Abstractive Text Summarization
The project was to do Extravtive and Abstrative Text Summarization for articles. The Abstractive Text Summarization was based on Page Rank algorithm and Eucledian Distance/Cosine Similarity
The Abstractive Text Summarization was bsed on Encoder Decoder Architecture and was developed on Tensorflow. The project required NLP Pre Processing tasks(Noise Removal, Text Cleaning, Contraction Removal, HTML Tags removal etc). The tex was tokenised into sentences and then into words using Keras and NLTK. The application was built with word embeddings and attention layers
Below was a sample output from the application:

The project was to build a Knowledge Graph from a set of PDF documents and extraxt information from the Knowledge Graph. The project was based on Natural Language Processing concepts and required to process the documents, extract the entity pairs(NER) and their relationships and build the knowledge graph.
Further, exract the graph for an entity, a relationship and build a question answer application.

Neural Style Transfer
The project was to build a Neural Style Transfer application. The source was two separate images and the application extracts feature vectore from the first image and style vector from second image and builds and image merging the two.
The project was based on CNN architectureShow More Show Less
Demand Forecasting for a Food Delivery customer
The Machine Learning application was built for a Food Delivery customer to predict demand for orders for next 3 months on a weekly basis. Historical data for previous 145 weeks was provided.
The project POC was developed with following activities:
1. Data Cleansing
2. Descripive & Inferential Statistics
3. Null Value Treatment
4. Data Visualization
5. Feature Engineering
6. Test of Seasonality and Stationarity
7. Data Normalization
8. Dimentionality Reduction
The model was build on multiple algorithms: Light GBM, Catboost, XG Boost and ARIMA. Finally, the predicted values from the 4 algorithms were stacked to get the final outputShow More Show Less
