Abstract
This disclosure provide a bottom sediment determining device, which is inputted with an echo signal corresponding to an ultrasonic wave outputted underwater, and determines water bottom sediment using a neural network. The device includes a memory for storing two or more parameters to be used in the neural network so as to be associated with positional information, a receiver for receiving the positional information, an acquisition module for acquiring the parameters corresponding to the positional information, and a setting module for setting the parameters to the neural network.

A bottom sediment determining device for being inputted with an echo signal corresponding to an ultrasonic wave outputted underwater, and determining water bottom sediment using a neural network, the device comprising:
- a memory for storing a set of two or more synaptic connection coefficients to be used in the neural network so as to be associated with positional information;
- a receiver for receiving the positional information, the positional information representing a location where the water bottom sediment is determined;
- an acquisition module for acquiring the set of synaptic connection coefficients corresponding to the positional information, said acquiring being accomplished by selecting the set of synaptic connection coefficients from among a plurality of sets of synaptic connection coefficients based on the received positional information, the selected set of synaptic connection coefficients being different from a previously-selected set of synaptic connection coefficients even if a water depth and bottom sediment determination are the same as those associated with the previously-selected set of synaptic connection coefficients;
- and
- a setting module for setting the acquired set of synaptic connection coefficients to the neural network.
