Email: solutions altexsoft. Streaming services like Netflix, Prime, and Spotify bring it right into your device in a split second. So, what has changed? Streaming services made it possible for us to consume content continuously without uploading the whole file. Such a method requires sending and receiving millions of bits of data at any given moment, so that you can play another Black Mirror episode on the go.
Due to its similar behavior to a physical jet of water, continuous transition of data was named streaming , and now it exists in different forms. With the growth of internet-of-things IoT devices, overall data volume increased, and engineering advancements in this field led to new ways of collecting, processing, and analyzing data. As a result, it became possible to provide real-time analytics by processing streamed data.

Data stream mining is a strategy that involves identifying and extracting information from an active data stream. With this approach, the idea is to pull the data without creating any type of interruption in the stream itself, making it possible for others to also make use of the data even as the extraction is taking place.
This type of data stream mining effort can involve all sorts of data, ranging from voice to video transmission over the Internet and even to day to day tasks like withdrawing money from a bank account using an automated teller machine or holding a telephone conversation. One of the characteristics of data stream mining is the ability to accurately project or predict how to locate the information desired and what type of knowledge discovery tools will aid in locating and successfully extracting the desired information.
For example, when a customer initiates a transaction using an automated teller machine, the programming for the machine initiates a search for relevant account information, locates the data and then determines if the amount of the transaction will reduce the account balance below an allowable amount, based on the way the account is structured.
From there, the programming can return relevant data to the user, such as documenting the successful completion of the requested transaction and providing the account balance remaining after the credit or debit involved with the transaction is recorded. Another common example of data stream mining is the basic web search using a browser. With this application, the end user enters search values into a field, and the software that drives the browser seeks to interpret those values and return data that has some relevance to the search criteria.
Once the user has settled on the search phrase, the browser returns results in order of ranking, using algorithms that are relevant to the configuration of the browser itself. One of the chief benefits of data stream mining is the ability to access and search data without actually prohibiting others to make use of that same data.

Data Stream Mining also known as stream learning is the process of extracting knowledge structures from continuous, rapid data records. A data stream is an ordered sequence of instances that in many applications of data stream mining can be read only once or a small number of times using limited computing and storage capabilities.
In many data stream mining applications, the goal is to predict the class or value of new instances in the data stream given some knowledge about the class membership or values of previous instances in the data stream. Often, concepts from the field of incremental learning are applied to cope with structural changes, on-line learning and real-time demands.
In many applications, especially operating within non-stationary environments, the distribution underlying the instances or the rules underlying their labeling may change over time, i. Detecting concept drift is a central issue to data stream mining. Examples of data streams include computer network traffic, phone conversations, ATM transactions, web searches, and sensor data. Data stream mining can be considered a subfield of data mining , machine learning , and knowledge discovery.

Sign in. Imagine a factory with sensors capturing 10 KB of information every second, in one hour is captured nearby 36 GB of information and GB daily. This massive information needs to be analysed in real time or in the shortest time possible to detect irregularities or deviations in the system and quickly react. Stream Mining enables to analyse large amounts of data in real-time.
Stream Mining enables the analysis of massive quantities of data in real time using bounded resources. Data Stream Mining is t he process of extracting knowledge from continuous rapid data records which comes to the system in a stream. A Data Stream is an ordered sequence of instances in time [1,2,4]. Data Stream Mining fulfil the following characteristics:. Next, is discussed how to analyse Data Streams.
Data-Based Techniques rely on analysing a representative subset of data [3, 9]. This techniques also are used as preprocessing for Data Stream algorithms. On the Other Hand, Mining Techniques are enhanced versions of traditional Data Mining Algorithms.

DASFAA : Database Systems for Advanced Applications pp Cite as. Data streams are continuous flows of data. Examples of data streams include network traffic, sensor data, call center records and so on. Their sheer volume and speed pose a great challenge for the data mining community to mine them. Data streams demonstrate several unique properties: infinite length, concept-drift, concept-evolution, feature-evolution and limited labeled data.
Concept-drift occurs in data streams when the underlying concept of data changes over time. Concept-evolution occurs when new classes evolve in streams. Feature-evolution occurs when feature set varies with time in data streams. Data streams also suffer from scarcity of labeled data since it is not possible to manually label all the data points in the stream. Each of these properties adds a challenge to data stream mining.
Multi-step methodologies and techniques, and multi-scan algorithms, suitable for knowledge discovery and data mining, cannot be readily applied to data streams. In spite of the success and extensive studies of stream mining techniques, there is no single tutorial dedicated to a unified study of the new challenges introduced by evolving stream data like change detection, novelty detection, and feature evolution. This tutorial presents an organized picture on how to handle various data mining techniques in data streams: in particular, how to handle classification and clustering in evolving data streams by addressing these challenges.
The importance and significance of research in data stream mining has been manifested in most recent launch of large scale stream processing prototype in many important application areas.

Mining and analysing streaming data is crucial for many applications, and this area of research has gained extensive attention over the past decade. However, there are several inherent problems that continue to challenge the hardware and the state-of-the art algorithmic solutions. Examples of such problems include the unbound size, varying speed and unknown data characteristics of arriving instances from a data stream.
The aim of this research is to portray key challenges faced by algorithmic solutions for stream mining, particularly focusing on the prevalent issue of concept drift. A comprehensive discussion of concept drift and its inherent data challenges in the context of stream mining is presented, as is a critical, in-depth review of relevant literature.
Current issues with the evaluative procedure for concept drift detectors is also explored, highlighting problems such as a lack of established base datasets and the impact of temporal dependence on concept drift detection. By exposing gaps in the current literature, this study suggests recommendations for future research which should aid in the progression of stream mining and concept drift detection algorithms. The global datasphere is a notional environment in which data produced worldwide is contained.
According to Reinsel et al. Its growth is expected to continue rapidly, and by it is hypothesised to contain ZB of data. Such exponential growth is due, in part, to hardware developments and an increase in user availability and accessibility. Data is now generated at a near constant and limitless rate, resulting from an array of devices, networks and everyday tasks such as credit card transactions and mobile phones [ 1 ].

Securing advanced metering infrastructure using intrusion detection system with data stream mining. ABSTRACT Advanced metering infrastructure AMI is an imperative component of the smart grid, as it is responsible for collecting, measuring, analyzing energy usage data, and transmitting these data to the data concentrator and then to a ABSTRACT Advanced metering infrastructure AMI is an imperative component of the smart grid, as it is responsible for collecting, measuring, analyzing energy usage data, and transmitting these data to the data concentrator and then to a central system in the utility side.
Therefore, the security of AMI is one of the most demanding issues in the smart grid implementation. In this paper, we propose an intrusion detection system IDS architecture for AMI which will act as a complimentary with other security measures. This IDS architecture consists of three local IDSs placed in smart meters, data concentrators, and central system AMI headend.
For detecting anomaly, we use data stream mining approach on the public KDD CUP data set for analysis the requirement of the three components in AMI.
