Stock-Market-Sentiment-Analysis

Identification of trends in the stock prices of a company by performing fundamental analysis of the company. News articles were provided as training data-sets to the model which classified the articles as positive or neutral. Sentiment score was computed by calculating the difference between positive and negative words present in the news article. Comparisons were made between the actual stock prices and the sentiment scores. Naive Bayes, OneR and Random Forest algorithms were used to observe the results of the model using Weka

Foursquare-clone

Oingo is a new mobile app named that allows users to share useful information via their mobile devices based on social, geographic, temporal, and keyword constraints. The main idea in oingo is that users can publish information in the form of short notes, and then link these notes to certain locations and certain times. Other users can then receive these notes based on their own location, the current time, and based on what type of messages they want to receive

Reinforcement-Learning-Comparative-Study

Comparative study of Reinforcement Learning Algorithms on Ping Pong game: In the current design of experience replay we sample uniformly to obtain the minibatch and update the model. Devising a way to sample more experience points close to the tricky areas would help solving this problem, better the training rate and improve convergence. We designed a game environment for the Android platform as few such environments are available at the moment. Moreover, during the pre-processing game we removed the background and score to reduce clutter and increase likeliness of successful training. It would be interesting to see how restoring the background affects agent’s performance. Overall, our results show the capacity of Deep neural networks and how a generic reinforcement learning setup such as this could learn and play the game with very minimal domain knowledge.

SF-Opioid-Crisis

San Francisco (SF) has a long history of pushing the envelope on progressive public health solutions, including medical cannabis and needle exchange, before either was legal or broadly embraced. It is so out of proportion, that California passed a bill allowing SF to open Safe Injection Sites (SIS).

Fashion-MNIST

Fashion-MNIST is a dataset of Zalando's article images—consisting of a training set of 60,000 examples and a test set of 10,000 examples. Each example is a 28x28 grayscale image, associated with a label from 10 classes. Zalando intends Fashion-MNIST to serve as a direct drop-in replacement for the original MNIST dataset for benchmarking machine learning algorithms. It shares the same image size and structure of training and testing splits.
