Radial-basis function (RBF) networks
RBF = radial-basis function: là hàm phụ
thuộc vào khỏang cách gốc từ một vector. RBFs là các hàm có dạng như trong hình
Với f là hàm activation phi tuyến, x là các đầu vào và ti là
vị trí thứ i, mẫu đầu tiên, vector cơ sở hoặc vector trung
Điều này chỉ ra các điểm gần tâm sẽ có đầu ra tương tự
Network management is the poor cousin of network design and implementation.
All too often it is treated as an inconvenience by equipment manufacturers, or
forgotten entirely. But the ability to manage network devices is fundamental to
their utility, and a successful and functional network can only be built from equipment
that can be easily managed and operated.
Management refers to the ability to confi gure, control, operate, and diagnose
equipment. Of course, no vendor ships devices that cannot be managed, but
typically each is operated and controlled in a different way.

Perl provides direct access to the C library routines for
socket communication. Often, arguments and return
values are constants defined in the C header files, or
are data structures which Perl will pass in a packed
The Socket module provides these constants and also
many functions for packing and unpacking these data
Ebook "Network security technologies" presents key security technologies from diverse fields, using a hierarchical framework that enables understanding of security components, how they relate to one another, and how they interwork. This text is unique in that it classifies technologies as basic, enhanced, integrated, and architectural as a means of associating their functional complexities, providing added insight into their interrelationships. It introduces and details security components and their relationships to each other.
The Open Systems Interconnection (OSI) model is a reference tool for understanding data communications between any two networked systems. It divides the communications processes into seven layers. Each layer both performs specific functions to support the layers above it and offers services to the layers below it. The
three lowest layers focus on passing traffic through the network to an end system. The top four layers come into play in the end system to complete the process.
This Solution Reference Network Design (SRND) publication is intended to provide a set of guidelines
for designing, implementing, and deploying Voice and Video Enabled IPSec VPN (V3
This SRND defines the comprehensive functional components required to build a Site-to-Site Enterprise
Virtual Private Network (VPN) solution that can transport IP telephony and video.
Your role as a Cisco Certified Design Associate is to be a network design consultant. You will act like
an architect, building comprehensive designs that solve your customer's internetworking problems and
provide the required functionality, performance, and scalability. In the same way that an architect
designs a building or house for a client, you will develop blueprints for an overall internetwork
design, as well as components plans for various pieces of the internetwork.
Describe the structure of a network, including the devices and media that are necessary for successful communications. Explain the function of protocols in network communications. Explain the advantages of using a layered model to describe network functionality. Describe the role of each layer in two recognized network models: The TCP/IP model and the OSI model. Describe the importance of addressing and naming schemes in network communications.
Communicating Over the Network. In this course, we focus on these aspects of the information network:
Devices that make up the network,
Media that connect the devices,
Messages that are carried across the network,
Rules and processes that govern network communications,
Tools and commands for constructing and maintaining networks.
OSI Transport Layer.
In this chapter, we examine the role of the Transport layer. The Transport layer also encompasses these functions: Enables multiple applications to communicate over the network at the same time on a single device. Ensures that, if required, all the data is received reliably and in order by the correct application. Employs error handling mechanisms. Learning Objectives–Upon completion of this chapter, you will be able to: Explain the need for the Transport layer.
This lab will help to develop a better understanding of the seven layers of the OSI model. Specifically
as they relate to the most popular functioning networking model in existence, the TCP/IP model. The
Internet is based on TCP/IP. TCP/IP has become the standard language of networking. However,
the seven layers of the OSI model are the ones most commonly used to describe and compare
networking software and hardware from various vendors. It is very important to know both models
and be able to relate or map the layers of one to the other.
Application Layer Functionality and Protocols. In this chapter, you will learn to:
Describe how the functions of the three upper OSI model layers provide network services to end user applications.
Describe how the TCP/IP Application Layer protocols provide the services specified by the upper layers of the OSI model.
Define how people use the Application Layer to communicate across the information network.
Describe the function of well-known TCP/IP applications, such as the World Wide Web and email, and their related services (HTTP, DNS, SMB, DHCP, SMTP/POP, and Telnet)....
A computer network is the infrastructure that allows two or more computers (called
hosts) to communicate with each other. The network achieves this by providing a set
of rules for communication, called protocols, which should be observed by all
participating hosts. The need for a protocol should be obvious: it allows different
computers from different vendors and with different operating characteristics to
‘speak the same language’.
This chapter introduces the fundamental concepts of computer networks.
This thesis examines how artificial neural networks can benefit a large vocabulary, speaker
independent, continuous speech recognition system. Currently, most speech recognition
systems are based on hidden Markov models (HMMs), a statistical framework that supports
both acoustic and temporal modeling. Despite their state-of-the-art performance, HMMs
make a number of suboptimal modeling assumptions that limit their potential effectiveness.
This document provides design guidance for enterprises that want to provide Internet and limited
corporate access for their guests and partners. Several solutions for guest and partner access challenges
are proposed and analyzed in this document, at both the architectural and functional levels.
The purpose of Top-Down Network Design, Third Edition, is to help you design networks that meet a customer’s business and technical goals. Whether your customer is another department within your own company or an external client, this book provides you with tested processes and tools to help you understand traffic flow, protocol behavior, and internetworking technologies.
This document provides network architects with a general understanding of how to leverage network
virtualization to make a centralized NAC Appliance deployment easier. This document allows the
network architect to select a design and reference the specific implementation details in the associated
design guides. The foundation technologies associated with enterprise network virtualization
architecture are divided into the following three functional areas:
• Access control
• Path isolation
• Services edge...
