The following is the data that you can add to your input file (as an example). Notice that the first line is going to be a line representing your own hobbies. In my case, it is the Vitaly,table tennis,chess,hacking line. Your goal is to create a class called Student. Every Student will contain a name (String) and an ArrayList<String> storing hobbies. Then, you will add all those students from the file into an ArrayList<Student>, with each Student having a separate name and ArrayList of hobbies. Here is an example file containing students (the first line will always represent yourself). NOTE: eventually, we will have a different file containing all our real names and hobbies so that we could find out with how many people each of us share the same hobby. Vitaly,table tennis,chess,hacking Sean,cooking,guitar,rainbow six Nolan,gym,piano,reading,video games Jack,cooking,swimming,music Ray,piano,video games,volleyball Emily,crochet,drawing,gardening,tuba,violin Hudson,anime,video games,trumpet Matt,piano,Reading,video games,traveling Alex,swimming,video games,saxophone Roman,piano,dancing,art Teddy,chess,lifting,swimming Sarah,baking,reading,singing,theatre Maya,violin,knitting,reading,billiards Amy,art,gaming,guitar,table tennis Daniel,video games,tennis,soccer,biking,trumpet Derek,cooking,flute,gaming,swimming,table tennis Daisey,video games,guitar,cleaning,drawing,animated shows,reading,shopping Lily,flute,ocarina,video games,baking Stella,roller skating,sudoku,watching baseball,harp Sophie,viola,ukulele,piano,video games Step 2. Sort the student list in the ascending order of student names and print them all on the screen After reading the file and storing the data in an ArrayList<Student>, your program should sort the ArrayList<Student> in alphabetical order based on their names and then print the students' data (please see an example below). As you can see, here is the list of all students printed in alphabetical order based on their names and hobbies. You are not going to have yourself printed in this list (as you can see, this list does not have Vitaly). Alex: [swimming, video games, saxophone] Amy: [art, gaming, guitar] Daisey: [video games, guitar, cleaning, drawing, animated shows, reading, shopping] Daniel: [video games, tennis, soccer, biking, trumpet] Derek: [cooking, flute, gaming, swimming] Emily: [crochet, drawing, gardening, tuba, violin] Hudson: [anime, video games, trumpet] Jack: [cooking, swimming, music] Lily: [flute, ocarina, video games, baking] Matt: [piano, Reading, video games, traveling] Maya: [violin, knitting, reading, billiards] Nolan: [gym, piano, reading, video games] Ray: [piano, video games, volleyball] Roman: [piano, dancing, art] Sarah: [baking, reading, singing, theatre] Sean: [cooking, guitar, rainbow six] Sophie: [viola, ukulele, piano, video games] Stella: [roller skating, sudoku, watching baseball, harp] Teddy: [chess, lifting, swimming] Step 3. Find all students who share the same hobby with you and print them all on the screen Finally, your program should print the information related to the students who share the same hobby as you. In my case, it would be the following based on the above-mentioned file. There are 0 students sharing the same hobby called "hacking" with me. There are 1 students (Teddy) sharing the same hobby called "chess" with me. There are 2 students (Amy, Derek) sharing the same hobby called "table tennis" with me.

You have been recently looking at a lot of contemporary art and have decided to use your MATLAB knowledge to establish your own artistic credentials. You decide to create your own prints titled untethered and shapes using MATLAB and the plot, plot3, rectangle, and patch commands. You should produce near replicas of the two figures shown below. untethered is driven by the following parametric set of equations evaluated for 5000 regularlyspaced points for 0≤t≤10π

2023-05-29 上传
For the "untethered" figure, you can use the following code: ``` t = linspace(0, 10*pi, 5000); x = sin(t).*(exp(cos(t))-2*cos(4*t)-sin(t/12).^5); y = cos(t).*(exp(cos(t))-2*cos(4*t)-sin(t/12).^5); ...

帮我润色论文。In this paper, we propose a balancing training method to address problems in imbalanced data learning. To this end, we derive a new loss used in the balancing training phase that alleviates the influence of samples that cause an overfitted decision boundary. The proposed loss efficiently improves the performance of any type of imbalance learning methods. In experiments on multiple benchmark data sets, we demonstrate the validity of our method and reveal that the proposed loss outperforms the state-of-the-art cost-sensitive loss methods. Furthermore, since our loss is not restricted to a specific task, model, or training method, it can be easily used in combination with other recent resampling, meta-learning, and cost-sensitive learning methods for class-imbalance problems. Our code is made available at https://github.com/pseulki/IB-Loss.
