Pull Request for DL-Simplified 💡

Issue Title : Online Food Delivery Preferences

• Info about the related issue (Aim of the project) : The project focuses on two primary objectives:

Predict whether customers will place future orders using CNN, RNN, and a hybrid RNN+LSTM model based on demographic data such as age, occupation, monthly income, and family size.
Perform sentiment analysis on customer reviews to better understand customer experiences, using DNN, LSTM, and GRU models to classify the reviews as positive or negative.

Closes: #793

Describe the add-ons or changes you've made 📃

1. Data Preprocessing:
   -Removed missing and irrelevant data (e.g., 'Nil' reviews).
   -Tokenized reviews and converted them into sequences suitable for deep learning models.

2. Exploratory Data Analysis (EDA):
   -Analyzed the distribution of customer demographics such as age, income, family size etc.
   -Created visualizations like bar charts and word clouds for reviews to understand sentiment polarity.

3. Model Implementation for Prediction:
   -Built CNN, RNN, and RNN+LSTM models to predict customer reordering behavior.
   -Experimented with different architectures to capture patterns in structured data.

4. Model Implementation for Sentiment Analysis:
   -Developed DNN, LSTM, and GRU models for customer review analysis.
   -These models were optimized to handle varying text lengths and interpret user sentiment effectively.

5. Evaluation and Comparison:
   -Compared models using accuracy, precision, recall, and F1-score.
   -Identified the most accurate models for each task.
