Dr Caroline Clark - A beginner's guide to data analysis in cosmology using Jupyter Notebook
 
31:56
Filmed at PyData London 2017 Description Current cosmology experiments face exciting computational challenges in statistics and machine learning, with large amounts of data to process. In this beginner's session, we will use Jupyter Notebook to visualise and analyse real cosmological data, using easy to implement code examples from well known python packages such as AstroML, scipy, healpy, numpy, pymc, scikit-learn and matplotlib. Abstract As cosmology has entered the era of precision measurement, academics face the exciting challenges of analysing large datasets, many of these common to other areas of Big Data. In recent years Python has evolved as a standard tool in astronomy and cosmology due to the availability of open source statistical analysis and machine learning packages that allow the development of robust data analysis pipelines and powerful visualisations. In this session, I’d like to demonstrate how a beginner to the field of cosmology can use open data along with the Jupyter Notebook to visualise and analyse real cosmological data, using easy to implement code examples from well known python packages such as AstroML, scipy, healpy, numpy, pymc, scikit-learn and matplotlib. www.pydata.org PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R. We aim to be an accessible, community-driven conference, with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases.

Authors: Vanderplas, Jake, University of Washington; Ivezic, Zeljko, University of Washington; Connolly, Andrew, University of Washington Track: General As astronomical data sets grow in size and complexity, automated machine learning and data mining methods are becoming an increasingly fundamental component of research in the field. The astroML project (http://astroML.github.com), first released in fall 2012, provides a common repository for practical examples of the data mining and machine learning tools used and developed by astronomical researchers, written in python. The astroML module offers a host of general data analysis and machine learning routines, loaders for openly-available astronomical datasets, and fast implementations of specific computational methods often used in astronomy and astrophysics. The associated website features hundreds of examples of these routines in action, using real datasets. In this talk I'll go over some of the highlights of the astroML code and examples, and discuss how we've used astroML as an aid for student research, hands-on graduate astronomy curriculum, and the sharing of research tools and results.

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Astroinformatics is an interdisciplinary field of study involving the combination of astronomy, data science, informatics, and information/communications technologies. Astroinformatics is primarily focused on developing the tools, methods, and applications of computational science, data science, and statistics for research and education in data-oriented astronomy. Early efforts in this direction included data discovery, metadata standards development, data modeling, astronomical data dictionary development, data access, information retrieval, data integration, and data mining in the astronomical Virtual Observatory initiatives. Further development of the field, along with astronomy community endorsement, was presented to the National Research Council (United States) in 2009 in the Astroinformatics "State of the Profession" Position Paper for the 2010 Astronomy and Astrophysics Decadal Survey. That position paper provided the basis for the subsequent more detailed exposition of the field in the Informatics Journal paper Astroinformatics: Data-Oriented Astronomy Research and Education. Astroinformatics as a distinct field of research was inspired by work in the fields of Bioinformatics and Geoinformatics, and through the eScience work of Jim Gray (computer scientist) at Microsoft Research, whose legacy was remembered and continued through the Jim Gray eScience Awards. Though the primary focus of Astroinformatics is on the large worldwide distributed collection of digital astronomical databases, image archives, and research tools, the field recognizes the importance of legacy data sets as well—using modern technologies to preserve and analyze historical astronomical observations. Some Astroinformatics practitioners help to digitize historical and recent astronomical observations and images in a large database for efficient retrieval through web-based interfaces. Another aim is to help develop new methods and software for astronomers, as well as to help facilitate the process and analysis of the rapidly growing amount of data in the field of astronomy. Astroinformatics is described as the Fourth Paradigm of astronomical research. There are many research areas involved with astroinformatics, such as data mining, machine learning, statistics, visualization, scientific data management, and semantic science. Data mining and machine learning play significant roles in Astroinformatics as a scientific research discipline due to their focus on "knowledge discovery from data" (KDD) and "learning from data". The amount of data collected from astronomical sky surveys has grown from gigabytes to terabytes throughout the past decade and is predicted to grow in the next decade into hundreds of petabytes with the Large Synoptic Survey Telescope and into the exabytes with the Square Kilometre Array. This plethora of new data both enables and challenges effective astronomical research. Therefore, new approaches are required. In part, due to this data-driven science is becoming a recognized academic discipline. Consequently, astronomy (and other scientific disciplines) are developing sub-disciplines information and data intensive to an extent that these sub-disciplines are now becoming (or have already become) stand alone research disciplines and full-fledged academic programs. While many institutes of education do not boast an astroinformatics program, the most likely will in the near future. Informatics has been recently defined as "the use of digital data, information, and related services for research and knowledge generation". However the usual, or commonly used definition is "informatics is the discipline of organizing, accessing, integrating, and mining data from multiple sources for discovery and decision support."....

YOW! Data 2016 Natalia Rümmele - Automating Data Integration with Machine Learning #YOWData
 
22:43
The world of data is a messy and unstructured place, making it difficult to gain value from data. Things get worse when the data resides in different sources or systems. Before we can perform any analytics in such a case, we need to combine the sources and build a unified view of the data. To handle this situation, a data scientist would typically go through each data source, identify which data is of interest, and define transformations and mappings which unify these data with other sources. This process usually includes writing lots of scripts with potentially overlapping code – a real headache in the everyday life of a data scientist! In this talk we will discuss how machine learning techniques and semantic modelling can be applied to automate the data integration process. Natalia is a data scientist in the data platforms group at Data61, CSIRO. She is passionate about social network analysis, web mining and machine learning with specialization on data mining and link prediction. Her experience includes working on data intensive projects in Ukraine, Austria, Japan and Australia. For more on YOW! Data, visit http://data.yowconference.com.au

Machine learning with Python and sklearn - Hierarchical Clustering (E-commerce dataset example)
 
09:06
In this Machine Learning & Python video tutorial I demonstrate Hierarchical Clustering method. Hierarchical Clustering is a part of Machine Learning and belongs to Clustering family: - Connectivity-based clustering (hierarchical clustering) - Centroid-based clustering (K-Means Clustering) - https://www.youtube.com/watch?v=iybATqk6LNI - Distribution-based clustering - Density-based clustering In data mining and statistics, Hierarchical Clustering also called hierarchical cluster analysis or HCA is a method of cluster analysis which seeks to build a hierarchy of clusters. In this video I demonstrate how Agglomerative Hierarchical Clustering is working. Must know for Hierarchical Clustering is knowing Dendrograms. Dendrogram helps you to decide the optimal number of clusters for your dataset. For executing task in Python I used: - sklearn library that is for Machine Learning algorithms. - ward method that means Minimum Variance Method. If you are interesting more in Hierarchical Clustering, read my article on LinkedIn where I described my experiment about combining Machine Learning (Hierarchical Clustering) in GIS (Geographical Information System). - https://www.linkedin.com/pulse/machine-learning-gis-hierarchical-clustering-urban-bielinskas Data-set for this example is taken from https://www.kaggle.com. There you can find many dataset for very different Machine Learning tasks. Hierarchicaal Clustering is very usable in solving Data Analysis, Data Mining and Statistics problems.

Risa Wechsler: Cosmologists use data science to explain the origins of the universe
 
18:36
A new generation of powerful telescopes will generate vast amounts of data, but crunching those numbers poses difficult challenges for data scientists. Cosmology, the study of the origin of the universe, is usually thought of as the realm of astronomers armed with giant telescopes and sophisticated satellites. But it is also a data science, “and a very interesting one,” says Risa Wechsler, an associate professor of physics at Stanford University. Explaining that relationship was the theme of Wechsler’s talk at this year’s Women in Data Science conference at Stanford. “I have the pleasure to talk to you about trying to understand the data of literally the entire universe. So that’s definitely a big data problem.” Cosmology, she says, is striving to answer fundamental questions about the universe, such as how did it begin, what is it made of, what’s accelerating it, and how did galaxies form? The links between cosmology and data science are especially pertinent now as researchers prepare to analyze a flood of data from two new and extremely powerful telescopes – the Large Synoptic Survey Telescope, or LSST, and the Hyper Suprime-Cam Telescope. When completed, the LSST will contain a 3200-megapixel camera, the largest ever built. Cosmology, Wechsler says, has undergone a revolution in the last 20 years, driven by the vast increase in data available to analyze. The LSST, for example, will take a picture of the entire sky every three days, producing about 20 terabytes of data a night. Simulations of the universe have grown exponentially over the years. Wechsler demonstrated that by showing a simulation made in 1985, which contained 32,000 particles. A similar simulation performed in 2014 contained a trillion particles. Building it took several tens of millions of CPU hours on one of the largest computers in the world, according to Wechsler. Building the models involves combining data from parts of the visible universe with data derived using machine learning and other types of statistical inference. Doing so allows scientists to make predictions about what the universe as a whole looks like and how to infer the parameters that determine how it behaves. Dealing with such a massive amount of data poses challenges. Often the available computational resources aren’t sufficient, “so we have to be smart about picking which pieces of that problem we solve and in what combination,” Wechsler says. Accuracy is important to all researchers, of course, but Wechsler says she and her colleagues feel a special responsibility to be careful. “We’re really trying to tell you what is the physics of the universe, and we don’t want to get it wrong.”
