1. 16. Understanding Sales Performance Using Natural Language Processing - An experimental study evaluating rule-based algorithms in a B2B setting

   Master-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

   Författare :Angelica Smedberg; [2023]
   Nyckelord :NLP; Sentiment Analysis; Ruled-based algorithms; TextBlob; VADER; Naïve Bayes; Machine Learning;

   Sammanfattning : Natural Language Processing (NLP) is a branch in data science that marries artificial intelligence with linguistics. Essentially, it tries to program computers to understand human language, both spoken and written. Over the past decade, researchers have applied novel algorithms to gain a better understanding of human sentiment. LÄS MER

3. 17. Dataset characteristics effect on time series forecasting : comparison of statistical and deep learning models

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

   Författare :Adam Ahlman; Adam Taylor; [2023]
   Nyckelord :Time Series; Forecasting;

   Sammanfattning : Time series are points of data measured throughout time in equally spaced periods. They present characteristics such as level, noise, trend, seasonality, and outliers. Time series forecasting is the attempt to predict single or multiple future values. LÄS MER

4. 18. Condition Monitoring Of Machine Components From Drive Data Using Semi-Supervised Anomaly Detection Methods

   Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

   Författare :Tim Leon WyWiol; [2023]
   Nyckelord :;

   Sammanfattning : The mission of the machine manufacturer is to gain insights from machine data to increase their machines' efficiency and sustainability. Continuously monitoring the machine data with machine learning helps to detect emerging mechanical problems and prevents unexpected failures. LÄS MER

5. 19. Are expert judgments a reliable tool for predicting farmer and food consumer decisions? : experimental evidence from a forecasting survey

   Master-uppsats, SLU/Dept. of Economics

   Författare :Adam Warren Kirby; [2023]
   Nyckelord :Experimental economics; forecasting; food-chain actors; food choice; agricultural policy;

   Sammanfattning : Often trusted to provide sound recommendations and advice, experts from academia and industry are often relied upon throughout industries around the globe, and the food and agriculture industry is no different. We therefore ask, how accurate are these experts, and are they able to accurately forecast behavior from varying food chain actors such as farmers and consumers? Do these experts have a preconceived bias to one side or the other? These questions become increasingly important when considering policy developments such as the EU Farm to Fork strategy, which seek to integrate the consumer-facing food industry and the producer-forward agriculture industry, two policy realms that have historically remained relatively independent of one another.

7. 20. Credit Index Forecasting: Stability of an Autoregressive Model

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Melker Wallén; Erik Grimlund; [2023]
   Nyckelord :Credit spreads; Time Series; Credit Risk; Index Modeling; Forecasting; Kreditspreadar; Tidsserier; Kreditrisk; Indexmodellering; Prognoser;

   Sammanfattning : This thesis investigates the robustness and stability of total return series for credit bond index investments. Dueto the challenges which arise for financial institutes and investors in achieving these objectives, we aim to createa forecasting model which matches the statistical properties of historical data, while remaining robust, stable andeasy to calibrate.
