我想请教一个ml-1m知识图谱数据集的配置信息问题

[yunshanlucky]

数据集配置文件中：
entity_kg_num_interval: "[5,inf)"
relation_kg_num_interval: "[5,inf)"
这两个参数修改有什么作用，我尝试修改这两个参数，却并没有发现对数据集和实验有任何影响，感谢回答！

知识图谱数据配置信息如下：

dataset config

field_separator: "\t"
seq_separator: " "
USER_ID_FIELD: user_id
ITEM_ID_FIELD: item_id
RATING_FIELD: rating
HEAD_ENTITY_ID_FIELD: head_id
TAIL_ENTITY_ID_FIELD: tail_id
RELATION_ID_FIELD: relation_id
ENTITY_ID_FIELD: entity_id
NEG_PREFIX: neg_
LABEL_FIELD: label
load_col:
inter: [user_id, item_id, rating]
kg: [head_id, relation_id, tail_id]
link: [item_id, entity_id]

data filtering for interactions

val_interval:
rating: "[3,inf)"
unused_col:
inter: [rating]

user_inter_num_interval: "[10,inf)"
item_inter_num_interval: "[10,inf)"

data preprocessing for knowledge graph triples

kg_reverse_r: True
entity_kg_num_interval: "[5,inf)"
relation_kg_num_interval: "[5,inf)"

training and evaluation

epochs: 500
train_batch_size: 4096
eval_batch_size: 40960000
valid_metric: NDCG@10
train_neg_sample_args:
distribution: uniform
sample_num: 1
dynamic: False

这个参数应该类似于user_inter_num_interval和item_inter_num_interval，用来过滤掉 度(节点,实体) 或者 数量(边,关系) 不在这个区间内的点或边。

你修改的应该是sample.yaml里的entity_kg_num_interval和relation_kg_num_interval，但sample.yaml里的kg参数好像不起作用，实际起作用的是./recbole/properties/quick_start_config/knowledge_base.yaml里的参数，可以尝试一下~
