To build a self-growing neural network, we can use a technique called neural architecture search (NAS) which automatically searches for the optimal architecture of a neural network. There are different approaches to NAS, and one popular method is using reinforcement learning.
Here is an example code using the AutoKeras library, which implements NAS using reinforcement learning:
main.py587 chars20 lines
In this example code, we first load a dataset and split it into training and testing data. Then we create an instance of StructuredDataClassifier
from AutoKeras with max_trials=10
, which means we will search for 10 different architectures. We fit the classifier on the training data, and AutoKeras will automatically search for the best neural network architecture using reinforcement learning.
Finally, we evaluate the best neural network found on the testing data using the evaluate
method of the classifier. The score
variable will contain the evaluation result (e.g. accuracy).
Using AutoKeras, we can easily build a self-growing neural network without manually designing the architecture. We only need to specify the type of problem (e.g. classification, regression, etc.) and the input/output format, and AutoKeras will do the rest.
