    Authors: Kokk, Getriin;

    Middle school curriculum by the government of Estonia supports digital competence, techno-logical and innovative development but does not set exact guidelines for teaching. At the moment, middle school informatics focus mainly on teaching of how to use a computer rather than teaching informatics and programming. Due to curriculum not having exact guidelines for the subject, the objective for this thesis was to create lesson plans and educational materials on education of computational thinking with unplugged programming for the II and III stage of middle school. All materials created for this thesis were tested and assessed by the students on the following topics: captivation; likeability; understandability of the material.

    Authors: Kurylenko, Oleksandr;

    In this work, two deep learning models based on convolutional neural networks (CNNs) are developed for one-day-ahead hourly electricity consumption forecasting for the next calendar day. One-day-ahead electricity consumption forecasting is done to perform baseline load evaluation for the assessment of Demand Response (DR) performance and to predict the availability of flexibility products. Using electricity consumption time series data for three regions in Norway, the developed CNNbased models are compared to four industry-standard baseline models (Asymmetric High Five of Ten, Similar Profile Five of Ten, Average, and Daily Profile). Additionally, comparisons are made to a Naive model and an Autoregressive Integrated Moving Average (ARIMA) model, which includes Fourier terms. Three evaluation metrics are used to estimate the models’ performance. A detailed description of the methodology, work pipeline, and results is provided. The conducted experiments were successful in developing and applying the CNN-based models to the problem of one-day-ahead hourly electricity consumption forecasting for the next calendar day. The developed CNN and combination “CNN + Long Short-Term Memory (LSTM)” models showed the best performance results among the predictive models which employ the Multiple-Input Multiple-Output (MIMO) strategy to forecast 24 hours ahead. The Daily Profile model showed the best performance among models which cannot forecast 24 hours ahead or do not necessarily employ the MIMO strategy. It is worth noting that the Average model showed the best performance in the baseline load evaluation among all the considered models. However, the Average model is only a reference comparison which does not actually perform forecasting, but rather uses post-event data. It can be concluded that the work was successful in developing and applying the CNN-based models to short-term load forecasting in energy systems, especially since the developed CNN and CNN+LSTM models outperformed other similar forecasting models. Two different paths could be chosen for future work: one that intends to explore more and improve the CNN-based models developed in this work, and the one which aims to explore new CNN-based architectures.

    Authors: Reitsakas, Jelizaveta;

    Programmeerimise õpetamisel tuleb pöörata tähelepanu õppijate teadmiste ja oskuste taseme hindamisele nii õppe alguses kui ka selle lõppemisel. Seda saab teha testi vormis. Magistritöö eesmärgiks on luua valideeritud test, mille abil saab hinnata õppijate teadmisi ja oskusi programmeerimiskursuse “Tehnoloogia tarbijast loojaks” alguses ja/või lõpus. Töö esimeses peatükis on toodud ülevaade Venemaal ja USAs kasutusel olevatest valideeritud testidest. Töö teises peatükis on kirjeldatud testi loomise protseduuri ning piloteerimise protsessi. Töö tulemusena loodud test piloteeriti kursuse “Tehnoloogia tarbijast loojaks” arvestustööks ettevalmistava testina. Võib öelda, et testi on võimalik kasutada nimetatud kursuse õppijate teadmiste ja oskuste hindamisel.

    Authors: Puskar, Linnet;

    The purpose of this master’s thesis is to provide an overview of the XGBoost algorithm and examine its suitability to model the claim frequency of motor third party liability insurance. The first three chapters introduce generalized linear models, generalized additive models and the algorithms of gradient boosting and XGBoost. In the fourth chapter, the aforementioned methods are applied on the data of Estonian Motor Insurance Bureau to predict claim frequency.

    Robotite ning inimeste ruumi jagamiseks ning koostöö jaoks on vajalik omavaheline suhtlus. Roboti ja inimese vahelises suhtluses on tähtis nii masinapoolne inimese mõistmine kui ka see, et inimene mõistaks roboti poolt edastatut. Selleks on vaja, et robot suudaks end inimesele arusaadaval viisil selgeks teha. Käesoleva magistritöö eesmärgiks oli uurida erinevaid võimalusi roboti kavatsuse väljendamiseks ning selle raames koostati kirjanduse kokkuvõte erinevatest juba välja pakutud kavatsuse väljendamise variantidest, viidi läbi küsitlus Eesti inimeste seas, et analüüsida nende arusaamist masina kavatsusest ning loodi masina mudel, mida visualiseeriti simulatsioonikeskkonnas. Küsimustikust selgus, et Eesti inimesed ei pruugi masina poolt edastatavaid emotsioone mõista, kui kasutatakse ainult roboti silmi. Samuti selgus, et ilma eelnevate teadmisteta ei olnud inimesed võimelised sõidukite kavatsusi ära tundma, kui kasutuses olid LED-ribad või -ekraanid, projektsioonide puhul said inimesed sõiduki kavatsusest aru. In english: For humans and robots to share space and cooperate, it is necessary to communicate with each other. In the communication between a human and a robot it is important for the machine to understand the human and also for the human to understand the information transmitted by the robot. This requires, that the robot would be able to make itself clear to humans in an understandable way. The aim of this thesis was to evaluate different approaches to communicate the intent of a machine. During the master’s thesis, an overview of various options already proposed to express intent was given, a suvery was conducted among Estonian people to analyze their understanding of machine intent and a model of an autonomous car capable of communicating intent was proposed and visualised in a simulator. The survey revealed that Estonians may not understand the emotions of a machine if only robot’s eyes are used. It was also found that without prior knowledge, people were not able to understand vehicle intent when LED strips and displays were used, people recognized the intent when projections were used.

    Authors: Haske, Joseph Lyle;

    The purpose of this thesis is to explore stochastic volatility models to price American and European options. The two methods used are both based on a quadrinomial tree, but the first uses an Ornstein-Uhlenbeck process and the Monte Carlo method with a quadrinomial recombining tree and the second uses the Heston model and a tree-based approach that combines a grid and bilinear interpolation to estimate the option price. The thesis is split into four chapters. In the first chapter, it gives an overview of options, option pricing models, and numerical methods. The second chapter discusses the quadrinomial recombining tree, and the third presents the tree-based approach that uses a grid and bilinear interpolation. Finally the fourth, presents the results of both methods and then compares their performance and flexibility.

    Authors: Kokk, Getriin;

    Middle school curriculum by the government of Estonia supports digital competence, techno-logical and innovative development but does not set exact guidelines for teaching. At the moment, middle school informatics focus mainly on teaching of how to use a computer rather than teaching informatics and programming. Due to curriculum not having exact guidelines for the subject, the objective for this thesis was to create lesson plans and educational materials on education of computational thinking with unplugged programming for the II and III stage of middle school. All materials created for this thesis were tested and assessed by the students on the following topics: captivation; likeability; understandability of the material.

    Authors: Kurylenko, Oleksandr;

    In this work, two deep learning models based on convolutional neural networks (CNNs) are developed for one-day-ahead hourly electricity consumption forecasting for the next calendar day. One-day-ahead electricity consumption forecasting is done to perform baseline load evaluation for the assessment of Demand Response (DR) performance and to predict the availability of flexibility products. Using electricity consumption time series data for three regions in Norway, the developed CNNbased models are compared to four industry-standard baseline models (Asymmetric High Five of Ten, Similar Profile Five of Ten, Average, and Daily Profile). Additionally, comparisons are made to a Naive model and an Autoregressive Integrated Moving Average (ARIMA) model, which includes Fourier terms. Three evaluation metrics are used to estimate the models’ performance. A detailed description of the methodology, work pipeline, and results is provided. The conducted experiments were successful in developing and applying the CNN-based models to the problem of one-day-ahead hourly electricity consumption forecasting for the next calendar day. The developed CNN and combination “CNN + Long Short-Term Memory (LSTM)” models showed the best performance results among the predictive models which employ the Multiple-Input Multiple-Output (MIMO) strategy to forecast 24 hours ahead. The Daily Profile model showed the best performance among models which cannot forecast 24 hours ahead or do not necessarily employ the MIMO strategy. It is worth noting that the Average model showed the best performance in the baseline load evaluation among all the considered models. However, the Average model is only a reference comparison which does not actually perform forecasting, but rather uses post-event data. It can be concluded that the work was successful in developing and applying the CNN-based models to short-term load forecasting in energy systems, especially since the developed CNN and CNN+LSTM models outperformed other similar forecasting models. Two different paths could be chosen for future work: one that intends to explore more and improve the CNN-based models developed in this work, and the one which aims to explore new CNN-based architectures.

    Programmeerimise õpetamisel tuleb pöörata tähelepanu õppijate teadmiste ja oskuste taseme hindamisele nii õppe alguses kui ka selle lõppemisel. Seda saab teha testi vormis. Magistritöö eesmärgiks on luua valideeritud test, mille abil saab hinnata õppijate teadmisi ja oskusi programmeerimiskursuse “Tehnoloogia tarbijast loojaks” alguses ja/või lõpus. Töö esimeses peatükis on toodud ülevaade Venemaal ja USAs kasutusel olevatest valideeritud testidest. Töö teises peatükis on kirjeldatud testi loomise protseduuri ning piloteerimise protsessi. Töö tulemusena loodud test piloteeriti kursuse “Tehnoloogia tarbijast loojaks” arvestustööks ettevalmistava testina. Võib öelda, et testi on võimalik kasutada nimetatud kursuse õppijate teadmiste ja oskuste hindamisel.

    Robotite ning inimeste ruumi jagamiseks ning koostöö jaoks on vajalik omavaheline suhtlus. Roboti ja inimese vahelises suhtluses on tähtis nii masinapoolne inimese mõistmine kui ka see, et inimene mõistaks roboti poolt edastatut. Selleks on vaja, et robot suudaks end inimesele arusaadaval viisil selgeks teha. Käesoleva magistritöö eesmärgiks oli uurida erinevaid võimalusi roboti kavatsuse väljendamiseks ning selle raames koostati kirjanduse kokkuvõte erinevatest juba välja pakutud kavatsuse väljendamise variantidest, viidi läbi küsitlus Eesti inimeste seas, et analüüsida nende arusaamist masina kavatsusest ning loodi masina mudel, mida visualiseeriti simulatsioonikeskkonnas. Küsimustikust selgus, et Eesti inimesed ei pruugi masina poolt edastatavaid emotsioone mõista, kui kasutatakse ainult roboti silmi. Samuti selgus, et ilma eelnevate teadmisteta ei olnud inimesed võimelised sõidukite kavatsusi ära tundma, kui kasutuses olid LED-ribad või -ekraanid, projektsioonide puhul said inimesed sõiduki kavatsusest aru. In english: For humans and robots to share space and cooperate, it is necessary to communicate with each other. In the communication between a human and a robot it is important for the machine to understand the human and also for the human to understand the information transmitted by the robot. This requires, that the robot would be able to make itself clear to humans in an understandable way. The aim of this thesis was to evaluate different approaches to communicate the intent of a machine. During the master’s thesis, an overview of various options already proposed to express intent was given, a suvery was conducted among Estonian people to analyze their understanding of machine intent and a model of an autonomous car capable of communicating intent was proposed and visualised in a simulator. The survey revealed that Estonians may not understand the emotions of a machine if only robot’s eyes are used. It was also found that without prior knowledge, people were not able to understand vehicle intent when LED strips and displays were used, people recognized the intent when projections were used.

    Authors: Haske, Joseph Lyle;

    The purpose of this thesis is to explore stochastic volatility models to price American and European options. The two methods used are both based on a quadrinomial tree, but the first uses an Ornstein-Uhlenbeck process and the Monte Carlo method with a quadrinomial recombining tree and the second uses the Heston model and a tree-based approach that combines a grid and bilinear interpolation to estimate the option price. The thesis is split into four chapters. In the first chapter, it gives an overview of options, option pricing models, and numerical methods. The second chapter discusses the quadrinomial recombining tree, and the third presents the tree-based approach that uses a grid and bilinear interpolation. Finally the fourth, presents the results of both methods and then compares their performance and flexibility.
