Predictive Analytics with TensorFlow 10.3: Improved Factorization Machines for Predictive Analytics

The video tutorial covers predictive analytics, focusing on factorization machines (FM) and their limitations in modeling feature interactions linearly. It introduces neural factorization machines (NFM) and attentional factorization machines (AFM) as advancements to address these limitations. The tutorial uses MovieLens data for practical implementation, detailing the conversion of categorical variables to binary features and the training of FM and NFM models. It concludes with an evaluation of the models, highlighting the improvements in prediction accuracy.

What is the primary challenge when using one-hot encoding for categorical variables?

• It increases the dimensionality of the data.

• It decreases the accuracy of the model.

• It simplifies the data structure.

• It makes the data non-linear.

Why might factorization machines be insufficient for real-world data?

• They require too much computational power.

• They model feature interactions linearly.

• They are too complex to implement.

• They do not support categorical data.

What advantage does a neural factorization machine have over a traditional factorization machine?

• It requires no preprocessing.

• It captures non-linear feature interactions.

• It models all interactions with the same weight.

• It uses less data.
