Data Science wikipedia A practitioner of data science is called a data scientist. Data scientists solve complex data problems through employing deep expertise in some scientific discipline. It is generally expected that data scientists are able to work with various elements

Data Science wikipedia Good data scientists are able to apply their skills to achieve a broad spectrum of end results. the ability to find and interpret rich data sources, manage large amounts of data despite hardware, software and bandwidth constraints, merge data sources together, ensure consistency of data-sets, create visualizations to aid in understanding data, build mathematical models using the data, present and communicate the data insights/findings to specialists and scientists in their team and if required to a naive audience.

Data Science in WINE Once viewed as a luxury good, nowadays wine is increasingly enjoyed by a wider range of consumers. Wine certification is generally assessed by physicochemical and sensory tests

sensory tests Example: Chateau Latour Latour-2010/wine/110508/detail.aspx

sensory tests Among those expert reviews, we use “Wine Spectator’s” version "Unbelievably pure, with distilled cassis and plum fruit that cuts a very precise path, while embers of anise, violet and black cherry configure form a gorgeous backdrop. A bedrock of graphite structure should help this outlive other 2010s. Powerful, sleek and incredibly long. Not perfect, but very close. Best from 2020 through 2050." 99 Points Wine Spectator

sensory tests Wine Spectator has the following advantages: Words are precise Well-known Famous for it’s Top 100 wine of the year selection Well maintained database

Research Topic 1 Clustering on past 10 years Top 100 wine (1000 wines) Challenges: Extract attributes from 1000 wine Clustering algorithm Analysis of the results

Research Topic 2 Multi-label (4 classes) Classification on 1000 wines, which composed of 250 wines for 4 category (95+, 90~94, 89~85, 85-) Challenges: Classification algorithm 4 classes How to improve accuracy

Research Topic 3 Association Rules on region-specific dataset (such as Napa) for attribute correlation and quality prediction. Challenges: Association Rules algorithm Analysis of the results How to improve accuracy

Research Topic 4 Region Prediction (such as France vs Italy), open for association rules or classification algorithms. Challenges: More free-style (more suitable for experienced researchers) Not only focus on accuracy, but also try to tell the difference between the regions

Research Topic 5 Clustering + Classification for higher accuracy prediction. Challenges: TWO type of algorithms More complex in understanding and coding

Research Topic 6 Multi-label research: since we have multiple reviews available, how to use those information for data science research? Challenges: Very flexible!!!
