Generating vectors from data

The invention discloses an apparatus for converting data and for assessing data. The apparatus comprises a processor. For converting data, the processor is configured to train a neural network arrangement to generate a first vector to represent input data, each element of the first vector representing a defined feature of the input data. For assessing data, the processor is configured to provide a neural network trained to generate a first vector representing input data; provide input data to the trained neural network; and generate, using the trained neural network, a first vector representing the input data, wherein each element of the generated first vector represents a defined feature of the input data. Methods and a computer program product are also disclosed.
