title: Proceedings AI/ML for Cybersecurity: Challenges, Solutions, and Novel Ideas at SIAM Data Mining 2021
abstract: Malicious cyber activity is ubiquitous and its harmful effects have dramatic and often irreversible impacts on society. Given the shortage of cybersecurity professionals, the ever evolving adversary, the massive amounts of data which could contain evidence of an attack, and the speed at which defensive actions must be taken, innovations which enable autonomy in cybersecurity must continue to expand, in order to move away from a reactive defense posture and towards a more proactive one. The challenges in this space are quite different from those associated with applying AI in other domains such as computer vision. The environment suffers from an incredibly high degree of uncertainty, stemming from the intractability of ingesting all the available data, as well as the possibility that malicious actors are manipulating the data. Another unique challenge in this space is the dynamism of the adversary causes the indicators of compromise to change frequently and without warning. In spite of these challenges, machine learning has been applied to this domain and has achieved some success in the realm of detection. While this aspect of the problem is far from solved, a growing part of the commercial sector is providing ML enhanced capabilities as a service. Many of these entities also provide platforms which facilitate the deployment of these automated solutions. Academic research in this space is growing and continues to influence current solutions, as well as strengthen foundational knowledge which will make autonomous agents in this space a possibility.

title: Analysis on Telemarketing Access System Based on C/S Architecture and Data Mining
abstract: With the rapid development of information science, the smart system is becoming popular. Hence, this paper conducts the analysis on the telemarketing access system based on C/S architecture and data mining. B/S is far inferior to C/S. Taken together, it can be found that all the strengths of the C/S are the weaknesses of B/S, and vice versa. By using this advantage, the analysis on the CMS is considered. After the OSS processing is successfully returned, the CMS triggers the CDN process, and the CDN process first goes to the CMM. The systematic design shows the robustness of the model.

title: Research on Application of Online Teaching Performance Prediction Based on Data Mining Algorithm
abstract: The application of data mining in teaching has entered the stage of development. During the epidemic, colleges and universities have accumulated a large amount of online teaching statistical data. These data can be used to establish a classification model for predicting student performance. In this paper, the Naive Bayes algorithm is improved to solve the problem of underflow when the data feature values are too large. The student performance prediction classification model is constructed, and the classification efficiency and accuracy are improved to a certain extent. The improved model is used to predict and warn the performance in the mid term stage to prevent The phenomenon of a large proportion of missing subjects, thereby ensuring the quality of students' learning throughout the semester.

title: Data Mining Classification and analytical model of prediction for Job Placements using Fuzzy Logic
abstract: One of the most common issues that new graduates experience is the insufficient understanding of basic concepts. Major skill gaps in this area include a lack of deep comprehension on technical information, lack of customer management abilities, and insufficient knowledge of numerous disciplines. The study has attributed a lack of English communication skills, which they found in 73.63% of applicants, and poor analytical and quantitative skills, which they found in 57.96% of applicants, as a major cause of unemployment. Aptitude tests are conducted to analyze the problem solving skills of the candidate; this evaluation helps to solve a problem at a given point in time. The proposed study has collected data on students, who had different information about their previous and current academic records, and then different classification algorithms along with the Data Mining Tool (VEKA) are used to analyze academic performance in training and accommodation. This study presents a proposed model based on a classification approach to find a better evaluation method in order to predict the student accommodation. There are many basic classification algorithms and statistical methods that can be used as good resources for classifying student datasets in education. In this article, a fuzzy inference system was used to predict the student performance and improve academic performance. This model can determine the relationship between student achievement and campus placement.
