1. stacking machine learning

https://machinelearningmastery.com/stacking-ensemble-machine-learning-with-python/#:~:text=Stacked%20Generalization%20or%20%E2%80%9CStacking%E2%80%9D%20for,dataset%2C%20like%20bagging%20and%20boosting.

2. data scrubbing happens before data being written into SSD

3. lazy learning-

Lazy learning methods simply store the data and generalizing beyond these data is postponed until an explicit request is made. … Eager learning methods use the same approximation to the target function, which must be learned based on training examples and before input queries are observed.

variance and bias — A model that exhibits small variance and high bias will underfit the target, while a model with high variance and little bias will overfit the target. A model with high variance may represent the data set accurately but could lead to overfitting to noisy or otherwise unrepresentative training data.

4. Scikit-learn, TensorFlow, Pytorch difference

5. bagging and boosting

好久沒有寫中文了,長長的文字那種,最近因為覺得復古也是種另類的新奇,於是就回來寫了。

2020 一些人離場,一些人又出場。其實也已進入到無感的狀態,也許那種無感來自於理解人性的多重又複雜,太難的東西別碰,於是就放手觀看這些潮起潮落。珍惜當下,為什麼呢?也許當頓悟自己許多的幸運後,也決定不跟那些奇怪的煩惱糾結,還能夠自由自在地跑跳,健康地呼吸,被一些人支持,並同時支持一些人,其實已經很不錯了。極盡所能將每一天活得富足,僅此而已。

曾經活得目的導向,現在卻追求在每個過程活得極致有趣。而給自己最大的禮物卻是:已慢慢脫離老是羨慕他人生活的幼稚,而有能力對經營自己的人生一往情深。當他離去已久之後,那種懊悔的情緒也慢慢停歇了,唯一欠缺的是那種復燃的執著與熱情。

那樣的熱情充滿火花但也隱藏灼熱的痛苦。這樣的平淡有些無聊,可是卻是練習更敏銳的感受的開始。漸漸可以分出這兩者的差異,前者充滿了能量,炫目而可愛,但可能失去品嚐細節的機會,因為那樣高強度的刺激使人欲罷不能,從而導致對於比較微弱的訊號的遲滯。

開始體驗一些相對微弱的訊號後,很多事情開始有趣了起來。怎麼說呢,開始感受到自己可以體察到一些之前無法體察的事情,人的想法,人的表情,人的動機,人的追求,人的受傷,這些都是人人人人的東西。怎麼有趣呢,因為他總是在流動,而且充滿了各式各樣有趣的能量。

好啦講到這裡,白話文的意思是無聊的日常也可能是種練習,就開始練習體察一些比較微弱的訊息,並且在這過程中反覆的反思並歸納就可以得到一些有趣的發現。

生活即是實驗場!

Procedural Programming — Cobal Fortran (a programming paradigm that uses linear or top-down approach)

Object-Oriented Programming — Python (a programming paradigm that modularizes codes)

Class —A blueprint has (attributes = variables) and does(methods = functions); examples: import

Object (instance) — examples created by the class
