Usage

For detailed usage instructions, please see the Documentation.

To use the package, you must:

1. Load Rocketeer,
2. Create a RocketModule object (with optionally specified input_length and n_kernels hyperparameters),
3. apply_kernels to your dataset to extract the Rocket features,
4. Optionally save_rocket and load_rocket if you intend to utilize the exact same kernels in future experiments.

For example:

# Load the module
using Rocketeer

# Set some parameters of the example
filepath = "my_rocket"  # Point to a save file
input_length = 10       # The length of the input window
n_kernels = 200         # The number of kernels to generate

# Create a rocket module
my_rocket = RocketModule(input_length, n_kernels)

# Save it for future use
save_rocket(my_rocket, filepath)

# Load the module back into a new object
my_new_rocket = load_rocket(filepath)

# Create some random data
X = rand(input_length)

# Apply the kernels to get features
features = apply_kernels(my_new_rocket, X)
