TSNEVisualizationConfig
(embeddings_field=None, model=None, patches_field=None, num_dims=2, pca_dims=50, svd_solver='randomized', metric='euclidean', perplexity=30.0, learning_rate=200.0, max_iters=1000, seed=None, verbose=True, **kwargs)¶ Bases:
fiftyone.brain.visualization.VisualizationConfig
Configuration for t-distributed Stochastic Neighbor Embedding (t-SNE) visualization.
See https://scikit-learn.org/stable/modules/generated/sklearn.manifold.TSNE.html for more information about the supported parameters.
- Parameters
embeddings_field (None) – the sample field containing the embeddings, if one was provided
model (None) – the
fiftyone.core.models.Model
or name of the zoo model that was used to compute embeddings, if knownpatches_field (None) – the sample field defining the patches being analyzed, if any
num_dims (2) – the dimension of the visualization space
pca_dims (50) – the number of PCA dimensions to compute prior to running t-SNE. It is highly recommended to reduce the number of dimensions to a reasonable number (e.g. 50) before running t-SNE, as this will suppress some noise and speed up the computation of pairwise distances between samples
svd_solver ("randomized") – the SVD solver to use when performing PCA. Consult the sklearn docmentation for details
metric ("euclidean") – the metric to use when calculating distance between embeddings. Must be a supported value for the
metric
argument ofscipy.spatial.distance.pdist
perplexity (30.0) – the perplexity to use. Perplexity is related to the number of nearest neighbors that is used in other manifold learning algorithms. Larger datasets usually require a larger perplexity. Typical values are in
[5, 50]
learning_rate (200.0) – the learning rate to use. Typical values are in
[10, 1000]
. If the learning rate is too high, the data may look like a ball with any point approximately equidistant from its nearest neighbours. If the learning rate is too low, most points may look compressed in a dense cloud with few outliers. If the cost function gets stuck in a bad local minimum increasing the learning rate may helpmax_iters (1000) – the maximum number of iterations to run. Should be at least 250
seed (None) – a random seed
verbose (True) – whether to log progress
