Artificial neural networks explained in simple words

Reading time7 min

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?

How to make possible micro-payments in your app

Reading time8 min
Views5.3K

This week I spent coding my very first public pet-app based on Telegram chat bot which acts as a Bitcoin wallet and allows to send and receive tips between Telegram users and other so-called “Lightning Apps”. I assume that you are familiar with Bitcoin & Telegram in general, i’ll try to post short and without deep jump into details. More resources about Bitcoin can be found here and Telegram is simply an instant messenger that allows you to create your custom apps (chat-bots) using their platform.


What are the key points of such app?


  • Allows to rate other users ideas and answers with real value instead of
    ‘virtual likes’. This brings online conversation to completely new level
  • Real example of working micro-payment app which can act with other entities
    over internet using open protocol
  • All the modules are open-source projects and can be easy re-used and adjusted
    for your own project. App does not relay on third-party commercial services.
    Even it falls under e-commerce field, which is currently almost closed, the app
    is based on open solutions.

What are the use-cases?

Introduction


In early March 2019, Intersoft Eurasia team completed work on a test batch of DO-RA gadgets — personal, cross-platform dosimeters-radiometers to monitor the radiation situation at the measurement site, compatible with iOS and Android smartphones and tablets.

By buying such a device, the user receives the following: reliable electronics which have undergone radiation testing in the factory laboratory, stylish colored case in the spirit of Malevich ;) for every taste, gift packaging, color insert instructions in Russian and English, special USB charging cable, a free updateable DO-RA.Pro application from the App Store and Google Play.

The next step in our project implementation is to find the best sales channels for Made in Russia products in the challenging environment of stagnant purchasing power.

(This is the translation of the original article performed by baragol)

We had a bunch of photographs of the main PCB, a YouTube video with drain-voltage waveforms of MOSFETs, a forum post with a breakdown of the capacitance values of LC circuit capacitors and also a number of unboxing videos showing the heating-up of the soldering tip. The only thing that really worried me was the video with the measurement of the peak power consumption during the heating-up. There is nothing in the world more helpless and irresponsible and depraved than burned cartridge newly bought for 60 bucks from Amazon. But let me start from the beginning.

DO-RA: Preparing for Industrial Production

1. Transporting prototypes

The idea of the DO-RA project originated in March 2011 after a nuclear disaster on the Fukushima Daiichi nuclear power plant in Japan. This gadget was conceived as a personal dosimeter/radiometer working with eponymous software (DO-RA.Soft) on mobile platforms (iOS, Android, WP) as well as on desktop platforms—Windows/Linux/MacOS.

At the end of 2017, a tourist from China brought in his backpack ten long-awaited prototypes from the DO-RA.Q test batch. They were manufactured in China based on our design documents and then transported from Shenzhen to Moscow. By the way, the development of design documents was assigned to the largest Design Centre in Eastern Europe—the PROMWAD company. The documents were clear and plain—prepared in IPC format and written in proper English—to enable the automated production of electronic devices in a foreign country.

Indibiome is the new black, following the steps of electric and computer engineering industries, we are foreseeing indibiome design bureaus able to solve unmet needs in healthcare, agriculture, food production, industrial applications.

Indibiome is discussed in my previous paper in Russian (link). Shortly indibiome is indigenous microbiome, like indigenous people, term is used below in the meaning «inherent to the media, localised and optimised for sustainable existence»).

Microbes have always been there, however technologies allowing efficient microbes manipulation and accumulated genetic and experimental data on variety of microbial communities has been on the rise only last decade. Below is my concept of interdisciplinary «indibiome bureau» and you are most welcome to give feedback.

Interview with Rob Vugteveen — an old-school FORTRAN programmer

Reading time5 min
Views2.1K
I decided to make an interview with one of my American friends — Rob Vugteveen. He was working as a FORTRAN programmer back in 1980s, so it's quite a unique experience.


Rob Vugteveen, Carson City, Nevada, USA

K: Hi Rob. I've heard you were working as a Fortran programmer many years ago. Is that right? How the industry was looking back then?

R: Good morning, Kirill.

In the 1980s I made my living as a FORTRAN programmer in the mining industry, primarily in the processing of exploration data and presenting it graphically. We were using VAX minicomputers from Digital Equipment Corporation. This was a time when desktop PCs were growing in popularity, and procedural languages like FORTRAN were being challenged by object-oriented languages. Also, graphics display systems were shifting away from character-cell terminals to X-window-based displays.

FORTRAN (“FORmula TRANslation”) was built for computationally intensive programs, and it did not have its own graphic libraries to display information. There were companies that sold large FORTRAN subroutine libraries to provide that capability. These were not yet designed for the growing popularity of X-window technology.

When we were forced to move from expensive VAX computers to cheaper PCs, we had to write hybrid programs using FORTRAN for computations and C++ for display. It was a bit messy at first. I left that job for something completely different (building a mining museum) and haven’t really done any programming since.

FORTRAN is still used today in scientific research for computationally intensive work, but I’m sure it’s been adapted to work with graphical display systems through external subroutines written in object-oriented code.

Why it is imperative to Invest and Develop a branded Taxi app for your venture?

Reading time3 min
Views1.8K
image

Today’s taxi market is crowded with ride-sharing apps like Uber, Ola, and Lyft. They are giving serious competition for upcoming ventures. These on-demand apps have initiated the radical shift in the taxi industry enabling the smooth transition from conventional taxi hailing to booking a cab through an app. Customers are opting for hailing taxis through the app because of its reliability to get a taxi and ensuring a much better cab booking experience. Thus, the taxi market is ripe for the taking, and this is the right time for entrepreneurs to make use of the opportunity.

Statistics on the Taxi Industry

The traditional taxi industry is still stuck with inefficient phone call bookings, competitors and they stand to lose at least $20 million on an everyday basis just because customers couldn’t find a cab. Another statistics survey tells us that almost 80% of the commuter prefer Ola and Uber over regular taxis and that Uber has completed nearly 2 billion rides since its inception. The profits soared over $20 Billion in the process. What made Uber and Ola successful ventures is the sound business strategy they employed. So if you are going to establish your venture then understanding the market is imperative.

Tech Insights: Are LED filament-lamps so good?

Reading time8 min
Views3.8K
Saluting my LED lamp fans!

Today we will talk about the palpitating and extremely popular subject in recent years — filament LED (Light-Emitted Diode) lamps. Numerous articles have been published here on Habr (1, 2, 3) and on the web, but none of them tells us a word about in-depth analysis of the lamps (what is actually inside) and comparison of their temperature characteristics. Therefore, especially for you — my dear LED-lovers — I conducted a detailed analysis of such lamps from different manufacturers, including temperature measurement of LEDs themselves.

Afterwards we will try to answer the question: are filament lamps as good as marketers present them to us?

Disclaimer: this is my very first attempt to translate and adopt an article from Habr into English, so I will ask you to give a fruitful feedback and correct some mistake if any present.
Shock, thrill and scandals!

Dog Breed Identifier: Full Cycle Development from Keras Program to Android App. on Play Market

Reading time25 min
Views16K
With the recent progress in Neural Networks in general and image Recognition particularly, it might seem that creating an NN-based application for image recognition is a simple routine operation. Well, to some extent it is true: if you can imagine an application of image recognition, then most likely someone have already did something similar. All you need to do is to Google it up and to repeat.

However, there are still countless little details that… they are not insolvable, no. They simply take too much of your time, especially if you are a beginner. What would be of help is a step-by-step project, done right in front of you, start to end. A project that does not contain «this part is obvious so let's skip it» statements. Well, almost :)

In this tutorial we are going to walk through a Dog Breed Identifier: we will create and teach a Neural Network, then we will port it to Java for Android and publish on Google Play.

For those of you who want to see a end result, here is the link to NeuroDog App on Google Play.
