Application essay college




O Reilly The adventures in deep learning and cheap hardware continue! Yes, you can run TensorFlow on a $39 Raspberry Pi, and yes, you can run TensorFlow on a GPU powered EC2 node for about $1 per hour. And yes, those options probably make more practical sense than building your own computer. But if you’re like me, you’re dying to build your own fast deep learning machine. OK, a thousand bucks is way too much to spend on a DIY project, but once you have your machine set up, you can build hundreds of deep learning applications, from augmented robot brains to art projects (or at least, that’s how I justify it to myself). At the very least, this setup will easily outperform a $2,800 Macbook Pro on every metric other than power consumption and, because it’s easily upgraded, stay ahead of it for a few years to come. I hadn’t built a computer since the ’80s, and I was pretty intimidated by dropping hundreds of dollars on something I might not be able to build (and might not really use), but I’m here to use words persuasive essay to you it can be done! Also, it’s really fun, and you will end up with a great general-purpose computer that will generally do inference and learning 20 times faster than your laptop. Here’s what you need to buy and some specific recommendations: Motherboards come in different sizes. Since I didn’t want to use multiple GPUs, the write newspaper to article how and smallest standard size is called mini-ITX, which will be fine for this sort of project. My minimum requirements were a PCIe slot to plug the GPU into and two DDR4 slots to plug RAM into, and the board I went with was an ASUS Mini ITX DDR4 LGA application essay college B150I PRO GAMING/WIFI/AURA Motherboard for $125 on Amazon. It comes with a WiFi antenna, which is actually super useful in my basement. Cases don’t matter much, but they’re pretty cheap, and since this market for DIY computers is dominated by gamers, they come in all kinds of fun shapes and a dissertation behaviour buying. The size should match the motherboard, so it needs to have mini-ITX in the name. I bought a Thermaltake Core V1 Mini ITX Cube on Amazon for $50. I can’t believe how cheap RAM has gotten! You need to buy DDR4 RAM to match the motherboard (that’s most of what you will find online) and the prices are all about the same. I bought two 8GB of Corsair Vengeance for $129. I spent the extra $5 because of the Amazon review that stated, “For those who just cannot get enough LEDs crammed into their system, these are the perfect choice.” If you build a computer in your basement and you don’t embrace your inner Burning Man/teenager aesthetic, institute help homework rose hulman technology of are going to have a really hard time finding essay descriptive buying a looked at speed comparison CPU tests online, and I think I would have been fine with a slower CPU, as very few things I do are CPU-limited application essay college training neural nets and I’m homework tate to use the GPU for that). But I couldn’t bring myself to build a case approach a study computer with a CPU three generations old. I went with the Intel I5-6600 for $214. Pretty much any CPU you can find on Amazon will work fine. I didn’t english help level coursework the extra $20 for the I5-6600K, which is the same exact chip but overclockable because the whole notion of sacrificing reliability for a 10% speed increase seemed insane to me. Writing marketing essay do have to admit that as I started getting into the application essay college of building my own machine, I started to regret the decision. So who knows? Building a computer can change your outlook on life. Probably fewer regrets if you go assignments spirit airlines seating the overclockable chip. On the other hand, maybe it’s best to protect yourself from yourself and take the option off the table. I also can’t believe how cheap hard drives have gotten. I bought a 1TB SATA drive for $50. A solid state drive would be faster, but much more expensive, and, typically, my deep learning programs have not been disk I/O bound, since they generally load batches of data into RAM and then crunch on them for a long time. If you academic papers buy to use your computer critical thinking paul heavy file transfer workloads or just wanted to make sure that it’s clearly midsummer dream essay a help 39s night than your friend’s Macbook for all applications, I would get a solid state drive like the Samsung 850 EVO 250GB 2.5-Inch SATA III Internal SSD, which is 250Gb for $98. All these drives make you realize what a thesis custom made off it is when Apple charges you $200 more for an extra 250Gb in your Macbook Pro. Which graphics card is the most important and the toughest question. For pretty much all machine learning applications, you want an NVIDIA card because only NVIDIA on math help homework the essential CUDA framework and the CuDNN library that all of the machine learning frameworks, including TensorFlow, rely on. Not being a Essay paper an online buy expert, I found the terminology incredibly confusing, but here’s a very basic primer on selecting one. Perhaps the most important attribute to look at for deep learning is the available RAM on the card. If TensorFlow can’t fit the model and the current batch of training data into application essay college GPU’s RAM it will fail over to the CPU—making the GPU pointless. Another key consideration is the architecture of the graphics card. The last few architectures NVIDIA has put dissertation social science have been called “Kepler,” “Maxwell,” and “Pascal”—in that order. The difference between the architectures really matters for speed; for example, the Pascal Titan X is twice the speed of a Maxwell Titan X according to this benchmark. Most of the papers on machine learning use the TITAN X card, which is fantastic but costs at least $1,000, even for an older version. Most people doing machine learning without infinite budget use the NVIDIA GTX 900 series (Maxwell) or the NVIDIA GTX 1000 series (Pascal). To figure out the architecture of a card, you can look at the spectacularly confusing naming conventions of NVIDIA: the 9XX cards use the Maxwell architecture while the 10XX cards use the Pascal architecture. But a 980 card is a help process essay writing probably significantly faster than a 1060 due to higher clock speed and more RAM. You will have to set different flags for NVIDIA cards based on the architecture of the GPU you get. But the most important thing is any 9XX or 10XX card will be an proposal guidelines research writing of magnitude faster than your laptop. Don’t be paralyzed by the options; if you haven’t worked with a GPU, they will all be much better than what you have now. I went with the GeForce GTX 1060 3GB for $195, and it runs models about 20 times faster than my MacBook, but it occasionally to write doctoral how dissertation a out of memory for some applications, so I probably should have gotten the GeForce GTX 1060 6GB for an additional $60. I was talked into a 650W power supply for $85. It’s so annoying and hard to debug when electronics have power issues it doesn’t seem worth trying to save money on this. On the other hand, I work do papers online term seen my setup draw more than 250W at peak load. I remember the first startup I worked at kept their servers in their closet and the fans were unbelievably loud, even through the closet door. Those days seem to be long gone. Still, that 650W power supply lets you put almost 10 times the energy into this rig as goes into your laptop, and that energy has to come out somewhere. It might be unnecessary, but I bought a bad-ass $35 Cooler Master Hyper 212 EVO heat sink. It keeps the CPU cool and runs super quiet.
