SGER: LFM2.5-350M 姓名实体解析与匹配

在 LiquidAI/LFM2.5-350M 基础上分两阶段 LoRA 微调后的合并模型,用于印度 KYC 场景:

  1. 阶段一:噪声姓名解析(还原 first_name / middle_name / last_name,Devanagari 天城文)
  2. 阶段二:二元姓名匹配(判断两个姓名是否指向同一人,输出 Yes/No)

用法

import torch
from transformers import AutoModelForCausalLM, AutoTokenizer

model = AutoModelForCausalLM.from_pretrained(
    "cyqwill/sger-lfm2.5-name-matching",
    torch_dtype=torch.bfloat16,
    device_map="auto",
)
tokenizer = AutoTokenizer.from_pretrained("cyqwill/sger-lfm2.5-name-matching")

prompt = (
    "<|system|>\n"
    "You are an expert system for KYC name matching in India. Determine if Name 1 and Name 2 refer to the same person. "
    "Account for spelling variations, abbreviations, token reordering, merged tokens, and honorifics (-bhai, -ji).\n"
    "<|user|>\n"
    '[Few-Shot Examples]\n'
    'Name 1: "kirtan singh" | Name 2: "singhkirtan" -> Yes\n'
    'Name 1: "ramesh patel" | Name 2: "rameshbhai patel" -> Yes\n'
    'Name 1: "vipin" | Name 2: "bipin" -> No\n'
    '[Target]\n'
    'Name 1: "अनिल रजनी यादव" | Name 2: "रजनी अनिल यादव" -> Match?\n'
    "<|assistant|>\n"
)
inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=8)
print(tokenizer.decode(out[0][inputs.input_ids.shape[-1]:], skip_special_tokens=True))
