KAFYTraj 0.1.16

This library includes an extensible system for building various trajectory operations.

KafyTraj [KAFY] Library

The KafyTraj, KAFY for short, library provides an extensible system for various trajectory operations and includes a versatile command-line interface (CLI) for managing these operations using SQL-like commands. It functions as a toolkit for researchers, facilitating the construction, management, and execution of diverse trajectory operations.

The Meaning Behind the Name “KAFYTraj”

•	KAFY: means sufficient in Arabic.
•	Traj: Short for “Trajectory,” emphasizing the library’s focus on trajectory data processing and analysis.

Features

• Extensible System: Designed to accommodate various trajectory operations with flexibility and ease.
• User-Friendly: Simplifies the construction and management of trajectory operations, making it accessible to researchers.
• SQL-like Command Interface: Allows users to execute trajectory operations through intuitive, SQL-like commands.

Installation

You can install the KAFY library using pip:

pip install KAFYTraj==0.1.15

Usage

To use the library, import the TrajectoryPipeline class from KAFY:

from KAFY import TrajectoryPipeline

# Initialize the pipeline
my_pipeline = TrajectoryPipeline(
    mode="pretraining",
    operation_type="generation",
    use_tokenization=True,
    use_detokenization=True,
    use_spatial_constraints=True,
    modify_spatial_constraints=True,
    use_predefined_spatial_constraints=True,
    project_path="/content/"
)

Defining Project Location

Before starting, you need to define the project location where all project-related data will be saved. This includes directories like modelsRepo, TrajectoryStore, etc. By default, the project location is set to /KafyProject/

If you wish to change the project location permanently, follow these steps:

Step-by-Step Guide to Setting Project Location in bash

1.	Open your terminal.
2.	Open the .bashrc file in a text editor:

>>> nano ~/.bashrc

3.	Add the following line to the end of the file, replacing /new/project/location with your desired directory:

>>> export KAFY_PROJECT_LOCATION=/new/project/location

4.	Save and close the file:
•	In nano, press CTRL + O, hit Enter to confirm, then press CTRL + X to exit.
5.	Apply the changes to your current terminal session:

>>> source ~/.bashrc

Verifying the Change

To verify that the environment variable has been set correctly, run:

>>> echo $KAFY_PROJECT_LOCATION

If everything is correct, this command will output the new project location you set.

SQL-like Command Interface [CLI Based]

To use the SQL-like command interface, you can execute commands directly from the terminal. The CLI allows you to perform operations such as pretraining, fine-tuning, and summarizing data. The librarys is pre-installed into your terminal when you run pip install KafyTraj for the first time.

There are three main stages of using KAFY.

1. PreTraining
2. FineTuning
3. Excution

Pretraining:

In this stage the researcher can:

1. Add a New Dataset for Pretraining You can add a new dataset to the TrajectoryStore to be used for pretraining with all current and future models.

>>> kafy ADD DATA FROM data_source

Example:

>>> kafy ADD DATA FROM 'pretraining_data.csv'

2. Add a New Model or Modify Model Configurations Use available models from HuggingFace’s (HF) Transformers repository by specifying custom configurations.

>>> kafy ADD MODEL transformer_family FROM HF USING model_config_file.json AS model_name_to_be_saved_as

Example: To add a Bert-large model using its configurations:

>>> kafy ADD MODEL bert FROM HF USING bert_large_configs.json AS bert_large

The bert_large model will be added to the TransformersPlugin and will be pretrained on all available pretraining datasets in the TrajectoryStore.

3. Add a Custom Model [Not Implemented For Now] If the model is not available in HuggingFace, you can define your own. Important Note: Custom models should follow the same structure as HuggingFace models. Refer to the examples in the repository for guidance.

>>> kafy ADD MODEL transformer_family FROM model_source USING model_config_file.json AS model_name_to_be_saved_as

Example: To add a model from a custom model definition:

>>> kafy ADD MODEL new_family FROM new_model.py USING new_model_configs.json AS new_model

The new_model model will be added to the TransformersPlugin and will be pretrained on all available pretraining datasets in the TrajectoryStore.

Fine-Tune a Model:

>>> kafy FINETUNE bert FOR summarization USING my_pretrained_model.pkl WITH finetune_config.json AS my_finetuned_model.pkl

Summarize Data:

>>> kafy SUMMARIZE FROM requested_data_to_summarize.csv USING my_finetuned_model.pkl
