As a result, we had to go back to the drawing board and retrain a new model to get the performance we were looking for before deploying that model into our client’s workflows.A quick note on neural networks: while training generative AI models will be a bit different considering the ...

In the image, the model is depicted as a line drawn between the points. The model y = ax + b is the classical example of a linear model. You can see how a linear model could fit the example data in the following schematic drawing: In this picture, the data points are depicted on ...
