Parasite: A Steganography-based Backdoor Attack Framework for Diffusion Models
Authors: Jiahao Chen, Yu Pan, Yi Du, ChunKai Wu, Lin Wang
Date: 2025-04-08 00:00:00
Tasks: Backdoor Attack, Image Generation

Recently, the diffusion model has gained significant attention as one of the most successful image generation models, which can generate high-quality images by iteratively sampling noise. However, recent studies have shown that diffusion models are vulnerable to backdoor attacks, allowing attackers to enter input data containing triggers to activate the backdoor and generate their desired output. Existing backdoor attack methods primarily focused on target noise-to-image and text-to-image tasks, with limited work on backdoor attacks in image-to-image tasks. Furthermore, traditional backdoor attacks often rely on a single, conspicuous trigger to generate a fixed target image, lacking concealability and flexibility. To address these limitations, we propose a novel backdoor attack method called "Parasite" for image-to-image tasks in diffusion models, which not only is the first to leverage steganography for triggers hiding, but also allows attackers to embed the target content as a backdoor trigger to achieve a more flexible attack. "Parasite" as a novel attack method effectively bypasses existing detection frameworks to execute backdoor attacks. In our experiments, "Parasite" achieved a 0 percent backdoor detection rate against the mainstream defense frameworks. In addition, in the ablation study, we discuss the influence of different hiding coefficients on the attack results. You can find our code at https://anonymous.4open.science/r/Parasite-1715/.

A LoRA-Based Approach to Fine-Tuning LLMs for Educational Guidance in Resource-Constrained Settings
Authors: Md Millat, Md Motiur
Date: 2025-04-22 00:00:00
Tasks: Computational Efficiency, GPU, Quantization, Retrieval-augmented Generation, Specificity

The current study describes a cost-effective method for adapting large language models (LLMs) for academic advising with study-abroad contexts in mind and for application in low-resource methods for acculturation. With the Mistral-7B-Instruct model applied with a Low-Rank Adaptation (LoRA) method and a 4-bit quantization method, the model underwent training in two distinct stages related to this study's purpose to enhance domain specificity while maintaining computational efficiency. In Phase 1, the model was conditioned with a synthetic dataset via the Gemini Pro API, and in Phase 2, it was trained with manually curated datasets from the StudyAbroadGPT project to achieve enhanced, contextualized responses. Technical innovations entailed memory-efficient quantization, parameter-efficient adaptation, and continuous training analytics via Weights & Biases. After training, this study demonstrated a reduction in training loss by 52.7%, 92% accuracy in domain-specific recommendations, achieved 95% markdown-based formatting support, and a median run-rate of 100 samples per second on off-the-shelf GPU equipment. These findings support the effective application of instruction-tuned LLMs within educational advisers, especially in low-resource institutional scenarios. Limitations included decreased generalizability and the application of a synthetically generated dataset, but this framework is scalable for adding new multilingual-augmented and real-time academic advising processes. Future directions may include plans for the integration of retrieval-augmented generation, applying dynamic quantization routines, and connecting to real-time academic databases to increase adaptability and accuracy.

AN INTERNSHIP REPORT ON VIRTUAL MOUSE USING HAND GESTURES PROJECT
Authors: Kamal Acharya
Date: 2024-03-20 00:00:00
Proceeding: ResearchGate 2024 3

This paper proposes a virtual mouse system based on HCI using computer vision and hand gestures.Techniques for establishing the process of human-computer interaction(HCI) have evolved since the invention of computer technology. The mouse is its great invention in HCI (Human-Computer Interaction) technology. Wireless or Bluetooth mouse technology is still in development, but the technology is not yet completely device-free. The Bluetooth mouse requires battery power and a connection dongle. The presence of additional devices in the mouse makes it difficult to use. The proposed mouse system solves these limitations. We have written a program for controlling the mouse movement using Python and OpenCV with a real-time camera that detects hand patterns, tracks hand gesture patterns that replaces the work of a traditonal physical mouse. Gestures captured with a integrated camera or webcam are processed with recognition technology. The user can control some of the computer's cursor functions with hand gesturing movements. Primarily, users can left-click, right-click, and double-click by scrolling their hand up or down with various gestures. This system captures frames using a webcam or built-in camera, processes the frames to make them trackable, recognizes various gestures made by the user, and performs mouse functions. Therefore, the proposed mouse system eliminates dependence on device to use the mouse. So the development of HCI technology can help.

Internet telephony consists of a combination of hardware and software that enables you to use the Internet as the transmission medium for telephone calls. For users who have free, or fixed-price Internet access, Internet telephony software essentially provides free telephone calls anywhere in the world. In its simplest form, PC-to-PC Internet telephony can be as easy as hooking up a microphone to your computer and sending your voice through a cable modem to a person who has Internet telephony software that is compatible with yours. This basic form of Internet telephony is not without its problems, however. Connecting this way is slower than using a traditional telephone, and the quality of the voice transmissions is also not near the quality you would get when placing a regular phone call.

Proceeding: ResearchGate 2024 9

In order to understand today’s computers, it is important to study how computers evolved through time by discussing some of the major achievements. This section deals with the history of computers and identifies the major technological achievements of the four computer generations. Humans needed devices that could be used to perform calculations as early as the period when they kept animals and started to trade with other people. They realized the need to calculate and to record information. Many people agree that the history of calculation began with the Abacus around 5000 B.C. in Egypt and China. It has a wooden frame with balls or beads strung on parallel wires. It is used for calculations. Afterwards, other developments include the invention of the slide rule in the 1620’s and the first mechanical calculating machine in 1642. Probably the first computer was designed by Charles Babbage in 1822. He devised a machine called the difference engine. In 1834, Babbage proposed a more elaborate computing machine, called the analytical engine. It was completely mechanical and needed thousands of components. Babbage was unable to produce most of these parts due to the technological limitations of his time.

Graphics provides one of the most natural means of communicating with a computer, since our highly developed 2D and 3D pattern recognition allow us to perceive and process pictorial data rapidly and efficiently. Interactive computer graphics is the most important means of producing the pictures since the invention of photography and television. It has the added advantage that with the computer we can make pictures not only of concrete real world objects but also of abstract such as survey results. This project is a collision evasion process implemented in the form of a game. Here the user is allowed to control the movement of the plane through a collision course. The objective is to evade the obstacles and travel as far as possible. The plane's upward movement is controlled by the left mouse button. Holding and pressing the left mouse button takes the plane higher and releasing the button results in the plane descending down. As the distance covered increases the speed of the plane increases. The main obstacles are buildings and clouds. The user must make sure that no part of the plane touches either the clouds or the buildings. The plane is also equipped with a booster which the user can activate with the right mouse button. The booster makes the plane travel at a faster pace. The booster gets depleted when being used and replenishes gradually when not used. At any instance the user can pause the game by pressing "p" on the keyboard. Pressing the key again will resume the game. The library glut.h is utilized in the implementation of the game as it provides a wide range of options to draw the necessary shapes.

WebDev Enterprises is a medium sized company that develops Web applications using J2EE technology for its overseas clients such as BlueSoft Software Solutions and InterSolutions Private Limited. The management at WebDev recently conducted an analysis and discovered that it has not been able to use the code of its existing applications developed in J2EE when developing new J2EE applications. As a result, the deadlines for the new projects were not being met causing financial loss to WebDev Enterprises. Because of not being able to meet deadlines, WebDev Enterprises was losing its clients. In addition, the management of WebDev Enterprises found that it was a complex task to develop applications in J2EE. How can the management of WebDev solve the problem? Solution In order to be able to reuse the code of existing applications, WebDev must start creating Web based applications using C# and ASP.NET. C# provides features such as inheritance and interface that allow reusability of code. This means that code written for a specific application in C# can be easily used for another C# application. Inheritance feature of C# allows a class to inherit properties, which contain data and methods of another class. For example, if you create a class A and define certain properties such as name and address in it, and a display method to display the values contained in the properties, then you can use the properties and methods of A class in another class B. Interfaces in C# allow you to declare abstract methods. These interfaces can be implemented in multiple classes. Each class in which the interface is implemented can contain specific code for the abstract methods defined in the interface. Thus, with the use of C# features such as Inheritance and Interface, code of one C# application can be reused in another C# application. As a result, development time for creating an application in C# is reduced. With the use of C#, programmers working at WebDev Enterprises could develop applications efficiently and in less time. C# programming language is supported by Microsoft Visual Studio 2005, which is a rapid development tool for developing Windows based and Web based applications. The support for .NET Framework in C# allows you to create interactive user interfaces for applications in less time. The .NET Framework provides the Control class that helps use controls, their properties and methods to develop interactive user interfaces for an application in less time.

PRIME: Fast Primal-Dual Feedback Optimization for Markets with Application to Optimal Power Flow
Authors: Nicholas Julian Behr, Mattia Bianchi, Keith Moffat, Saverio Bolognani, Florian Dörfler
Date: 2025-04-22 00:00:00

Online Feedback Optimization (OFO) controllers iteratively drive a plant to an optimal operating point that satisfies input and output constraints, relying solely on the input-output sensitivity as model information. This paper introduces PRIME (PRoximal Iterative MarkEts), a novel OFO approach based on proximal-point iterations. Unlike existing OFO solutions, PRIME admits a market-based implementation, where self-interested actors are incentivized to make choices that result in a safe and efficient operation, without communicating private costs or constraints. Furthermore, PRIME can cope with non-smooth objective functions, achieve fast convergence rates and rapid constraint satisfaction, and reject measurement noise. We demonstrate PRIME on an AC optimal power flow problem, obtaining an efficient real-time nonlinear local marginal pricing scheme.
