How I pick features for credit scoring models in Python: Kruskal-Wallis for continuous variables, Cramer’s V for categorical ones, and Spearman rank correlation to catch redundant pairs before any training starts.
Machine learning projects fail on planning more often than on algorithms. What works for me: chase approvals early, block real hours for the main pipeline, and stop repointing the stack every time a new model ships.
Notes from the Dev Chat on WordPress 7.0: the AI Client and Connectors API, why the release cycle got extended, the left navigation rethink, and the argument over YouTube support in the Cover block.
Products drift when nobody writes down what they stand for. How Dieter Rams’ principles helped me kill an upsell on a WooCommerce checkout, plus the workshop and the CSS variables I use to keep principles in the code.
WordPress 7.0 brings AI into core through the AI Client and the Abilities API. Here is what wp_ai_client_prompt() actually does, how to test it now, and what the Core AI team will work on during Contributor Day at WordCamp Asia 2026 in Mumbai.
DenseNet connects every layer to every later layer and stacks channels instead of summing them the way ResNet does. Why that helps with vanishing gradients, how bottleneck blocks and transition layers keep the tensors in check, and where the memory cost shows up in PyTorch.
Frontier models stack a huge symbolic layer on an absent physical base, what Peter Zakrzewski calls the inversion error. The case for an enactive floor and for treating state-space reversibility as a hard constraint instead of an alignment patch.
Most QML writeups skip past encoding. This one goes through basis, angle and amplitude encoding plus feature maps, and what each one costs you in qubits or circuit depth on current hardware.
SHAP adds roughly 30ms to every prediction, which is fine offline and useless in a live request. Here is the neuro-symbolic alternative I benchmarked at 0.89ms, plus the weight collapse problem you run into on the way there.
The AI Client and Connectors API change how plugins talk to an LLM in WordPress 7.0. Notes from the Dev Chat agenda, plus the PHP refactor from a hardcoded wp_remote_post call to a registered ability.
