A couple of years back, I worked on an Information Extraction (IE) tool called SEER, that helps users extract data from a document. For instance, an investigator wishes to extract all increases and decreases of offenses from a dataset of FBI press releases.Image by Author.SEER learns to automatically extract data from user-given examples of text highlights. It learns the patterns in the highlighted texts and generates extraction rules that match and extract the desired target texts.Each row is an extraction rule. And each…

The inertial navigation domain is considered a very classical one. It aims to provide us with navigation solutions (position, velocity, and orientation) using (low-graded) inertial sensors and accurate (low frequency) sensors, like the GPS receiver. A question has arisen about how powerful Deep Learning tools can boost this classical domain.Three years ago, I started asking myself if there is a value in combining Machine Learning, generally, and Deep Learning (DL), particularly, in the classical inertial navigation system…

Coffee Data ScienceImaging analysis of filter basketsI started looking at filter baskets a few years ago, and I looked at how random extremely large or small holes were spatially arranged. I wanted to understand if that could be used to help explain why some baskets performed better than others.So when I got a CoffeeJack, I took the same approach. I compared it to Kompresso because Kompresso has been by defacto travel machine for three years. I have been surprised that for the same grind, water, and pre-infusion,…

Messages on social media are both a good thing and a bad thing. There’s always the chance that someone can randomly send you images that you don’t want to see via message. This is why Instagram is developing a nudity filter for its messaging platform.When you post a picture to Twitter or Reddit, you have the ability to mark it as inappropriate or disturbing. Thus, the image will be hidden behind a shade, and you’ll only be able to see it if you tap on the view button.It seems like Instagram wants to make this an…

Five days after Joan Washington, Richard E Grant’s wife of 35 years, died from lung cancer in September 2021, he got a phone call from a number he didn’t recognise. Grant and his daughter Olivia, then 32, were driving around, dealing with what he describes in his new memoir as “the bureaucracy of death”: filling out government forms, picking up hymn sheets for the funeral – all the banalities that come rushing at you when you’ve just lost the love of your life. Then the number flashed up. Olivia advised him not to answer,…

Are you tired of seeing spam texts tangled up with texts from people in your contacts list? Or perhaps you're tired of trying to read a text from someone close to you and seeing a spam text come on top of it in the process. In case you haven't noticed anything else new with iOS 16 in the last day or so, a brand-new feature enables you to separate the two: Filter Unknown Senders. Filter Unknown Senders is not exactly a "brand-new feature" so much as it is a relatively new one. It has been around since iOS 14, but…

Tech giant Google is bringing a new app review policy to make app ratings and reviews as genuine as possible in the Play Store.The latest change will hold up user-submitted reviews and ratings by around 24 hours before they go public, assuming they're from real people, reports Android Central.Read AlsoAs per the report, the tech giant aims for the new policy to detect suspicious ratings and reviews on Android apps."To allow us to automatically detect suspicious Ratings or Reviews activity, we are introducing a delay of…

Snapchat’s augmented reality filters are a major draw for users of the social media app.Image: Neilson Barnard (Getty Images)Snapchat has come under scrutiny after a filter released on the app resembled face tattoos that are sacred to the Māori people, who are the indigenous people of New Zealand.Snapchat and augmented reality filters go together like peanut butter and jelly—the company unveiled their augmented reality face filters as early as the autumn of 2015. The social media platform has recently come under fire,…

Sometimes I see queries that prepare a column in an early stage only to use that column for filtering in a later stage. Or something gets filtered with HAVING that could have been filtered with WHERE earlier. This slows down queries and increases processing costs. Let’s have a look at what we can do about this!Here is an exemplary scenario where the same output is created — but one time the query is optimized by filtering earlier:Amount of data processed from Common Table Expression (CTE) to final Output Query (Image by…
