Data Mining in Small Business
 Sabovčik, František ; Burgetová, Ivana (oponent) ; Zendulka, Jaroslav (vedoucí práce)
This thesis has as an objective to evaluate techniques of data mining for use in small business. By examining data and consultations with domain experts, two approaches were chosen: market basket analysis and sales forecasting. For market basket analysis, Relim algorithm together with metrics measuring interestingness of association rules. For prediction task, decompostion model, SARIMA, MARS and time-lagged neural network models were implemented. Acceptable results were obtained by hyper-parameter optimization. In contrast to expectation, additional weather data and use of non-linear model did not improve accurancy above SARIMA model. Forecasting was implemented as a backend service for testing in production.
