Hi, I am looking into creating a mixture model based on the Generalised Extreme Value distribution (GEV). As opposed to a Gaussian Mixture Model, which is very popular and a Google search can help with most issues, creating a GEV mixture model is proving to be very difficult for me. I am not overly experienced in using Python, any analysis I've done to date was carried out using MATLAB, but for a number of reasons using Python makes more sense for this project. If anyone has any experience creating mixture models or clustering in general (It doesn't have to be GEV) I would really appreciate any advice you may have. The dataset I will be using is time-series data.

Note for mods : I would like to apologize for posting in General Discussion, because I don't know in which category this post would be the most appropriate. I got into engineering college at the beginning of this year (and no I didn't get my gaming laptop with a 1660ti after that, I got this beast over a year ago) and now I have come to the part where in my studies I need to use stuff like octave and soon CAD software as well (like Autodesk EAGLE). And so far I have used only octave and MATLAB. And my computer seems to be struggling with plotting a few surfaces/curves with lots of points. I guess it'd be because of the program using my internal gpu and not the discrete gpu ? but I am dumb, so feel free to correct me. I have a good enough CPU a Ryzen 5 4600H with 16GB of DDR4 RAM (@3200 MHz). I am running Pop OS btw (I am actually dual booting with windows 11). Also, since I am just in my first semester in college, I don't really know what other things (scientific computations and programs) I can use my GPU for. I know I'll learn about it, as I come to use the programs in upcoming semesters. But if anyone knows and could tell me it'd be much appreciated since I'd like to get familiar with the industry standard programs ASAP (My major is Electronics Engg btw). PS : Is there any built in tool in Pop OS that'd allow me to monitor my GPU usage ? because the system monitor doesn't show my GPU usage.

TL;DR version: I am looking for an ultrabook/Macbook for around 900 dollars (pre-tax). I am concerned that I cannot get on-par performance for the same amount of money that I spent on my laptop in 2015. Here are my specific questions, but all ideas and suggestions will be much appreciated. 1- Will there be an M1-like chipset from AMD/Intel that will bring any Windows laptop to M1 Macbook performance levels (within similar packaging/thermal constraints)? 2- Is this an exceptionally bad time to buy a laptop? Should I delay it by a year if possible? 3- What would be a set of specifications for a laptop ready for the next 5 years? Feb 21 Update: Tentatively decided to wait for Macbook Air/Pro with M2. --------------------------------Post starts here. ----------------------------- I am looking for something in the same price range as my previous laptop. However, I won't "upgrade" to a new laptop if I won't get a substantially better device, naturally! I also want to treat this as a practice in exploring how much 'newer and faster technology' has become more accessible over the last 5 years. To establish the baseline, let me quickly go over the specs of my current laptop. In June 2015, I bought the ASUS UX303L-Signature Edition with the following specs for 800 USD (equiv. to 873 in Dec'20 1). 13.3'' 3200 x 1800 with touch Intel Core i5-5200U 8GB DDR3L 1600 MHz 256GB SSD (around 400 MB/s read and write) Intel HD Graphics 5500 1.46 kg My review of the device: It had good(not Macbook level, but satisfactory) battery life. It was an absolute beast for high school. Its construction is rigid. Storage has been fine. Processor has just started feeling sluggish in the last year. Yellows look mustard-y, but it is not bothersome. Great for someone who needs a computer for classes and extracurriculars. Why change it now? The hinge snapped a few times. For now, it's held together by epoxy. Battery life has gone downhill, too. Also, now that I am deep into the college life, I'm doing more engineering work. That means CAD modeling and MATLAB analysis. Also Python. I am sure thousands of people would understand the workload. Novice engineer work. It is getting laggier by day. Note: I don't have a workstation. Looking at the current market Note: I still need to carry this device everywhere and use it on battery power. Loads of typing is inevitable, too. I would love to have a 14'' or 15'' display this time. I also don't have good enough Internet connection for any modern Wi-Fi standard to be an issue. 16:10 aspect ratio is preferred, but 16:9 is acceptable. Also, MacOS is fine (well, except Solidworks, and ARM Bootcamp support will be an interesting question, but I may use university computers for SW.) I'd quit following laptop prices after buying mine, and I am shocked to see how much prices have gone up. I've checked out a few competitors (in the ultrabook category) that sprung to mind, and here's what I can get for the same price in Jan'21: ---------SKIP THIS SECTION IF YOU ARE FAMILIAR WITH CURRENT PRICING ON ULTRABOOKS ---------- DELL: 900 USD OLD XPS 13: i7-10510U , 8GB LPDDR3 2133 MHz , 256 GB PCIe SSD,13'' FHD non-touch 2 1000 USD NEW XPS 13: i3-1115G4, 8GB LPDDR4 4267MHz , 256 GB PCIe SSD,13''FHD non-touch 2 ASUS: 1000 USD ASUS ZenBook Duo UX481: i7-10510U, 8GB LPDDR3 2133 MHz, 512 GB PCIe SSD, 14'' FHD touch3 800 USD ASUS Zenbook UX325JA-XB51: i5-1035G1, 8GB LPDDR4X RAM, 256GB PCIe SSD, 13'' FHD non-touch3 1000 USD ASUS Zenbook UX325JA-DB71: i7-1065G7, 8GB LPDDR4X RAM, 512GB PCIe SSD, 13'' FHD non-touch3 900 USD ASUS Zenbook UX431FL-EH74 : i7-10510U, 8GB RAM, 512GB PCIE SSD, 14'' FHD touch?, NVIDIA GeForce MX2503 ... similar options at similar prices 800 USD Asus Zenbook UM433DA-DH75 : Ryzen 7 3700U, 8GB RAM, 512GB PCIe SSD, 14.0" FHD touch?3 HP: 835 USD HP ENVY x360 15'' BASE: i5-1135G7m 8GB DDR4 RAM, 256 GB Intel(?)

If I sacrifice on battery life/build quality/ thin-and-light aspect, I can get an i7/Ryzen 7, 16 GB of RAM for a bit above my budget. That makes me concerned about how future-proof my new laptop would be. I bought my ultrabook when 12 GB RAM was the absolute maximum on an ultrabook and SSD had just gotten cheaper. It has served me well, but now I need something that will serve me equally well for at least another 5 years. I also have another option- getting my brother's 2016 Macbook Pro (i5-6267U, 256 GB SSD, 8GB DDR3 2133 Mhz, Iris 550) to use for a year. I know benchmarks are not perfect. Especially across operating systems. But here's one comparison list: PassMark (Multi-thread) - CPU i5-5200U : 2,512 (Current) i5-6267U : 3,236 (Loaner Mac) i3-1115G4 : 6,465 i7-10510U : 6,997 i5-1035G7 : 8,414 i7-1065G7: 8,967 i5-1135G7 : 9,774 i7-1165G7 : 10,414 Ryzen 5 4500U : 11,267 Ryzen 7 4700U : 13,802 PassMark shows significant increase in performance. However, I'm not sure what that would mean for me, the workloads I have do not benefit drastically from more cores/threads. I feel that RAM would be a bigger factor, for example. Or maybe I should consider a -weak but still much better than integrated- GPU. Main Question: I feel insulted about waiting 5 years and still getting a laptop with 8GB of RAM. Looking at the rate of development at desktops, I feel terrible about paying so much when a desktop would be 10 times faster, more reliable and future proof. But I need a laptop. I am open to all ideas, all suggestions, all recommendations. Specifically, I also want to ask: 1- Will there be an M1-like chipset from AMD/Intel that will bring any Windows laptop to M1 Macbook performance levels (within similar packaging constraints)? 2- Is this an exceptionally bad time to buy a laptop? Should I delay it by a year? 3- What would be a set of specifications for a laptop ready for the next 5 years?

I need help with this argument in the code which is denoted by "W": https://i.imgur.com/u7uW41n.png https://i.imgur.com/vichQOs.png Q1. What exactly is W doing here? What exactly is it doing to turn a sawtooth wave into a triangular wave? Q2. I see no changes in the rising and falling edges except for the shapes of both edges. The rising edge is going from -1 to 1 and the falling edge is going from 1 to -1. Am I correct to assume that the only real change is in the shapes of the two?

Hello, I have to make a program in Matlab. Write 2 programs that calculate the factorial of a user-entered number between 0 and 20. One should use a for loop and the other should use a while loop as the main logical structure. 1. Prompt the user to enter a number to be factorialized 2. Return an error message if it is less than 0 or greater than 20 3. Compute and display the result If anybody can help me out, that would be great. Not really good at programming/ coding. Thank you.

I am trying to solve a question, which asks you to use RBF interpolation (radial basis functions) to smear an image using matlab. The smear is given by a Gaussian function and is applied along a diagonal line, and use of a Wendland function is also needed to find the original pixel coordinates. Does anyone have any experience in this and would be able to help? I have more info and diagrams I can provide! I also have a coded example of linear RBF interpolation, but I am stuck on how to apply this to an image and create a smear. Any ideas would be most appreciated!

Hey guys, I'm having some trouble calculating feval of a multi variable function because I need to pass values as a vector. Example: I have this function: x1^2 + x1*x2 + 0.5* x2^2 + x1 + 10*x2 (defined everything using syms x1 x2 and converted it using matlabFunction() ) and I have a point x0 = [0; 0] where first value should be x1 and the second one x2 Problem is when I call feval(f, x0), Matlab throws an error saying "Input argument "x2" is undefined." I know it works if I call feval(f, 0, 0) but that is not what I need because my function can have more than 2 dimensions so it needs to somehow know that first vector value corresponds to first variable, second vector value to second variable and etc... Is there a way I can do this?

Hey Guys As a side project to my university degree I have dreamed up this project that I'd absolutely love to bring to fulierision, however, there are aspects of the project that I will need some guidance and probably some help. The project Centres around developing a State space module of the river basis, relating the input (rainfall in the region) to the output (The hight of the river at a particular gauge) see figure1. this can be done Using system identification in Matlab and the likes which I'm well versed in the difficulty I am having is that I don't know where to start in getting the data in a form that is usable, My current plan is to try to develop something that takes the forecasted weather (https://www.met.ie/) from the rainfall forecast map then quantise this using a grid that is approximately the size of the river basin a visual replication is shown in figure 2 (excuse the awful drawing ?) Once that data is gotten in terms of a value that represents the value of the square (part of the research will be determining if mean, median, max, or whatever methods influence on the accuracy of the model ) it can be passed into the model shown in figure 3 once data is gathered for the input and output the matimatimatical can be obtained using some of the Matlab system identification toolboxes my questions to you's that are more experienced programmers than myself are as follows what is the best way to try to strip the data from the met Eireann website https://www.met.ie/ is there a way of getting the data from the webpage itself before it is drawn, or would some image recession be better what languages, libraries etc. should I look into because I don't have the time, experience or, the patients to do it from scratch unless its relatively simple something like this has been done before[1] however they used upstream gauges, so the time frame is much shorter, whereas this approach can directly relate the forecast weather to the river hight thanks for your help in advance people, and if you have any questions or you just find it interesting and want to know more drop me a message or post below thank you [1] https://ieeexplore-ieee-org.jproxy.nuim.ie/document/8064947

I am a second semester engineering student and we I have a course in which I need MatLab on my laptop. My laptop is a Chromebook (I'll leave a link to the model at the end) and I just found out I can't install MatLab on it. Is there any way I could install Windows or Linux on it so that I could install MatLab that way? I think spec wise it should be fine to run it. My Chromebook: https://www.samsung.com/us/computing/chromebooks/12-14/samsung-chromebook-plus-xe521qab-k01us/

So I've been trying to install Logitech Options especially for the past few days and my PC keeps on failing. I downloaded the installation file from the main website, but for some reason whenever I click the installation file, the program just decides to shut itself off before it even bothers to open the pop-up window to install the software. I've tried looking through the roaming data and found zero trace of Logitech, including Program Files and Documents. Does anybody know why I can't install this? The same goes for MatLab as whenever i try to install, it never reaches installation process as it shuts down as well. Thought these two were related somehow. Any way I can fix this? The software works on my laptop just fine, but not desktop. I'm running on Windows 10 64 bit.

I looked around and didn't find a posting of this news topic on your forum so I open one up myself. If there is already a topic/thread here to the same story: my apologies! So a user on reddit found a workaround to uplift/boost the performance of AMD CPUs in applications that use the Intel Math Kernel Library. The problem with lower performance on AMD CPUs has existed for about 10 years and is also known for that long. The cause was that the library checked in the beginning with which Vendor-ID the CPU responded, which resulted for an AMD CPU in the fallback mode for the instruction set to normal SSE. Despite the fact that Ryzen CPUs from AMD and even older CPUs from AMD support other instruction sets like AVX that are much faster. The workaround forces the library to run in AVX2 mode, no matter if the CPU is Intel or not. Performance gains vary from CPU-Gen to CPU-Gen, but in certain scenarios there is an uplift of 250% or more. Zen 2 does gain more than Zen1(+) for example. Hope this is will be covered in techlinked or the wan show...

I am grad student and I work on MATLAB. I am planning to purchase a laptop but wasn't able to decide whether to go with Gaming laptops or workstation laptops. The system i use is a i7-7700, 1050 ti and 32 GB RAM. My programs usually consume 12-18 GB RAM. So If anyone can suggest me a Good but a budget laptop(not more than 2000 dollar). P.S.: Please consider that i do lot of Photoshop so if color accuracy is needed.

Hello, I am a university student who is trying to get a secondary laptop for light use. I already own an Aorus x7 pro-sync for gaming and other hard works, But its dimensions are too big so that I can't carry it around as easily. So I wan't to ask you guys' recommendation for light and small laptop from 11~13 inch with at least 4gb of ram and can run matlab. I am not going to use for other than matlab, internet and the MS office. Thank you! ============================================== I am currently thinking of getting the lenovo yoga 2 11 with intel pentium n3540. Will pentium n3540 enough to run a full matlab?

So here's the dealio: I have 500 of the big ones to build a heavily productivity focoused machine, but is still aable to play games like CSGO and Minecraft comfertabley. The programs being used are like Adobe PS and Premiere and also using a program called "Matlab" or somehing like that. It also should be able to handle Autodesk easily.

Anyone great at matlab. I'm in college and just started the class 3 weeks ago. My teacher is ok but I wanted to see if you guys know of anything I should be learning that is need to know. Thanks.

Hello all, This is my first PC build. I have done very extensive research into the cheapest and most powerful components I can afford, and use. This computer will be used for higher level academia. With that being said, knowing how smart the enthusiast can build their knowledge base, I would like to ask you guys a couple of questions. I am really struggling to decide on a motherboard. Goal: I am building a machine that computes, NOT games. This computer will be used for computing many very large algorithms, at very large iterations, simultaneously, 24/7. What I need: most reliable internet connectivity (high bandwidth preferred, but not needed, reliability> Bandwidth) large CPU bandwidth near absolute reliability (I can't afford the time it takes to run a 1 week algorithm again) highest power efficiency (I really want top tier caps) A board that when used with CUDA, will have no problem linking my CPU and GPU Overall silence from my rig (sometimes I like to sleep) ECC capability I do not care about looks as I am a functionalist. What I plan to build: -Intel Xeon E5-1650 V3 3.5Ghz 6-Core (for ECC capability, and power) -Gigabyte GTX 970 4 GB (for CUDA cores to price ratio and base clock with overhead capability)(~1600 CUDA cores) -Fractal Design XL R2 (Black Pearl) ATX Full Tower Case (for its silence reducing capability, and size) -Crucial 16GB (2x8GB) DDR4 2,133 Mhz RAM ECC -Corsair H100i 77 CFM Liquid CPU Cooler - bequiet! Dark Power Pro 850W (build quality and reliability, and sweet silence (no coil wine)) -5 or 6 HDDs (only 3 at first)( with raid, for reliability) - Samsung SSD 240GB (for OS, and computing program) Motherboards I'm eyeing: ASUS X99-E WS (too expensive, 500 just for a Mobo? Seriously?) ASUS X99 Deluxe (no premium capacitors) GA-X99-UD4P (or any other UD"x"P Board) ASRock X99 Extreme4 Questions: Is 850W too much? (according to ASUS's WAttage calc, I'll be around the 800watt zone.) (GPU 243Watts ^Tom'sHardware guide on gtx 970^, TDP on CPU is 140W ^Intel^ What Motherboard should I use? remember I need stability and reliability, and I am a broke college student (kind of, almost done saving up). Do you notice any compatibility issues, or significant bottlenecks? Will there be any problems with the GPU, and computing for long periods of time, or any errors as a result? For those of you wondering, I will be running Matlabs and Octave. And when I am attending my computer intermittently with python and OpenCl. Thank you gents and ladies for viewing my post! I am really anxious to hear your factual/anecdotal opinion!

I've ended up settling on a GTX 770. The age old question arises... 2GB vs. 4GB? But wait! Don't ask for my screen resolution, don't ask what games I'm going to be playing... Well, because all of that is secondary. I have not been able to find an answer relating my situation... I guess the question is: will 4GB of VRAM offer an advantage vs. 2GB of VRAM for 3D cad, MATLAB/Mathematica/Maple, video editing, and other similar programs? I am not familiar with the VRAM utilization of these programs and I guess that's why I have resorted to asking you! Regards, Bosebeer

Hello guys, Well my question is the difference between Wolfram Language - or Mathematica and Matlab. Does anyone has experience with both ? And which is better and in what prospective you have decided it. I search the internet before coming here but I wasnt able to retrieve much and I got a little bit comfused. Another question ... I am interesting in Electrical Engineering therefore if anyone is an electrical engineering was it difficult to learn matlab ? And also since I have 1 year until the time comes to go to the university I want to get the most of that year therefore is it possible to learn Matlab or Mathematica even if you dont have univeristy level education? Thanks
