There are different ways to implement caching for Machine Learning models, depending on your needs and preferences. One way is to use built-in caching features of some Machine Learning frameworks or libraries, such as TensorFlow, PyTorch, or Scikit-learn. These frameworks or libraries provide functions or decorators that allow you to cache the results of certain operations, such as data loading, preprocessing, or model building. For example, in TensorFlow, you can use the @tf.function decorator to cache the graph of a function that defines a model or a computation. In PyTorch, you can use the torch.utils.data.Dataset class to cache the data that you load from a source. In Scikit-learn, you can use the memory parameter of some estimators or pipelines to cache the intermediate steps of a Machine Learning process.
Another way to implement caching for Machine Learning models is to use external tools or libraries that provide more flexibility and control over the caching process. Some examples of these tools or libraries are Joblib, Dask, or Ray. These tools or libraries allow you to cache the results of any function or task that you define, and store them in memory or disk with different formats and options. For example, in Joblib, you can use the Memory class to create a cache object that can store the output of any function that you decorate with the cache method. In Dask, you can use the persist method to cache the results of any computation that you create with the Dask API. In Ray, you can use the @ray.remote decorator to cache the results of any function or class that you execute in parallel with Ray.
