MatchZoo-py

PyTorch version of MatchZoo.

Facilitating the design, comparison and sharing of deep text matching models.

MatchZoo 是一个通用的文本匹配工具包，它旨在方便大家快速的实现、比较、以及分享最新的深度文本匹配模型。

The goal of MatchZoo is to provide a high-quality codebase for deep text matching research, such as document retrieval, question answering, conversational response ranking, and paraphrase identification. With the unified data processing pipeline, simplified model configuration and automatic hyper-parameters tunning features equipped, MatchZoo is flexible and easy to use.

To train a Deep Semantic Structured Model, make use of MatchZoo customized loss functions and evaluation metrics to define a task:

import torch
import matchzoo as mz

ranking_task = mz.tasks.Ranking(losses=mz.losses.RankCrossEntropyLoss(num_neg=4))
ranking_task.metrics = [
    mz.metrics.NormalizedDiscountedCumulativeGain(k=3),
    mz.metrics.MeanAveragePrecision()
]

Prepare input data:

train_pack = mz.datasets.wiki_qa.load_data('train', task=ranking_task)
valid_pack = mz.datasets.wiki_qa.load_data('dev', task=ranking_task)

Preprocess your input data in three lines of code, keep track parameters to be passed into the model:

preprocessor = mz.models.ArcI.get_default_preprocessor()
train_processed = preprocessor.fit_transform(train_pack)
valid_processed = preprocessor.transform(valid_pack)

Generate pair-wise training data on-the-fly:

trainset = mz.dataloader.Dataset(
    data_pack=train_processed,
    mode='pair',
    num_dup=1,
    num_neg=4,
    batch_size=32
)
validset = mz.dataloader.Dataset(
    data_pack=valid_processed,
    mode='point',
    batch_size=32
)

Define padding callback and generate data loader:

padding_callback = mz.models.ArcI.get_default_padding_callback()

trainloader = mz.dataloader.DataLoader(
    dataset=trainset,
    stage='train',
    callback=padding_callback
)
validloader = mz.dataloader.DataLoader(
    dataset=validset,
    stage='dev',
    callback=padding_callback
)

Initialize the model, fine-tune the hyper-parameters:

model = mz.models.ArcI()
model.params['task'] = ranking_task
model.params['embedding_output_dim'] = 100
model.params['embedding_input_dim'] = preprocessor.context['embedding_input_dim']
model.guess_and_fill_missing_params()
model.build()

Trainer is used to control the training flow:

optimizer = torch.optim.Adam(model.parameters())

trainer = mz.trainers.Trainer(
    model=model,
    optimizer=optimizer,
    trainloader=trainloader,
    validloader=validloader,
    epochs=10
)

trainer.run()
