Description:
Synthetic data will drive the next wave of deployment and application of deep learning in the real world across a variety of problems involving speech recognition, image classification, object recognition and language. All industries and companies will benefit, as synthetic data can create conditions through simulation, instead of authentic situations (virtual worlds enable you to avoid the cost of damages, spare human injuries, and other factors that come into play); unparalleled ability to test products, and interactions with them in any environment.
Join us for this introductory session to learn more about how Generative Adversarial Networks (GAN) are successfully used to improve data generation. We will cover specific real-world examples where customers have deployed GAN to solve challenges in healthcare, space, transportation, and retail industries.

For many years, the main goal of the Netflix personalized recommendation system has been to get the right titles in front each of our members at the right time. With a catalog spanning thousands of titles and a diverse member base spanning over a hundred million accounts, recommending the titles that are just right for each member is crucial. But the job of recommendation does not end there. Why should you care about any particular title we recommend? What can we say about a new and unfamiliar title that will pique your interest? How do we convince you that a title is worth watching? Answering these questions is critical in helping our members discover great content, especially for unfamiliar titles. One way to do this is to consider the artwork or imagery we use to visually portray each title. If the artwork representing a title captures something compelling to you, then it acts as a gateway into that title and gives you some visual “evidence” for why the title might be good for you. Selecting good artwork is important because it may be the first time a member becomes aware of a title (and sometimes the only time), so it must speak to them in a meaningful way. In this talk, we will present an approach for personalizing the artwork we show for each title on the Netflix homepage. We will look at how to frame this as a machine learning problem using contextual multi-armed bandits in a recommendation system setting. We will also describe the algorithmic and system challenges involved in getting this type of approach for artwork personalization to succeed at Netflix scale. Finally, we will discuss some of the future opportunities that we see to expand and improve upon this approach.

Crypto wallets are a type of digital wallet specifically used for storing digital currencies. These are basically applications that can help you access blockchain platforms and help you retrieve and use your crypto assets.
There are usually two types of crypto wallets - Hot Wallets and Cold Wallets. Hot wallets are a type of crypto wallets that are always connected to the internet. This type of wallet is less secured than a Cold wallet. Cold wallets are a type of crypto wallets that are offline. Typically, they serve as vaults for your important documents and assets.
You need to choose a type of wallet based on your needs. However, to fully understand how this works, you have to learn about the underlying working process of the wallets. Here, 101 Blockchains can greatly help you out. We have courses that will specifically target your needs and help you understand the mechanism behind blockchain technology-based wallets.

This presentation gives a brief introduction to blockchain and proposes a unified analytical framework for trustable machine learning and automation running with blockchain.
At Netflix, we've spent a lot of time thinking about how we can make our analytics group move quickly. Netflix's Data Engineering & Analytics organization embraces the company's culture of "Freedom & Responsibility".
How does a company with a $40 billion market cap and $6 billion in annual revenue keep their data teams moving with the agility of a tiny company?
How do hundreds of data engineers and scientists make the best decisions for their projects independently, without the analytics environment devolving into chaos?
We'll talk about how Netflix equips its business intelligence and data engineers with:
the freedom to leverage cloud-based data tools - Spark, Presto, Redshift, Tableau and others - in ways that solve our most difficult data problems
the freedom to find and introduce right software for the job - even if it isn't used anywhere else in-house
the freedom to create and drop new tables in production without approval
the freedom to choose when a question is a one-off, and when a question is asked often enough to require a self-service tool
the freedom to retire analytics and data processes whose value doesn't justify their support costs

RecSys 2020 A Human Perspective on Algorithmic Similarity Schendel 9-2020Zachary Schendel
In the Netflix user interface (UI), when a row or UI element is named “Because you Watched...”, “More Like This”, or “Because you added to your list”, the overarching goal is to recommend a movie or TV show that a member might like based on the fact that they took a meaningful action on a source item. We have employed similar recommendations in many UI elements: on the homepage as a row of recommendations, after you click into a title, or as a piece of information about why a member should watch a title.
From an algorithmic perspective, there are many ways to define a “successful” similar recommendation. We sought to broaden that definition of success. To this end, the Consumer Insights team recently completed a suite of research projects to explore the intricacies of member perceptions of similar recommendations. The Netflix Consumer Insights team employs qualitative (e.g., in-depth interviews) and quantitative (e.g., surveys) research methods, interfacing directly with Netflix members to uncover pain points that can inspire new product innovation. The research concluded that, while the typical member believes movies are broadly similar when they share a common genre or theme, similarity is more complex, nuanced, and personal than we might have imagined. The vernacular we use in the UI implies that there should be at least some kind of relationship between the source item and the recommendations that follow. Many of our similar recommendations felt “out of place”, mostly because the relationship between the source item and the recommendation was unclear or absent. When similar recommendations tell a completely misleading, incorrect, or confusing story, member trust can be broken.
We will structure the presentation around three new insights that our research found to have an influence on the perception of similarity in the context of Netflix as well as the research methods used to uncover those insights. First, the reason a member loves a given movie will vary. For example, do you want to watch other baseball movies like Field of Dreams, or would you prefer other romances like Field of Dreams? Second, members are more or less flexible about how similar a recommendation actually needs to be depending on the properties of and their interactions with the canvas containing the recommendation. For example, a Because You Watched row on the homepage implies vaguer similarity while a More Like This gallery behind a click into the source item implies stricter similarity. Finally, even when we held the UI element constant, we found that similar recommendations are only valuable in some contexts. After finishing a movie, a member might prefer a similar recommendation one day and a change of pace the next. Research methods discussed will include Inverse Multi-Dimensional Scaling [1], survey experimentation, and ways to apply qualitative research to improve algorithmic recommendations.

Nowadays everyone uses their personal identification documents on a regular basis, which gets shared with third parties without their explicit consent and stored at an unknown location. Companies such as government institutions, banks, credit agencies and other financial organizations are considered to be the weakest point in the current identity management system as they are unfortified to theft and hacking of data. Although the financial services sector have been seeking solutions for identity problem for a long time, it is only now that a viable solution has arrived in form of blockchain. KYC Know Your Customer using Blockchain eliminates the repeated KYC checks that banks currently perform by maintaining a common secure database in a blockchain. The nature of a blockchain ensures that unauthorized changes to the data are automatically invalidated. The proof of reputation concept makes the verification process more robust and secure. Decentralized computing architecture, blockchain will allow for the accumulation of data from multiple authoritative service provider into a single immutable, cryptographically secured and validated database. Blockchain KYC solution take advantages of a secure, public digital ledger to give almost instantaneous and truly secure verification of identity. Due to the immutable and unalterable nature of the record kept in the blockchain, fraud could become a thing of the past.

Déjà Vu: The Importance of Time and Causality in Recommender SystemsJustin Basilico
Talk at RecSys 2017 in Como, Italy on 2017-08-29.
Abstract:
Time plays a key role in recommendation. Handling it properly is especially critical when using recommender systems in real-world applications, which may not be as clear when doing research with historical data. In this talk, we will discuss some of the important challenges of handling time in recommendation algorithms at Netflix. We will focus on challenges related to how our users, items, and systems all change over time. We will then discuss some strategies for tackling these challenges, which revolves around proper treatment of causality in our systems.
Bitcoin is a decentralized electronic cash system using peer-to-peer networking to enable payments between parties without relying on mutual trust. It was first described in a paper by Satoshi Nakamoto (widely presumed to be a pseudonym) in 2008. Payments are made in bitcoins (BTC's), which are digital coins issued and transferred by the Bitcoin network.
In the near future, privacy-preserving authentication methods will flood the market, and they will be based on Zero-Knowledge Proofs. IBM and Microsoft invested in these solutions many years ago.
At Netflix we take context of the member seriously.
In this keynote talk we will see how modeling contextual factors such as time or device can help members to find the right content at the right moment
At the end, the goal is to maximize member satisfaction and retention
These slides will go through which contextual factors matters for the video service and why we choose to use them or not.

Using Tweets for Understanding Public Opinion During U.S. Primaries and Predi...Monica Powell
Abstract
Using social media for political analysis, especially during elections, has become popular in the past few years where many researchers and media now use social media to understand the public opinion and current trends. In this paper, we investigate methods for using Twitter to analyze public opinion and to predict U.S. Presidential Primary Election results. We analyzed over 13 million tweets from February 2016 to April 2016 during the primary elections, and we looked at tweets that mentioned either Hillary Clin- ton, Bernie Sanders, Donald Trump or Ted Cruz. First, we use the methods of sentiment analysis, geospatial analysis, net- work analysis, and visualizations tools to examine public opinion on twitter. We then use the twitter data and analysis results to propose a prediction model for predicting primary election results. Our results highlight the feasibility of using social media to look at public opinion and predict election results.
Twitter Based Sentiment Analysis of Each Presidential Candidate Using Long Sh...CSCJournals
In the era of technology and internet, people use online social media services like Twitter, Instagram, Facebook, Reddit, etc. to express their emotions. The idea behind this paper is to understand people’s emotion on Twitter and their opinion towards Presidential Election 2020. We collected 1.2 million tweets in total with keyword like “RealDonaldTrump”, “JoeBiden”, “Election2020” and other election related keywords using Twitter API and then processed them with natural language processing toolkit. A Bidirectional Long Short-Term Memory (BiLSTM) model has been trained and we have achieved 93.45% accuracy on our test dataset. We then used our trained model to perform sentiment analysis on the rest of our dataset. With the sentiment analysis results and comparison with 2016 Presidential Election, we have made predictions on who could win the US Presidential Election in 2020 with pre-election twitter data. We have also analyzed the impact of COVID-19 on people’s sentiment about the election.
Analyzing Political Sentiment of Indic Languages with TransformersIJCI JOURNAL
This paper presents an analysis of sentiment on Twitter towards the Karnataka elections held in 2023, utilizing transformer-based models specifically designed for sentiment analysis in Indic languages. Through an innovative data collection approach involving a combination of novel methods of data augmentation, online data preceding the election was analyzed. The study focuses on sentiment classification, effectively distinguishing between positive, negative, and neutral posts, while specifically targeting the sentiment regarding the loss of the Bharatiya Janata Party (BJP) or the win of the Indian National Congress (INC). Leveraging high-performing transformer architectures, specifically IndicBERT, coupled with specifically fine-tuned hyperparameters, the AI models employed in this study achieved remarkable accuracy in predicting the the INC’s victory in the election. The findings shed new light on the potential of cutting-edge transformer-based models in capturing and analyzing sentiment dynamics within the Indian political landscape. The implications of this research are far-reaching, providing invaluable insights to political parties for informed decision-making and strategic planning in preparation for the forthcoming 2024 Lok Sabha elections in the nation.
The Party is Over Here: Structure and Content in the 2010 ElectionAvishay Livne
In this work, we study the use of Twitter by House, Senate and gubernatorial candidates during the midterm (2010) elections in the U.S. Our data includes almost 700 candidates and over 690k documents that they produced and cited in the 3.5 years leading to the elections. We utilize graph and text mining techniques to analyze differences between Democrats, Republicans and Tea Party candidates, and suggest a novel use of language modeling for estimating content cohesiveness. Our findings show significant differences in the usage patterns of social media, and suggest conservative candidates used this medium more effectively, conveying a coherent message and maintaining a dense graph of connections. Despite the lack of party leadership, we find Tea Party members display both structural and language-based cohesiveness. Finally, we investigate the relation between network structure, content and election results by creating a proof-of-concept model that predicts candidate victory with an accuracy of 88.0%.

Techniques to optimize the pagerank algorithm usually fall in two categories. One is to try reducing the work per iteration, and the other is to try reducing the number of iterations. These goals are often at odds with one another. Skipping computation on vertices which have already converged has the potential to save iteration time. Skipping in-identical vertices, with the same in-links, helps reduce duplicate computations and thus could help reduce iteration time. Road networks often have chains which can be short-circuited before pagerank computation to improve performance. Final ranks of chain nodes can be easily calculated. This could reduce both the iteration time, and the number of iterations. If a graph has no dangling nodes, pagerank of each strongly connected component can be computed in topological order. This could help reduce the iteration time, no. of iterations, and also enable multi-iteration concurrency in pagerank computation. The combination of all of the above methods is the STICD algorithm. [sticd] For dynamic graphs, unchanged components whose ranks are unaffected can be skipped altogether.
