How do you choose products in stores?

SAS corporate blog Data Mining *Machine learning *Social networks and communities
Translation

The most important single ingredient in the formula of success is knowing how to get along with people. Theodore Roosevelt

In the previous article I tried to cover the basics of pricing analytics. Now I'd like to talk about something more interesting.

Have you ever thought about why you choose certain products in stores, why you prefer them to other similar ones? Many shopping trips are spontaneous, so it's probably impossible to give a clear answer for all the times you go shopping. But the general idea is obvious: you go shopping for a specific reason (to get food, a gadget, for entertainment, to play blackjack). In this article I'm going to use available data from grocery retailers to talk about how a set of basic logical assumptions and community analysis can help us determine the way customers choose products.

Marketing with ML decision making

Machine learning *Web analytics *Internet marketing
Sandbox
Backlog prioritization leads to the choice between strategies. Each one has its metrics. There is a requirement to choose the most important one. ML scoring is a solution when non linearity exists and economy is nonlinear. See introduction here. Two groups are considered. First (I) corresponds to web conversion {bounce rate, micro conversion, time, depth}. Second (II) corresponds to attraction of new visitors from organic channel {visits, viewers, views}. The target function is a number of commercial offers per day. The task is to reduce the dimension to get the optimal simple strategy. In this case online/offline B2B channels can't be separated: market is thin and new customers may have some information about 'the brand' from both channels. Therefore statistical evaluation is closer to reality than direct CJM tracking in this case.

A drawing bot for realizing everyday scenes and even stories

Microsoft corporate blog Open source *GitHub Machine learning *Artificial Intelligence

Drawing bot


If you were asked to draw a picture of several people in ski gear, standing in the snow, chances are you’d start with an outline of three or four people reasonably positioned in the center of the canvas, then sketch in the skis under their feet. Though it was not specified, you might decide to add a backpack to each of the skiers to jibe with expectations of what skiers would be sporting. Finally, you’d carefully fill in the details, perhaps painting their clothes blue, scarves pink, all against a white background, rendering these people more realistic and ensuring that their surroundings match the description. Finally, to make the scene more vivid, you might even sketch in some brown stones protruding through the snow to suggest that these skiers are in the mountains.


Now there’s a bot that can do all that.

Improve your mobile application using machine learning technology

Development of mobile applications *Machine learning *
Sandbox
Today, even mobile application developing company has begun to consolidate ML related to other cutting edge technologies, for example, AI and predictive analysis. This is on the grounds that ML empowers mobile applications to learn, adjust, and improve after some time.

It’s an incredible accomplishment when you consider the way that changes requested an express order from designers for gadgets to execute a particular activity. At the point when this was the standard, software engineers needed to estimate and record for each conceivable situation (and this was a fantastic test).

Be that as it may, with ML in portable applications, we have removed the speculating game from the condition. It can likewise upgrade User Experience (UX) by understanding client conduct. So you can wager that ML in versatile won’t be restricted to voice associates and chatbots.

Artificial neural networks explained in simple words

Machine learning *Popular science Artificial Intelligence Brain
image

When I used to start a conversation about neural networks over a bottle of beer, people were casting glances at me of what seemed to be fear; they grew sad, sometimes with their eyelid twitching. In rare cases, they were even eager to take refuge under the table. Why? These networks are simple and instinctive, actually. Yes, believe me, they are! Just let me prove this is true!


Suppose there are two things I’m aware of about the girl: she looks pretty to my taste or not, and I have lots to talk about with her or I haven’t. True and false will be one and zero respectively. We’ll take similar principle for appearance. The question is: “What girl I’ll fall in love with, and why?”


We also can think it straight and uncompromisingly: “If she looks pretty and there’s plenty to talk about, then I will fall in love. If neither is true, then I quit”.


But what if I like the lady but there’s nothing to talk about with her? Or vice versa?

Build tools in machine learning projects, an overview

Machine learning *Build automation *
I was wondering about machine learning/data science project structure/workflow and was reading different opinions on the subject. And when people start to talk about workflow they want their workflows to be reproducible. There are a lot of posts out there that suggest to use make for keeping workflow reproducible. Although make is very stable and widely-used I personally like cross-platform solutions. It is 2019 after all, not 1977. One can argue that make itself is cross-platform, but in reality you will have troubles and will spend time on fixing your tool rather than on doing the actual work. So I decided to have a look around and to check out what other tools are available. Yes, I decided to spend some time on tools.

This post is more an invitation for a dialogue rather than a tutorial. Perhaps your solution is perfect. If it is then it will be interesting to hear about it.

In this post I will use a small Python project and will do the same automation tasks with different systems:


There will be a comparison table in the end of the post.

Google News and Leo Tolstoy: visualizing Word2Vec word embeddings using t-SNE

VK corporate blog Python *Big Data *Data visualization Machine learning *

Everyone uniquely perceives texts, regardless of whether this person reads news on the Internet or world-known classic novels. This also applies to a variety of algorithms and machine learning techniques, which understand texts in a more mathematical way, namely, using high-dimensional vector space.

This article is devoted to visualizing high-dimensional Word2Vec word embeddings using t-SNE. The visualization can be useful to understand how Word2Vec works and how to interpret relations between vectors captured from your texts before using them in neural networks or other machine learning algorithms. As training data, we will use articles from Google News and classical literary works by Leo Tolstoy, the Russian writer who is regarded as one of the greatest authors of all time.

We go through the brief overview of t-SNE algorithm, then move to word embeddings calculation using Word2Vec, and finally, proceed to word vectors visualization with t-SNE in 2D and 3D space. We will write our scripts in Python using Jupyter Notebook.

We're in UltraHD Morty! How to watch any movie in 4K

Working with video *Machine learning *DIY
You’ve probably heard about Yandex’s DeepHD technology they once used to improve the quality of old Soviet cartoons. Unfortunately, it’s not public yet, and we, regular programmers, don’t have the dedication to write our own solution. But I personally really wanted to watch Rick and Morty on my 2880x1880 Retina display. And I was deeply disappointed, as even 1080p video (the highest available for this series) looks really blurry on a Retina display! Don’t get me wrong, 1080p is often good enough, but Retina is designed in such a way that an animation with its pronounced outlines in 1080p looks awfully blurry, like 480p on a FullHD monitor.

I decided I want to see Rick and Morty in 4K, even though I can’t write neural networks. And, amazingly, I found a solution. You don’t even need to write any code: all you need is around 100GB of free space and a bit of patience. The result is a sharp 4K image that looks better than any interpolation.

Detecting Web Attacks with a Seq2Seq Autoencoder

Positive Technologies corporate blog Information Security *Machine learning *
image

Attack detection has been a part of information security for decades. The first known intrusion detection system (IDS) implementations date back to the early 1980s.

Nowadays, an entire attack detection industry exists. There are a number of kinds of products—such as IDS, IPS, WAF, and firewall solutions—most of which offer rule-based attack detection. The idea of using some kind of statistical anomaly detection to identify attacks in production doesn’t seem as realistic as it used to. But is that assumption justified?

.NET, TensorFlow, and the windmills of Kaggle — the journey begins

Sport programming *.NET *Data Mining *C# *Machine learning *
Recovery mode
Tutorial
This is a series of articles about my ongoing journey into the dark forest of Kaggle competitions as a .NET developer.

I will be focusing on (almost) pure neural networks in this and the following articles. It means, that most of the boring parts of the dataset preparation, like filling out missing values, feature selection, outliers analysis, etc. will be intentionally skipped.

The tech stack will be C# + TensorFlow tf.keras API. As of today it will also require Windows. Larger models in the future articles may need a suitable GPU for their training time to remain sane.

Progress and hype in AI research

Machine learning *Artificial Intelligence
Sandbox

The biggest issue with AI is not that it is stupid but a lack of definition for intelligence and hence a lack of formal measure for it [1a] [1b].


Turing test is not a good measure because gorilla Koko [2a] and bonobo Kanzi [2b] wouldn't pass though they could solve more problems than many disabled human beings.


It is quite possible that people in the future might wonder why people back in 2019 thought that an agent trained to play a fixed game in a simulated environment such as Go had any intelligence [3a] [3b] [3c] [3d] [3e] [3f] [3g] [3h].


Intelligence is more about applying/transferring old knowledge to new tasks (playing Quake Arena good enough without any training after mastering Doom) than compressing agent's experience into heuristics to predict a game score and determining agent's action in a given game state to maximize final score (playing Quake Arena good enough after million games after mastering Doom) [4].


Human intelligence is about ability to adapt to the physical/social world, and playing Go is a particular adaptation performed by human intelligence, and developing an algorithm to learn to play Go is a more performant one, and developing a mathematical theory of Go might be even more performant.

Creator of while True: learn() on programming in game development, VR issues and machine learning simulation

Game development *Machine learning *Game design *AR and VR Interview
Translation


A few years ago I had a feeling that Oleg Chumakov (then working at the game studio Nival) was the most famous programmer in the game development industry. He was giving speeches, hosted Gamesjams and frequently showed up on the podcast How games are made.

When VR hit the market, Oleg was chosen to lead the company’s new department — NivalVR. But, as you probably know, VR didn’t quite take off as much as people expected.

I kind of moved to other to other things in life and stopped keeping up with game development for a while, but after getting into it again I noticed that things were looking up for Oleg’s team. Now it’s called Luden.io, and their machine learning expert simulator, while True: learn() became a huge hit in its admittedly small niche. Lots of cool stories are happening around the game and the team.

We decided to do an interview with Oleg, but I couldn’t stick to one topic — his life up to this moment has been, for the lack of a better word, “interesting”. He’s seen it all. And, to ensure that a programmer could talk about programming without fear of looking too “nerdy”, the interview was conducted by my friend, colleague and an experienced developer of its own fillpackart.
