[SWM] Day3: Repository Tools for SWM(Not only Git)

Repository Tools for SWM

Trello

Trello is a project management tool
Can be used to organise individual project, but especially useful for teams
Basic version is free
Work in process(WIP) limits: Treat the cards like a limited currency – prevents overloading developers

Pros:

  • Free!(at least the basic version)
  • Open to members and non-members
  • Private or Public Boards(limited to a group of members or anyone)
  • Natural user interface, support for agile projects
  • Ease of use, visibility and tracking, collaborative
  • Available on Iphone/Android/Windows
  • Developer API
  • supports Agile feature

Cons:

  • Cards/tasks cannot be assigned to multiple boards/projects
  • No tagging capability
  • Difficult to move/copy etc. multiple cards
  • No due dates per tasks
  • Checklist are not easily visible inside cards
  • Have to pay for the full experience

Managing source code

Using a source code version control or repository system, such as git, SVN(SubVersionN), CVS(Concurrent Versioning system)
Why not just keep copies in backup folders?
Error prone
Hard to roll back
Cannot easily share code with others
Can not do automated testing
enter image description here

Git

  • Git is a (free and open source) distributed version control system
  • Designed originally for command line use
    Git has these concept:
  • Working folder
  • Staging area
  • Local repository
  • Remote repository
    enter image description here
    You work locally, perhaps in a development branch, and when happy add and commit changes to a local repository
    When you are REALLY happy, you can push changes to a remote server, storing a ‘master’ version of the software

Centralized(single user)

Draw how you imagine a simple workflow would look?
enter image description here
- Just a master branch
- Single user
- This is very like how you would use SVN,CVS
- No danger of conflicts as only 1 user

Centralized(multiple users)

enter image description here
  • User check out code and work independently
  • So inevitably one person will update the origin master first
  • The second person will need to update their code from the origin and manage their changes to avoid conflicts

Continuous integration

enter image description here
Once linked to the repository, testing can for example be automatically activated every time someone commits, or every night
  • Produce a visible report of test results
  • Makes sure the system is buildable(compilable)
  • List code coverage
  • Style violation
  • Static analysis

Gitlab CI

GitLab has a built in CI
You submit a script on your repository which the CI server runs
- a bit like the build scripts we looked at last week
GitLab using YAML
- Commit a special file called .gitlab-ci.yml in your project root
- Composed of jobs of work, rules about when they should be run, and scripts of commands
- Set up runners in GitLab CI to action the jobs in the script

Use of Git

[MLE] W2 Multivariate linear regression

Multivariate linear regression What we have talked about in week 1 is linear regression with single feature. For example, in the house pricing predicting problem, we only use the size of house (x) to predict the price (y) . But what if there are other features like age, bedroom numbers and so on? Linear regression with multiple variables is also known as “multivariate linear regression” According to the graph above, we now have new representation symbols: n = number of features m = number of training examples \(x^{(i)}\) = \(i^{th}\) training example \(x^{(i)}_j\) = feature j in \(i^{th}\) training example 1416 is \(x_{1}^{(2)}\) in this case, m is 47 for example, n is 4. Hypothesis function The multivariable form of the hypothesis function accommodating these multiple features is as follows: if we make \(x_0\) to 1, the \(h_{\theta}(x)\) will be \(\theta^Tx\), which is \(\theta\) transpose matrix multiply by x, where \(\theta\) is a vector of 1 by(n+1) dimension an

[MLE] W1 Introduction

Before get started The blog is based on the machine learning course on Coursera, taught by Andrew Ng . From today, i will begin my study trip on Machine learning, which will be labelled as MLE. This course will last 11 weeks and today is week 1. The application of machine learning is everywhere: Database mining Applications can’t program by hand Self-customizing program Understanding human learning(brain, real AI) Introduction What is Machine Learning Two definitions of machine learning are offered: Arthur Samuel described it as: “the field of study that gives computers the ability to learn without being explicitly programmed.” This is an older, informal definition. Tom Mitchell provides a more modern definition: “A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measured by P, improves with experience E.” If we raise a example of what is machine learning: If

[AIM] MetaHeuristics

Day2 Outline Metaheuristics -definition Single point based search method(simple stochastic local search) Iterated local search Scheduling Tabu Search Metaheuristic what is a metaheuristic? A metaheuristic is a high-level problem independent algorithmic framework that provides a set of guidelines or strategies to develop heuristic optimization algorithms. what is the difference between heuristic and metaheuristic? Heuristic : Heuristics are problem-dependent techniques. As such, they usually are adapted to the problem at hand and they try to take full advantage of the particularities of this problem. However, because they are often too greedy, they usually get trapped in a local optimum and thus fail, in general, to obtain the global optimum solution. Metaheuristic : Meta-heuristics, on the other hand, are problem-independent techniques . As such, they do not take advantage of any specificity of the problem and, therefore, can be used as black boxes . In general, t
