Reproducibility Variable Result LLM Response
Research Type Experimental Experiments on synthetic data verify our theoretical findings, and demonstrate that our algorithm is robust in highdim spaces. Experiments on Netflix data shows that our anchor-based algorithm is superior to the KT-k NN algorithm and a standard collaborative filter (using the cosinesimilarities to determine neighbors).

Pseudocode Yes Algorithm 1: KT-k NN (it produces incorrect results) and Algorithm 2: Anchor-k NN.
Open Source Code No The paper does not contain any statement or link indicating the availability of its source code.
Open Datasets Yes We examine the performance of Anchork NN using the standard Netflix dataset (?; ?).
Dataset Splits No The paper mentions choosing an "optimal k (chosen by using cross-validations for Ground-Truth-k NN)" but does not specify the splits for training, validation, or testing for its own experiments.
Hardware Specification No The paper does not provide any specific details about the hardware used for running the experiments.
Software Dependencies No The paper does not specify any software dependencies with version numbers.
Experiment Setup No The paper mentions using an "optimal k (chosen by using cross-validations for Ground-Truth-k NN)" and refers to "different k [101, 1601]" and "k = 751" for Ground-truth kNN in experiments. However, it does not provide explicit hyperparameters like learning rates, batch sizes, or other training configurations.
