DAEMONS dataset [Schwetlick et al., 2024].

The DAEMONS paper presents the Potsdam dataset of eye movements on natural scenes, aimed at advancing research in visual cognition and machine learning. It introduces a large-scale dataset with 2,400 images and eye-tracking data from 250 participants, ensuring high-quality data collection using state-of-the-art equipment. The study focuses on both fixation distributions and scan paths, making the dataset valuable for various modeling approaches, including saliency prediction and cognitive modeling.

The dataset is split into train (precomputed_events[0]) and validation (precomputed_events[1]).

Check the respective paper for details [Schwetlick et al., 2024].

name

The name of the dataset.

Type:

str

long_name

The entire name of the dataset.

Type:

str

resources

A list of dataset gaze_resources. Each list entry must be a dictionary with the following keys: - resource: The url suffix of the resource. This will be concatenated with the mirror. - filename: The filename under which the file is saved as. - md5: The MD5 checksum of the respective file.

Type:

ResourceDefinitions

filename_format

Regular expression which will be matched before trying to load the file. Namedgroups will appear in the fileinfo dataframe.

Type:

dict[str, str] | None

filename_format_schema_overrides

If named groups are present in the filename_format, this makes it possible to cast specific named groups to a particular datatype.

Type:

dict[str, dict[str, type]] | None

column_map

The keys are the columns to read, the values are the names to which they should be renamed.

Type:

dict[str, str]

custom_read_kwargs

If specified, these keyword arguments will be passed to the file reading function.

Type:

dict[str, dict[str, Any]]

Examples

Initialize your Dataset object with the SBSAT definition:

>>> import pymovements as pm
>>>
>>> dataset = pm.Dataset("SBSAT", path='data/SBSAT')

Download the dataset resources:

>>> dataset.download()

Load the data into memory:

>>> dataset.load()
