Data mining can be defined as the process of uncovering hidden patterns in random data that are potentially useful. The discovery of interesting association relationships among large amounts of business transactions is currently vital for making appropriate business decisions. Association rule analysis is the task of discovering association rules that occur frequently in a given transaction data set. Its task is to find certain relationships among a set of data (itemset) in the database. It has two measurements: Support and confidence values. Confidence value is a measure of ruleÃ¢â‚¬â„¢s strength, while support value corresponds to statistical significance. There are currently a variety of algorithms to discover association rules. Some of these algorithms depend on the use of minimum support to weed out the uninteresting rules. Other algorithms look for highly correlated items, that is, rules with high confidence. Traditional association rule mining techniques employ predefined support and confidence values. However, specifying minimum support value of the mined rules in advance often leads to either too many or too few rules, which negatively impacts the performance of the overall system. This work proposes a way to efficiently mine association rules over dynamic databases using Dynamic Matrix Apriori technique and Multiple Support Apriori (MSApriori). A modification for Matrix Apriori algorithm to accommodate this modification is proposed. Experiments on large set of data bases have been conducted to validate the proposed framework. The achieved results show that there is a remarkable improvement in the overall performance of the system in terms of run time, the number of generated rules, and number of frequent items used.

Class, I'm providing a recently example of a critical analysis written by Dr. Valorie King. This example is based on the 1st case study for this class, CSIA 350. I think most of you have a good idea of what's required for the case studies, but use the information as you need. I will continue to grade appropriate. A Critical Analysis (CA) is a discussion response that has an introductory paragraph, an analysis section (around 3 paragraphs or so), and a brief summary. For Case Study #1, a really good CA would have looked something like this: There are many reasons why a business should invest in cybersecurity products and services. In [her / his] essay, [student name] addressed ethical principles which drive such investments. While ethics are important, the business needs and requirements for IT security must also be considered. In this critical analysis response, I would like to take a deeper look at three important points which drive businesses to invest in IT security. First, consider the question of the Business Benefits of IT Security products and services. Businesses exist to make a profit (Vitez, 2016). Making a profit requires that losses and unnecessary costs be avoided. This is where the business benefit of IT security products comes into play. An anti-virus product can prevent a malware infection (Drew, 2011). Spending some money to buy an anti-virus product to prevent malware will save money in the long run since the business will not have to pay to cleanup malware infections on laptops, workstations, and servers. Second, consider the question of Why an organization should invest in IT security technologies. This is very similar to the first question. But, in addition to the financial benefits (cost avoidance) there are also legal and regulatory reasons why an organization should invest in IT security technologies (Smedinghoff, 2005). Many laws require that companies use encryption to protect private information (HIPAA, FERPA, etc.). This is an IT security technology that a company may be legally required to purchase (invest in). Third, consider Where an organization should focus its attention & why. Technology is only one type of investment that a company should make when it comes to IT security. Investing in people by hiring well qualified security professionals and then providing ongoing training is another area where a company needs to spend money to protect information, information systems, and information infrastructures (ISACA, 2009). Even the best IT security products need people who understand how to configure, test, and operate those products. For this reason, an organization should also focus its attention on hiring the best security professionals that it can afford. Then, the company should keep these people the best by investing in training. In summary, there are many reasons why a business should invest in IT security and why those investments should include both people and products (technologies). But, the b ...

Data mining is the novel technology of discovering the important information from the data repository which is widely used in almost all fields Recently, mining of databases is very essential because of growing amount of data due to its wide applicability in retail industries in improving marketing strategies. Analysis of past transaction data can provide very valuable information on customer behavior and business decisions. The amount of data stored grows twice as fast as the speed of the fastest processor available to analyze it.Its main purpose is to find the association relationship among the large number of database items. It is used to describe the patterns of customers purchase in the supermarket. This is presented in this paper. Rajeshri Shelke"Data Mining For Supermarket Sale Analysis Using Association Rule" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-1 | Issue-4 , June 2017, URL: http://www.ijtsrd.com/papers/ijtsrd94.pdf http://www.ijtsrd.com/engineering/computer-engineering/94/data-mining-for-supermarket-sale-analysis-using-association-rule/rajeshri-shelke

Data Mining For Supermarket Sale Analysis Using Association Rule

Association rules in data mining are useful for the analysis and prediction of an individual user’s behavior which facilitates the data analysis on a regular basis for market basket data, clustering of products, designing catalogs and playing an immense role for store layout setting. This paper presents a successor of the Apriori and variation of the CHARM algorithm, which is the MG-CHARM algorithm that is used for finding relationships between certain attributes instead of the whole dataset. The MG-CHARM algorithm is an Association Rule Mining (ARM) algorithm that is used to select the target database which in turn takes less time to find the desired association rules. In the proposed implementation, the actions performed by a user will be effectively recorded in the target database. The datasets that are generated will have to be fed to the semi - automated, adaptive software which will fetch the output based on ARM algorithm. The algorithm will determine the relations for different datasets by mining Minimal Generators (mGs) from Frequently Closed Itemsets (FCI’s) to carry out decision making and pattern analysis of the Itemsets.

This research paper proposes an algorithm to find association rules for incremental databases. Most of the transaction databases are often dynamic. Suppose consider super market customers daily purchase transactions. Day to day customer’s behaviour to purchase items may change and new products replace old products. In this scenario static data mining algorithms doesn't make good significance. If an algorithm continuously learns day to day, then we can get most updated knowledge. This is very much helpful in present fast updating world. Famous and benchmarked algorithms for Association rules mining are Apriory and FP- Growth. However, the major drawback in Appriory and FP-Growth is, they must be rebuilt all over again once the original database is changed. Therefore, in this paper we introduce an efficient algorithm called Binary Decision Tree (BDT) to process incremental data. To process continuously data we need so much of processing and storage resources. In this algorithm we scan data base only once by which we construct dynamic growing binary tree to find association rules with better performance and optimum storage. We can apply for static data also, but our main intension is to give optimum solution for incremental data.

This paper presents a new approach based on genetic algorithms (GAs) to generate maximal frequent itemsets (MFIs) from large datasets. This new algorithm, GeneticMax, is heuristic which mimics natural selection approaches for finding MFIs in an efficient way. The search strategy of this algorithm uses a lexicographic tree that avoids level by level searching which reduces the time required to mine the MFIs in a linear way. Our implementation of the search strategy includes bitmap representation of the nodes in a lexicographic tree and identifying frequent itemsets (FIs) from superset-subset relationships of nodes. This new algorithm uses the principles of GAs to perform global searches. The time complexity is less than many of the other algorithms since it uses a non-deterministic approach. We separate the effect of each step of this algorithm by experimental analysis on real datasets such as Tic-Tac-Toe, Zoo, and a 10000×8 dataset. Our experimental results showed that this approach is efficient and scalable for different sizes of itemsets. It accesses a major dataset to calculate a support value for fewer number of nodes to find the FIs even when the search space is very large, dramatically reducing the search time. The proposed algorithm shows how evolutionary method can be used on real datasets to find all the MFIs in an efficient way.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

Retrieval augmented generation (RAG) is the most popular style of large language model application to emerge from 2023. The most basic style of RAG works by vectorizing your data and injecting it into a vector database like Milvus for retrieval to augment the text output generated by an LLM. This is just the beginning. One of the ways that we can extend RAG, and extend AI, is through multilingual use cases. Typical RAG is done in English using embedding models that are trained in English. In this talk, we’ll explore how RAG could work in languages other than English. We’ll explore French, Chinese, and Polish.

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
