2020年4月30日 · We introduce negative binomial matrix factorization (NBMF), a matrix factorization technique specially designed for analyzing over-dispersed count data. It can be viewed as an extension of Poisson factorization (PF) perturbed by a multiplicative term which models exposure.

我们引入负二项式矩阵分解（NBMF），这是一种专为分析过度分散计数数据而设计的矩阵分解技术。 它可以被视为泊松分解 (PF) 的扩展，受到模拟暴露的乘法项的扰动。

main_script.py trains the models (NBMF-EM, NBMF-MM, and logPCA) while performing validation (minimize perplexity on the validation set), to tune the hyperparameters. It also predict the test data with various random initializations.

2024年11月18日 · nbmf属于协同过滤中的一种，尤其是模型基础协同过滤方法，它可以处理用户或物品的缺失数据，为每个用户和物品生成隐因子表示。 4. Python编程语言： Python是一种高级编程语言，由于其简洁的语法和强大的库支持，成为了数据科学和机器学习领域的首选语言之一。 Python拥有大量用于科学计算和数据分析的库，比如NumPy、SciPy、Pandas和Scikit-learn，这些库支持负二项式矩阵分解算法的实现。 在Python环境下，开发者可以方便地利用这些工具实 …

Nonnegative/binary matrix factorization (NBMF) was originally introduced as a generative model, and we propose a multiclass classification model as an application. We extract the...
