2007 – 2008 Final Year Project – 1st Term Report
In this semester, we studied different representation of the data, different classification
methods as well as different methods to increase the classification rate. At this stage, we
have the following configuration:
- Weapon to study: Dao (Sabre)
- Representation of Data: Raw Format
- Data Preprocessing: None
- Classification Algorithm: Dynamic Time Warping on 3D Space
This chapter comprises the following sections:
� 4.1 Terminology
� 4.2 The Design Structure
� 4.3 Classification Working Flow
� 4.4 Chosen Weapon – Dao
� 4.5 Chosen Data Representation – Raw Format
� 4.6 Chosen Data Preprocessing – None
� 4.7 Chosen Algorithm – Dynamic Time Warping
� 4.7.1 Why Dynamic Time Warping?
� 4.7.2 Initial Coding – Used Dynamic Time Warping wrongly
