• Abstract: Machine learning has typically focused on developing models and algorithms that would ultimately replace humans at tasks where intelligence is required. In this work, rather than replacing humans, we focus on unveiling the potential of machine learning to improve how people learn and remember factual material. To this end, we perform a large-scale randomized controlled trial with thousands of learners from a popular learning app in the area of mobility. After controlling for the length and frequency of study, we find that learners whose study sessions are optimized using machine learning remember the content over $\sim$67% longer than those whose study sessions are generated using two alternative heuristics. Our randomized controlled trial also reveals that the learners whose study sessions are optimized using machine learning are $\sim$50% more likely to return to the app within 4-7 days.

  We propose spire, a system that decomposes tasks into smaller learning subproblems and second combines imitation and reinforcement learning to maximize their strengths. We find that spire outperforms prior approaches that integrate imitation learning, reinforcement learning, and planning by 35% to 50% in average task performance.

  Reinforcement learning (RL) algorithms hold the promise of enabling autonomous skill acquisition for robotic systems.

In this work, we study how these challenges can be tackled by effective utilization of diverse offline datasets collected from previously seen tasks.

  Human Activity Recognition (HAR) describes the machines ability to recognize human actions. Challenge in HAR is to overcome the difficulties of separating human activities based on the given data. Deep Learning techniques like Long Short-Term Memory (LSTM), Bi-Directional LS classifier, Recurrent Neural Network (RNN), and Gated Recurrent Unit (GRU) are trained. Experiment results proved that the Linear Support Vector in machine learning and Gated Recurrent Unit in Deep Learning provided better accuracy for human activity recognition.
