Projects
Face Recognition Using Siamese Network
The Face Recognition Dataset is a collection derived from the Labeled Faces in the Wild (LFW) Dataset, comprising face photographs primarily of famous individuals for face detection and recognition model development. It offers RGB images of 250 x 250 pixels, organized into 1680 directories, each representing a different celebrity with 2 to 50 images per individual. Additionally, the dataset includes an "Extracted Faces" folder, featuring Haar-Cascade-processed 128 x 128 pixel faces for enhanced classifier performance.
Challenges arise from its large number of classes (1678) with limited data per class. To address these challenges, two approaches are explored: Few-Shot Learning, allowing recognition of new classes with minimal labeled examples, and Siamese Models, which learn similarity functions for comparing faces under varying conditions. The most suitable model for facial recognition will be chosen based on accuracy and generalization, using pretrained models within the Siamese Network architecture. For more information, visit the dataset's official website: http://vis-www.cs.umass.edu/lfw/. Proper citation of the LFW dataset and related works is encouraged when using this dataset in research or projects.
Custom OCR
This project focuses on developing an Optical Character Recognition (OCR) system using Seq2Seq models with the aim of finding the best model for OCR through hyperparameter optimization using surrogate functions. Key features optimized include architecture, learning rates, convolution layers, linear layer nodes, growth relationships in convolution layers, memory unit layers, hidden size in memory units, batch size, optimizer, and Seq2Seq models.
The Seq2Seq models are employed for OCR development using the Connectionist Temporal Classification Loss (CTC Loss), which helps align sequences for tasks like audio-to-text. Surrogate functions are used to approximate the best hyperparameters for the model by exploring a search space of hyperparameters and minimizing the loss.
The dataset for training and evaluation can be customized, but a dataset of captcha images is provided for download. The dataset follows specific naming conventions, and the code is provided to create test, train, and validation data folders.
To save the best hyperparameter-trained model, the project provides code for training and saving the model, taking into account the optimized hyperparameters.
Additionally, CTC decoding techniques are mentioned for interpreting the OCR model's outputs. This project aims to build an efficient OCR system with optimized hyperparameters for various OCR tasks.

The provided instructions outline the process of cloning research work, creating TSDFs, and training models. The project references prior work in real-time 3D hand pose estimation using convolutional neural networks.
Sentiment Analysis
This sentiment analysis project utilizes a Kaggle dataset to analyze and predict tweet sentiments as positive or negative. The dataset is sourced from Kaggle and addresses class imbalance. Data augmentation techniques such as synonym replacement and back translation are employed to augment the dataset. Preprocessing steps involve stop word removal, lemmatization, and lowercasing. The dataset is split into training and testing sets, and a Count Vectorizer with a max feature limit is used for feature engineering. The model of choice is Logistic Regression, yielding results detailed in the project. To get started, clone the repository, download the dataset, install necessary libraries, run preprocessing and feature engineering scripts, and train and evaluate the model. The project is open source, and contributions are welcome.
Breast Cancer Detection
This project is focused on breast cancer detection using neural networks. It employs a dataset with 32 columns, including an ID, diagnosis (malignant or benign), and 30 real-valued features derived from digitalized breast mass images. These features describe various characteristics of cell nuclei present in the images, such as radius, texture, perimeter, area, smoothness, compactness, concavity, concave points, symmetry, and fractal dimension.
The neural network model, implemented using Keras, consists of multiple hidden layers with ReLU activation functions, a dropout layer to prevent overfitting, and an output layer for binary classification (benign or malignant). It's trained using back-propagation and optimized with stochastic gradient descent.
To use the model, you can find the code in the provided Jupyter notebook file. The project requires Python libraries like Keras, TensorFlow, Pandas, NumPy, and Scikit-learn. The dataset used was created by Dr. William H. Wolberg at the University of Wisconsin, Clinical Sciences Center in Madison, WI, USA.
Overall, this project aims to develop a neural network-based breast cancer detection system using a dataset of image-derived features.
