions on the physical parameters of the signal offered by the source (i.e., input power, optical frequency, or bandwidth cannot be arbitrary).
At this point the intended transparency of the optical network may cause some difficulty because the regenerator section AIS the optical path layer has to provide is dependent on the client.

 World First Wireless Optimizer Technology From Exinda
In Australia, wireless networks are becoming commonplace in offices as an alternative to inflexible hardwired data cabling.
Wireless networking is frequently slower than cable because, until now, it has been impossible to identify problems in a radio frequency-based network.
WRS allows an IT department to track the network efficiency of a wireless network as well as track users (including hackers) and ensure optimum operation of the network by identifying problems such as software conflicts and inefficiencies.

 IBM Research | Technical Paper Search | Network Transparency: The plaNET Approach   (Site not responding. Last check: 2007-10-15)
The successful deployment of such networks will clearly depend on a wide range of factors such as cost and technology, but we believe that foremost among all is how well they will support existing and future {\em applications.} Emphasizing an application oriented perspective is one of the main motivation of this paper.
We denote by {\em ``transparency''} the ability of a network to transport application information while altering or manipulating it as little as possible, and we believe it will be key to the acceptance of high-speed networks.
In particular, we argue that a ``transparent'' data transfer mechanism can be provided that is both compatible with current standard proposals such as ATM and Frame Relay, and offers applications the choice of the data transfer mode that best meet their needs.

 RFC2775
Another aspect, in which the behaviour of the network and that of the end-systems interact in a complex way, is performance, in a generalised sense.
When the catenet concept (a network of networks) was first described by Cerf in 1978 [IEN 48] following an earlier suggestion by Pouzin in 1974 [CATENET], a clear assumption was that a single logical address space would cover the whole catenet (or Internet as we now know it).
Network address translators (NATs) are an almost inevitable consequence of the existence of Intranets using private addresses yet needing to communicate with the Internet at large.

Network operating systems are designed to support communication and resource sharing between nodes in a distributed system.
A network OS doesn’t try to hide the fact that there are multiple separate computers in the system; e.g., a user who wanted to run a process at another location would have to specifically request permission to do so.
Transparency: the property of hiding low-level details from users (making them “invisible”); thus providing a logical view of the system that doesn’t necessarily reflect what the system actually is like.

 RFC2956
By the notion "deployment of end to end transport" it is meant that it is a goal to be able to deploy new applications that span from any host to any other host without intermediaries, and this requires transport protocols with similar span (see also [1]).
In the discussions transparency was referred to as the original Internet concept of a single universal logical addressing scheme and the mechanisms by which packets may flow from source to destination essentially unaltered [1].
Operational stability of DNS is paramount, especially during a transition of the network layer, and both IPv6 and some network address translation techniques place a heavier burden on DNS.
