例如:多次實驗結果其平均值接近於已知的數據真值(理論值),可知道數據「準確」,或是數據具有「高準確度」;反之,平均值與已知的數據真值差距較大,表示實驗數據不準確,或準確度不高。 精密則是當實驗數據很精準時,會要求實驗有高度的再現性,表示實驗數據是可信的,也就是實驗數據需要具有高精密度。 (多次量度或計算的結果的一致程度)。 一個結果必須要同時符合準確與精密這兩個條件,才可算是正確無誤。 參見[编辑] 外部鏈接[编辑] Accuracy vs Precision. Accuracy and precision are used in context of measurement. Accuracy refers to the degree of conformity and correctness of something when compared to a true or absolute value, while precision refers to a state of strict exactness — how consistently something is strictly exact. In other words, the precision of an experiment, object, or value is a measure of the reliability of, for example, an experiment.

The accuracy of an experiment, object, or value is a measurement of how closely results agree with a true or accepted value. Both accuracy and precision are terms used in the fields of science, engineering, and statistics. edit Example One can say that a measurement is accurate but not precise, precise but not accurate, or neither or both. Edit Target Comparison Accuracy is the degree of correctness, while precision is how strict that correctness is (or isn't) — how reproducible results are. How precise the shots are depends on how often the arrows land near each other on the target. Accuracy precision - Google 搜尋. Image feature extraction - Google 搜尋. Standardization vs. normalization. If you're new here, you may want to subscribe to my RSS feed.

Thanks for visiting! In the overall knowledge discovery process, before data mining itself, data preprocessing plays a crucial role. One of the first steps concerns the normalization of the data. This step is very important when dealing with parameters of different units and scales. For example, some data mining techniques use the Euclidean distance. Two methods are usually well known for rescaling data. On the other hand, you can use standardization on your data set. Both of these techniques have their drawbacks. So my question is what do you usually use when mining your data and why? Note: Thanks to Benny Raphael for fruitful discussions on this topic.

Used to 過去的習慣,跟 be used to 現在習慣於…的用法與不同 | Jessie's 潔西家. 大家對 used to 跟 be used to 非常的執著,有很多的問題,其實用法不太一樣,大家似乎是被中文影響很大,真的不用太執著於中文,記清楚這兩個用法的不同,把適當的用詞用在適當的時機,不要太鑽牛角尖,還有很多文法點是需要記得,真的弄不清楚,多閱讀一些母語使用著的文章,應該會慢慢理解究竟什麼時候要用什麼的時態,什麼的用法。

下面是新近寫的,改過幾次,希望或許會比較容易理解一點:) I used to get up early. 跟 I’m used to getting up early. 這兩句有什麼差別嗎? 差很大喔。 很多人都弄不清楚的 used to + V1 跟 be used to + V-ing,常被問到的潔西乾脆又寫了一篇。 I used to get up early. I’m used to getting up early. 簡單來說是這樣,但是語言這種東西通常是很難說得懂解釋的清楚的,哈哈,所以最好的方式就是記住用法,不要光去背片語的中文意思,過去習慣於,現在習慣於,這樣其實很容易混淆,最好的方式就是多閱讀一些例子,真正理解後,自己多寫多練習,多看文章裡面怎麼用,熟能生巧 Practice makes perfect. 一. used to + V1 曾經…,從前…,過去經常…,過去習慣於… 主詞 + used to + 動詞原型(潔西自己簡單寫做V1) ,用來表示過去規律發生的事或過去持續一段時間的事,但是現在不這麼做了。 比方說 I used to go to a pub ever weekend. 這個句型是: 主詞+used to + 動詞原型 used 在這裡是 use 的過去式 used to 在這裡是不定詞的 to ,所以後面要加動詞原型 used to 在這裡指的是過去經常性的動作或事實或習慣等,兩個字不可以拆開 這個句型是過去式,所以就是基本過去簡單式一般動詞的句型 1.

主詞 + used to + V1 (動詞原型) I used to swim a lot, but now I don’t swim very often. 我從前常常游泳,但是現在我不常游泳。 We used to live in a small town, but now we live in Taipei. 我們過去住在一個小鎮,但是我們現在住台北。 2. 我從前不喜歡他。 Be used to 用法 - Google 搜尋.

Q:however, nevertheless 和 moreover 之間有何不同呢? - 英文資訊交流網. A:我們可以使用 however 或 nevertheless (或 nonetheless) 這些副詞來使第二句話與第一句話形成對比,即第二件事情與第一件事情或第二個觀念與第一個觀念形成對比。 它們之間的差異僅在於 nevertheless 比 however 更為正式一些且比 however 更具加強語氣的強調作用。 例如: I can understand everything you say about wanting to go on a trip to Japan with Mike. However, I am totally against it. 必須注意的是,在引導兩件事情或兩個觀念之間的對比時,however 和 nevertheless 通常放在句子的開頭,但它們亦可位在句中和句末。 There will be no more pay increases this year. He’s still able to get around quite well. His whole life has been plagued by illness, however. 英文中比 however 和 nevertheless 更為非正式的用語則有 even so, in spite of this, yet 或 yet…still。

Mary’s really quite ill and has been for some time. 至於 moreover,其意為「並且,而且,再者,此外」,與 however 的意思並不相同。 Benjamin is, moreover, a novelist of promise. Even 和 however可以放一起嗎? - Google 搜尋. Background.

(課文句子) Tip A + include + B表「A包含B (B為A的一部份)」 The assignment for this summer vacation will include observing the stars and keeping records of their movement. 這個暑假的作業包含觀察星星,並將其運行軌跡記錄下來。 緊接的動詞observe及keep須為V-ing型態 亦可用include B in A表「將B包含在A中」 You should include your club experiences in your resume. 你應該要將社團經驗納入履歷中。 2. S + V…, including + N He has performed in many charitable events, includinga special show arranged to raise money after the 9-11 terrorist attacks. 3.過去分詞included作形容詞使用時須作後位修飾,即置於所修飾的名詞之後。

S + V…, N + included Several students in our class have the flu, myself included (=including myself.) 班上很多同學都感冒了,也包括我。 Tip including + N或N + included均表「包括」之意,兩者常可互換使用。 文章來源:活用 English4U deserve + V-ing用法中,該V-ing用字須能代表主詞的「被動」含意,方才正確。
