    22 The following sub-sections briefly describe the individual representation formats. 
    23  
    24 === 3.2.1. Feature vectors === 
    25 Feature vectors can be represented in an ad hoc format. In text form (see Figure 3), the feature vectors consist of straightforward key-value pairs – one feature per line, values preceding features. 
    26  
    27 As feature vectors may be sent very frequently (e.g., every 10 ms in the SEMAINE system 1.0), compact representation is a relevant issue. For this reason, a binary representation of feature vectors is also available. In binary form, the feature names are omitted, and only feature values are being communicated. The first four bytes represent an integer containing the number of features in the vector; the remaining bytes contain the float values one after the other.
