Python

Bag of Projects

A repository filled with several Machine Learning, Deep Learning, and even Data Analysis projects I have completed. The primary goal of this repository is to demonstrate a variety of algorithms and techniques. Each finalized project will also include a text file called "Algorithm Brief" that explains the algorithm or technique used. This repository contains a variety of projects, ranging from small to large in scope (refer to the README for a complete list).

TableNetTable2df

In this project I implemented the TableNet model using PyTorch, the basic idea is to get all sort of documents, convert them to images and then using th emodel detect the tables inside of them, then I crop the tables or jsut hold the coordinates of it.
Next part of it is to fix the gridlines ot be proper gridline and then use pytesseract to extract the tabular data form it and process it into a dataframe.

AutoScraper

This project is made for an automatic web scraping to collect data for machine learning and deep learning projects.
This project have 2 versions Streamlit and FastAPI version (Streamlit is the older one), services include but not limited to: Raw (scraping based on similarities), API downloading, downloading various formats from the website Maya, scraping the web based on user queries, PDF files parsing, Scrape predefined specific content from the OECD website. FastAPI version also include management services like: sending an email, handling tables data in Azure Data Lake, handling Airflow DAGs creation and suitable data in Azure Blob Containers.
The project is using Requests, BeautifulSoup, Scrapy and other libraries.

Chatbot & Virtual-Assistant

Here you will find a collection of implementations of virtual assistants implemented in Python.
Chatbots are intelligent enough to sense the context of the conversation and execute the right bot flow. However, chatbots cannot find answers or perform a set of activities on their own. On the other hand, a virtual assistant can crawl through existing resources and offer assistance for a wide range of requests.

HTTP Client

An HTTP client that constructs an HTTP request based on user’s command line input, sends the request to a Web server, receives the reply from the server, and displays the reply message on screen. (support only IPv4 connections).
For Example:
./client -p some-text -r 2 tel=02-6655443 age=23 http://www.ptsv2.com/t/ex2
The Request would be:
POST /t/ex2?tel=02-6655443&age=23 HTTP/1.0
Host: www.ptsv2.com
Content-length:6

HTTP Server & Thread-pool

HTTP server that:
- Constructs an HTTP response based on client's request.
- Sends the response to the client.
The server creates the pool of threads in advanced and each time it needs a thread to handle a client connection, it take one from the pool or enqueue the request if there is no available thread in the pool.
There is always one socket where the server listens to connections and for each client connection request, the server opens another socket. and let a thread handle it.
