Development Dataset (Released)

The development dataset for the task is the VISEM dataset containing data from 85 male participants aged 18 years or older. For each participant, we include a set of measurements from a standard semen analysis, a video of live spermatozoa, a sperm fatty acid profile, the fatty acid composition of serum phospholipids, study participants-related data and WHO analysis data. The dataset contains over 35 gigabytes of videos, with each video lasting between two to seven minutes. Each video has a resolution of 640 x 480 and runs at 50 frames-per-second. The dataset contains in total six CSV-files (five for data and one which maps video IDs to study participants IDs), a description file, and a folder containing the videos. The name of each video file contains the videos ID, the date it was recorded, and a small optional description. Then, the end of the filename contains the code of the person who assessed the video. Furthermore, VISEM contains five CSV-files for each of the other data provided, a CSV-file with the IDs linked to each their video, and a text file containing descriptions of some of the columns of the CSV-files. One row in each CSV-file represents a participant. The provided CSV-files are:

• semen_analysis_data.csv: The results of standard semen analysis.
• fatty_acids_spermatozoa.csv: The levels of several fatty acids in the spermatozoa of the participants.
• fatty_acids_serum.csv: The serum levels of the fatty acids of the phospholipids (measured from the blood of the participant).
• sex_hormones.csv: The serum levels of sex hormones measured in the blood of the participants.
• study_participant_related_data.csv: General information about the participants such as age, abstinence time and Body Mass Index (BMI).
• videos.csv: Overview of which video-file belongs to what participants.

The following files are provided in the Development dataset:

• Development dataset archive contains sets of videos and associated meta-data for 85 different participants.
• Development dataset features archive contains the extracted visual feature descriptors for all videos (from the first 2 frames of every second).

Test Dataset (Released)

The following files are provided in the Test dataset:

• Test dataset archive contains sets of videos and associated meta-data for 85 different participants split into three folds for three-fold cross-validation.
• Test dataset features archive contains the extracted visual feature descriptors for all videos (from the first 2 frames of every second) split into three folds for three-fold cross-validation.
