Introduction

In recent years, the field of natural language processing (NLP) has witnessed significant advancements, particularly in the realm of transformer-based models. One of the key challenges in NLP is the evaluation of complex tasks, such as those involving multiple components or operations. To address this challenge, researchers have proposed various evaluation metrics, including the CoT (Component Task) evaluation. In this article, we will explore the concept of CoT 'splicing' evaluation and its implementation in the task_shortening.py file.

What is CoT 'Splicing' Evaluation?

CoT 'splicing' evaluation is a technique used to assess the performance of a model on a specific task by splicing or inserting a CoT into the task prompt. A CoT is a component or operation that is essential to the task, and by evaluating the model's performance on this component, we can gain insights into its ability to perform the task as a whole. The CoT 'splicing' evaluation involves the following steps:

Selecting the CoT: The first step is to select the CoT that will be used for evaluation. This CoT should be a critical component of the task and should be representative of the task as a whole.
Splicing the CoT: Once the CoT has been selected, it is spliced or inserted into the task prompt. This is typically done by concatenating the CoT with the task prompt.
Evaluating the model: The model is then evaluated on the spliced task prompt. This evaluation is typically done using a specific metric, such as accuracy or F1 score.

Implementation in `task_shortening.py`

To implement the CoT 'splicing' evaluation in the task_shortening.py file, we need to make the following changes:

Asserting LoRA Training

The first change we need to make is to assert that models trained on this py file are always trained with LoRA. This can be done using the following code:

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

# Load the pre-trained model and tokenizer
model_name = "bert-base-uncased"
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Assert that the model is trained with LoRA
assert model.config.gradient_checkpointing, "Model must be trained with LoRA"

Splicing the CoT

The next step is to splice the CoT into the task prompt. This can be done using the following code:

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

# Load the pre-trained model and tokenizer
model_name = "bert-base-uncased"
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Define the CoT
cot = "This is the CoT"

# Define the task prompt
task_prompt = "This is the task prompt"

# Splice the CoT into the task prompt
spliced_task_prompt = cot + " " + task_prompt

# Preprocess the spliced task prompt
inputs = tokenizer(spliced_task_prompt, return_tensors="pt")

Evaluating the Model

The final step is to evaluate the model on the spliced task prompt. This can be done using the following code:

import torch
from transformers import AutoModelForSequenceClassification, AutoTokenizer

# Load the pre-trained model and tokenizer
model_name = "bert-base-uncased"
model = AutoModelForSequenceClassification.from_pretrained(model_name)
tokenizer = AutoTokenizer.from_pretrained(model_name)

# Define the CoT
cot = "This is the CoT"

# Define the task prompt
task_prompt = "This is the task prompt"

# Splice the CoT into the task prompt
spliced_task_prompt = cot + " " + task_prompt

# Preprocess the spliced task prompt
inputs = tokenizer(spliced_task_prompt, return_tensors="pt")

# Evaluate the model on the spliced task prompt
outputs = model(**inputs)

Reporting the Results

The final step is to report the results of the CoT 'splicing' evaluation. This can be done using the following code:

import wandb

# Initialize the wandb logger
wandb.init(project="cot-splicing-evaluation")

# Report the results
wandb.log({"cot_splicing_evaluation": outputs})

Conclusion

In this article, we explored the concept of CoT 'splicing' evaluation and its implementation in the task_shortening.py file. We demonstrated how to assert that models trained on this py file are always trained with LoRA, splice the CoT into the task prompt, evaluate the model on the spliced task prompt, and report the results using wandb. This technique can be used to assess the performance of a model on a specific task by evaluating its ability to perform a critical component of the task.

Future Work

There are several potential future directions for this work. One possible direction is to explore the use of CoT 'splicing' evaluation in other NLP tasks, such as question answering or text classification. Another possible direction is to investigate the use of CoT 'splicing' evaluation in conjunction with other evaluation metrics, such as accuracy or F1 score.
