Nurturing Knowledge Learning and Sharing Culture

本文探讨了在知识经济时代终身学习的重要性,指出了人们在学习态度上的误区,并提出了改善学习效率的方法,如建立正确的学习态度和利用团队工作坊促进知识分享。

We are living in a so called knowledge economy age. The change rate of knowledge has been largely accelerated. As a modern people, continually taking in new knowledge is probably a must to build your relative advantage in the talent market. Therefore study is so important. But the question is does everybody know the importance of study and is everybody’s study effective. From my own working and study experience, as well as my observation to others, I often saw there is a large amount of improvement potential in our daily study.

 

The most fundamental question is why we study even after we have spent decades in schools and universities. Some people think they have got enough knowledge to stand in the society firmly in their past lives; so when they meet unsuccessful situation, the only thing they blame is they are so unlucky, there is no any reflection on their own capability. Sometimes, even they identify they probably are incapable for something; they also think it is just because the condition they live or work in is not as good as it should be. So many excuses can forgive themselves. However the opposite is often true. They can improve their own capability so that they can make greater achievement through study, through learning something really helpful and useful. The knowledge studied in school just gave us basic knowledge or just gave us an ability to conduct self-learning which should be lasting for our rest of life.

 

The previous paragraph deals with the willingness to study. But some people could argue we are not unwilling to study. The difficulty is how to study. Anyway, in modern company environment, we often feel we are too busy to have enough time studying. I have ever met a team member. To be honest, he is diligent and wants to accomplish assignment as quickly as possible. I often detected an interesting phenomenon of his hasty behavior. He often used “time is tight and task is heavy” as an excuse to explain why he can not calm down and do due study to help him solve technical problems. For this kind of people, I think letting them realize correct study attitude and what kinds of books can really be helpful is the first step to persuade them to pay due attention to study. Only after he realizes what he can get from study, can he really calm down to study.

 

Team workshop is a quite good method to encourage knowledge sharing and to encourage new knowledge study. In the past years, I always tried to organize regular team workshop to let each team member preside a workshop session per a week in rotation. Team member can choose any topic he/she likes to talk in his/her session. Through workshop, all team members quickly get used to sharing knowledge and are no longer shy to seek help from others when he/she thinks it’s needed. All those formal and informal knowledge sharing activities help team building, help a team becomes a real team.

先看效果: https://pan.quark.cn/s/7baef05d1d08 在信息技术范畴内,语音识别是一项核心的技术,它赋予计算机或设备解析和处理人类语音输入的能力。 本研究项目运用了MFCC(Mel Frequency Cepstral Coefficients)与VQ(Vector Quantization)算法,借助VC++6.0的MFC(Microsoft Foundation Classes)库,开发出一个图形用户界面(GUI),从而达成基础的语音识别功能。 接下来将具体分析这些技术及其应用。 **MFCC特征提取**MFCC是语音信号处理中的一个标准方法,用于将复杂的语音波形转换成一组便于处理的数据参数。 MFCC模拟人类听觉系统对声音频率的感知模式,通过梅尔滤波器组对声音频谱进行分段处理,进而计算每个滤波器组的倒谱系数。 该过程包含以下环节:1. **预加重**:旨在削弱人声的低频响应部分,同时增强高频成分的强度。 2. **分帧和窗函数**:将语音信号分割成多个短时帧,并应用窗函数以降低帧与帧之间的相互干扰。 3. **梅尔尺度滤波**:采用梅尔滤波器组对每一帧进行剖析,获取梅尔频率谱。 4. **取对数**:鉴于人耳对声音强度的感知呈现非线性特征,因此对梅尔频率谱取对数操作以更好地符合人类听觉系统。 5. **离散余弦变换(DCT)**:对对数谱实施DCT运算,提取主要特征,通常选取前12-20个系数作为MFCC特征。 6. **动态特性**:为了捕捉语音的时域变化特征,还可计算MFCC特征的差分值和二阶差分值。 **VQ识别算法**VQ是一种数据压缩方法,在语音识别领域中常用于特征矢量的量化处理。 其基本理念是将高维度的MFCC特征向量映射到一个小型、预...
