Usage:

# enable model auto update, the default is false
lgbm-auto-update: true
# model auto update interval, the default is 72 (hours)
lgbm-update-interval: 72
# model update url
lgbm-url: "https://github.com/vernesong/mihomo/releases/download/LightGBM-Model/Model.bin"

profile:
  #smart-collector-size: data collection file size, the default is 100 (MB)
  smart-collector-size: 100

proxy-groups:
- name: Smart Group
  type: smart
  # policy-priority: <1 means lower priority, >1 means higher priority, the default is 1, pattern support regex and string
  policy-priority: "Premium:0.9;SG:1.3" 
  # uselightgbm: use LightGBM model predict weight
  uselightgbm: false
  # collectdata: collect datas for model training
  collectdata: false
  # sample-rate: data acquisition rate, desirable values are 0-1, the default is 1
  sample-rate: 1
  # prefer-asn: force and lookup asn first when nodes select, the default is false
  prefer-asn: true
  ...

• LightGBM for weight prediction (option: uselightgbm: true)，need Model.bin file exist HomeDir (.config/mihomo/Model.bin) or use in OpenClash: (/etc/openclash/Model.bin)
• Data collection function to facilitate for yourself-training of weight prediction models (option: collectdata: true), path in HomeDir (.config/mihomo/smart_weight_data.csv) or (/etc/openclash/smart_weight_data.csv) in OpenClash
• If you need to train the model yourself, you could use feature transforms and must training by LightGBM version 3.3.5
