2 Figure 1 Basic working principle of neural network. The input parameters in the input layer are represented by neurons. The values are forwarded to the neurons in the hidden layer for evaluation with weight and bias. The final decision was transmitted to the output layer. Note: there could be multiple inputs, hidden layer, and outputs in a typical neural network.

8 Figure 7 Predicted tablet breaking force of 10 randomly selected tablets from internal data samples. The blue line depicts the experimental results and red line with square markers depicts predicted results. Each data point represents the mean value of 10 experimental data samples. The error bars are the ±1 standard deviation. Journal of Pharmaceutical Sciences  , DOI: ( /j.xphs ) Copyright © 2016 American Pharmacists Association® Terms and Conditions
