音频信号的情感识别 这是使用OpenSmile,主成分分析和Scikit-learn库中的分类器从Surrey视听表达情感(SAVEE)数据库中的音频信号进行情感识别的一组灵感。 SAVEE数据库是由萨里大学(University of Surrey)的四名以英语为母语的男性说话者(分别为DC,JE,JK,KL),研究生和研究人员记录的,该数据库包括7种不同情绪的录音和480种英国英语发音。 OpenSmile用于从.wav文件中提取特征,它会生成1582个特征。 之后,我将PCA(主成分分析)用于减少三维。 最后,我使用了不同的算法进行分类。 不同的情感是: Anger Disgust Fear Happiness Sadness Surprise Neutral 结果 算法 模型表现 多层感知器分类器 0.8020833333333334 Logistic回归+ lbfgs解算器

Book Description Scratch is a fun, free, beginner-friendly programming environment where you connect blocks of code to build programs. While most famously used to introduce kids to programming, Scratch can make computer science approachable for people of any age. Rather than type countless lines of code in a cryptic programming language, why not use colorful command blocks and cartoon sprites to create powerful scripts? In Learn to Program with Scratch, author Majed Marji uses Scratch to explain the concepts essential to solving real-world programming problems. The labeled, color-coded blocks plainly show each logical step in a given script, and with a single click, you can even test any part of your script to check your logic. You’ll learn how to: Harness the power of repeat loops and recursion Use if/else statements and logical operators to make decisions Store data in variables and lists to use later in your program Read, store, and manipulate user input Implement key computer science algorithms like a linear search and bubble sort Hands-on projects will challenge you to create an Ohm’s law simulator, draw intricate patterns, program sprites to mimic line-following robots, create arcade-style games, and more! Each chapter is packed with detailed explanations, annotated illustrations, guided examples, lots of color, and plenty of exercises to help the lessons stick. Learn to Program with Scratch is the perfect place to start your computer science journey, painlessly. Table of Contents Chapter 1. Getting Started Chapter 2. Motion and Drawing Chapter 3. Looks and Sound Chapter 4. Procedures Chapter 5. Variables Chapter 6. Making Decisions Chapter 7. Repetition: Definite and Indefinite Loops Chapter 8. String Processing Chapter 9.
