The integration involves utilizing LlamaIndex's generate_question_context_pairs module to create relevant question and context pairs, forming the foundation for retrieval and response evaluation in the RAG system.

To assess the retriever's effectiveness, LangTest introduces LangtestRetrieverEvaluator, employing key metrics such as Hit Rate and Mean Reciprocal Rank (MRR). Hit Rate gauges the precision by assessing the percentage of queries with the correct answer in the top-k retrieved documents. MRR evaluates the accuracy by considering the rank of the highest-placed relevant document across all queries. This comprehensive evaluation, using both standard and perturbed queries generated through LangTest, ensures a thorough understanding of the retriever's robustness and adaptability under various conditions, reflecting its real-world performance.

from langtest.evaluation import LangtestRetrieverEvaluator

retriever_evaluator = LangtestRetrieverEvaluator.from_metric_names(
    ["mrr", "hit_rate"], retriever=retriever
)
     
retriever_evaluator.setPerturbations("add_typo","dyslexia_word_swap", "add_ocr_typo") 

# Evaluate
eval_results = await retriever_evaluator.aevaluate_dataset(qa_dataset)

retriever_evaluator.display_results()

📚Grammar Testing in Evaluating and Enhancing NLP Models

Grammar Testing is a key feature in LangTest's suite of evaluation strategies, emphasizing the assessment of a language model's proficiency in contextual understanding and nuance interpretation. By creating test cases that paraphrase original sentences, the goal is to gauge the model's ability to comprehend and interpret text, thereby enriching insights into its contextual mastery.

Category	Test Type	Original	Test Case	Expected Result	Actual Result	Pass
grammar	paraphrase	This program was on for a brief period when I was a kid, I remember watching it whilst eating fish and chips. Riding on the back of the Tron hype this series was much in the style of streethawk, manimal and the like, except more computery. There was a geeky kid who's computer somehow created this guy - automan. He'd go around solving crimes and the lot. All I really remember was his fancy car and the little flashy cursor thing that used to draw the car and help him out generally. When I mention it to anyone they can remember very little too. Was it real or maybe a dream?	I remember watching a show from my youth that had a Tron theme, with a nerdy kid driving around with a little flashy cursor and solving everyday problems. Was it a genuine story or a mere dream come true?	NEGATIVE	POSITIVE	false

🔥 Saving and Loading the Checkpoints

Introducing a robust checkpointing system in LangTest! The run method in the Harness class now supports checkpointing, allowing users to save intermediate results, manage batch processing, and specify a directory for storing checkpoints and results. This feature ensures data integrity, providing a mechanism for recovering progress in case of interruptions or task failures.

harness.run(checkpoint=True, batch_size=20,save_checkpoints_dir="imdb-checkpoint")

The load_checkpoints method facilitates the direct loading of saved checkpoints and data, providing a convenient mechanism to resume testing tasks from the point where they were previously interrupted, even in the event of runtime failures or errors.

harness = Harness.load_checkpoints(save_checkpoints_dir="imdb-checkpoint",
                                   task="text-classification",
                                   model = {"model": "lvwerra/distilbert-imdb" , "hub":"huggingface"}, )

LangTest effectively leverages this capability by incorporating an automatic testing callback. This class is both flexible and adaptable, seamlessly integrating with any transformers model for a customized experience.

Create a callback instance with one line and then use it in the callbacks of trainer:

my_callback = LangTestCallback(...)
trainer = Trainer(..., callbacks=[my_callback])

Parameter	Description
task	Task for which the model is to be evaluated (text-classification or ner)
data	The data to be used for evaluation. A dictionary providing flexibility and options for data sources. It should include the following keys: data_source (mandatory): The source of the data. subset (optional): The subset of the data. feature_column (optional): The column containing the features. target_column (optional): The column containing the target labels. split (optional): The data split to be used. source (optional): Set to 'huggingface' when loading Hugging Face dataset.
config	Configuration for the tests to be performed, specified in the form of a YAML file.
print_reports	A bool value that specifies if the reports should be printed.
save_reports	A bool value that specifies if the reports should be saved.
run_each_epoch	A bool value that specifies if the tests should be run after each epoch or the at the end of training

🚀 Enhanced Templatic Augmentation with Automated Sample Generation

Users can now enable the automatic generation of sample templates by setting generate_templates to True. This feature utilizes the advanced capabilities of LLMs to create structured templates that can be used for templatic augmentation.To ensure quality and relevance, users can review the generated templates by setting show_templates to True.
