43360 Global exporters importers export import shipment records of Jigsaw puzzles with prices, volume & current Buyer's suppliers relationships based on actual Global export trade database.

These maps have been created using cadmapper, and they are used to test the jigsaw puzzle solver algorithm on real data.

The jigsaw puzzle solver approach is described in the paper:

Nash Meets Wertheimer: Using Good Continuation in Jigsaw Puzzles, Khoroshiltseva et al., ACCV 2024.

The data here are 13 maps (in .dxf format) and the relative rendered images. In the paper the vector data was extracted from the .dxf file and the images used for color-based puzzle solving are the ones provided here.

As part of the original data comes from Openstreetmaps, we release it the Open Database License (in the License.txt the other sources are also mentioned, generated from cadmapper).

Dataset Card for Lichess Puzzles

  Dataset Description

5,036,915 chess puzzles, rated and tagged. See them in action on Lichess. This dataset is updated monthly, and was last updated on July 2nd, 2025.

  Dataset Creation

Generating the initial dataset chess puzzles took more than 50 years of CPU time. We went through 300,000,000 analyzed games from the Lichess database, and re-analyzed interesting positions with Stockfish 12/13/14/15 NNUE at 40 meganodes.

The JHU-ISI Gesture and Skill Assessment Working Set (JIGSAWS) is a surgical activity dataset for human motion modeling. The data was collected through a collaboration between The Johns Hopkins University (JHU) and Intuitive Surgical, Inc. (Sunnyvale, CA. ISI) within an IRB-approved study. The release of this dataset has been approved by the Johns Hopkins University IRB. The dataset was captured using the da Vinci Surgical System from eight surgeons with different levels of skill performing five repetitions of three elementary surgical tasks on a bench-top model: suturing, knot-tying and needle-passing, which are standard components of most surgical skills training curricula. The JIGSAWS dataset consists of three components:

kinematic data: Cartesian positions, orientations, velocities, angular velocities and gripper angle describing the motion of the manipulators. video data: stereo video captured from the endoscopic camera. Sample videos of the JIGSAWS tasks can be downloaded from the official webpage. manual annotations including: gesture (atomic surgical activity segment labels). skill (global rating score using modified objective structured assessments of technical skills). experimental setup: a standardized cross-validation experimental setup that can be used to evaluate automatic surgical gesture recognition and skill assessment methods.

This database contains the 166 Galvanic Skin Response (GSR) signal registers collected from the subjects participating in the first experiment (EXP 1) presented in:R. Martinez, A. Salazar-Ramirez, A. Arruti, E. Irigoyen, J. I. Martin and J. Muguerza, "A Self-Paced Relaxation Response Detection System Based on Galvanic Skin Response Analysis," in IEEE Access, vol. 7, pp. 43730-43741, 2019. doi: 10.1109/ACCESS.2019.2908445In addition to the files containing the GSR signals, for each subject there is an extra file. The labels given by the experts to the Relaxation Responses (RResp) can be found in these extra files, along with the central window time in which these labels were given. There are four RResp intensity levels: 0 stands for the absence of any RResp, -1 for a Low intensity RResp, -2 for a Medium intensity RResp and -3 for a High intensity RResp.

Lichess Puzzle Embeddings (ChessLM Encoder v4)

  Dataset Description

This dataset contains pre-computed vector embeddings for chess puzzle positions sourced from the Lichess Open Puzzle Database. The embeddings were generated using the odestorm1/chesslm (https://huggingface.co/datasets/odestorm1/chesslm_puzzles) Encoder Transformer model. Each row corresponds to a unique chess puzzle, providing its initial FEN (Forsyth–Edwards Notation) string, the sequence of moves in the… See the full description on the dataset page: https://huggingface.co/datasets/odestorm1/chesslm_puzzles.
