*3.4. Classification*

This study aims to recognize nine environments, including bar, classroom, gym, kitchen, library, street, hall, living room and bedroom using the same methods and implementations, which are

implemented and tested in Reference [4]. The different implementations were performed with non-normalized and normalized data, implementing a stop criterion related to the maximum number of training interactions tested with three limits, namely: 106, 2 × 10<sup>6</sup> and 4 × 106.
