Artificiell Intelligens och digitalisering i revisionsbranschen : Utmaningar och möjligheter på revisionsprocess och revisionskvalitet

Paulsen, Jennifer, Jansson, Maja January 2024 (has links)
Under de senaste åren har revisionsbranschen genomgått betydande förändringar med införandet av digitalisering och olika digitala verktyg. Under det senaste året har Artificiell Intelligens (AI) blivit alltmer framträdande och förväntas fortsätta att utvecklas. Revisionsbyråer integrerar digitala verktyg för att optimera revisionsprocessen, förbättra kvaliteten på revisionerna och reducera risken för konkurrens. Användning av AI-teknik kan signalera att revisionsbyrån ligger i framkant med tekniska verktyg och därmed öka revisionens trovärdighet. Tidigare forskning betonar fördelarna med att implementera digitala verktyg, som AI-teknik, i revisionsarbetet. Det förväntas att detta ska medföra effektivisering, flexibilitet, resursbesparing samt möjlighet att fokusera på andra mer komplexa arbetsuppgifter för revisorn. Syftet med den föreliggande studien är att undersöka hur användningen av AI-teknik och digitalisering påverkar revisionsprocess, revisionskvalitet och revisorns kompetenskrav. Studien utforskar dessutom revisorers uppfattning och acceptans av teknologiska innovationer hos revisionsbyråer som ingår i The Big Four. För att åstadkomma detta genomfördes intervjuer med elva revisorer av olika yrkesbefattning. Resultaten från den föreliggande studien indikerar att majoriteten av respondenterna har en positiv inställning till AI-tekniken och dess framtida utveckling. Dessutom framhåller respondenterna att tekniken är ett värdefullt hjälpmedel och stöd under revisionsprocessen genom att erbjuda vägledning och insikter.  Studien framhäver vikten av att använda AI-teknik inom revision med försiktighet och betonar att revisorns mänskliga kompetens och expertis fortfarande är avgörande för både revisionskvalitet och klientförtroende. Trots att majoriteten av respondenterna ser potential i hur AI-teknik kan förbättra deras arbete, påpekar studien att tekniken fortfarande är i ett tidigt utvecklingsstadium. Studien har resulterat i att AI-teknik inte är så etablerad som tidigare forskning har indikerat. Det har också observerats att revisorer behöver ökad kunskap om AI för att effektivt kunna använda tekniken i sin revision, vilket kan åstadkommas genom utbildning. Dessa slutsatser indikerar att AI-tekniken fortsätter att genomgå betydande förbättringar och att dess fulla potential ännu inte har realiserats. / Artificial Intelligence and Digitalization in the Auditing Industry: Challenges and Opportunities for the Auditing Process and Audit Quality In recent years, the auditing industry has undergone significant changes with the introduction of digitalization and various digital tools. Over the past year, Artificial Intelligence (AI) has become increasingly prominent and is expected to continue developing. Audit firms are integrating digital tools to optimize the auditing process, improve audit quality, and reduce the risk of competition. The use of AI-technology can signal that the audit firm is at the forefront of technological tools, thereby increasing the credibility of the audit. Previous research emphasizes the benefits of implementing digital tools, such as AI-technology, in auditing work. It is expected that this will lead to increased efficiency, flexibility, resource savings, and the ability for auditors to focus on other, more complex tasks.The purpose of the present study is to examine how the use of AI-technology and digitalization affects the auditing process, audit quality, and the competence requirements for auditors. The study also explores auditors' perceptions and acceptance of technological innovations at audit firms within The Big Four. To achieve this, interviews were conducted with eleven auditors of various professional positions. The results from the present study indicate that the majority of respondents have a positive attitude towards AI-technology and its future development. Additionally, the respondents highlight that the technology is a valuable tool and support during the auditing process by providing guidance and insights.The study highlights the importance of using AI-technology in auditing with caution and emphasizes that the auditor's human competence and expertise remain crucial for both audit quality and client trust. Although the majority of respondents see potential in how AI-technology can enhance their work, the study points out that the technology is still in an early stage of development. The study has shown that AI-technology is not as established as previous research has indicated. It has also been observed that auditors need increased knowledge about AI to effectively use the technology in their audits, which can be achieved through education. These conclusions indicate that AI-technology continues to undergo significant improvements and that its full potential has yet to be realized.

Grön AI : En analys av maskininlärningsalgoritmers prestanda och energiförbrukning

Berglin, Caroline, Ellström, Julia January 2024 (has links)
Trots de framsteg som gjorts inom artificiell intelligens (AI) och maskininlärning (ML), uppkommer utmaningar gällande deras miljöpåverkan. Fokuset på att skapa avancerade och träffsäkra modeller innebär ofta att omfattande beräkningsresurser krävs, vilket leder till en hög energiförbrukning. Syftet med detta arbete är att undersöka ämnet grön AI och sambandet mellan prestanda och energiförbrukning hos två ML-algoritmer. De algoritmer som undersöks är beslutsträd och stödvektormaskin (SVM), med hjälp av två dataset: Bank Marketing och MNIST. Prestandan mäts med utvärderingsmåtten noggrannhet, precision, recall och F1-poäng, medan energiförbrukningen mäts med verktyget Intel VTune Profiler. Arbetets resultat visar att en högre prestanda resulterade i en högre energiförbrukning, där SVM presterade bäst men också förbrukade mest energi i samtliga tester. Vidare visar resultatet att optimering av modellerna resulterade både i en förbättrad prestanda men också i en ökad energiförbrukning. Samma resultat kunde ses när ett större dataset användes. Arbetet anses inte bidra med resultat eller riktlinjer som går att generalisera till andra arbeten. Däremot bidrar arbetet med en förståelse och medvetenhet kring miljöaspekterna gällande AI, vilket kan användas som en grund för att undersöka ämnet vidare. Genom en ökad medvetenhet kan ett gemensamt ansvar tas för att utveckla AI-lösningar som inte bara är kraftfulla och effektiva, utan också hållbara. / Despite the advancements made in artificial intelligence (AI) and machine learning (ML), challenges regarding their environmental impact arise. The focus on creating advanced and accurate models often requires extensive computational resources, leading to a high energy consumption. The purpose of this work is to explore the topic of green AI and the relationship between performance and energy consumption of two ML algorithms. The algorithms being evaluated are decision trees and support vector machines (SVM), using two datasets: Bank Marketing and MNIST. Performance is measured using the evaluation metrics accuracy, precision, recall, and F1-score, while energy consumption is measured using the Intel VTune Profiler tool. The results show that higher performance resulted in higher energy consumption, with SVM performing the best but also consuming the most energy in all tests. Furthermore, the results show that optimizing the models resulted in both improved performance and increased energy consumption. The same results were observed when a larger dataset was used. This work is not considered to provide results or guidelines that can be generalized to other studies. However, it contributes to an understanding and awareness of the environmental aspects of AI, which can serve as a foundation for further exploration of the topic. Through increased awareness, shared responsibility can be taken to develop AI solutions that are not only powerful and efficient but also sustainable.

Sabe-se que o aprendizado ? algo extremamente particular, pois cada estudante possui estilos pr?prios e pode sofrer mudan?as diante de situa??es diversas como, por exemplo, objetivo, motiva??o, personalidade, etc. Por isso, o conceito de adaptabilidade do conte?do did?tico tem se tornado de grande import?ncia na personaliza??o do Sistema de Gerenciamento de Aprendizagem (SGA). Diante desse fato, Dor?a (2012) prop?e uma abordagem de Sistema Adaptativo e Inteligente para Educa??o (SAIE), utilizando t?cnicas probabil?sticas e Intelig?ncia Artificial (IA), capaz de detectar e adaptar, de maneira din?mica e autom?tica, os estilos de aprendizagem do estudante, considerando o Modelo de Estilo de Aprendizagem Felder-Silverman?s. Ap?s pesquisa detalhada, foram propostas algumas adapta??es baseadas na abordagem original, alterando o funcionamento de dois componentes espec?ficos: o M?dulo Pedag?gico e o Componente de Modelagem do Estudante. Al?m disso, prop?e-se uma nova estrutura do Modelo Estudante, contemplando o hist?rico de desempenho do aluno nos processos avaliativos. Por conseguinte, realizaram-se testes para avaliar os impactos de tais mudan?as por meio uma compara??o estat?stica utilizando o m?todo T-Pareado. Pelos resultados obtidos, as ideias deste trabalho proporcionaram uma melhora m?dia de 6,07% no desempenho avaliativo do estudante e uma redu??o m?dia de 68,27% nos problemas de aprendizagem, demonstrando efici?ncia e efic?cia da proposta. / Disserta??o (Mestrado Profissional) ? Programa de P?s-Gradua??o em Educa??o, Universidade Federal dos Vales do Jequitinhonha e Mucuri, 2015. / Since last decade many researchers have been conducting studies on personalized and intelligent assistance in distance education based on identification of learning styles. It is known that learning is something very particular because each student has their own styles and are subject to change on a variety of situations such as goal, motivation, personality, etc. Therefore, this study discusses the concept of adaptability of educational content as a way to provide customization of Learning Management System (LMS). Through probabilistic techniques and Artificial Intelligence (AI), Dor?a (2012) proposed a approach Adaptive and Intelligent System for Education (AIES) able to dynamically and automatically detect, select and adapt learning objects based on the student?s profile through Felder-Silverman Learning Styles Model (FSLSM). After detailed study, it has been proposed some adaptations based on this approach, thereby altering the operation of two specific components: the Pedagogical Module and the Student Modeling Component. In addition, it is proposed a new structure Model Student, considering learner performance history in the evaluation processes. Therefore, it carried out tests to assess the impacts of such changes through a statistical comparison by T-Paired method. From the results, the ideas in this work provides an average improvement of 6.07% in the performance evaluation of the student and an average reduction of 68.27% in the learning problems, demonstrating proposal of efficiency and effectiveness.

Instructing workers through a head-worn Augmented Reality display and through a stationary screen on manual industrial assembly tasks : A comparison study

Kenklies, Kai Malte January 2020 (has links)
It was analyzed if instructions on a head-worn Augmented Reality display (AR-HWD) are better for manual industrial assembly tasks than instructions on a stationary screen. A prototype was built which consisted of virtual instruction screens for two example assembly tasks. In a comparison study participants performed the tasks with instructions through an AR-HWD and alternatively through a stationary screen. Questionnaires, interviews and observation notes were used to evaluate the task performances and the user experience. The study revealed that the users were excited and enjoyed trying the technology. The perceived usefulness at the current state was diverse, but the users saw a huge potential in AR-HWDs for the future. The task accuracy with instructions on the AR-HWD was equally good as with instructions on the screen. AR-HWDs are found to be a better approach than a stationary screen, but technological limitations need to be overcome and workers need to train using the new technology to make its application efficient.
