'RsparseMatrix') such as slicing/sub-setting, assignment, rbind(), mathematical operators for CSR and COO such as addition (\"+\") or sqrt(), and methods such as diag(); (b) Multi-threaded matrix multiplication and cross-product for many types, including the 'float32' type from 'float'; (c) Coercion methods between pairs of classes which are not present in 'Matrix', such as 'dgCMatrix' -> 'ngRMatrix', as well as convenience conversion functions; (d) Utility functions for sparse matrices such as sorting the indices or removing zero-valued entries; (e) Fast transposes that work by outputting in the opposite storage format; (f) Faster replacements for many 'Matrix' methods for all sparse types, such as slicing and elementwise multiplication. (g) Convenience functions for sparse objects, such as 'mapSparse' or a shorter 'show' method.","roles",[32],"cph",{"_20":34,"_30":39},{"_22":35,"_24":36,"_26":37,"_28":38},12910,"isotree","Isolation-Based Outlier Detection","Fast and multi-threaded implementation of isolation forest (Liu, Ting, Zhou (2008) <[doi:10.1109/ICDM.2008.17](https://doi.org/10.1109%2FICDM.2008.17)>), extended isolation forest (Hariri, Kind, Brunner (2018) <[doi:10.48550/arXiv.1811.02141](https://doi.org/10.48550/arXiv.1811.02141)>), SCiForest (Liu, Ting, Zhou (2010) <[doi:10.1007/978-3-642-15883-4_18](https://doi.org/10.1007%2F978-3-642-15883-4_18)>), fair-cut forest (Cortes (2021) ), robust random-cut forest (Guha, Mishra, Roy, Schrijvers (2016) <[http://proceedings.mlr.press/v48/guha16.html](http://proceedings.mlr.press/v48/guha16.html)>), and customizable variations of them, for isolation-based outlier detection, clustered outlier detection, distance or similarity approximation (Cortes (2019) <[doi:10.48550/arXiv.1910.12362](https://doi.org/10.48550/arXiv.1910.12362)>), isolation kernel calculation (Ting, Zhu, Zhou (2018) <[doi:10.1145/3219819.3219990](https://doi.org/10.1145%2F3219819.3219990)>), and imputation of missing values (Cortes (2019) <[doi:10.48550/arXiv.1911.06646](https://doi.org/10.48550/arXiv.1911.06646)>), based on random or guided decision tree splitting, and providing different metrics for scoring anomalies based on isolation depth or density (Cortes (2021) <[doi:10.48550/arXiv.2111.11639](https://doi.org/10.48550/arXiv.2111.11639)>).
