Practical Data Science Examples: Santa Ana Detection and Demographics Analysis from Satellite Images
Two research projects will be presented to demonstrate the application of data science techniques to real-world problems. In one use case, cluster analysis is applied to sensor measurements from weather stations to provide location-specific and time-specific detection of Santa Ana conditions. The Kepler workflow system and Spark distributed framework are used to add usability and scalability. In another use case, satellite images are processed to analyze the demographics distribution of a region. This approach uses deep learning as well as conventional machine learning techniques to analyze satellite imagery, and has applications to several remote sensing problems.

Analyzing Big Data Using Workflows: From Fighting Wildfires to Helping Patients
We will be looking at the scope of Data Science as a field, Big Data and Big Compute as disciplines, their respective trends and the new era of Data Science. This new era of Data Science encompasses new and unique challenges involving many factors like volume, velocity, and variety- and also new tools to combat these challenges. From people, purpose, process, platforms, and programmability - we will take a look at how to navigate Big Data as a discipline and process utilizing workflows, as well as looking at various applications of using workflows to analyze big data such as the WIFIRE project.
Wildfires are critical for ecosystems in many geographical regions. However, our current urbanized existence in these environments is inducing the ecological balance to evolve into a different dynamic leading to the biggest fires in history. Wildfire wind speeds and directions change in an instant, and first responders can only be effective if they take action as quickly as the conditions change. What is lacking in disaster management today is a system integration of real-time sensor networks, satellite imagery, near-real time data management tools, wildfire simulation tools, and connectivity to emergency command centers before, during and after a wildfire. As a first time example of such an integrated system, the WIFIRE project is building an end-to-end cyberinfrastructure for real-time and data-driven simulation, prediction and visualization of wildfire behavior. This paper summarizes the approach and early results of the WIFIRE project to integrate networked observations, e.g., heterogeneous satellite data and real-time remote sensor data with computational techniques in signal processing, visualization, modeling and data assimilation to provide a scalable, technological, and educational solution to monitor weather patterns to predict a wildfire’s Rate of Spread.

John Hildebrand / Scripps Oceanography.
Recent advances in digital data storage capacity and low power electronics have made it possible to collect long-term continuous broadband passive acoustic data and thereby capture the full range of marine mammal sound production in an ocean setting.
Advances are also required in data curation, search, analysis, and visualization. We have developed methods to analyze and manage passive acoustic monitoring data that we are now acquiring at a rate of approximately 25 Tb/month.
Initial stages of data processing include converting the data from the internal instrument format to a standard audio file format with metadata extensions and preparation of both working and archival copies of the data. Standardized spectra are calculated for all data using a minimum of three frequency bands: (1) high frequency up to 160 kHz, (2) mid frequency up to 5 kHz, and (3) low frequency up to 1 kHz.
A set of 16 CPUs are operated in parallel for timely initial data processing. A number of automatic detectors are run on the data including: spectrogram correlation for blue whale call detection, energy detection for fin whale calls and anthropogenic sounds, power-law detector for humpback whale units, and Teager-energy based echolocation click detection and an expert system for beaked whale echolocation clicks.
Software (Triton) has been developed for efficient manual scanning and signal discovery. The key feature of Triton is the capability to display spectrograms on virtually any time scale and provide an index between long-term spectral averages (minutes to days) and short-term spectrograms (sec to msecs). Analysis effort is also standardized using a detection logger feature, allowing multiple analysts to contribute to the same dataset with uniform coverage. Detections are aggregated into a database (Tethys) that allows combination of multiple datasets and association with environmental or other data.
Javier R. Movellan / UC San Diego and Emotient
The human brain could be described as a computer designed to operate with hands and faces. The hands and the face take about 80% of the sensory motor areas of the human brain. The hands specialize in interaction with the physical world and the face in interaction with the social world. Computers can do complex things with the information we provide them with our hands via keyboard and mouse, but until recently they have been blind to the wealth of information we provide with our faces. For the last 20 years the Machine Perception Laboratory at UCSD has been pursuing the development of technology for automatic recognition of facial expressions. In this talk I will present the progress we made, from the early proof of concept prototypes, to the development of the first commercial smile detector embedded in digital cameras, to the implementation of large scale real time expression recognition systems.
