Face Recognition System using Self Organizing Feature Map and Appearance Base...ijtsrd
Face Recognition has develop one of the most effective presentations of image analysis. This area of research is important not only for the applications in human computer interaction, biometric and security but also in other pattern classification problem. To improve face recognition in this system, two methods are used PCA Principal component analysis and SOM Self organizing feature Map .PCA is a subspace projection method is used compress the input face image. SOM method is used to classify DCT based feature vectors into groups to identify if the subject in the input image is "present" or "not present" in the image database. The aim of this system is that input image has to compare with stored images in the database using PCA and SOM method. An image database of 100 face images is evaluated containing 10 subjects and each subject having 10 images with different facial expression. This system is evaluated by measuring the accuracy of recognition rate. This system has been implemented by MATLAB programming.

DYNAMIC NETWORK ANOMALY INTRUSION DETECTION USING MODIFIED SOMcscpconf
Detection of unexpected and emerging new threats has become a necessity for secured internet
communication with absolute data confidentiality, integrity and availability. Design and
development of such a detection system shall not only be new, accurate and fast but also
effective in a dynamic environment encompassing the surrounding network. In this paper, an algorithm is proposed for anomaly detection through modifying the Self – Organizing Map (SOM), by including new neighbourhood updating rules and learning rate dynamically in order to overcome the fixed architecture and random weight vector assignment. The algorithm initially starts with null network and grows with the original data space as initial weight vectors. New nodes are created using distance threshold parameter and their neighbourhood is identified using connection strength. Employing learning rule, the weight vector updation is carried out for neighbourhood nodes. Performance of the new algorithm is evaluated for using standard bench mark dataset. The result is compared with other neural network methods, shows 98% detection rate and 2% false alarm rate.
National Flags Recognition Based on Principal Component Analysisijtsrd
Recognizing an unknown flag in a scene is challenging due to the diversity of the data and to the complexity of the identification process. And flags are associated with geographical regions, countries and nations. But flag identification of different countries is a challenging and difficult task. Recognition of an unknown flag image in a scene is challenging due to the diversity of the data and to the complexity of the identification process. The aim of the study is to propose a feature extraction based recognition system for Myanmar's national flag. Image features are acquired from the region and state of flags which are identified by using principal component analysis PCA . PCA is a statistical approach used for reducing the number of features in National flags recognition system.

With the increase in Internet users the number of malicious users are also growing day-by-day posing a
serious problem in distinguishing between normal and abnormal behavior of users in the network. This
has led to the research area of intrusion detection which essentially analyzes the network traffic and tries
to determine normal and abnormal patterns of behavior.In this paper, we have analyzed the standard
NSL-KDD intrusion dataset using some neural network based techniques for predicting possible
intrusions. Four most effective classification methods, namely, Radial Basis Function Network, Self-
Organizing Map, Sequential Minimal Optimization, and Projective Adaptive Resonance Theory have been
applied. In order to enhance the performance of the classifiers, three entropy based feature selection
methods have been applied as preprocessing of data. Performances of different combinations of classifiers
and attribute reduction methods have also been compared.
APPLICATION OF IMAGE FUSION FOR ENHANCING THE QUALITY OF AN IMAGEcscpconf
Advances in technology have brought about extensive research in the field of image fusion.
Image fusion is one of the most researched challenges of Face Recognition. Face Recognition
(FR) is the process by which the brain and mind understand, interpret and identify or verify
human faces.. Image fusion is the combination of two or more source images which vary in
resolution, instrument modality, or image capture technique into a single composite
representation. Thus, the source images are complementary in many ways, with no one input
image being an adequate data representation of the scene. Therefore, the goal of an image
fusion algorithm is to integrate the redundant and complementary information obtained from
the source images in order to form a new image which provides a better description of the scene
for human or machine perception. In this paper we have proposed a novel approach of pixel
level image fusion using PCA that will remove the image blurredness in two images and
reconstruct a new de-blurred fused image. The proposed approach is based on the calculation
of Eigen faces with Principal Component Analysis (PCA). Principal Component Analysis (PCA)
has been most widely used method for dimensionality reduction and feature extraction

In recent machine learning community, there is a trend of constructing a linear logarithm version of
nonlinear version through the ‘kernel method’ for example kernel principal component analysis, kernel
fisher discriminant analysis, support Vector Machines (SVMs), and the current kernel clustering
algorithms. Typically, in unsupervised methods of clustering algorithms utilizing kernel method, a
nonlinear mapping is operated initially in order to map the data into a much higher space feature, and then
clustering is executed. A hitch of these kernel clustering algorithms is that the clustering prototype resides
in increased features specs of dimensions and therefore lack intuitive and clear descriptions without
utilizing added approximation of projection from the specs to the data as executed in the literature
presented. This paper aims to utilize the ‘kernel method’, a novel clustering algorithm, founded on the
conventional fuzzy clustering algorithm (FCM) is anticipated and known as kernel fuzzy c-means algorithm
(KFCM). This method embraces a novel kernel-induced metric in the space of data in order to interchange
the novel Euclidean matric norm in cluster prototype and fuzzy clustering algorithm still reside in the space
of data so that the results of clustering could be interpreted and reformulated in the spaces which are
original. This property is used for clustering incomplete data. Execution on supposed data illustrate that
KFCM has improved performance of clustering and stout as compare to other transformations of FCM for
clustering incomplete data.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

9. Unit Unit, also called artificial particle and agent, is a special type of data point. The difference between unit and the regular data points is that the units are dynamic
10. Competitive learning the position of the unit for each data point can be expressed as follows: p(t+1) = a(p(t)-x)d(p(t),x) a is a factor called learning rate. d(p,x) is a distance scaling function. p x
12. The Self-Organizing Map (SOM) SOM is based on competitive learning. The difference is units are all interconnected in a grid.
13. The Self-Organizing Map (SOM) The unit closet to the input vector is call Best Matching Unit (BMU). The BMU and other units will adjust its position toward the input vector. The update formula is Wv(t + 1) = Wv(t) + Θ (v, t) α(t)(D(t) - Wv(t))
14. The Self-Organizing Map (SOM) Wv(t + 1) = Wv(t) + Θ (v, t)α(t)(D(t) - Wv(t)) Wv(t) = weight vector α(t) = monotonically decreasing learning coefficient D(t) = the input vector Θ (v, t) = neighborhood function This process is repeated for each input vector for a (usually large) number of cycles λ.
