Vsebina:
Content (Syllabus outline):

Osnovne lastnosti senzorskih podatkov in metapodatkov za potrebe analize senzorskih podatkov, vključno s statističnimi podatki, podatki o lokaciji senzorjev in dinamičnimi podatki povezanimi s časom.

Primerjava obravnavanja senzorskih podatkov iz podatkovne baze in senzorskih podatkov, pridobljenih v realnem času.

Predprocesiranje senzorskih podatkov, vključno s čiščenjem podatkov in bogatenjem podatkov z uporabo predznanja in/ali konteksta.

Integracija drugih relevantnih podatkov (npr. vreme, tekstovna sporočila) s senzorskimi podatki.

Osnovne in napredne metode za analizo senzorskih podatkov in velikih količin podatkov, vključno s prepoznavanjem vzorcev, detekcijo anomalij, modeliranjem in napovedovanjem.

Poglobljeno individualno delo na obravnavi realnega primera iz študentovega raziskovalnega dela: izbira primernih podatkov in relevantnega problema, ki ga bo študent obravnaval z metodami analize senzorskih podatkov, izbira primernih pristopov za predprocesiranje podatkov in metod za analizo podatkov.

Basic properties of sensor data and sensor metadata from the viewpoint of sensor data analysis including static data, data connected to sensor location and dynamic data connected to time.

Comparison of handling sensor data stored in a database and handling sensor data obtained from a real-time data stream.

Pre-processing of sensor data including: data cleaning, sensor data enrichment using background knowledge and/or context.

Integration of other relevant data (e.g. weather, text messages) with sensor data.

Basic and advanced methods for sensor data and big data analysis including pattern matching and recognition, anomaly detection, modelling and prediction.

In-depth individual study of a real case related to student’s research interests: selection of data sources and a relevant problem to be addressed via sensor data analysis, selection of appropriate data pre-processing and suitable data analysis methods.
