Model Development Pipeline The Open R1 pipeline follows a three-stage training strategy, closely aligned with the official DeepSeek-R1 methodology: Knowledge Distillation: A 35K-sample validation trajectory set is extracted from DeepSeek-R1 and used to construct the Mixture-of-Tohughts collection. A...

Understanding Prototypes in JavaScript When we create a class using a constructor function, memory pre-allocates an object caled the prototype object. The constructor function has a prototype property pointing to this object, and the prototype object has a constructor property pointing back to the c...
In Qt, each interaction between a user and a widget is considered an event, such as clicking a button or closing a window. These events emit signals, like a button-click signal or a window-close signal. Widgets in Qt can receive multiple signals and respond with specific actions, known as slots, whi...
1 Reference Concepts 1.0 Fundamentals References must be initialized to a varible upon declaration. References can only bind to variables, not expressions or constants. 1.1 Variable References int a = 0; int& ref = a; // ref is of type int& ref becomes an alias for a; operations on ref direc...
Maximum Substring Frequency Problem Statement: Given a string s, determine the maximum frequency of any substring that satisfies the following constraints: The number of unique characters in the substring must not exceed maxLetters. The length of the substring must be between minSize and maxSize (in...
Understanding Exceptions During program execution, various errors can occur. Some stem from code bugs that require fixing, while others result from invalid user input and can be handled through input validation. Additionally, unpredictable runtime issues like network failures or file access problems...
While studying the ORB-SLAM3 source code, I recreated and refactored its camera model implementation. A key discovery was that despite both pinhole and fisheye cameras having distortion parameters, the fisheye model cannot use cv::undistort for correction. After visualizing the depth-normalized plan...
Architecture and Node Planning A distributed Apache DolphinScheduler setup relies on decoupled Master, Worker, and API server components. The following hostnames and roles will be used throughout this guide: 192.168.30.141 s141 (Master) 192.168.30.142 s142 (Master) 192.168.30.143 s143 (API Server) 1...
