Because the code is relatively old and more suitable for beginners, it is recommended that after understanding the basic ideas and code of transE, there is no need to delve into every implementation detail of this code. In the future, other more advanced kge methods can be carefully studied

For example, Rotate

1. The code for training and testing is located in the src folder
2. The results of training and testing are in the res folder. After 1001 epochs of training, the loss is about 14000 (in fact, it is basically fixed at 300 epochs).

Just adjust the location of the DATA and save folders, run transe_simplic.py directly

Paper：Translating embeddings for modeling multi-relational data

FB15k.

The meaning of pseudocode is:

Input: The parameters of the input model are the triplet of the training set, entity set E, relationship set L, margin, and vector dimension k

1: Initialization: Initialize the relationship according to the initialization method of 1

2: L2 norm normalization has been performed here, which means dividing by its own L2 norm

3: Similarly, the entity has also been initialized, but here it is not divided by its own L2 norm

4: During the training cycle:

5: Firstly, L2 norm normalization was performed on the entity

6: Take a batch of samples, where Sbatch represents the positive sample, which is the correct triplet

7: Initialize triplet pairs by creating a list for storage

8, 9, 10: The meaning here should be to replace the head or tail entity of the Sbatch with positive samples to construct negative samples, and then put the corresponding positive and negative sample triplets together to form Tbatch

11: Complete the extraction of positive and negative samples

12: Update vectors based on gradient descent

13: End cycle
