Figure 5: Performance of ANN models to predict the initial rate of production of H2 (top) and final hydrogen concentration (bottom) for 625 data points from the validation dataset. The models were built on input/output vectors from 32 simulations (BaseA) and 12 simulations (BaseB). Straight line on each graph represents bisector. Values on x and y axis are normalized values for both rate of H2 production and final H2 concentration.
