Classification and clustering are two methods of organizing objects into groups based on their features. Classification involves assigning objects to predefined classes based on their attributes, while clustering aims to group similar objects together without predefined labels. Classification uses supervised learning with training data containing class labels, while clustering is unsupervised and does not use pre-labeled data. Different algorithms such as decision trees and Bayesian classifiers are used for classification, while k-means, expectation maximization, and other methods are typically applied to clustering.
Performance Comparision of Machine Learning AlgorithmsDinusha Dilanka
In this paper Compare the performance of two
classification algorithm. I t is useful to differentiate
algorithms based on computational performance rather
than classification accuracy alone. As although
classification accuracy between the algorithms is similar,
computational performance can differ significantly and it
can affect to the final results. So the objective of this paper
is to perform a comparative analysis of two machine
learning algorithms namely, K Nearest neighbor,
classification and Logistic Regression. In this paper it
was considered a large dataset of 7981 data points and 112
features. Then the performance of the above mentioned
machine learning algorithms are examined. In this paper
the processing time and accuracy of the different machine
learning techniques are being estimated by considering the
collected data set, over a 60% for train and remaining
40% for testing. The paper is organized as follows. In
Section I, introduction and background analysis of the

the results of two algorithms. Finally, the paper concludes
with a discussion of future directions for research by
eliminating the problems existing with the current

Harm in homeopathy: Aggravations, adverse drug events or medication errors?home
This study prospectively observed 335 follow-up visits of 181 patients receiving homeopathic treatment between June 2003 and June 2004. The study aimed to assess harm from homeopathic medicines by reporting any adverse drug events. Nine adverse reactions were reported, representing 2.68% of follow-up visits. Most events were minor and transient. One case involved an allergic reaction to lactose, an excipient in the granules. The study concludes that while adverse events to homeopathic drugs do occur, they are rare and not typically severe.
The document discusses frequent pattern mining and the Apriori algorithm. It can be summarized as follows:
1) Frequent pattern mining is used to find patterns that frequently occur together in a transaction database. The Apriori algorithm is an influential algorithm for mining frequent itemsets using an iterative, candidate generation and test approach.
2) The Apriori algorithm generates candidate itemsets of length k from frequent itemsets of length k-1, and then prunes the candidates that have a subset that is infrequent. This is repeated until no further frequent itemsets are found.
3) Once frequent itemsets are discovered, association rules can be generated from them if they satisfy minimum support and confidence thresholds.
This document discusses association analysis and the Apriori algorithm for mining association rules from transactional data. It defines key concepts like support, confidence, and association rules. The Apriori algorithm works in two phases: (1) frequent itemset generation using candidate generation and pruning to iteratively find itemsets that meet a minimum support threshold, and (2) rule generation to extract high-confidence rules from the frequent itemsets. Pruning strategies like the Apriori principle and support-based pruning are used to reduce the search space and make the algorithm efficient for large datasets.

Pattern Discovery Using Apriori and Ch-Search Algorithmijceronline
This document discusses and compares the Apriori and Ch-Search algorithms for pattern discovery in large databases. The Apriori algorithm uses minimum support and confidence thresholds to generate frequent itemsets and association rules, but can miss some "negative" rules. The Ch-Search algorithm uses "coherent rules" based on propositional logic to discover both positive and negative patterns without minimum support thresholds. It is more efficient at pattern discovery than Apriori as it considers all attribute relationships. The proposed system applies the Ch-Search algorithm to generate rules and patterns for classification, demonstrating it can produce more accurate and complete results than Apriori.
IRJET-Comparative Analysis of Apriori and Apriori with Hashing AlgorithmIRJET Journal
This document compares the Apriori and Apriori with hashing algorithms for association rule mining. Association rule mining is used to find frequent itemsets and discover relationships between items in transactional databases. The Apriori algorithm uses a bottom-up approach to generate frequent itemsets by joining candidate itemsets of length k with themselves. The Apriori with hashing algorithm improves efficiency by using a hash table to reduce the candidate itemset size. The document finds that Apriori with hashing outperforms the standard Apriori algorithm on large datasets by taking less time to generate frequent itemsets.
A NEW ASSOCIATION RULE MINING BASED ON FREQUENT ITEM SETcscpconf
In this paper a new mining algorithm is defined based on frequent item set. Apriori Algorithm scans the database every time when it finds the frequent item set so it is very time consuming and at each step it generates candidate item set. So for large databases it takes lots of space to store candidate item set. The defined algorithm scans the database at the start only once and then makes the undirected item set graph. From this graph by considering minimum support it findsthe frequent item set and by considering the minimum confidence it generates the association rule. If database and minimum support is changed, the new algorithm finds the new frequent items by scanning undirected item set graph. That is why it’s executing efficiency is improved distinctly compared to traditional algorithm.
Support measures how frequently item sets appear together in transactions. Confidence indicates how often if-then statements are found to be true. Association rules are useful for analyzing customer behavior patterns and predicting customer purchases. Lift compares the observed response rate for a target group identified by a rule to the average response rate, and is a measure of how effective a rule is at targeting customers. A higher lift indicates the rule is better at identifying customers with an enhanced response.
This document describes a decision support system (DSS) that uses the Apriori algorithm, genetic algorithm, and fuzzy logic to analyze medical data and make accurate diagnostic decisions. The DSS first uses Apriori to extract association rules from pre-processed medical data. It then applies a genetic algorithm to optimize the results and determine optimal attribute values. Finally, it employs fuzzy logic for decision-making based on the optimized attribute values. The authors tested their DSS on diabetes data and found the results to be interesting. Their proposed system aims to help medical professionals make quicker and more accurate diagnostic decisions.

A Survey on Identification of Closed Frequent Item Sets Using Intersecting Al...IOSR Journals
This document summarizes research on using an intersection approach to identify closed frequent item sets from transactional data. It discusses how existing intersection algorithms enumerate and intersect candidate transaction sets or use a cumulative scheme with a repository that new transactions are intersected with. The document also reviews research on reducing the size of prefix trees used to store candidate sets as the number of transactions increases. It aims to draw attention to the intersection approach as a less researched area that could be improved to effectively identify closed frequent item sets from large transactional datasets.
The Apriori algorithm is used to find frequent itemsets and association rules. It works in iterative passes over the transactional database, where it first counts item occurrences to find itemsets that meet a minimum support threshold, and then generates association rules from those frequent itemsets that meet a minimum confidence threshold. The algorithm uses the property that any subset of a frequent itemset must also be frequent. It employs a "join" step to generate candidate itemsets and a "prune" step to remove any candidates where a subset is infrequent, reducing the search space.
The document summarizes research on improving the Apriori algorithm for association rule mining. It first provides background on association rule mining and the standard Apriori algorithm. It then discusses several proposed improvements to Apriori, including reducing the number of database scans, shrinking the candidate itemset size, and using techniques like pruning and hash trees. Finally, it outlines some open challenges for further optimizing association rule mining.
This document summarizes research on improving the Apriori algorithm for mining association rules from transactional databases. It first provides background on association rule mining and describes the basic Apriori algorithm. The Apriori algorithm finds frequent itemsets by multiple passes over the database but has limitations of increased search space and computational costs as the database size increases. The document then reviews research on variations of the Apriori algorithm that aim to reduce the number of database scans, shrink the candidate sets, and facilitate support counting to improve performance.
Introduction to Association Rules.pptxHarsha Patel
The document discusses association rule learning and the Apriori algorithm. It begins by defining association rule learning and its applications, such as market basket analysis. It then explains the key concepts of support, confidence and lift used to measure rule strength. The document proceeds to describe the Apriori algorithm, including its candidate generation and frequent itemset determination steps. An example is provided to demonstrate how the Apriori algorithm is applied to generate association rules from a transactional dataset.
The document discusses the Apriori algorithm for frequent itemset mining. It explains that the Apriori algorithm uses an iterative approach consisting of join and prune steps to discover frequent itemsets that occur together above a minimum support threshold. The algorithm first finds all frequent 1-itemsets, then generates and prunes longer candidate itemsets in each iteration until no further frequent itemsets are found.
This document discusses association rule mining and the Apriori algorithm. Association rule mining seeks to find frequent connections between attributes in transactional data. The Apriori algorithm is commonly used to generate association rules and reduces computation by only considering frequent itemsets that meet a minimum support threshold. Rules are selected based on having sufficient confidence levels. Association rule mining can produce many rules, so care must be taken to identify truly useful patterns and reduce redundancy.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

A SYSTEMATIC RISK ASSESSMENT APPROACH FOR SECURING THE SMART IRRIGATION SYSTEMSIJNSA Journal
The smart irrigation system represents an innovative approach to optimize water usage in agricultural and landscaping practices. The integration of cutting-edge technologies, including sensors, actuators, and data analysis, empowers this system to provide accurate monitoring and control of irrigation processes by leveraging real-time environmental conditions. The main objective of a smart irrigation system is to optimize water efficiency, minimize expenses, and foster the adoption of sustainable water management methods. This paper conducts a systematic risk assessment by exploring the key components/assets and their functionalities in the smart irrigation system. The crucial role of sensors in gathering data on soil moisture, weather patterns, and plant well-being is emphasized in this system. These sensors enable intelligent decision-making in irrigation scheduling and water distribution, leading to enhanced water efficiency and sustainable water management practices. Actuators enable automated control of irrigation devices, ensuring precise and targeted water delivery to plants. Additionally, the paper addresses the potential threat and vulnerabilities associated with smart irrigation systems. It discusses limitations of the system, such as power constraints and computational capabilities, and calculates the potential security risks. The paper suggests possible risk treatment methods for effective secure system operation. In conclusion, the paper emphasizes the significant benefits of implementing smart irrigation systems, including improved water conservation, increased crop yield, and reduced environmental impact. Additionally, based on the security analysis conducted, the paper recommends the implementation of countermeasures and security approaches to address vulnerabilities and ensure the integrity and reliability of the system. By incorporating these measures, smart irrigation technology can revolutionize water management practices in agriculture, promoting sustainability, resource efficiency, and safeguarding against potential security threats.

2. What is Adverse Drug event
????
- Adverse drug event is the result of adverse drug reaction.
- Adverse drug reaction is defined as any undesirable experience associated
with the use of a medical product in a individual.
- In short Adverse drug event is defined as an unwanted or unintended
reaction that results from the normal use of one or more medications
3. Why Adverse Drug Events
happens ???
The adverse drug event have started taking place more frequently and is
increasing because of several reasons like development of new medications,
increase in the use of medications for disease prevention, increased
coverage prescription medications.
4. How can ADEs be prevented
????
If a database of adverse drug events which took place anywhere in the
world is maintained and can be accessed by the authorities ,hospitals ,etc. ,
any possible risks to patient's life can be avoided as we are already aware of
the outcomes.
5. So , How can we help here
????
In this project, we plan on creating an Adverse drug reaction response system
which refers to the analytical tool which will be helping to analyze the
adverse drug reaction triples from the database.
6. What is to be done ??
Firstly the database is maintained using the already existing data or the data
provided by the user via. Interfaces for which we use the client-server
connection. Then, we use Apriori algorithm for mining the data which gives us
the potential drugs or drug pairs or triplets which can result into Adverse Drug
Events which initially starts with a transaction table.
7. Data saved and managed
using client-server
connection.
5 interfaces for entry but one database from which the data is mined.
8. Apriori Algorithm used for
mining data
The Apriori algorithm is a classic algorithm for learning association rules.
Association rule learning is a popular method for discovering relations
between variables in large databases.
10. What is the support ??
The support of an item (or set of items) is the number of transactions in which
that item (or items) occur.
11. What is the support threshold
??
The support threshold is defined by the user and is a number for which the
support for each item (or items) has to be equal or above for the support
threshold to be fulfilled.
Lets say in this example ,the value is 40 %.
12. What is a frequent item set
??
A frequent item set is an item set whose number of occurrences in the
transactions are above the support threshold.
13. Firstly, start with the
transaction database.
Transaction database contains the relationship status of medicines to cases
already present in the database.
14. From where we create a
candidate item set – Pass 1
We basically find the support values for each item i.e. drug in our case.
15. Now we create the frequent
item set – Pass 1
Where we keep the items , i.e. drugs whose support >= threshold support (40%
in this case).
16. Now we find the support
values for drug pairs – Pass 2
Here the item set contains all the possible permutations between the given
items and their support values are found.
17. Then again, we find the
frequent item set for Pass 2
Support >= threshold or min. support , else the item i.e. drug pair is
removed ; which in turn means that the removed pairs are not so
frequent.
18. Now moving on to drug
triplets – Pass 3
- Here, first we combine the elements to get triplets using the frequent item
set from pass 2, where the first element is same.
- Their support value is the min. [support{1st element in the combination from
pass 2), support (2nd element in the combination from pass 3)]
19. For frequent item set ,the sets
are pruned similarly – Pass 3
Support >= threshold or min. support
20. So in this way we find the frequent item set in
each pass and the result can be displayed after
each pass, in accordance to the user
requirements. So the user can see the risk in taking
the drugs as their effect and rest of the related
information is displayed.
21. Pseudo Code :-
Pass 1
1.Generate the candidate itemsets in C1
2.Save the frequent itemsets in L1
3.Pass kGenerate the candidate itemsets in Ck from the frequent
itemsets in Lk-1
1. Join Lk-1 p with Lk-1q, as follows:
insert into Ck
select p.item1, p.item2, . . . , p.itemk-1, q.itemk-1
from Lk-1 p, Lk-1q
where p.item1 = q.item1, . . . p.itemk-2 = q.itemk-2, p.itemk-1 < q.itemk-1
2. Generate all (k-1)-subsets from the candidate itemsets in Ck
3. Prune all candidate itemsets from Ck where some (k-1)-subset of the candidate itemset is not in the frequent itemset Lk-1
4.Scan the transaction database to determine the support for each candidate itemset in Ck
5.Save the frequent itemsets in Lk
22. Pseudo Code (for our project) :-
In pass 1 , Candidate item sets are generated and then frequent item sets are
generated when the support values from candidate item sets are compared
to the specified min. support value which act as a threshold support value
and the items with support value less than this value is removed, which then
leads to pass 2 which uses the frequent item sets from pass 1 to create item
sets of entities pairs where only the elements with support value greater than
specified support value are kept giving us a new frequent item set . Then this
frequent item sets are used in pass 3 where the two elements with first
element same are combined to get triplets and the min. support value of the
taken two frequent set is taken and then compared to the min. specified
support value to get the frequent item sets for pass 3. So, here we can get the
output from all the passes depending upon the user requirements.
