Python Tutorial: Reindexing DataFrames
 
04:36
Second video of the first chapter of our course: Merging DataFrames with pandas by Dhavide Aruliah. First chapter free: https://www.datacamp.com/courses/merging-dataframes-with-pandas As a Data Scientist, you'll often find that the data you need is not in a single file. It may be spread across a number of text files, spreadsheets, or databases. You want to be able to import the data of interest as a collection of DataFrames and figure out how to combine them to answer your central questions. This course is all about the act of combining, or merging, DataFrames, an essential part of any working Data Scientist's toolbox. You'll hone your pandas skills by learning how to organize, reshape, and aggregate multiple data sets to answer your specific questions. Now we can import many files into individual DataFrames, let's investigate sharing information between DataFrames using their Indexes. This is essential for combining DataFrames later, as Indexes are the means by which DataFrame rows are labelled. Let's make a brief note on terminology. The plural of "index" in English can be indexes or indices; both are acceptable. Let's adopt the convention of using indices as the plural of index when referring to individual labels within an Index data structure. By contrast, we can use indexes as the plural of index with reference to many Index data structures associated with several Pandas Series or DataFrames. This is not a standard convention, but it helps us resolve ambiguity in thinking about, say, sets of indices within many indexes. To start, let's load two DataFrames of temperature data recorded from Pittsburgh in 2013. For both calls to read_csv(), we use the index_col argument to specify which column becomes the DataFrame Index ('Month' in both cases). Remember, the Index is a privileged column in Pandas providing convenient access to Series or DataFrame rows. We can examine our DataFrames w_mean & w_max more closely. The Mean TemperatureF & Max TemperatureF columns are respectively the average & maximum daily temperatures (in Fahrenheit) observed during three-month intervals or quarters. For both DataFrames, the column Month is the DataFrame Index. The month listed in each Index row is the first month of each quarter. By virtue of how the CSV files are stored, the Index of w_mean is in alphabetical order while the Index of w_max is in chronological order; the former gives a distorted sense of time-dependent trends. The DataFrame Indexes are accessed directly with the .index attribute. Both w_mean & w_max have Indexes of type object because the index labels are strings. The Pandas type() function shows us the data type of the Index. We define a list called ordered to impose a deliberate ordering for the Index labels of w_mean. The DataFrame .reindex() method creates a new DataFrame w_mean2 with the same data as w_mean but with a new row ordering according to the input list ordered. We can see that w_mean2 has the desired chronological ordering. The original alphabetically-ordered DataFrame can be recovered with the DataFrame .sort_index() method. Pandas Index labels are typically sortable data, such as numbers, strings, or datetimes. The input argument to the .reindex() method can also be another DataFrame Index. For instance, here, we use the Index from w_max to reindex w_mean in chronological order. When a suitably indexed DataFrame is available, the reindex() method spares us having to create a list manually or having to sort the Index. The specific Index labels provided to the .reindex() method are important. For instance, if we invoke .reindex() again using an input list containing a label that is not in the original DataFrame Index (Dec in this case), an entirely new row is inserted & filled with the null value NaN or not-a-number. We can also use .reindex() to see where DataFrame rows overlap. For instance, here, we reindex w_max with the index of w_mean3 showing that w_max does not have a row labelled Dec either. Using .dropna() removes entire rows in which null values occur. This is a common first step when merging DataFrames. Finally, we should realize that order counts. That is, w_max.reindex(w_mean.index) is not the same as w_mean.reindex(w_max.index). The latter fixes the row order as desired in w_mean; the former replicates the misleading alphabetical row order in w_max; this is likely not desired. Try reindexing some DataFrames now in the exercises.

Explore the simple fundamentals of indices and how to place trades in 90 seconds. The video transcript: What are Indices? Today, we’re going to explain a little about what Indices are and how they work from a trading perspective. The word “Indices” is the plural form of Index. Stock market indices measure the value of a selection of companies in the stock market. They can let investors see how a particular set of assets – based in a specific industry sector or a certain part of the world – is performing. There are lots of different types of indices, which each use different formulas to calculate the index price. Market value-weighted indices are the most common type; here, the bigger the company’s average return, the greater the influence it’ll have on the price of the index as a whole. Price-weighted indices are based on the company’s share price. Companies with high share prices have a larger amount of influence on price-weighted indices. There’s a lot more to learn about Indices.

Market Index Explained: Guide to Security Market Indices

Market Index Explained: Guide to Security Market Indices FINANCE & FINANCIAL MARKETS 1. What is an Index? 1:49 2. What Do We Use Indices For? 3:38 3a). Different Types of Indices: Price vs Total Return 4:47 3b). Different Types of Indices: Weights 5:54 3c). Different Types of Indices: Underlying Securities 10:48 4. Rebalancing and Reconstitution 13:35 1.WHAT IS AN INDEX? It’s a numerical Value ...generated, published and promoted by a private organisation This value is calculated from Market Prices of the index's Constituents Constituents are made up of an security market, asset class, or market segment Thus the index can reflect the value or performance of a particular security market, asset class or market segment E.g. If the S&P 500 Index rises 2%, then that represents a 2% increase, of the 500 stocks that make up the S&P 500 equity Index Index Examples: * Dow Jones Industrial Average * Nikkei Stock Average * MSCI All Country World Index * Barclays Capital Global Aggregate Bond Index * FTSE EPRA/NAREIT Global Real Estate Index * HFRX Global Hedge Fund Index 2. WHAT DO WE USE INDICES FOR? * Measure a Market’s Return ...or Just Measure Market and Investor Sentiment * To Use the Index as an Investment Performance Benchmark Provide a Model Portfolio, or a Portfolio Selection Basket, for funds e.g. ‘Index Funds’ or ‘Large-Cap Funds’ * For Quantitative Functions e.g. to assist in calculating beta, expected returns or risk-adjusted returns 3. DIFFERENT TYPES OF INDICES a) ‘Price’ vs ‘Total Return’ Indexes * 'Price' Index: Calculated using on the market prices of the underlying, constituent securities * 'Total Return' Index: Calculated by ALSO including cash flow from the constituent securities, e.g. dividends and interest 3. DIFFERENT TYPES OF INDICES b) Weighting Methods How each constituent security impacts the final index value is dependent on its Weight in the Index. There are a number different weighting methods * ‘Price-weighted’ Index: Each security has an equal number of shares/units in the index e.g. 1x share of Apple, 1x share of Exxon Mobil, etc Thus, higher priced securities have greater weight, when shares/units are held equal i.e. ‘Price-weighted’ * ‘Market Cap-weighted’ Index: Each security's index weight should represent their actual % of total market value e.g. 30x shares of Apple (if 30% of market), 5x shares of T-Mobile (if 5% of market), etc Thus, larger market cap securities have greater weight i.e. ‘Market Cap-weighted’ * ‘Equal-weighted’ Index: Each security's index weight is the same and should have an equal dollar value in the index e.g. 10x shares of Apple (if AAPL @ $50), 20x shares of Netflix (if NFLX @ $25), etc Thus, smaller market cap securities have greater weight This methods means the Index Return is just the avg return of constituents Others: * Float-Adjusted Index Weights: e.g. ‘Market-float Weighted’ Index or a ‘Free Float’ Index * Fundamental Index Weights: e.g. ‘Revenue’, ‘Earnings’ or even ‘GDP’ weighted indexes 3. DIFFERENT TYPES OF INDICES c) Underlying Securities There’s virtually no restriction on the groups of underlying securities that make up the constituents of an index ...But the Key Ideas are: It’s not about ‘restrictions’ on what can be an index, it’s about ‘competition’ and ‘relevance’ to make the index popular & adopted. To have mass adoption an index must represent, or include, a material commonality or grouping useful/valuable for investors * Equity Market Indices: Broad Market, e.g. the whole market Multi Market, e.g. multiple countries Sector, e.g. technology Style, e.g. large-cap * Alternative Asset Indices: Real Estate Indexes Commodity Indexes Hedge Fund Indexes * Fixed Income Indices: Country, or Region Indices Sector Index Type of Issuer Index, e.g. Corporate or Government Maturity 4. REBALANCING AND RECONSTITUTION An Index is NOT static. They are frequently updated, e.g. quarterly, annually * Rebalancing: Update the Weights of the Index Constituents e.g. An Equal-Weighted Index needs rebalancing as weights become unequal over time * Reconstitution: Updating the Constituents, i.e. Adding and deleting them e.g. ASX200 has companies fall out of (and rise into) the top 200 market cap stocks This video was brought to you by AccoFina...

Index (economics)
 
06:15
In economics and finance, an index is a statistical measure of changes in a representative group of individual data points. These data may be derived from any number of sources, including company performance, prices, productivity, and employment. Economic indices (index, plural) track economic health from different perspectives. Influential global financial indices such as the Global Dow, and the NASDAQ Composite track the performance of selected large and powerful companies in order to evaluate and predict economic trends. The Dow Jones Industrial Average and the S&P 500 primarily track U.S. markets, though some legacy international companies are included. The Consumer Price Index tracks the variation in prices for different consumer goods and services over time in a constant geographical location, and is integral to calculations used to adjust salaries, bond interest rates, and tax thresholds for inflation. The GDP Deflator Index, or real GDP, measures the level of prices of all new, domestically produced, final goods and services in an economy. Market performance indices include the labour market index/job index and proprietary stock market index investment instruments offered by brokerage houses. Some indices display market variations that cannot be captured in other ways. For example, the Economist provides a Big Mac Index that expresses the adjusted cost of a globally ubiquitous Big Mac as a percentage over or under the cost of a Big Mac in the U.S. in USD (estimated: $3.57). The least relatively expensive Big Mac price occurs in Hong Kong, at a 52% reduction from U.S. prices, or $1.71 U.S. Such indices can be used to help forecast currency values. From this example, it would be assumed that Hong Kong currency is undervalued, and provides a currency investment opportunity. This video is targeted to blind users.

Index (publishing)
 
12:11
An index (plural: usually indexes, see below) is a list of words or phrases ('headings') and associated pointers ('locators') to where useful material relating to that heading can be found in a document. In a traditional back-of-the-book index the headings will include names of people, places and events, and concepts selected by a person as being relevant and of interest to a possible reader of the book. The pointers are typically page numbers, paragraph numbers or section numbers. In a library catalog the words are authors, titles, subject headings, etc., and the pointers are call numbers. Internet search engines, such as Google, and full text searching help provide access to information but are not as selective as an index, as they provide non-relevant links, and may miss relevant information if it is not phrased in exactly the way they expect.

Irregular Plural Nouns - foreign plurals | Types Of Nouns | Learn English with Kamal
 
05:50
Hello English Learners! Today I’m going to talk about another kind of irregular plural noun, and that is the foreign plural. Those are words that are borrowed into English from nearly every language with which it has come into contact and particularly for nouns from Latin, Greek, Hebrew, and French.

CppCon 2017: Tobias Fuchs “Multidimensional Index Sets for Data Locality in HPC Applications”
 
57:46
The Point of Views: Multidimensional Index Sets for Data Locality in HPC Applications http://CppCon.org — Presentation Slides, PDFs, Source Code and other presenter materials are available at: https://github.com/CppCon/CppCon2017 — In High Performance Computing, data access has complex implications and requires concepts that are fundamentally different from those provided in the STL. Iterators as we know them just are not enough. The proposed range concepts for the standard library are a significant improvement but are designed for the mental model of iterating and mapping values, not hierarchical domain decomposition. Even for a seemingly trivial array there are countless ways to partition and store its elements in distributed memory, and algorithms are required to behave and scale identically for all of them. It also does not help that most applications operate on multidimensional data structures where efficient access to neighborhood regions is crucial. Among HPC developers, it is therefore widely accepted that canonical iteration space and physical memory layout must be specified as separate concepts. For this, we use views based on multidimensional index sets, inspired by the proposed range concepts. In this session, we will explain the challenges when distributing container elements for thousands of cores and how modern C++ allows to achieve portable efficiency. As an HPC afficionado, you know you want this: copy( matrix_a | local() | block({ 2,3 }), matrix_b | block({ 4,5 }) ) If this does not look familiar to you: we give a gentle introduction to High Performance Computing along the way. — Tobias Fuchs: LMU Munich, Leibniz Supercomputing Centre, Research Associate Tobi is a freelancer in embedded systems and real-time applications for over 10 years, mostly for medical devices, and went back to academia for PhD studies in High Performance Computing at LMU Munich. He is the lead developer of the DASH C++ template library, a project of the German Research Foundation (DFG), and currently focuses on models and programming abstractions for data locality. As a hobby, he lures unsuspecting students into his C++ programming course to entrap them in category theory. — Videos Filmed & Edited by Bash Films: http://www.BashFilms.com

RailsConf 2016 -  Multi-table Full Text Search with Postgres By Caleb Thompson
 
27:19
Searching content across multiple database tables and columns doesn't have to suck. Thanks to Postgres, rolling your own search isn't difficult. Following an actual feature evolution I worked on for a client, we will start with a search feature that queries a single column with LIKE and build up to a SQL-heavy solution for finding results across multiple columns and tables using database views. We will look at optimizing the query time and why this could be a better solution over introducing extra dependencies which clutter your code and need to be stubbed in tests.

Table of Contents in Powerpoint
 
01:10
In this video tutorial we will show you how to create a table of contents in Powerpoint. Don't forget to check out our site http://howtech.tv/ for more free how-to videos! http://youtube.com/ithowtovids - our feed http://www.facebook.com/howtechtv - join us on facebook https://plus.google.com/103440382717658277879 - our group in Google+ It's an unfortunately reality that sometimes in a software update a useful feature is removed, this was the case with the table of contents feature in Powerpoint 2010. This tutorial will show you another way to create a table of contents in PowerPoint. Step # 1 -- Creating the Contents Page Slide Open the presentation that you want to add the table of contents to. Here we have a very simple four slide sample presentation. In the slide overview panel on the left click in between the first and second slide and click the dropdown part of the "New Slide" icon in the "Home" tab, choose the "Title and Content" option. Step # 2 -- Pasting the Titles Into the Contents Slide On the new slide enter a title, such as "Presentation Overview". Now, using the slide navigation pane click on the next slide and copy its title, navigate back to the contents slide and paste the title into the body of the presentation. Repeat this procedure for all the other slides in the presentation, placing each slide title onto a new line in the contents slide. That is how to create a table of contents in PowerPoint 2010.

Tlön, Uqbar, Orbis Tertius by Jorge Luis Borges
 
39:46
Tlön, Uqbar, Orbis Tertius by Jorge Luis Borges. Translated by Emece Editores, S.A. Narrated by Joseph Voelbel. This recording contains the occasional sound of the passing of automobiles. I like to imagine that they are a bustling city, just outside Borges' apartment window, on a temperate afternoon, while he narrates his most recently completed work to a group of a like-minded bibliophiles in some mid 20th century Buenos Aires, caught in amber. It appears, or at least according to my limited research it appears, that this is the first narration of Tlön, Uqbar, Orbis Tertius in English. I did find versions in French and Spanish. I must confess, due to the author's scrupulous preservation of detail, that in the ante-penultimate (third to las†) paragraph of the story, I pronounced the homonym 'minute' as if it were in reference to time, when in fact in was meant to be pronounced in relation to size. A simple yet ghastly oversight. Lastly, I might add, somewhat poetically, in the spirit of the last paragraph before the postscript (which was intended to be anachronistic, set seven years into the then future), which went: "Things become duplicated in Tlön; they also tend to become effaced and lose their details when they are forgotten. A classic example is the doorway which survived so long as it was visited by a beggar and disappeared at his death. At times some birds, a horse, have saved the ruins of an amphitheater." Is that by remembering and narrating this story, I hope, in some small way, to preserve the architecture of one of the greatest literary metagrobologists to ever grace a pen. P.S. This is AUDIO ONLY, so put on your screen savor and sweep your apartment, or doodle, you don't need to stare at the screen. Plus, a story like this, that goes this long, takes a certain contemplative demeanor. It's a moment to pause and reflect in life, maybe while doing something tedious, like paying bills or organizing a file cabinet. *Correction, volumes 56 and 57

CocoaHeads Rennes #14: La Programmation Responsive par Celedev
 
32:38
[Talk at CocoaHeads Rennes In French; subtitles available in English and French] Xcode, c'est très puissant, mais devoir recompiler, charger et relancer son application à chaque fois qu'on fait une modification dans le code, ça devient vite fastidieux. Si les changements dans le code pouvaient s'appliquer en temps réel dans l'application, on gagnerait pas mal de temps qu'on pourrait consacrer à expérimenter des idées nouvelles et à améliorer nos apps. Un rêve ? Plus vraiment. Celedev, une startup rennaise, a développé un environnement de développement pour iOS entièrement conçu autour de cette idée de Programmation Responsive. Jean-Luc Jumpertz (créateur de Celedev) est venu nous présenter cet outil et nous faire une petite démo.

Islamic banking and finance | Wikipedia audio article
 
02:18:51
This is an audio version of the Wikipedia Article: Islamic banking and finance Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago. Learning by listening is a great way to: - increases imagination and understanding - improves your listening skills - improves your own spoken accent - learn while on the move - reduce eye strain Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone. You can find other Wikipedia audio articles too at: https://www.youtube.com/channel/UCuKfABj2eGyjH3ntPxp4YeQ You can upload your own Wikipedia articles through: https://github.com/nodef/wikipedia-tts "The only true wisdom is in knowing you know nothing." - Socrates SUMMARY ======= Islamic banking or Islamic finance (Arabic: مصرفية إسلامية‎) or sharia-compliant finance is banking or financing activity that complies with sharia (Islamic law) and its practical application through the development of Islamic economics. Some of the modes of Islamic banking/finance include Mudarabah (profit-sharing and loss-bearing), Wadiah (safekeeping), Musharaka (joint venture), Murabahah (cost-plus), and Ijara (leasing). Sharia prohibits riba, or usury, defined as interest paid on all loans of money (although some Muslims dispute whether there is a consensus that interest is equivalent to riba). Investment in businesses that provide goods or services considered contrary to Islamic principles (e.g. pork or alcohol) is also haraam ("sinful and prohibited"). These prohibitions have been applied historically in varying degrees in Muslim countries/communities to prevent un-Islamic practices. In the late 20th century, as part of the revival of Islamic identity, a number of Islamic banks formed to apply these principles to private or semi-private commercial institutions within the Muslim community. Their number and size has grown, so that by 2009, there were over 300 banks and 250 mutual funds around the world complying with Islamic principles, and around $2 trillion was sharia-compliant by 2014. Sharia-compliant financial institutions represented approximately 1% of total world assets, concentrated in the Gulf Cooperation Council (GCC) countries, Iran, and Malaysia. Although Islamic banking still makes up only a fraction of the banking assets of Muslims, since its inception it has been growing faster than banking assets as a whole, and is projected to continue to do so.The industry has been lauded for returning to the path of "divine guidance" in rejecting the "political and economic dominance" of the West, and noted as the "most visible mark" of Islamic revivalism, its most enthusiastic advocates promise "no inflation, no unemployment, no exploitation and no poverty" once it is fully implemented. However, it has also been criticized for failing to develop profit and loss sharing or more ethical modes of investment promised by early promoters, and instead selling banking products that "comply with the formal requirements of Islamic law", but use "ruses and subterfuges to conceal interest", and entail "higher costs, bigger risks" than conventional (ribawi) banks.

Concrete representations involving the Pauli matrices and more general gamma matrices are an integral part of the physical description of fermions, which behave as spinors. For the three lightest quarks, there is a group-theoretical representation involving the special unitary group SU(3); for their calculations, physicists use a convenient matrix representation known as the Gell-Mann matrices, which are also used for the SU(3) gauge group that forms the basis of the modern description of strong nuclear interactions, quantum chromodynamics.
