Real-Time Decision Fusion for Multimodal Neural Prosthetic Devices

Figure 4

Fusion results of using potentially poor quality decoders.

These two sets correspond to trials 2 and 3 in Table 3. (A) Example trials showing individual and fusion decodes. True velocities are shown in red. The fused ANN and fused Kalman filter decodes are shown in brown and black, respectively. Individual decoders are plotted in varying shades of grey. (B) Corresponding pointwise root mean squared error of decodes over time. Note that time is unitless in these simulations. Though the decoders have variable accuracy over time, the fusion algorithms maintain acceptable decoding accuracy throughout the entire trials.
