海外TECH	DEV Community	JavaScript Splice Method Explained in Detail	https://dev.to/mavensingh/javascript-splice-method-explained-in-detail-3mmf	JavaScript Splice Method Explained in DetailJavaScript has multiple methods for string and array data type most of them are useful So today We are going to learn about one of them which is splice The given definition for splice method is that it updates modifies the existing array and returns a part of the array which is cut from the original array as per given values to splice method Most of us just use the splice method to cut only the required part from the array but you can do a lot more than just cutting a part of an array That s what we are going to explore in this article We are going to start from the beginning of the splice what splice method is what are the possible ways to use a splice method over an array What is Splice Splice is a method which can be used to update or modify an array also the part which is being cut or updated will be returned as array from splice method and splice method only works for arrays the splice method is not made for string data type so never try to use a splice method on string you ll get only errors nothing else Let s cover all the possible ways to use the splice method on an array Passing single argumentSplice method takes multiple arguments but starting two are important and the first one is the most important the first argument of the splice method tells splice to cut down the array from that index to the last index the starting index is included which means if we have an array and we pass splice index then from index to the last index all values will be deleted from our original array and splice method will return those values as new array below is the code for the following scenario one more thing you can cut the array from right to left as well by providing negative index value in the first argument of splice method Passing Positive Indexbelow is the example for this arr arg arr splice console log original array arr console log array returned by splice arg Passing Negative IndexBelow is the example for this arr arg arr splice console log original array arr console log array returned by splice arg The splice method always cuts or updates the array from left to right even if the given arguments are negative this is the important thing always need to remember as a JavaScript Developer Passing two argumentsWe learned in the previous block that what the first argument does in the splice method now let s understand the second argument what it does and what are the possible ways to use the second argument of the splice method Second argument of the splice method is for the items you want to delete or cut from the array For example we have an array and you want to cut the only two index from this array if it s not middle indexes then it s good you can use single argument in splice method but you want to be cut or removed from array then you might have to use second argument which will tell splice method that our job is done return back the data syntax arr splice It ll cut two indexes from original array and return us the into new array Below is the some use cases of passing two arguments Passing Positive Argumentarr arg arr splice console log original array arr console log array returned by splice arg Passing First Negative argumentarr arg arr splice console log original array arr console log array returned by splice arg If you provide second argument or nil then you ll get no changes in array and as well no return value If your array length is and you provide in the first argument in second you provide something then you ll only cut the last index from the array it ll not give any error regarding second argument passing length or something etc Below is the example for this case Second argument zeroarr arg arr splice console log original array arr console log array returned by splice arg exceeding array length argumentsrr arg arr splice console log original array arr console log array returned by splice arg Passing three or more argumentsNow we have idea of two arguments what each one of them do let s learn about three or more the possible things you can do with three or more arguments are like you can add new indexes in array update the index values delete the index values how we can do these all of things let s see below is the example code for all of these mentioned ways Syntax of three arguments of splice arr splice startIndex elementsToDelete replacewith… Add Values In ArraySo for adding the values into array without updating any value using splice method is very easy what we have to do is that first we need to add our index from where we want to start adding values then for second argument we need to provide which means we don t want to update any value just add them from the given index and move others already in same position to right side which makes array length to increase automatically Below is the code example of this arr arg arr splice console log original array arr console log array returned by splice arg Update Values In ArrayWe have seen how we can add new values in an array using splice the only difference is that if you need to update your array values then you ll need to provide the second value as a valid number zero will not work Below is the example code for updating array using splice method arr arg arr splice console log original array arr console log array returned by splice arg Updating and Deleting at the same timeYes you can update and delete values at the same time as well using splice let s see how for example you have an array and you want update index values and wants to remove index value then you ll need to pass your second argument higher than your updating values like arr splice this will first add those values in same index and once the values are updated will remove index value below is the example for this scenario arr arg arr splice console log original array arr console log array returned by splice arg There are multiple ways you can use the splice method Try some on your own as well if you find this article helpful

海外TECH	DEV Community	My experience starting out with Deepracer (Q4/22)	https://dev.to/niklaswesterstrahle/my-experience-starting-out-with-deepracer-q422-4bjh	My experience starting out with Deepracer Q What is DeepracerI don t think I ll spend too much time writing about the history of deepracer or what it is You can read up on it on AWS website Really short it s gamified reinforcement learning My stepping stone into learning machine learning Why on earth did I start now Or didn t start earlier In short I have to thank a colleague for getting me started He told me his organising an event in our company where we re going to race live on a real track during H Knowit League So I figured it s time to start learning how to do this Earlier I thought this is just too hard saw Jouni Luoma competing ex colleague at prior events in Stockholm Summit and go on competing in Reinvent As I hold him as an experienced AI and Machine learning guru I thought deepracing is beyond me Boy how mistaken I was The only thing I blame Victor for is losing loads of credits running deepracer training And myself for not picking up on this earlier lots of fun So I started learningFirst took a look at the console started training an example model just to see what happens It ll get you driving around the track quite fast But I wanted to do more learn more So some googling followed found some blog posts with code snippets that others had used Copied pasted put some thoughts into what I think of these pieces and how would they help me Tried things like are the wheels pointing towards where the track is going Calculate the difference between the track direction and the heading direction of the car direction diff abs track direction params heading if direction diff gt direction diff direction diff abs heading reward direction diff heading reward abs heading reward heading weight Reward if steering angle is aligned with direction difference abs steering reward abs params steering angle direction diff steering reward abs steering reward steering weightOr if we re on straight more points for going as fast as the car goes Trained a model that does the Reinvent track in about s constantly around the virtual track But now I need to wait to get to try em on a real track Luckily I have access to a track just need to find a space for it and borrow a car I ll write another blog after I have set it up with experiences from that I have since then learned that they re most likely not going to work at all D That real world models are different but more on that later Joining the October Qualifier Open DivisionMy competitive side took over after I got the model done for our internal race and I decided to try my luck in the October Open that Deepracer League runs on AWS Virtual Circuit in the console you can automatically submit your models to race once they ve completed training Watching some YouTube videos of guys talking about hyper parameters and other ways to make your deepracer train better one topic was the idea of a a race line That most of the fastest teams with deepracer seem to follow a race line instead of following the track itself It s like a F car it drives around the track the shortest fastest possible route Deepracer should be able to do this as well even if you just tell it to run as fast as you can get more reward for faster time Given enough time to train it would find that route But to train it a bit faster I went on to learn how to calculate a race line using I started up an Amazon Sagemaker Notebook instance downloaded the GitHub repo and started following the notebook I ran into some errors needed to tweak something a bit But in the end ended up with a nice looking route for our internal race on the track as that s the only one we have as a real track as well as one for the October qualifier For the most part used their reward function as a base honestly not even sure which one I ended up using There was a few additions from other snippets might have worked without as well I tend to doo too many things at once Days of training multiple days I think my model ran for days total in h runs It still drove off track sometimes but resubmitting the model second try did it without driving off track I ended there Ended up which I think is an excellent position sure it s s slower than the winner but these guys have been doing this for years I merely days Of total models submitted I hear people have automation submitting models multiple times for evaluation in races as the same model can drive faster in ideal conditions Next time I ll know to submit a few extra times maybe save a second or few from my time USD laterI kept the AWS bill in my mind and took a look at what running deepracer costs USD hour does rack up costs My aim was to unlock pro league for the next races so I can participate in monthly races that could get me invited to future ReInvents as a participant in that years competitor And that was easily done On the positive side I got some nice SWAG finishing the October open in top so you could say it s an expensive hoodie and a cap Running it cheaper As I can t keep putting USD a month into this hobby I needed to figure how to do this in the future Found out you can even train a model on your laptop or running training on an EC instance Spot or on demand You could even join the dark side and run it on Azure but lets not go there I decided to run training on spot which is actually more annoying than one would think As you can see price per training hour is a lot less And my feeling is that it actually trains faster when I run multiple training sessions parallel You can find more details how to do this at I think I just ran out of time to get it running on spot perfectly Spot instances kept dying and continuing a model from pre existing one seemed to make the model do worse than running from scratch According to some graphs I m still newbie understanding what all the graphs tell me Ended up trying to get a model to converge for the Reinvent Championship track but mostly my model kept just turning right all the time never getting around the track Not sure which parts contributed to that I need to try again for the next races and tracks I don t know how I should analyse logs and what those would tell me I can get some details out of the training I m running but what should it be telling me how should I make my reward function better I m also going to request the use of on demand P instances as I ll rather pay the on demand price than play with dying instances It will still be a fraction of the costs compared to the Deepracer console In case you were not aware to use these type of instances on AWS you will need to request instance quota limit raise from to bigger from AWS and explaining them your use case for running them And those go though an approval process And the request is to be done by region I initially requested us east and later eu north as it s closer to me And can now run I think instances per region on spot for machine learning trainings ReInvent reality of live cars hits meHad the pleasure of attending Reinvent and since there were tracks I tried some of my mostly failing models for the Championship track Just to see them gloriously fail totally stop in the middle of the track and just not move This is just mind blowing what it doesn t work at all like the models in the virtual environment Talked with some of the guys who have been doing this for a longer time got a lot of tips on how one could train a model for the real world applications Next up on my pathIn the end I m like a newborn baby in this reinforcement learning environment Let s see what next year of learning brings I need to go and relearn everything for the physical car see you in on the virtual and live tracks aiming to join Stockholm summit race Analysing training logs better a must learn thing And I think talking of Deepracer a bit some community event meetup Maybe I ll get a few more guys interested in starting to race	2023-01-02 13:19:44
