What is kernelshap?

kernelshap makes permutation SHAP practical past eight features, then fixes the kernel weights it had wrong.

kernelshap computes model-agnostic SHAP values in R through Kernel SHAP, permutation SHAP and an exact additive explainer. Version 0.8.0 added a sampling permutation-SHAP algorithm with standard errors and early stopping, lifting the practical feature ceiling past what the exact method allows. Version 0.9.0 then corrected a bug in how kernel weights were computed — exact Kernel SHAP now agrees with exact permutation SHAP — and moved parallelism from foreach to doFuture.

What is npi?

An R client for the US provider registry, tightening its types and edge-case handling

npi wraps the US National Provider Identifier registry API for R users, covering search, validation and summarisation of provider records. The one release in view is a consolidation pass rather than new surface: input normalisation, vectorised validation, and a typed empty result instead of an ambiguous one when a search finds nothing.

kernelshap makes permutation SHAP practical past eight features, then fixes the kernel weights it had wrong.

◆ Current state

kernelshap computes model-agnostic SHAP values in R through Kernel SHAP, permutation SHAP and an exact additive explainer. Version 0.8.0 added a sampling permutation-SHAP algorithm with standard errors and early stopping, lifting the practical feature ceiling past what the exact method allows. Version 0.9.0 then corrected a bug in how kernel weights were computed — exact Kernel SHAP now agrees with exact permutation SHAP — and moved parallelism from foreach to doFuture.

◆ Where it's heading

Two concerns drive this package: making exact methods reach further, and being demonstrably right. The first shows in the additive explainer, the optional background dataset and the sampling permutation algorithm; the second in unit tests written against Python's shap, credited fixes from outside contributors, and a willingness to ship a correctness fix that changes numbers people have already published. Speed work runs continuously underneath — direct solves replacing the Moore-Penrose pseudo-inverse, roughly 10% less memory.

◆ Prediction

The 0.6.0 and 0.7.0 notes each promised a stable 1.0.0 that has not arrived; with the weighting bug fixed and parallelism reworked, a 1.0 release is the most plausible next step.

An R client for the US provider registry, tightening its types and edge-case handling

◆ Current state

npi wraps the US National Provider Identifier registry API for R users, covering search, validation and summarisation of provider records. The one release in view is a consolidation pass rather than new surface: input normalisation, vectorised validation, and a typed empty result instead of an ambiguous one when a search finds nothing.

◆ Where it's heading

The work is aimed at making the package behave predictably inside larger pipelines. Returning a typed empty `npi_results` object on no matches, and having `npi_is_valid()` accept vectors and return logical vectors, both remove branches a caller would otherwise write by hand. The bug fix follows the same line — `npi_summarize()` no longer drops input rows when a record's nested address or taxonomy data is missing.

◆ Prediction

With a single release visible there is not enough of a pattern to predict a direction confidently; the changes here suggest continued interface tidying rather than new API coverage, but that is one data point.

Frequently asked questions

What is the difference between kernelshap and npi?

They serve adjacent needs but don't currently overlap on shipped themes. kernelshap and npi are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.

Is kernelshap better than npi?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. kernelshap and npi are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
