海外TECH	DEV Community	Neural Networks Explained in 40 Seconds	https://dev.to/jsstackdevelopers/neural-networks-explained-in-40-seconds-3oj4	Neural Networks Explained in SecondsVery Deep Neural Networks Explained in Seconds Very deep neural networks VDNN illustrated with data animation a second video featuring supervised learning layers neurons fuzzy classification and convolution filters It is said that a picture is worth a thousand words Here instead I use a video to illustrate the concept of very deep neural networks VDNN I use a supervised classification problem to explain how a VDNN works Supervised classification is one of the main algorithms in supervised learning The training set has four groups each assigned a different color The type of DNN described here is a convolutional neural network CNN it relies on filtering techniques The filter is referred to in the literature as a convolution operator thus the name CNN PurposeThe purpose is to classify any new or future data point outside the training set In practice not the whole training set is used to build the classifier but a subset called test set to check performance against the control set and fine tune parameters The control set consists of the training set points not in the test set This type of design is called cross validation The classifier illustrated in the video eventually classifies any new point outside the training set instantly In addition this article also illustrates the concepts of fractal or fuzzy classification and machine learning performed in GPU graphics processing unit DescriptionThe methodology consists of three steps Step Transforming the test set into a format suitable as input for the DNN This may involve rescaling or some mapping frequently a logistic mapping applied to the original data In our case the bivariate data was binned and transformed into pixel locations to fit into the video frames The first frame of the video represents the test set after the initial mapping Step The transition between a frame and the next one until no unclassified black pixels are left is as follows You apply a local filter to each pixel to assign its color the group it is assigned to using a majority vote among neighboring pixels In this example the filter is non linear It is similar to a high pass filter or image enhancing filter typically used in signal processing Linear filters are known as averaging or blurring filters and of no use here Each frame in the video represents a layer of the DNN It is called a very deep neural network because it involves a large number of layers hundreds in this example Step The frame obtained once no black pixels are left in the middle of the video is the output of the DNN To classify any future point compute its pixel location on the image using the mapping in step and find which color it is assigned to The illustration below is a Gif image and was obtained by converting my MP video into Gif format I used the online EZGif converter to produce it The original video can be viewed on YouTube here Each pixel is called a neuron in DNN terminology and just like in the human brain interacts only with neighboring neurons in a given layer Thus the name neural network GPU Machine LearningSince all the machine learning apparatus is performed on images using standard filtering techniques once the original data set is converted to an image it is easy to run the algorithm in video memory In other words getting it done in the GPU the graphics processing unit I mention it to explain and illustrate what GPU machine learning means to people unfamiliar with this technology Fuzzy or Fractal ClassificationOnce no black unclassified pixels are left the classifier has accomplished its task However in my video I added extra frames to illustrate the concept of fractal classification The border between clusters is somewhat porous or fuzzy A point close to the border may be assigned to any of the two or three adjacent groups at the border The extra frames called layers in DNN terminology shows the shifting border over time It allows you to compute the probability that a point next to the border belongs to one group or another by looking at its shifting class assignments over time I will describe this in more details in an upcoming article ConclusionIn this article I explained in layman s terms the concepts of deep neural network DNN convolutional neural network CNN convolution filter layers and neuron of a neural network GPU machine learning and fuzzy classification The video illustration uses an unusually large number of layers video frames with each neuron pixel connected to very few other nearby neurons the neighboring pixels Thus the use of the term very deep neural network or VDNN In my example I use only one connection per neuron It leads to a quite granular classifier and offers a few benefits In practice though traditional DNN s use much fewer layers but neurons are connected to dozens or hundreds of other neurons In other words the local filter uses a much larger window The methodology is described in details in my new book available here To not miss future updates sign up to our newsletter here In an upcoming article I will show an application to unsupervised learning with a post processing filter playing the role of the sigmoid mapping in a DNN	2022-03-27 23:31:59
海外TECH	DEV Community	One Month of Coffee Chats in Review: Frequently Asked Questions	https://dev.to/bascodes/one-month-of-coffee-chats-in-review-frequently-asked-questions-2nje	One Month of Coffee Chats in Review Frequently Asked QuestionsI am doing coffee chats for a month now Here are some of the questions I received most frequently Can you hear me Yes At which type of companies should I apply to as a junior From a developer s point of view there are two types of companies Those that uses technology and those that produces technology These companies know exactly how technology works They also understand your way Ideally they also support newcomers and promote them further Technology is the DNA of such companies they are passionate about technology Therefore they look for such passion in their employees as well They know that there is often much more value in hiring someone who knows how to learn rather than someone who supposedly already knows everything The other companies that only use technology are primarily looking for service providers who solve their problems immediately It is often the case that such companies also fill junior positions but this is often only done for cost reasons not necessarily out of the motivation to follow a common path with the employee Of course there are exceptions in both cases and the above should only be considered a rule of thumb So you should look for companies that already mention training opportunities and open culture in the job advertisement Examples of technology first companies Google Facebook Microsoft Amazon Airbnb Todoist …Examples of technology second companies Walmart Starbucks General Motors … What are companies looking for when hiring a candidate Even more than being a good programmer it is crucial to understand the employer s business problems that they want to solve with technology What does that mean Creative solutions in the software world often come from a developer understanding the problem and then looking for a suitable solution rather than blindly working through given tickets of small tasks Of course it is important to be a good programmer but beyond that you should also be a good consultant If you are the one who builds bridges between the business world and the software world all doors are open to you What is your background I learned to program as a kid on my parent s computer which was Pentium MHz at that time in Basic In school I learned some Logo C and Pascal I got my first client after school and after a year or two doing freelancing work as a teenager I decided to take the next step One of my clients sponsored my university studies I ve been working as a consultant ever since I like to see different teams different problems and different technological approaches in new projects It s the variety that appeals to me Should I learn programming languages other than JavaScript In general Yes absolutely In particular Maybe not yet When you feel reasonably confident in the programming language you learned first it is a good idea to learn other programming languages Many programming languages are very similar to each other with functional programming languages being an exception For example if you are good at JavaScript it will be easy to learn Python PHP or C The advantage of at least knowing several programming languages is that you get to know different methods for solving the same problems In this way your understanding of good programming style and your repertoire of tools will broaden For a prospective employer it is also essential to see that you are able and willing to learn new topics and technologies I have learned the essential things but I often don t get to the solutions to our assignments Devs What is the secret of putting the blocks together The difficulty in programming is often to break down a problem into such small components that it can be described with the limited commands and constructs of a programming language Especially in the beginning your thoughts may often revolve around the peculiarities of the programming language Do I put a comma or a semicolon Do I have to put a parenthesis here etc Pseudo code can be a helpful way to first decompose the problem close to the natural language and then implement it in the computer language Apart from that it is practice practice and practice that will get you further here Try to understand the solutions of other tasks find the patterns in the solutions try your ideas again and again until it fits You will eventually develop an intuition for how programmes are put together Why did you pick Python as your main language of choice Software development is more than just web development And in many areas Python is one of the most universally applicable languages For example I often deal with scientists who want to turn their ideas into software Because Python has such a simple structure almost like pseudo code it is easy to turn these ideas into reality because the language doesn t get in the way This does not mean that other languages are not suitable JavaScript in particular can be found in many places nowadays In the end it s a matter of personal preference and perhaps also of chance which jobs you end up with Regardless as already explained it is a good idea to master more than one programming language	2022-03-27
