| Pseudocode | Yes | Algorithm 1 Deep Representation and Shallow Exploration (Neural-Lin UCB) ... Algorithm 2 Update Weight Parameters with Gradient Descent |
| Open Source Code | No | The paper does not provide a statement or link for open-sourcing the code. |
| Open Datasets | Yes | Specifically, following the experimental setting in Zhou et al. (2020),we use datasets (Shuttle) Statlog, Magic and Covertype from UCI machine learning repository (Dua & Graff, 2017), and the MINST dataset from Le Cun et al. (1998). |
| Dataset Splits | No | The paper mentions using |
| Hardware Specification | Yes | All numerical experiments were run on a workstation with Intel(R) Xeon(R) CPU E5-2637 v4 @ 3.50GHz. |
| Software Dependencies | No | The paper mentions using 'Re LU neural network' and 'stochastic gradient decent' but does not specify software versions for libraries like PyTorch, TensorFlow, or scikit-learn. |
| Experiment Setup | Yes | We use a Re LU neural network defined as in (2.3) with L = 2 and m = 100 for the UCI datasets (Statlog, Magic, Covertype). ... We set the time horizon T = 15, 000... We use stochastic gradient decent to optimize the network weights, with a step size ηq =1e-5 and maximum iteration number n = 1, 000. ... the network parameter w is updated every H = 100 rounds... We set λ = 1 and αt = 0.02 for all algorithms, t [T]. |
