It depends only on the direction of the vectors. This indicates that cosine similarity is independent of the magnitude or the size of the vectors. Note that the cosine similarity in case (b) is 1 (similar) though the size of the blue jet ski vector is higher than the orange one. 1 indicates the items are the same whereas -1 represents the compared items are dissimilar. Now to determine if Case(b) and Case(c) are similar to Case(a), we can apply cosine similarity to other two cases,Ĭosine similarity ranges from -1 to 1. So, for case (a) in the figure, cosine similarity is,Ĭosine similarity = cos(blue jet ski, orange jet ski) = cos(30°) = 0.866 Now, to get the cosine similarity between the jet skis in the north-east dimensions, we need to find the cosine of the angle between these two vectors. Image inspired from here: Cosine similarity - Mastering Machine Learning with Spark 2.x The jet ski position is represented by numerical values in both north and east direction and the position of the jet skis can be represented as vectors from the origin. That means, there are two features here (two-dimensional space): North and East. Let’s say that both of the jet skis are riding in the north-east direction. To understand the fundamentals, let us look into the example of two jet skis riding in a lake. We understand that this metric calculates and quantifies the similarity between two items, but how? Let us focus on the most commonly used similarity metric - “Cosine similarity”. There are many similarity metrics used in recommendation systems. The list of items with high similarity values to the ones that the user selected are recommended as “You may also like”. The recommendation system in its core algorithm uses a fundamental mathematical metric called “similarity”, which compares and quantifies the similarity between two items: user selected vs rest of items in the catalog. For example, recommending products in e-commerce sites to recommending movies in movie streaming platforms or recommending a book to borrow from a public library based on your current or previous preferences.Īlgorithms that are used to provide the list of suggestions are called recommendation systems or engines. However, cosine similarity assumes that the two input vectors are not zero-vectors, so it makes sense to me to throw an exception when it happens.Īs 200_success advised, you can omit the entire exception-throwing code and just proceed to division by zero: that will return a special NaN value ("Not a Number").Machine learning algorithms provide customized suggestions in our day-to-day life. Note that sqrt(d_a * d_b) = 0 only when at least one of the input vectors is a zero vector. However, usually a single space is put straight after for: for (int i = 0. Usually people don't put a single space before the semicolon. You can get rid of one call to sqrt double cosine_similarity2(double *A, double *B, unsigned int size) "cosine similarity is not defined whenever one or both " Std::vector::iterator A_iter = A.begin() įor( A_iter != A.end() A_iter++, B_iter++ ) If (A.size() ::iterator B_iter = B.begin() Throw std::logic_error("Vector A and Vector B are not the same size") double cosine_similarity(double *A, double *B, unsigned int size)ĭouble cosine_similarity_vectors(std::vector A, std::vectorB) Use the pointers rather than indexing them. Since the code is already passing pointers The the most efficient way to write the function is to use direct addressing rather than indirect addressing. This is less readable and maintainable than putting the initialization on separate lines: double mul = 0.0 ĭirect Addressing Versus Indirect Addressing Item 1 and 2Ībove belong in the std::logic_error class, item 3 belongs in the Two of the classes are std::runtime_error and std::logic_error.

The cars belong to three categories both on the basis of their countries and performance class. The vehicles in Wreckfest are based on real-life vehicles with each vehicle clear hints on which vehicle they are based on. There are also championships in these Career disciplines which are a collection of races and your end result is determined on your points earned in all of the races. Banger Races are races on regular tracks while the Destruction Derby Races are held on special tracks which encourage destruction such as Figure of Eight tracks and more. You have the normal Banger Races and Destruction Derby events. There are different types of races in the Career mode. What could go wrong with that? The Career mode is divided into different categories which start from the basics and leads you all the way to the World Class racing events. Jump directly in the Career mode and the first race you get to play is a demolition derby event with RWD lawnmowers. The starting menu is a classic throwback to the older versions where you would normally see a banger car sitting in a junk pile. With that out of the way, let’s begin with the review. If you prefer racing in suits and following pace cars after someone touches your side mirror, this game is not for you.

I was lucky enough to nab a key early for this review and we find out whether Wreckfest is really a successor to the Flatout franchise. It might not carry the name Flatout, however, the important question is does it carry the same DNA and spirit of the original titles that made this franchise so successful in the first place? Bugbear calls it the spiritual successor of Flatout so that means it has big shoes to fill. Wreckfest is the latest title by Bugbear Entertainment in the long-running Flatout franchise.

I am using a 4 TB SSD for the music, and an HDPLEX power supply powers the server. My music server is a Raspberry Pi 4 running PiCorePlayer OS and Logitech Media Server. I have arrived at an inflection point in cost, effort, and sound quality, at least for me! Likewise, I have spent far too much money chasing this. I have chased my tail in circles for multiple years. Oh, Where to begin? I have iterated a dozen times around what you are talking about. The most important thing for me is sound quality improvement. UI/software shouldn't be an issue as I use Roon. Currently I'm deciding between Sonore opticalRendu and Lumin U1 mini. I'm thinking about adding a steamer to my audio chain (PC connecting to DAC via USB). It would be great if someone actually compared U1 mini with opticalRendu SQ wise. I value sound quality most because this is the whole point of getting a separate streamer. I don't think I will use Lumin app much even though I decide to get a U1 mini. For myself, I am considering CXN v2 as my "backup" transport since I have an external Benchmark DAC. My thinking is that Spotify Connect vendors (such as Lumin and Bluesound) will certainly support it first. One consideration is Spotify HiFi whenever it arrives and whether it can be supported in the open source world. U1-Mini at 3 times the cost did not sound any better to me. Finally, I did find that I missed having a local display as well as some minimal local controls.Īs for sound quality, I am now back to my Rpi4/Allo DigiOneSignature setup and enjoying it as I have from the beginning. My LAN is quite simple and other apps never ever has this discovery issue. It crashes occasionally when dealing with UPnP server, but the most frustrating thing was its inability to discover its own device consistently and reliably. My Lumin U1-Mini is presently on Ebay after 4 months of use. I just realized opticalRendu might get you even more little boxes LOL. Price wise they are pretty close if you consider buying extra boxes for opticalRendu (Sonore LPSU, Sonore opticalModule, etc). That's why I only care about SQ between the two. I agree with you that the extra software features of Lumin won't matter if only being used as a Roon endpoint. My understanding is that with the proper power supply, the OpticalRendu is a very capable streamer.ĭon't know much about the Lumin so can't comment on that but my guess is that the Auralic and the Lumin have a high price tag because of the software and since I am on Roon I am not sure I need any of that.įrom what I read opticalRendu should be a natural upgrade for you. I was between a DCS Bridge and the Auralic Aries G2.1 streamer, then started leaning more towards the OpticalRendu. I am thinking to consolidate because now I have 6 little boxes and a mishmash of cables (UltraRendu + LPS1.2 + 2x Media Converters + 2x power supplies for the media converters). I have an ethernet-fiber-ethernet media converters to cut the noise flowing thru the network running thru the UltraRendu. I had a PC connected to my DAC (USB) for years, then took the PC away from the Hi-Fi rack and replaced it with an UltraRendu with high quality power supply which is again connected to the DAC via USB (for DSD this works just fine). I will be eager to read the replies to this one.

You can link your existing Samsung Cloud account with OneDrive and your existing photos and videos will be transferred to OneDrive and deleted from your Samsung Cloud account. Samsung suggests that you use Microsoft OneDrive as a replacement for Samsung Cloud. Just to be ultra clear this is happening in April 2021 so if you’re using Samsung Cloud to backup your photos and videos you need to do something about this now! What do I need to do? Even those using Samsung’s premium storage subscriptions will have their subscriptions cancelled and all their photos and videos will be deleted. This means your photos and videos will no longer sync and any that are already on Samsung Cloud will be deleted. You can link your existing Samsung Cloud account with OneDrive and your. In fact most of Samsung Cloud’s features are being removed. Samsung suggests that you use Microsoft OneDrive as a replacement for Samsung Cloud. However, Samsung has been making some changes to Samsung Cloud which means as of April 2021, Samsung Cloud will no longer automatically backup your photos and videos. Thanks to Alex for reminding me that the topic is still pending.For Samsung users, historically you’ve probably used Samsung Cloud to backup your phone. I got some feedback, that also larger uploads could trigger Onedrive account locks. According to this article about Samsung Gallery and OneDrive, I am afraid that Samsung Cloud is not feasible to connect with Work or school account at the moment. From your description, you would like to use Samsung Cloud connect to your OneDrive for business with your Work or school account. And there are cases, where the OneDrive accounts are locked, after users has uploaded huge amount of data – the scenario, that is typical for syncing with OneDrive to upload photos obtained from the Samsung cloud. Thank you for posting your question in this community. Will you write a new Samsung-related article about this issue?įirst, no, I have not heard of this new problem, but that means nothing. The reason for my mail is the following questions: It also has made it straightforward for users to transfer data from Samsung Cloud to OneDrive. I currently have no problem in this regard, since I have not yet started the synchronization. It recommends: Samsung Cloud storage moving to Microsoft OneDrive. Thanks to social networks, various "critical images" are circulating that automatically reach smartphones and other devices via Messenger. The problem may not be the user's photos, but various cartoons in Fotoart (I'll call it that now). It could be that many clouds are blocked in Onedrive because the AI strikes. The first announcements came three or four months ago. In this regard, a NEW problem is looming for a great many people: Onedrive is taking over Samsung's cloud. It happened several times in the past that Onedrive customers had their accounts blocked because of revealing photos or naked babies. I read with interest your article about Onedrive problems of customers. emailed me the day before yesterday, reminding me of the very scenario that is stuck here in the blog and briefly outlined above. Then the content is lost – and there is no defined procedure to get back control. Problem is, Microsoft scans the OneDrive content, and locks out users without a warning, if a violation of its terms of service (TOS) is detected or assumed. I had addressed it within the article mentioned above, that users have the option to move to Microsoft's OneDrive to store it's photos, but should first read my article Microsoft's account suspensions and the OneDrive 'nude' photos. The crux with the OneDrive account lockouts On June 30, 2021, Samsung will delete the data that was stored in the Samsung Cloud. As of April 2021, the features can no longer be used and OneDrive migration support ended. Users who have a premium storage subscription plan with Samsung will have it automatically canceled, and there will be a refund of the overpaid fees, if applicable. However, there is the option to migrate to OneDrive or download the own data. New users will no longer be able to book the features in question since October 2020. While your data will still be safe and available for download until June 2021, Samsung is urging users to make a switch. Services like Gallery Sync and Drive Storage for My Files app by Samsung Cloud will no longer be supported. With my last phone, a Samsung, I got 100GB of free space on OneDrive valid. The company is simply going away with the Gallery Sync and Drive storage features on Samsung smartphones. Starting today, Samsung Cloud is officially shutting down and making a switch to Microsoft’s OneDrive cloud storage. OneDrive for Business is cloud-based file storage available to our students. I had reported it in August 2020 in the German article Samsung Cloud verwirft Premium-Speicher, setzt auf OneDrive ( Samsung Cloud discards premium storage, relies on OneDrive). So, we’ve listed down a couple of things you need to keep in mind before doing so. While running a wifi speed test, it is important to consider certain things. Key Things to Consider in Wifi Speed Test Why? It helps in getting a fair idea of the approximate network speed of your connection. So, see to it that you run multiple network tests without fail. However, these tests may not necessarily give an accurate result. In simple terms, it mimics everybody’s online activities in a controlled setup by downloading sample files and recording speeds. Internet speed test is an effective way to measure the maximum speed- how fast are you able to download and upload data- by accessing nearby test servers. There are several ways to test the wifi speed, some of which include the following: *All prices are exclusive of taxes.Īre you wondering if the speed of your internet connection is up to the mark or not?
