Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

Research Type Experimental To uncover the pre-activation dimension of high-dimensional activity in visual cortex, we perform two-photon calcium recordings of tens of thousands of neurons from mouse visual cortex, and infer the pre-activation dimension using the Neural Cross-Encoder (NCE), an interpretable, nonlinear latent variable modeling method which models the activity of each neuron as a simple linear-nonlinear readout of low-dimensional latents.

Pseudocode No The paper describes methods and derivations in narrative text and mathematical equations throughout the main body and appendices, but it does not include any explicitly labeled 'Pseudocode' or 'Algorithm' blocks or figures.
Open Source Code Yes All data and code used to train the NCE and generate the results, as well as code used for simulations in Fig. 2, are shared via Figshare: https://figshare.com/s/aac82eac1829b7ec406e and Github: https://github.com/alihaydaroglu/NCE.
Open Datasets Yes All data and code used to train the NCE and generate the results, as well as code used for simulations in Fig. 2, are shared via Figshare: https://figshare.com/s/aac82eac1829b7ec406e and Github: https://github.com/alihaydaroglu/NCE. Preprocessed neural datasets, comprised of deconvolved spontaneous activity and averaged, deconvolved stimulus responses, is also anonymized and submitted with the supplementary materials.
Dataset Splits Yes In all three conditions, the paired source-target datasets were split into train-validation-test sets with a 50%-20%-30% split.
Hardware Specification Yes Volumetric calcium movies were processed using a custom workstation running Ubuntu 20.04.6 LTS with an Intel(R) Xeon(R) w9-3475X CPU (36 cores, 2.20 GHz), NVIDIA RTX A4500 GPU (20GB VRAM), and 512 GB DDR5 RAM. ... All NCE experiments were performed on a workstation running Windows 10 Pro, with an Intel (R) Core(TM) i7-11700k CPU (8 cores, 3.6 GHz), NVIDIA RTX 3060 GPU (12GB VRAM), and 128 GB DDR4 RAM.
Software Dependencies No This work makes use of several publicly available software resources including: Python (PSF License), Matplotlib (PSF License), NumPy (BSD License), SciPy (BSD License), CuPy (MIT License), PyTorch (BSD-3 License), Suite3D (AGPL-3 License).
Experiment Setup Yes parameters were optimized through stochastic gradient descent using Adam [96] and a batch size of 2,048, with a learning rate of 10 3, momentum parameters β1 = 0.85, β2 = 0.95, and an L2 penalty of 10 5. Model parameters were randomly initialized with Kaiming initialization [97].
