Includes the oversampling methods\nSMOTE with boosting (SMOTEWB) by F. Sağlam and M. A. Cengiz\n(2022) , Markov chain SMOTE\n(MCSMOTE) by F. Sağlam and M. A. Cengiz (2025)\n, uncertainty guided\noversampling (UGO) by F. Sağlam and M. A. Cengiz (2026)\n, and bi-directional SMOTE\n(BiSMOTE) by F. Sağlam and U. Yamak (2027)\n, and the data relocation\napproach DatRel by F. Sağlam (2025)\n, which can also be applied to\nsynthetic samples from any other source, together with commonly\nused alternatives such as SMOTE, ADASYN, Borderline-SMOTE,\nSafe-Level-SMOTE, Radius-SMOTE, VS-SMOTE, geometric SMOTE,\nrandom oversampling and undersampling. The methods share the\nsame interface: they take a feature matrix and a factor class\nvariable and return the resampled data together with the\nsynthetic samples. The package also provides performance\nmetrics for imbalanced classification and data complexity\nmeasures of class imbalance, class overlap and noise.", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "LazyData": "true", "VignetteBuilder": "knitr", "Config/testthat/edition": "3", "URL": "https://fatihsaglam.github.io/imbalanceKit/", "Config/roxygen2/version": "8.1.1", "Config/pak/sysreqs": "cmake", "Repository": "https://fatihsaglam.r-universe.dev", "Date/Publication": "2026-11-13 19:46:10 UTC", "RemoteUrl": "https://github.com/fatihsaglam/imbalancekit", "RemoteRef": "HEAD", "RemoteSha": "b3a71b9710cde3e3938f354c5d8652336ade5b09", "NeedsCompilation": "yes", "Packaged": { "Date": "2026-11-14 12:24:47 UTC", "User": "root" }, "Author": "Fatih Saglam [aut, cre] (ORCID:\n)", "Maintainer": "Fatih Saglam ", "_user": "fatihsaglam", "_type": "src", "_file": "imbalanceKit_0.2.0.tar.gz", "_fileid": "https://r2.ropensci.org/2e2afcc6c90d47860ebf85d9f3e153773aa2964e4ccd3a6bf71d5521d1f09b63", "_filesize": 962339, "_sha256": "2e2afcc6c90d47860ebf85d9f3e153773aa2964e4ccd3a6bf71d5521d1f09b63", "_expires": "2027-02-22T12:29:50.000Z", "_created": "2026-11-14T12:24:47.000Z", "_published": "2026-11-14T12:29:51.997Z", "_upstream": "https://github.com/fatihsaglam/imbalancekit", "_status": "success", "_maintainer": { "name": "Fatih Saglam", "email": "saglamf89@gmail.com", "login": "fatihsaglam", "orcid": "0000-0002-2084-2008", "description": "", "uuid": 23184548 }, "_jobs": [ { "job": 132446693808, "time": 114, "config": "linux-devel-arm64", "r": "4.7.0", "check": "OK", "artifact": "14113323652" }, { "job": 132446693792, "time": 142, "config": "linux-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "14113454420" }, { "job": 132446693728, "time": 139, "config": "linux-release-arm64", "r": "4.6.2", "check": "OK", "artifact": "14112989840" }, { "job": 132446693764, "time": 144, "config": "linux-release-x86_64", "r": "4.6.2", "check": "OK", "artifact": "14113544110" }, { "job": 132446693919, "time": 134, "config": "macos-oldrel-arm64", "r": "4.5.3", "check": "OK", "artifact": "14113573836" }, { "job": 132446693816, "time": 203, "config": "macos-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "14113084713" }, { "job": 132446693735, "time": 127, "config": "macos-release-arm64", "r": "4.6.2", "check": "OK", "artifact": "14114017405" }, { "job": 132446693770, "time": 237, "config": "macos-release-x86_64", "r": "4.6.2", "check": "OK", "artifact": "14114085787" }, { "job": 132445776277, "time": 219, "config": "source", "r": "4.6.2", "check": "OK", "artifact": "14113084361" }, { "job": 132446693812, "time": 90, "config": "wasm-release", "r": "4.6.0", "check": "OK", "artifact": "14113867754" }, { "job": 132446693922, "time": 231, "config": "windows-devel-arm64", "r": "4.7.0", "check": "OK", "artifact": "14113434743" }, { "job": 132446693806, "time": 263, "config": "windows-devel-x86_64", "r": "4.7.0", "check": "OK", "artifact": "14113828465" }, { "job": 132446693955, "time": 247, "config": "windows-oldrel-x86_64", "r": "4.5.3", "check": "OK", "artifact": "14113544401" }, { "job": 132446694017, "time": 220, "config": "windows-release-arm64", "r": "4.6.2", "check": "OK", "artifact": "14113973015" }, { "job": 132446694064, "time": 236, "config": "windows-release-x86_64", "r": "4.6.2", "check": "OK", "artifact": "14113519404" } ], "_buildurl": "https://github.com/r-universe/fatihsaglam/actions/runs/43594397600", "_commit": { "id": "b3a71b9710cde3e3938f354c5d8652336ade5b09", "author": "fatihsaglam ", "committer": "fatihsaglam ", "message": "Prepare 0.2.0 release and optimize DatRel cover\n\nUpdate release metadata, package documentation, and the getting-started vignette.
