Adding L1/L2 Regularization In PyTorch?

Answer : Following should help for L2 regularization: optimizer = torch.optim.Adam(model.parameters(), lr=1e-4, weight_decay=1e-5) This is presented in the documentation for PyTorch. Have a look at http://pytorch.org/docs/optim.html#torch.optim.Adagrad. You can add L2 loss using the weight decay parameter to the Optimization function. For L2 regularization, l2_lambda = 0.01 l2_reg = torch.tensor(0.) for param in model.parameters(): l2_reg += torch.norm(param) loss += l2_lambda * l2_reg References: https://discuss.pytorch.org/t/how-does-one-implement-weight-regularization-l1-or-l2-manually-without-optimum/7951. http://pytorch.org/docs/master/torch.html?highlight=norm#torch.norm.

Cannot Remove HyperV VEthernet (Default Switch)

Answer : Use the Hyper-V management console or Device Manager aka. devmgmt.msc to remove virtual NIC. Do not remove NIC via registries You remove virtual switch via PowerShell like it's specified here: https://www.starwindsoftware.com/blog/basic-hyper-v-virtual-nic-management Also as a workaround, you can try these steps. https://social.technet.microsoft.com/Forums/windows/en-US/e49df568-4f4c-47b7-b30c-952d1e26ca58/cant-remove-failed-virtual-switch-from-hypervs-virtual-switch-manager

Java Script Array Leng Code Example

Example: array length javascript var numbers = [ 1 , 2 , 3 , 4 , 5 ] ; var length = numbers . length ; for ( var i = 0 ; i < length ; i ++ ) { numbers [ i ] *= 2 ; } // numbers is now [2, 4, 6, 8, 10]

Can A Figcaption Be Restricted To The Width Of A Responsively Sized Image?

Answer : Old question, but I came across the same issue and was able to come up with a fairly neat solution, inspired by this. HTML: <figure> <img src="http://www.placehold.it/300x150" alt="" /> <figcaption>Make me as long as you like</figcaption> </figure>​ CSS: figure { background-color: #fff; padding: 5px; font-size: .875em; display: table; } figure img { display: block; width: 100%; } figcaption { display: table-caption; caption-side: bottom; background: #fff; padding: 0 5px 5px; }​ This ensures the figcaption does not exceed the width of the figure , whilst allowing you to keep max-width on the image. Works in all good browsers and IE8+. There's a Firefox bug that prevents max-width working within elements that are set to display: table . So, instead of using max-width on the image, setting its width to 100% means this works cross-browser. The figure's width will

BLE Scan Is Not Working When Screen Is Off On Android 8.1.0

Answer : As of Android 8.1, unfiltered bluetooth scans are blocked when the screen is turned off. While it is surprising for such a dramatic change to be made in a minor release of Android, this is certainly an intended change based on the comments in the commit: Stop unfiltered BLE scans when the screen goes off. The workaround is to use a ScanFilter with all scans. The new 8.1 operating system code simply verifies that any scans active when the screen is off have at least one scan filter. If those conditions are met the scan results are delivered as in Android 8.0.x and earlier. In order to set up such a scan, you must use the APIs introduced in Android 5.0 and create a ScanFilter with each scan. Below is a filter that will find manufacturer advertisements for any device from Apple with manufacturer ID 0x004c (this will include iBeacons): ScanFilter.Builder builder = new ScanFilter.Builder(); builder.setManufacturerData(0x004c, new byte[] {}); ScanFilter filter = buil

Maximum Value Of Long Java Code Example

Example 1: long max value java Long . MAX_VALUE == 9 _223_372_036_854_775_807L // (9223372036854775807) Long . MIN_VALUE == - 9 _223_372_036_854_775_808L // (-9223372036854775808) Example 2: max long value java /** * A simple application that looks up the value of Long.MAX_VALUE and outputs it to the user. **/ public class Test { public static void main ( String [ ] args ) { System . out . println ( "The maximum Long value is: " + Long . MAX_VALUE ) ; } }

Can MySQL Replace Multiple Characters?

Answer : You can chain REPLACE functions: select replace(replace('hello world','world','earth'),'hello','hi') This will print hi earth . You can even use subqueries to replace multiple strings! select replace(london_english,'hello','hi') as warwickshire_english from ( select replace('hello world','world','earth') as london_english ) sub Or use a JOIN to replace them: select group_concat(newword separator ' ') from ( select 'hello' as oldword union all select 'world' ) orig inner join ( select 'hello' as oldword, 'hi' as newword union all select 'world', 'earth' ) trans on orig.oldword = trans.oldword I'll leave translation using common table expressions as an exercise for the reader ;) Cascading is the only simple and straight-forward solution to mysql for multiple character replacement.

Animating Max-height With CSS Transitions

Answer : Fix delay solution: Put cubic-bezier(0, 1, 0, 1) transition function for element. scss .text { overflow: hidden; max-height: 0; transition: max-height 0.5s cubic-bezier(0, 1, 0, 1); &.full { max-height: 1000px; transition: max-height 1s ease-in-out; } } css .text { overflow: hidden; max-height: 0; transition: max-height 0.5s cubic-bezier(0, 1, 0, 1); } .text.full { max-height: 1000px; transition: max-height 1s ease-in-out; } This is an old question but I just worked out a way to do it and wanted to stick it somewhere so I know where to find it should I need it again :o) So I needed an accordion with clickable "sectionHeading" divs that reveal/hide corresponding "sectionContent" divs. The section content divs have variable heights, which creates a problem as you can't animate height to 100%. I've seen other answers suggesting animating max-height instead but this means sometimes you get delays when th
