Research Type Experimental We investigate the performance of Gros To T on a largescale micro-blog dataset consisting of 14M posts generated by 0.52M users, spanning three months period, from Dec 2012 to Feb 2013. Cros Tot shows significant improvement over state-of-the-art temporal modeling methods. Our proposed approach shows advantage not only in temporal dynamics but also group content modeling.

Pseudocode No The paper describes the generative process and model inference steps in paragraph and equation form, but does not include a formally labeled 'Pseudocode' or 'Algorithm' block or figure.
Open Source Code No The paper does not provide any concrete access information (e.g., specific repository link, explicit code release statement, or code in supplementary materials) for the described methodology.
Open Datasets No We use a large real dataset crawled from Sina Weibo2, one of the most popular micro-blog platforms. We randomly sample users and get their streaming updates.
Dataset Splits No The paper states 'We randomly select 80% tweets as the training set while the remaining 20% as testing set,' but does not specify a separate validation dataset or split.
Hardware Specification No The paper does not provide specific details about the hardware used for running the experiments (e.g., CPU/GPU models, memory specifications).
Software Dependencies No The paper does not provide specific software dependencies with version numbers (e.g., library names with versions like Python 3.8, PyTorch 1.9).
Experiment Setup Yes For simplicity we fix the hyperparameters to β = λ = 0.01, δ = 50/C and α = 50/K. For clarity we fix K = 100 and G = 100 in the following study.
