How To Use Wiki In The Classroom
Learn about PyTorch's features and capabilities. Community. Join the PyTorch developer community to contribute, learn, and get your questions answered. Developer Resources. Find resources and get questions answered. Forums. A place to discuss PyTorch code, issues, install, research. Models (Beta) Discover, publish, and reuse pre-trained models. More and more classrooms are now learning, creating, reading, and testing online. In order to keep up with our technologically demanding lifestyles, the traditional classroom is making way for such innovative tools as wiki. Not only is this an inexpensive way to manage your classroom, it’s also a fun way to engage students in content across the curriculum.

Released under MIT license, built on PyTorch, PyTorch Geometric(PyG) is a python framework for deep learning on irregular structures like graphs, point clouds and manifolds, a.k.a Geometric Deep Learning and contains much relational learning and 3D data processing methods. Graph Neural Network(GNN) is one of the widely used representations learning methods but the implementation of it is quite.

尽管PyTorch Geometric已包含许多有用的数据集,但我们有时候还是需要使用自记录或非公开可用数据创建自己的数据集。自己构建数据集其实是很简单的,你可以通过源码来查看如何构建数据集。也可以通过我们的简单介绍来初步学习自己构建数据集。.

PyG的Data类是最小的数据输入单元,每个样本 (graph)对应一个Data实例,pyg中的batch就是由Data组成。 Data输入的graph应该是COO格式。 例如: graph = Data(x=v_feat, y=label, edge_index=edge_index) 其中x, y, edge_index是必须的,其余属性可以自行指定(如边特征等)。 x指节点特征,y是要预测属性。 edge_index表示边,是一个 [N_e, 2]的整数tensor,每个子列表中的元素是边中对应节点的索引;N_e是边的数量。 这里我们用有机分子乙醇为例构建一个简单的分子图: 1.导入需要的模块.

  1. Wikispaces.com
    Designed specifically for use in the classroom, wikispaces is a social writing platform that also acts as a classroom management tool by keeping teacher and students organized and on task. Not only does this site provide easy to use templates, it’s free and also has a variety of assessment tools. Teachers can also use wikispaces to create assignments and share resources.
  2. axe antiperspirant stickAt its most basic level, this website is free to users. Some of its features include easy to use website templates with unlimited pages, chicken hawk documentary online free and domain name, control over ads, and the chance to earn some money with ads, which can be used for the next class trip.
  3. get guild id discordWith over 300,000 education based workspaces, this wiki-like website offers educators a range of options that encourage student-centered learning. Students can build web sites or web pages that can be shared with other students and staff.

Internally, we just override the collate_fn of the regular PyTorch DataLoader. Here, our collate_fn expects a list of data objects that get merged together. You can just create your own, e.g. , for examples holding a data object and a tensor as a tuple:. bimbo bakeries usa pension benefits center. universal ignition switch with key. navy funeral prayer. To implement dataloaders on a custom dataset we need to override the following two subclass functions: The _len_ () function: returns the size of the dataset. The _getitem_ () function: returns a sample of the given index from the dataset. Python3. import torch. from torch.utils.data import Dataset.

  1. Set Clear Expectations
    Before setting wiki guidelines and sharing them with your students, consult your school’s policies on social media. Provide students with written guidelines that must be adhered to. Let students know that if they publish inappropriate content, there will be consequences. Asking students to sign a contract is also an option.
  2. Start Small
    Take baby steps. Everyone will benefit from gradually increasing wiki use in the classroom. By starting small, teacher’s can stay on top of monitoring classroom wiki, thus remaining in control.
  3. Ask for Help
    Although wiki is fairly easy to use, there are times when you’ll run into stumbling blocks. Ask for help when you don’t understand something. You’d be surprised at much your students and colleagues might know about wiki.
  4. Read other Wikis
    As a class and individually, explore other classroom wikis. This will give you ideas and inspirations for your own wiki pages.
  5. Let Wiki Work for You
    Wiki is more than just a learning tool for students; it’s a communication tool for teachers. Use wiki to keep parents informed and post assignments and other class related content. Your wiki page is easily edited and updated so there’s no more need for a last minute trip to the copy machine.
  6. School-wide Wikis
    Use wikis to showcase field trips, class events and school-wide events, such as the prom or last week’s football game.
  7. Pinterest
    This site has a wealth of information on wiki for the classroom. Simply type in a search term such as "wiki tips for the classroom".  If you don’t already have a Pinterest account, learn more about it through shade perennials safe for dogs.
  8. Collaborate
    Do lots and lots of group work. Create assignments that require students to work together, continuously communicating as part of team as they would in the real world.  For example, a media class can work in teams to create an advertisement for a product of their choice that involves print and/or video.  For a science class, have students work together as a research team investigating the sudden drop in the local wolf population.

  1. Historical Figures
    Instead of just another boring academic paper on an historical figure, make research and documentation fun by creating wiki fan pages. Students can add and edit text, post photos and famous quotes, as well as links to the references they used.
  2. Student as Editor
    Turn grammar into a challenging and competitive game. Have students use wiki to edit text with grammatical errors. Teachers can put students into groups and those with the most edits wins.  Individual edits can also be counted.
  3. Join the Debate Team
    Using a written set of guidelines, teachers post topics that students can argue by using wiki online forums. Teachers will monitor the discussions/debates while students learn online debate etiquette.
  4. Create a Collaborative Story
    Start with one sentence pulled from a hat, “The girl looked beyond the dusty field and saw a team of horses approaching, their riders hands tied behind their backs.” From here, students add and edit text to create a story. Set a minimum amount of words each student must submit. Chances are, you’ll actually have to set a maximum amount of words.
  5. Poetry Class
    For English class, the teacher can post a poem online and have the students discuss its meaning.  Students can also post their own poems for peer review.
  6. Book and Film Reviews
    Students can use wiki to write assigned book and film reviews. Other students can add to as well as comment and discuss the reviews on a monitored forum.
  7. Word Problems
    For math class, teachers can post word problems on wiki. Students work individually or in groups to solve the problems.
  8. Wiki Worlds
    For history and social studies, students can create pages for historical events such as famous battles or specific periods in history, creating entire worlds based on historical facts.
  9. Geography
    Wiki pages can be used to study geography by giving states or countries their own wiki page. Have students include useful and unique information about each geographical area.
  10. Fact Checking
    The reason why wikis is often blacklisted as a reputable source is because not everyone who contributes to a wiki page is an expert. Keep your students on their toes by assigning them to fact check each other’s work.
  11. Riddles
    Encourage teamwork by posting riddles and having groups of students solve them through online collaboration. The students will use a forum to discuss what the possible answer is.
  12. Group Assessments and Tests
    As an alternative way to administer assessments, consider using wiki group assessments.  Students work together, helping one another to achieve success.

WeightedRandomSampler in PyTorch_Geometric Dataloader. Jop_Verbeek (Jop Verbeek) April 25, 2021, 2:16pm #1. Hello everyone, I am writing a program to perform graph classification using PyTorch Geometric, however I have a very imbalanced dataset. I was wondering if I can easily implement a method like WeightedRandomSampler in normal PyTorch?.
