TAgentic AIOps for Resilient Enterprise Operations: A Closed-Loop, Evidence-Aware Architecture for Incident Triage, RCA, and SLO Governance

Abhradeep Chatterjee, NTT DATA Services, United States

ABSTRACT

Modern enterprise operations face a compounding failure surface created by microservices sprawl, hybrid cloud dependencies, and continuous delivery. Traditional AIOps pipelines detect anomalies but often stop short of trustworthy, auditable actions, leaving the highest-cost minutes of an incident—triage, correlation, and root-cause analysis—largely manual. This paper presents an agentic, closed-loop AIOps architecture that couples event intelligence with evidence-aware reasoning, policy-guarded action execution, and continuous learning from outcomes. The design unifies multi-source telemetry ingestion, causal-graph correlation, retrieval-augmented runbook planning, risk-scored remediation with human-in-the-loop controls, and SLO-governed feedback. We define an evaluation protocol spanning detection quality, diagnostic latency, action safety, and operator load, and provide a simulation harness to compare alerting, classic AIOps, and agentic AIOps. Simulation results across three scenarios show improved triage and mitigation speed while keeping unsafe actions near-zero via policy gating.

ABSTRACT

The medical datasets are often confronted with the problems of class imbalance and redundancy of the features, which could affect the quality of classification prediction. In this study, the performance of four approaches to the Synthetic Minority Oversampling Technique (SMOTE)—SMOTE-ENN, Borderline SMOTE, ADASYN, and SMOTE-Tomek Links—has been studied together with feature selection and the XGBoost classifier in order to predict breast cancer and heart disease. The used datasets were processed to exclude noises, to make the distribution even, and to select the most important features. The analysis of the model has been conducted based on several criteria, such as accuracy, precision, recall, F1-score, and Cohens Kappa. For the heart disease data, the best results were obtained for the SMOTE-ENN approach, with accuracy, recall, and F1-score equal to 56.15%, 44.50%, and 27.46% correspondingly, that allowed detecting minority class cases. At the same time, for the breast cancer data, all other approaches provided better results, including accuracy, recall, F1-score, and Kappa of 96.49%, 100%, 97.30%, and 92.31% respectively.

Building an ATT&CK-Aligned Detection Program: Case Studies in Detection Engineering and Security Monitoring

Sri Sowmya Nemani, Independent Researcher, USA

ABSTRACT

Organizations continue to face increasingly sophisticated cyber threats that bypass traditional security controls. Security Operations Centres (SOCs) rely on detection engineering to identify malicious activity through logs, network telemetry, endpoint data, and authentication events. The MITRE ATT&CK framework provides a common language for understanding adversary behaviours and mapping security detections to real-world attack techniques. This paper explains how to build an ATT&CK-aligned detection program using practical case studies. The paper also discusses ATT&CK coverage, detection gaps, and applications across different industries. Results show that ATT&CK-aligned detections can improve threat visibility and security monitoring.

FBStegNet: Deep Learning-Based Robust Data Hiding in Color Images for Social Media

Hasan Abdulrahman, Northern Technical University, Iraq

ABSTRACT

Social-media steganography is a hostile channel problem rather than a conventional pixel editing problem. When a user uploads an im-age to Facebook, the platform may resize the image, recompress it as JPEG, alter chroma information, remove metadata, quantize colors, and apply proprietary optimization. These operations are not designed as attacks, yet they routinely erase payloads produced by fragile spatial and transform-domain steganographic schemes. This paper presents FB-StegNet, a deep neural framework for robust data hiding in color im-ages transmitted through Facebook like processing. The proposed sys-tem combines a dense binary message encoder, a residual CNN cover fea-ture extractor, a diflerentiable Facebook simulation layer, and a texture aware attention embedding network. The simulator is the main security oriented design element: it exposes the encoder and decoder during train-ing to randomized JPEG compression, downsampling upsampling, color quantization, and signal dependent noise. As a result, the learned embed-ding is optimized for recovery after a distribution of social-media trans-formations rather than for clean-image reconstruction alone. FBStegNet is formulated with a joint objective that balances bit recovery, visual dis-tortion, structural fidelity, and adaptive embedding energy. Additional, this work specifies a reproducible evaluation protocol using steganogra-phy image benchmarks, Facebook style simulated channels, real upload download tests, payload metrics, perceptual quality measures, and ste-ganalysis checks. FBStegNet therefore provides a practical and extensi-ble design for robust secret message communication through lossy social media image pipelines.

NavySync: Design and Implementation of a CrossPlatform Communication and Administration System for NJROTC Unit Management

Anders Lu and Austin Amakye Ansah, The University of Texas at Arlington, USA

ABSTRACT

NavySync is a cross-platform mobile and web system designed to centralize communication, event management, attendance tracking, learning resources, and role-based administration for Navy Junior Reserve Officers Training Corps (NJROTC) units [1]. Built with Flutter, Supabase, PostgreSQL, and a Svelte-based administrator portal, the system addresses recurring coordination problems in student organizations: scattered event information, delayed check ins, unclear leadership permissions, and limited parent visibility [2]. NavySync uses QR-code attendance, school-scoped data, targeted announcements, role-aware event creation, and parent-linked accounts to reduce administrative friction while keeping the experience usable for cadets, instructors, parents, and guest users. This paper presents the motivation, implementation challenges, system architecture, prototype evaluation approach, related work, and future improvements for the NavySync platform.

HYBRID HANDCRAFTED AND DEEP MULTI-ANGLE FEATURES FOR ROTATION-INVARIANT TEXTUREBASED IMAGE RETRIEVAL

Ayawo Désiré Dandji1and Nadia Baaziz1 1Department of Computer Science and Engineering, University of Quebec in Outaouais (UQO), Gatineau (Quebec), Canada

ABSTRACT

The rapid growth of visual databases calls for efficient Content-Based Image Retrieval (CBIR). Texture descriptors are central to these systems; however, their performance often degrades under geometric image transformations, particularly rotation. This paper presents a CBIR framework designed to compare handcrafted and deep texture features for rotation-invariant retrieval. A hybrid approach combines Local Binary Patterns (LBP) with the Stationary Wavelet Transform (SWT) to extract compact, multi-scale descriptors robust to orientation variability. In parallel, a transfer learning strategy leverages intermediate layers of pre-trained convolutional neural networks (VGG16 and ResNet50) with multi-angle feature aggregation to extract rotation-robust deep descriptors. Experiments on benchmark texture datasets (Outex and Kylberg) show that the deep transfer-learning approach achieves higher recall at the cost of larger descriptor dimensionality and greater computational and memory demands, whereas the proposed hybrid descriptor provides a favorable trade-off between accuracy, compactness, and computational efficiency, making it well-suited for resource-constrained applications.

ABSTRACT

Post-traumatic stress disorder remains difficult to monitor because care often depends on self-reported symptoms rather than continuous physiological observation. To address this problem, this paper presents VitalLink, a mobile and hardware-integrated system designed to support veterans and other users affected by PTSD through real-time monitoring, caregiver alerts, and AI-assisted guidance [1]. The system combines a Flutter mobile application, Firebase backend services, and a Raspberry Pi-based hardware layer equipped with sensors for heart rate and motion tracking. Local processing and language-model-based interpretation helps transform raw sensor readings into useful insights while preserving responsiveness [2]. Key implementation challenges included sensor reliability, secure account permissions, and balancing AI capability with hardware limits.

William Ding1, Rodrigo Onate2 1Fairmont Preparatory Academy, 2200 W Sequoia Ave, Anaheim, CA 92801 2California State University, Fullerton, 800 N State College Blvd, Fullerton, CA 92831

ABSTRACT

This paper presents MoodSync, a mobile application designed to help users improve emotional awareness and emotional well-being through journaling, mood surveys, and AI-generated music recommendations. Many individuals experience stress, anxiety, and emotional instability while lacking accessible mental health support tools. MoodSync addresses this issue by combining emotional reflection and personalized music therapy into a single mobile platform. The application was developed using Flutter for the frontend, Firebase Authentication and Cloud Firestore for secure user management and data storage, and the OpenAI API with YouTube integration for intelligent music recommendation generation and playback [1][2]. Several implementation challenges were considered, including emotional input reliability, survey consistency, and playlist personalization. Experiments were conducted to evaluate playlist mood accuracy and emotional improvement effectiveness. Results showed that the system performed well for positive emotional states but faced greater difficulty with more complex negative emotions such as anxiety and sadness. Overall, MoodSync demonstrates the potential of combining artificial intelligence, journaling, and music-based emotional support into an accessible and engaging emotional wellness application.

The Intelligent Incorporation of AI Tools to Enhance the Virtual Museum Experience Through ChatGPT, Unity, and Other Systems

Alex Li1, Moddwyn Andaya2 1Sage Hill School, 20402 Newport Coast Dr, Newport Coast, CA 92657

ABSTRACT

Traditional aviation museums are limited by geographical accessibility, high maintenance costs, and staffing shortages, reducing opportunities for public engagement and education. This paper presents an AI-powered virtual aviation museum that provides an immersive and interactive learning environment accessible through the internet. The platform uses three dimensional aircraft models and integrates ChatGPT as a virtual docent to answer user questions and enhance learning experiences [13]. Experimental evaluations were conducted to assess the quality of ChatGPT s responses and the effectiveness of a question-checking system. Results show that ChatGPT performs well for general informational queries but is less reliable when answering statistical questions, while the question-checking system accurately identifies appropriate user inquiries. The proposed system demonstrates how virtual reality and artificial intelligence can improve the accessibility and sustainability of aviation education and museum experiences.

Analysis of Lateral Offset Invariance in Parallel Parking Maneuver: A Geometric Simulation Study Kevin Luo and Hsinghan Meng

Sunny Hills High School, Fullerton, CA 92833, SAT Professionals, Diamond Bar, CA 91765

ABSTRACT

This paper investigates whether the initial lateral offset of a vehicle from the parking space, denoted ∆y, affects the vehicle s ability to successfully complete a parallel parking maneuver. Using the geometric mathematical model developed by Wahab et al. [1] and implemented via a simulation developed in a Java-based environment to allow for high-fidelity kinematic modelling and real-time geometric validation, a series of trials were conducted in which ∆y was systematically varied while all other vehicle and parking space parameters were held constant. The results demonstrate that, under the constraints of this model, the parallel parking maneuver can be completed successfully across a wide range of ∆y values. Specifically, varying ∆y causes the geometric solution to self-adjust: the intermediate quantities a, c, y1, and θ all recalculate such that a valid two-arc trajectory always exists. It is concluded that ∆y does not prevent a vehicle from parking, rather, it only shifts the starting position and arc geometry while preserving the feasibility of the maneuver .

Cue Clear: A Wearable Augmentative and Alternative Communication System to Display Caregiver-Curated Symbol Slideshows using a Flutter Mobile Application and a Wi-Fi-Connected CircuitPython Embedded Device

Yeuk Nam Nolan Liu1, Tyler Boulom2 1Lexington High school, 251 Waltham St, Lexington, MA 02421 2Woodbury University, 7500 N Glenoaks Blvd, Burbank, CA 91504

ABSTRACT

Many non verbal individuals depend on symbol based communication, yet AAC devices are frequently abandoned because they are bulky, conspicuous, or hard to reconfigure. Cue Clear addresses this with a wearable display that cycles through caregiver-curated communication symbols, controlled by a companion smartphone app. The system pairs a CircuitPython microcontroller driving an ILI9341 LCD hosting a non blocking HTTP server over a Wi Fi access point with a cross platform Flutter application that builds symbol “profiles” and activates them on the device [3]. Key challenges included reliable communication with a resource constrained device, responsive image browsing, and an accessible caregiver interface, these were met with a non-blocking embedded server, a read through image cache, and a large target, confirmation guarded UI. In testing, caching cut image load latency about 27 fold to 43 ms, and index only profile activation stayed near 215 ms regardless of profile size. By directly targeting known causes of AAC abandonment, Cue Clear offers a sustainable, low-friction communication aid. .
