An error when modeling FastICA algorithm

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NotEnoughSamples

When there are no samples in the provided dataset

InvalidValue(String)

When any of the hyperparameters are set the wrong value

SvdDecomposition

If we fail to compute any components of the SVD decomposition due to an Ill-Conditioned matrix

InvalidTolerance(f32)

LinalgError(LinalgError)

Errors encountered during linear algebra operations

LinfaError(Error)

Trait Implementations

impl Debug for FastIcaError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for FastIcaError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for FastIcaError

fn source(&self) -> Option<&(dyn Error + 'static)>

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<F: Float, D: Data<Elem = F>, T> Fit<ArrayBase<D, Dim<[usize; 2]>>, T, FastIcaError> for FastIcaValidParams<F>

fn fit(
    &self,
    dataset: &DatasetBase<ArrayBase<D, Ix2>, T>
) -> Result<Self::Object>

Fit the model

Errors

If the FastIcaValidParams::ncomponents is set to a number greater than the minimum of the number of rows and columns

If the alpha value set for GFunc::Logcosh is not between 1 and 2 inclusive

type Object = FastIca<F>
