Research Type Experimental We evaluate Comb Cascade on two real-world problems and show that it performs well even when our modeling assumptions are violated. We also demonstrate that our setting requires a new learning algorithm. We evaluate Comb Cascade in three experiments. In Section 4.1, we compare it to Comb UCB1 [12], a state-of-the-art algorithm for stochastic combinatorial semi-bandits with a linear reward function. This experiment shows that Comb UCB1 cannot solve all instances of our problem, which highlights the need for a new learning algorithm. It also shows the limitations of Comb Cascade. We evaluate Comb Cascade on two real-world problems in Sections 4.2 and 4.3.

Pseudocode Yes Algorithm 1 Comb Cascade for combinatorial cascading bandits.
Open Source Code No The paper does not provide a link or explicit statement about releasing the source code for their proposed method or experiments.
Open Datasets Yes We experiment with the Movie Lens dataset [13] from March 2015.
Dataset Splits No The paper uses the Movie Lens dataset but does not specify exact training, validation, or test splits (e.g., percentages or sample counts).
Hardware Specification No The paper does not provide any specific hardware details such as GPU or CPU models, or cloud computing instance types used for running the experiments.
Software Dependencies No The paper does not specify any software dependencies with version numbers (e.g., programming languages, libraries, or frameworks with their versions) used in the experiments.
Experiment Setup No While the paper describes the problem settings and general experiment configurations (e.g., network structure, dataset filtering), it does not explicitly provide specific hyperparameters or system-level training settings for the Comb Cascade algorithm (e.g., learning rates, batch sizes, number of epochs, or optimizer settings).
