New year’s resolutions — 善用okr制定新年目标

假期结束,开工在即,今年开始我将给自己定一些细致的、可度量的全年目标,希望在年底检验的时候能够发现自己取得了不错的成绩。那么今天我就给大家讲讲如何使用OKR来管理自己的目标。

20150806@Tencent 数学建模分享

来这个team之后被安排到做数据挖掘,最近也在折腾推荐系统,不是简单的做个算法,更多的其实对我的挑战是学习hadoop,编写mapreduce。

因为之前参加过两次数学建模竞赛,空隙中做了一次关于数学建模的分享,自己其实也有很多不足的地方,不过接触更多工程后,理解更深刻,更能体会掌握一些数学模型后对解决实际问题时找到突破口是非常有帮助的。

下面是我本次分享的ppt:

主要有对数学模型的一个概览;

了解一次建模过程;

对目前常见的推荐系统方法的一个介绍;

对item cf的一个实现;

对latent factor算法的一个介绍;

以及比较好用的降维方法(pca)的介绍。

我要更努力

可能比起很多已经接触开发很久的人,比起那些计算机学院的人,我的优势不多。

他们起点比我高,所以我要更努力。

他们所学的基础课比我多,所以我要努力地去弥补这些东西,

我一直在尝试创业,想做一些不一样的东西,想把我的想法实现,所以我来尝试做技术,抓紧时间多学一点。

我不会示弱,因为我会更努力。

 

4 seasons in a year

I wanna be there with you when the season comes and goes
We’re taking a trip to see the world’ It’s going going on
Car’ train’ or ship’ even by airplane
We make a plan and fantasize it every sunday

Oh it’ so nice in spring time We’re just relaxing outside
Flowers all around us’ like we’re in the world of fantasy
When the summer comes’ We are having a Barbeque
Waiting for night time’ so I get to see the fireworks with you
When the fall comes’ all the leaves’ll turn gold
When the winter comes’ now everything is covered by the snow

Every single season’ It seems so brand new
When I can spend it with you

All the memories of the good days’ they never fade away
We’ve been through ups and downs ever since the first day
Sometimes we argue and fuss
But every single day is a blessing for the two of us
Oh This is where I’m supposed to be cuz you got a hold on me
The feelings gets stronger everytime you look at me
And I gotta say that you’re the one I need
Remember the day I made a promise to you right by the sea

Uh So many nights’ I made you cry
You still stayed right by my side
Give me a sign when you’re feeling down so I can treat you right
Cuz we used to cry together til the break of dawn
Every word you said to me still keeps me going strong so

We’ve been through the good times
and we’ve been through the bad times
Let me show you how I feel
Here are my words of honesty
No matter where you are’ no matter where you go
I know I got to be with you so

Let me know’ the things you wanna see in spring time
Let me know’ the things you wanna see in summer time
When the flowers bloom’ when the sun shines bright
I wanna be with you
I gotta be with you
Let me know’ the things you wanna see in fall time
Let me know’ the things you wanna see in winter time
When the leaves fall’ When the snow is falling down
I wanna be with you
I gotta be with you
So baby talk to me’ baby smile for me
We chill out and time goes by slowly
We just joke around and talk about the stupidest things
And when we get enough of it’ we look for another place

You know I would go anywhere’ just to be by your side
Let’s go out and take a drive under the beautiful sky
We’ve been to a lot of places’ but we still we have to go
You know there’s gotta be so much more

Someday we start a family
I will take you to the place that we used to hang around
The place where we met and the place we belong
The place where we made our promise to love forever
