aaivu-pump-and-dump-detection-crypto-currencies
Inspired by the immense success shown by artificial neural networks in computer vision on images classification, we propose a novel framework to detect one of the rife fraudulent financial manipulations in crypto currency trading world known as pump and dump. The representation of crypto currency financial charts was re-imagined to ameliorate the classification by taking advantage of some of the very recent advancements of time series to spatial encoding techniques of Gramian Angular Field (GAF), Markov Transition Field (MTF) and Recurrence plots (RP) that are capable of spatially encoding the temporal financial time series data in the form of images. Encoded images were then used to train several convolutional neural network architectures which have been able to achieve a very high precision, recall and F1 values close to 99% over the unseen data for the above classification task. This is one of the first of such researches in pump and dump detection in crypto currencies using computer vision. This approach has the potential to be extended in detecting predefined shapes of time series charts.

aaivu/aaivu-semantic-table-interpretation
Semantic Table Interpretation is the use of external knowledge bases or ontologies to provide context to tabular data sources. Data usually loses its context when converted into tabular structures. Hence, mapping these data back into its original context is non trivial. Since table data is one of most widespread structures in use, the information loss is significant. In this project, we introduce a two novel algorithms, ReleX and STEM, to derive meaning full relationships between table columns and to identify table entities with context using web ontologies.

aaivu/aaivu-emotion-analysis-for-conversational-texts
This is a Deep Learning based approach to classify the emotion of a textual utterance given its two previous turns of context. Happy, Sad and Angry are the main emotion classes to be considered. The main objective of the project is to propose an effective and efficient model to analyze the emotions in conversational texts. The solution contains 3 main components such as pre-processing, word embedding and classification.
aaivu/aaivu-information-extraction-from-receipts
Retail stores play a vital role in the supply chain of the business process and act as a bridge between the customers and manufacturers of the products. For a particular supermarket, receipts share some common elements such as shop name, shop address but they vary in product details. Along with that supermarkets maintain a unique template for their receipts so finding a common template for cross supermarket receipts is not a viable effort. Hence our project is to develop an Automated Information Extraction System to identify information from printed grocery receipts and deliver the information as the interoperable format.
