In applied Statistics and Machine Learning, Data Visualization is one of the most important skills. Data visualization provides an important suite of tools for identifying a qualitative understanding. This can be helpful when we try to explore the dataset and extract some information to know about a dataset and can help with identifying patterns, corrupt data, outliers, and much more. If we have a little domain knowledge, then data visualizations can be used to express and identify key relationships in plots and charts that are more helpful to yourself and stakeholders than measures of association or significance. In this article, we will be discussing some of the basic charts or plots that you can use to better understand and visualize your data.
Kate Crawford studies the social and political implications of artificial intelligence. She is a research professor of communication and science and technology studies at the University of Southern California and a senior principal researcher at Microsoft Research. Her new book, Atlas of AI, looks at what it takes to make AI and what’s at stake as it reshapes our world. You’ve written a book critical of AI but you work for a company that is among the leaders in its deployment. How do you square that circle?
The internet is intangible, and because you can’t see it, it can be hard to comprehend its sheer vastness. As well, it’s difficult to gauge the relative size of different web properties. However, this map of the internet by Halcyon Maps offers a unique solution to these problems. Inspired by the look and design of historical maps, this graphic provides a snapshot of the current state of the World Wide Web, as of April 2021. Let’s take a closer look!
What does it mean for one of the world’s most recognizable retail brands to go digital? For almost 80 years, IKEA has been in the very analogue business of selling its distinct brand of home goods to people. Three years ago, IKEA Retail (Ingka Group) hired Barbara Martin Coppola — a veteran of Google, Samsung, and Texas Instruments — to guide the company through a digital transformation and help it enter the next era of its history. HBR spoke with Martin Coppola about the particular challenge of transformation at a legacy company, how to sustain your culture when you’re changing almost everything, and how her 20 years in the tech industry prepared her for this task.
GPs in England have been told to hand over all patient data to NHS Digital – potentially to be exploited for corporate profit. GP practices in England have been instructed to hand over their patients’ entire medical histories with just six weeks’ notice. Like many GPs, I’m very concerned about the implications this has for my patients. A growing number of us in London have taken taken the decision to pull the plug on the new data-sharing programme with NHS Digital and refuse to hand over patient records.
It's essential to understand data warehousing depending on your requirements and business. Many organizations struggle in selecting the data warehouse that suits them. Hence, people are opting for the BigQuery/Snowflake course to understand data warehousing. Here, we are going to compare the two topmost data warehouses: BigQuery and Snowflake.
The number of devices connected through the Internet of Things (IoT) is increasing rapidly. Statista estimates that there will be about 50 million IoT-connected devices in use across the world by 2030. And these interconnected devices and enterprise systems will generate vast amounts of data. And, most of this data will be stored and analyzed on the cloud.The number of devices connected through the Internet of Things (IoT) is increasing rapidly.

Whether you’re trying to measure how effectively you’re acquiring users or trying to make sense of in-product user journeys, funnel analysis is a cornerstone of understanding campaign performance and product health. But before we get ahead of ourselves, let’s take a look at what funnel analysis even is and how Mixpanel can help you make the most of it.
Machine learning involves using an algorithm to learn and generalize from historical data in order to make predictions on new data. This problem can be described as approximating a function that maps examples of inputs to examples of outputs. Approximating a function can be solved by framing the problem as function optimization. This is where a machine learning algorithm defines a parameterized mapping function (e.g. a weighted sum of inputs) and an optimization algorithm is used to fund the values of the parameters (e.g. model coefficients) that minimize the error of the function when used to map inputs to outputs.
Introduction Master Python or R Essentials NowPractice 5–10 Machine Learning Algorithms Explain Modeling to a Non-Data Scientist While there may be a few approaches out there to data science from scratch, I wanted to give my take on it, with the thought of what I would do differently in mind if I were to start over. In my case, I started from scratch, majoring in a field that was not data science, to begin with for my undergraduate degree.
A thorough understanding of the basic components of programming language is vital in the development of any code. This article outlines all the fundamental concepts of the Python language. Just like how parts of speech form a basic building block of the English language, the following components form Python’s parts of speech.
Do you own an Echo Studio, an Echo Dot, or a Ring Floodlight Cam? If so, Amazon is about to introduce your device to a new type of network it calls Sidewalk, which is meant to help extend the range of its low-bandwidth devices (so that if your network goes down, for example, your Dot can piggyback on your neighbors’), and also to make location devices such as Tile more efficient.
Use interactive charts to explore a deeply-nested inflation datasetShowing data broken down into categories is quite easy — just use a humble bar chart or pie chart (although there’s a 100-year old debate about which is best). But what if each category has sub-categories? And those sub-categories have sub-sub-categories? This is a common data pattern found in many domains including filesystems, biology, and economics.
A look into how software developers are taking on more responsibility, and what this means for traditional tech rolesPhoto by Peter Gombos on UnsplashHistorically, IT departments have been structured across lines of technology, such as the app, UX, and database teams. More recently, the 2-pizza DevOps team has emerged and evangelized restructuring around lines of business. A single team is now responsible for a particular business capability end-to-end. This has ushered in the era of the full-stack developer — an engineer who can contribute to any facet of the system.
Google is constantly working on its algorithms to improve search quality and give users the best possible answers to their search queries. However, it would be naive to think that algorithms can do the whole job flawlessly. In addition to algorithms, Google also has a Search Quality team that manually reviews websites that show signs of unethical behavior. In fact, it is a full-time job for the Google Search Quality team to decide whether a particular website has or has not violated the rules.
In Google Analytics, you can define any actions that are valuable to your business as a conversion. For example, someone completing your contact form, signing up for your newsletter, or making a purchase could all be considered conversions. And your conversion rate is the percentage of people (based on either sessions or users) who visit your website and complete your desired action, compared to your total number of website visitors.
Master data management definitionMaster data management (MDM) is a set of disciplines, processes, and technologies used to manage an organization’s master data. Master data is data about business entities or objects (customers, suppliers, employees, products, cost centers, etc.) around which business is conducted. It is used to provide context to transactional data and is typically scattered around the business in various spreadsheets, applications, and even physical media.
I’m starting to see the big consultancies and advisory services coming out with their lists of “what’s hot” from a data and analytics perspective. While I may not have the wide purview of these organizations, I certainly do work with some interesting organizations who are at various points in their data and analytics journey. With that in mind, I’d like to share my perspective as to what I think will be big in the area of data and analytics over the next 18 months.
Technology gave rise to Data Analytics, but it can also become the cause of several privacy issues. Data Analytics is progressively changing the world. Businesses, governments, and different organizations are unlocking their true potential with the help of Data Analytics. Real-time analytics provides swift solutions to complex problems, enabling faster decision-making, and accelerating investments across all industrial sectors.
Sentiment Analysis — Comparing 3 Common Approaches: Naive Bayes, LSTM, and VADERA Study on Strengths and Drawbacks for the Different Approaches (With Sample Code) Sentiment Analysis, or Opinion Mining, is a subfield of NLP (Natural Language Processing) that aims to extract attitudes, appraisals, opinions, and emotions from text. Inspired by the rapid migration of customer interactions to digital formats e.g. emails, chat rooms, social media posts, comments, reviews, and surveys, Sentiment Analysis has become an integral part of analytics organizations must perform to understand how they are positioned in the market. To be clear, Sentiment Analysis isn’t a novel concept.
