PyData 2015 Keynote: "A Systems View of Machine Learning" Joshua Bloom
Despite the growing abundance of powerful tools, building and deploying machine-learning frameworks into production continues to be major challenge, in both science and industry. I'll present some particular pain points and cautions for practitioners as well as recent work addressing some of the nagging issues. I advocate for a systems view, which, when expanded beyond the algorithms and codes to the organizational ecosystem, places some interesting constraints on the teams tasked with development and stewardship of ML products.
About: Dr. Joshua Bloom is an astronomy professor at the University of California, Berkeley where he teaches high-energy astrophysics and Python for data scientists. He has published over 250 refereed articles largely on time-domain transients events and telescope/insight automation. His book on gamma-ray bursts, a technical introduction for physical scientists, was published recently by Princeton University Press. He is also co-founder and CTO of wise.io, a startup based in Berkeley. Josh has been awarded the Pierce Prize from the American Astronomical Society; he is also a former Sloan Fellow, Junior Fellow at the Harvard Society, and Hertz Foundation Fellow. He holds a PhD from Caltech and degrees from Harvard and Cambridge University.
All developers understand the theoretical value of unit testing, but with data driven applications, figuring out how to create tests can be hard. In this session, you will learn how to design and build a data layer that can be tested. We will introduce data layer architecture practices and methodologies that make testing possible, and cover the basics of unit test mocking. You will also be guided through various types of testing, including unit, integration, and functional testing. Leave this session with the basics needed to start creating tests for application data layers, including those powered by LinqToSQL and Entity Framework.

A quick, off-the-cuff talk about why I think SQL is good for scientists. Please send me notes correcting my Python, arguing, or asking for more information! And see the tutorial at: http://uwescience.github.io/sqlshare
Agile Data Science 2.0 covers the theory and practice of applying agile methods to the practice of applied analytics research called data science. The book takes the stance that data products are the preferred output format for data science teams to effect change in an organization. Accordingly, we show how to "get meta" to enable agility in building applications describing the applied research process itself. Then we show how to use 'big data' tools to iteratively build, deploy and refine analytics applications. Tracking data-product development through the five stages of the "data value pyramid", we show you how to build applications from conception through development through deployment and then through iterative improvement. Application development is a fundamental skill for a data scientist, and by publishing your data science work as a web application, we show you how to effect maximal change within your organization.
Technologies covered include Python, Apache Spark (Spark MLlib, Spark Streaming), Apache Kafka, MongoDB, ElasticSearch and Apache Airflow.
Agile Data Science 2.0 (O’Reilly 2017) defines a methodology and a software stack with which to apply the methods. The methodology seeks to deliver data products in short sprints by going meta and putting the focus on the applied research process itself. The stack is but an example of one meeting the requirements that it be utterly scalable and utterly efficient in use by application developers as well as data engineers. It includes everything needed to build a full-blown predictive system: Apache Spark, Apache Kafka, Apache Incubating Airflow, MongoDB, ElasticSearch, Apache Parquet, Python/Flask, JQuery. This talk will cover the full lifecycle of large data application development and will show how to use lessons from agile software engineering to apply data science using this full-stack to build better analytics applications.

Whether you're running into problems or just want to optimize your performance, these skills will be useful.
Agile Data Science 2.0 (O'Reilly 2017) defines a methodology and a software stack with which to apply the methods. *The methodology* seeks to deliver data products in short sprints by going meta and putting the focus on the applied research process itself. *The stack* is but an example of one meeting the requirements that it be utterly scalable and utterly efficient in use by application developers as well as data engineers. It includes everything needed to build a full-blown predictive system: Apache Spark, Apache Kafka, Apache Incubating Airflow, MongoDB, ElasticSearch, Apache Parquet, Python/Flask, JQuery.

The entire lifecycle of big data application development is discussed. The system starts with plumbing, moving on to data tables, charts and search, through interactive reports, and building towards predictions in both batch and realtime (and defining the role for both), the deployment of predictive systems and how to iteratively improve predictions that prove valuable.
Data Exploration with Apache Drill: Day 1Charles Givre
Study after study shows that data scientists and analysts spend between 50% and 90% of their time preparing their data for analysis. Using Drill, you can dramatically reduce the time it takes to go from raw data to insight. This course will show you how.

Open Source 101 2022 - MySQL Indexes and HistogramsFrederic Descamps
Nobody complains that the database is too fast. But when things slow down, the complaints come quickly. The two most popular approaches to speeding up queries are indexes and histograms. But there are so many options and types on indexes that it can get confusing. Histograms are fairly new to MySQL but they do not work for all types of data. This talk covers how indexes and histograms work and show you how to test just how effective they are so you can measure the performance of your queries.
Prepares the students for (and is a prerequisite for) the more advanced material students will encounter in later courses. Data structures organize data Þ more efficient programs.

“Create” is the correct Answer
DDL or Data Definition Language actually consists of the SQL commands that can be used to define the
database schema. It simply deals with descriptions of the database schema and is used to create and
modify the structure of database objects in the database.
Examples of DDL commands:
CREATE – is used to create the database or its objects (like table, index, function, views, store procedure
and triggers).
DROP – is used to delete objects from the database.
ALTER-is used to alter the structure of the database.
4. TRUNCATE–is used to remove all records from a table, including all spaces allocated for the records are
removed.
COMMENT –is used to add comments to the data dictionary.
RENAME –is used to rename an object existing in the database.
The SQL commands that deals with the manipulation of data present in the database belong to DML or
Data Manipulation Language and this includes most of the SQL statements.
Examples of DML:
INSERT – is used to insert data into a table.
UPDATE – is used to update existing data within a table.
DELETE – is used to delete records from a database table.

need to develop the strategy for the ongoing sales for the previous months , current and the future
month considering in mind that you have the sales data of past 5 year. You need to use Azure Data
Services which of the following Analytics services will you use to determine the correct answer and
make strategy accordingly.
1. To answer the question: What’s happening in the sales part with the Data ?
2. To answer the question: Why’s happening that for certain months the sales increased ?
3. To answer the question: What will happen at the sales front in the coming 2 years ?
4. To answer the question: What actions should we take so that sales will increase?
What will be the correct service you use for (1) ?
A. Prescriptive
B. Predictive
C. Diagnostic
D. Descriptive
E. Cognitive Analytics
Answer: D
Explanation:
Descriptive, to answer the question: What’s happening?
Diagnostic, to answer the question: Why’s happening?
Predictive, to answer the question: What will happen?
8. Prescriptive, to answer the question: What actions should we take?
Descriptive
What’s happening?
Monitor the status of machines, devices, products, and assets.
Assess if things are going according to plan, or to alert people if anomalies arise.
What’s the throughput and utilization of this machine?
Are there any anomalies that require immediate attention?
How much energy is this machine consuming?
How many parts are we producing with this tool?
How are customers using our products?
Where are my assets?
Diagnostic
Why is something happening?
Examine data from multiple angles to understand why something is happening.
The goal is to find the root cause of a problem, in order to fix, or improve something (a process, a
service, or a product).
Why is the OEE of this machine so low?
Why is this machine producing more defective parts than the others?
Why is this machine consuming so much energy?
Why are we producing so few parts with this tool?
Why are we getting so many returns of this product?
Why are we getting so many product returns from our European customers?
Predictive
What will happen?
Calculate the probability that something will happen within a specific timeframe, based on historical
data.
The goal is to proactively take some sort of corrective action before something (usually bad) happens,
mitigate risk, or to identify opportunities to gain a competitive advantage.
What’s the probability of this machine failing in the next 24 hours?
What is the expected remaining useful life of this tool?
9. When should I plan service for this machine?
What will be the demand for this product or feature?
Prescriptive
What actions should I take?
Recommend actions as a result of a diagnosis or a prediction, or at least provide some visibility to the
reasoning behind a diagnostic or prediction.
Often the recommendations are about how to fix or optimize something.
This machine is 90 percent likely to fail in the next 24 hours. What should I do to prevent it?
The OEE of this machine is low. What can I do to improve it?
This machine is producing too many defective parts. What should I do to avoid this?
This design is causing many manufacturing issues. How can I improve the design to reduce them?
