This is just meant as a fun and quick technical challenge. But if you are one of the remaining 1+ million users, maybe you should switch to something else :)

creditcardfrauddetection_finalproject icon creditcardfrauddetection_finalproject

Kaggle Competiton: Using Anomaly detection technique on a highly imbalanced high dimensional data to detect fraud. Used variety of technique including SMOTE to balance the data set and other machine learning technique to build the model.

handson-ml icon handson-ml

A series of Jupyter notebooks that walk you through the fundamentals of Machine Learning and Deep Learning in python using Scikit-Learn and TensorFlow.

handson-ml2 icon handson-ml2

A series of Jupyter notebooks that walk you through the fundamentals of Machine Learning and Deep Learning in Python using Scikit-Learn, Keras and TensorFlow 2.

im2txt_word2vec icon im2txt_word2vec

Image Captioning using word2Vec technique involving Deep learning techniques like CNN and RNN (LSTM).

mmm_stan icon mmm_stan

Python/STAN Implementation of Multiplicative Marketing Mix Model, with deep dive into Adstock (carry-over effect), ROAS, and mROAS

objectclassification_cnn_keras icon objectclassification_cnn_keras

Using CNN with Keras and Tensorflow, we have a deployed a solution which can train any image on the fly. Code uses Google Api to fetch new images, VGG16 model to train the model and is deployed using Python Django framework

restricted-boltzman-machine-rbm- icon restricted-boltzman-machine-rbm-

Using RBM to work on Classifying MNSIT handwritten data-set for classification. RBM is implemented from scratch and not using any libraries. This helps understanding the maths and how an energy function and its probability distribution is used in an Machine Learning domain

robyn icon robyn

Robyn is an experimental, automated and open-sourced Marketing Mix Modeling (MMM) code from Facebook Marketing Science. It uses various machine learning techniques (Ridge regression with cross validation, multi-objective evolutionary algorithm for hyperparameter optimisation, gradient-based optimisation for budget allocation etc.) to define media channel efficiency and effectivity, explore adstock rates and saturation curves. It's built for granular datasets with many independent variables and therefore especially suitable for digital and direct response advertisers with rich dataset.
