Machine Learning Optimization of KPI Prediction
Haris, Daniel ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
This thesis aims to optimize the machine learning algorithms for predicting KPI metrics for an organization. The organization is predicting whether projects meet planned deadlines of the last phase of development process using machine learning. The work focuses on the analysis of prediction models and sets the goal of selecting new candidate models for the prediction system. We have implemented a system that automatically selects the best feature variables for learning. Trained models were evaluated by several performance metrics and the best candidates were chosen for the prediction. Candidate models achieved higher accuracy, which means, that the prediction system provides more reliable responses. We suggested other improvements that could increase the accuracy of the forecast.

Reporting of the Selected Firm
Němec, Vlastimil ; Novotná, Eva (referee) ; Hanušová, Helena (advisor)
This work deals with reporting as a tool for the creation of a comprehensive system of data and indicators testifying about the company's activities in an understandable and user-compact format. Further demonstrated by the practical use of examples and forms of reports to highlight the crucial and often repetitive deficiencies and errors in the use of business information. Based on detailed analyzes are evaluated selected reports and recommendations are defined to make the process of reporting more effective. Selected reports are supplemented by a range of new information that will enhance the management process and therefore lead to savings. These savings are discussed in detail in one of the recommendations of the work on the introduction of CRM IS.
