The displayed graph is from a forecasting model for testing a time series.


Considering the graph only, which conclusion should a Machine Learning Specialist make about the behavior of the model?

This graph shows the training and validation loss against the epochs for a neural network.

The network being trained is as follows:
• Two dense layers, one output neuron
• 100 neurons in each layer
• 100 epochs
• Random initialization of weights


Which technique can be used to improve model performance in terms of accuracy in the validation set?
