Aptly: Making Mobile Apps from Natural Language

This paper introduces Aptly, a platform designed to democratize mobile app development, particularly for young learners. Aptly integrates a Large Language Model (LLM) with App Inventor, enabling users to create apps using their natural language. User's description is translated into a programming language that corresponds with App Inventor's visual blocks. A preliminary study with high school students demonstrated the usability and potential of the platform. Prior programming experience influenced how users interact with Aptly. Participants identified areas for improvement and expressed a shift in perspective regarding programming accessibility and AI's role in creative endeavors.

A Statistical Analysis of Recent Traffic Crashes in Massachusetts

A statistical analysis implemented in the Python programming language was performed on the available MassDOT car accident data to identify whether a certain set of traffic circumstances would increase the likelihood of injuries. In the analysis, we created a binary classifier as a model to separate crashes that resulted in injury from those that did not. To accomplish this, we first cleaned up the initial data, then proceeded to represent categorical variables numerically through one hot encoding before finally producing models with Recursive Feature Elimination (RFE) and without RFE, in conjunction with logistic regression. This statistical analysis plays a significant role in our modern road network that has presented us with a heap of obstacles, one of the most critical being the issue of how we can ensure the safety of all drivers and passengers. Findings from our analysis identify that tough weather and road conditions, senior/teen drivers and dangerous intersections play prominent roles in accidents that resulted in injuries in Massachusetts. These new findings can provide valuable references and scientific data support to relevant authorities and policy makers for upgrading road infrastructure, passing regulations, etc.
