ต้องลึกแค่ไหนถึงจะเรียกว่า Deep Learning กันนะ ? 🧐
.
👉 มารู้จักกับ Deep Learning ศาสตร์แห่งการเรียนรู้ที่เลียนแบบการทำงานของสมองมนุษย์ จะเป็นยังไง และมีรายละเอียดยังไง หากพร้อมแล้ว ไปอ่านกันโลดดด !!
.
.
💡 รู้จัก Deep Learning
.
Deep Learning เป็นการเรียนรู้ของเครื่องคอมพิวเตอร์แบบอัตโนมัติ ที่เลียนแบบการทำงานของสมองในมนุษย์ เพื่อทำให้เครื่องสามารถเข้าใจและเรียนรู้จากข้อมูลจำนวนมาก ๆ ได้นั่นเอง ซึ่งเป็นส่วนหนึ่งของ Machine Learning และ Artificial Intelligence (AI) ซึ่งในปัจจุบันมีการนำเทคโนโลยีนี้มาใช้กันอย่างแพร่หลาย เช่น รถยนต์ขับเคลื่อนอัตโนมัติ โดยสามารถจำป้ายต่าง ๆ แยกแยะรถยนต์กับคนเดินบนถนน หรือสิ่งขีดขวางต่าง ๆ ตรวจจับความเร็วของรถคันหน้าได้นั่นเอง ซึ่งโครงสร้างอัลกอริทึมของ Deep Learning จะสร้าง Artificial Neural Network มันสามารถเรียนรู้และตัดสินใจทำสิ่งต่าง ๆ ได้ด้วยตนเอง
.
.
🔧 Deep Learning ทำงานอย่างไร ?
.
Deep Learning จะทำงานเลียนการทำงานของโครงข่ายเซลล์ประสาทของมนุษย์ หรือที่เรียกว่า Neural Networks ซึ่งสามารถคิดซับซ้อนเหมือนมนุษย์ได้ สิ่งเหล่านี้จะเกิดขึ้นไม่ได้เลยหากไม่มีชุดข้อมูล เพื่อสร้างอัลกอริทึมที่สามารถจำแนก ทำนาย และจัดหมวดหมู่ให้กับข้อมูลที่เราต้องการได้นั่นเอง
.
โดย Neural Networks จะมีโหนดที่เชื่อมถึงกันหลาย ๆ ชั้น (เหมือนเส้นประสาทของมนุษย์) จะทำหน้าที่ปรับแต่งประสิทธิภาพของการทำนาย หรือการจัดหมวดหมู่ ยิ่งมีเยอะ และลึกเท่าไหร่ การทำนายก็จะแม่นยำขึ้นเท่านั้น โดยโมเดล Deep Learning จะใช้ชุดข้อมูลจำนวนมากและจะเรียนรู้ลักษณะต่าง ๆ ได้ด้วยตนเองจนกว่าจะได้ผลลัพธ์ที่แม่นยำออกมานั่นเอง
.
ซึ่งในปัจจุบันก็ Deep Learning ก็มีอยู่หลายประเภท ไว้คราวหน้าเดี๋ยวแอดจะมาเล่าให้ฟัง แต่ที่ฮิต ๆ กันก็มีอยู่ 2 ประเภท คือ
.
🔸 Convolutional neural networks (CNNs) - หรือเรียกว่า ConvNets มีเลเยอร์หลายชั้น ส่วนใหญ่จะใช้กับการประมวลผลภาพ สามารถตรวจจับลักษณะภายในรูปภาพได้
.
🔹 Recurrent neural network (RNNs) - ส่วนใหญ่จะใช้ใน Natural Language, Speech Recognition, หรือข้อมูลที่เป็น Time Series เพราะโมเดลสามารถเรียนรู้และจำรูปแบบลำดับของข้อมูลได้นั่นเอง
.
.
✨ Deep Learning ใช้ทำอะไรได้บ้าง ?
.
ในปัจจุบัน Deep Learning จะถูกใช้ในงานต่าง ๆ เช่น Image Recognition, natural language processing (NLP), Speech Recognition Software, Self-driving Cars และอื่น ๆ อีกมากมาย และยังสามารถประยุกต์ใช้ในสาขาอาชีพอื่น ๆ ได้ด้วย ดังนี้
.
🚀 การบิน อวกาศ และการทหาร - ใช้ Deep Learning เพื่อสร้างเครื่องมือในการตรวจจับวัตถุจากดาวเทียม, ระบุตำแหน่งและพื้นที่, รวมถึงการสำรวจพื้นที่ทางทหารเพื่อความปลอดภัยของกองทัพ
.
🏭 ระบบอัตโนมัติในโรงงานอุตสาหกรรม - ใช้ Deep Learning เพื่อปรับปรุงสภาพแวดล้อมในการทำงานเพื่อให้มีความปลอดภัยมากขึ้น เช่น ในโรงงานที่มีเครื่องจักรมากมาย เพิ่มการตรวจจับอัตโนมัติเมื่อพนักงานเข้าใกล้เครื่องจักร หรือจะเป็นการตรวจจับความผิดปกติของเครื่องจักร เพื่อความปลอดภัย เป็นต้น
.
👨🔬 ทางการแพทย์ - ในปัจจุบันมีการใช้ Deep Learning เพื่อทำการวิจัย และวินิจฉัยโรคมะเร็ง จากการตรวจจับเซลล์มะเร็งในร่างกายมนุษย์แบบอัตโนมัติ

time definition 在 Benny Price Fitness Facebook 的最佳貼文
This morning, as I started putting on my shoes to go for a run, my grandfather exclaimed "You've got to teach online in 25minutes!" 😱
"Yeah, I'm just going for a whizz round the block." 😎
"What on earth is the point in that??" 🤨 he responded.
-
I would be less fit if I never went for a run unless I had time to warm up, run 5k and stretch. I would be weaker if I only lifted weights when I had 1.5hrs for a full balls-to-the-wall session 🏋🏻♂️
-
Sure, some people can routinely make time for high intensity, high volume exercise.
Some people love making that the centrepiece of their day.
Some are both and content with fitness being a focal point of their life 👍🏽 but, contrary to what the instagram fitness world will lead you to believe, that's really fucking rare.
-
Way too may of us seem to think the goal is to "get fit". I can almost guarantee it shouldn't be for most. Not by whatever arbitrary definition of it you're using. You just need to get fit-ter 📈
-
A friend of mine the other day said "I can't go to the gym without a PT because if I go on my own I just get in a 60% workout and it's a waste of my time." 🤦🏻♂️
HOW have we been convinced that exercise at 60% is a waste of time? I’ll bet most “waste” more time daily scrolling 📱
-
Side note: If you think a PT's “job” is to run your arse into the ground at 100%, I can almost guarantee you've got a mediocre one 💁🏻♂️
-
Equally, it doesn't have to take a lot of your day ⏱ I consulted a couple the other day who have been "meaning to get fit" for a while. They already had a few machines, but seemed to think 15mins on them 3 times a week was pointless. No. What's pointless is having machines you never use.
-
🙏🏽 Please, just start by doing SOMETHING. Something you enjoy, that doesn't feel unpleasantly or unsustainably intense / difficult, and then do it for as long as is convenient. Once it's a habit, start trying to give it a bit more effort, and making a bit more time for it. I know we say to have goals in fitness and business and life but, for some, maybe it's the goal that has been getting in the way? Maybe it's the goal that's so daunting that you don't do ANYTHING to get yourself closer to it? 🧐

Every time I shop, I shop for my "Capsule Wardrobe", and my definition of that is a wardrobe that is filled with timeless pieces I can wear season after season, be layered in colder temperatures or be worn alone when summer comes around again. That sounds like a simple task, to shop for timeless pieces to be worn over and over again, but the hardest part is to find the QUALITY that can last you that many seasons, wash after wash....

time definition 在 Spice N' Pans Youtube 的精選貼文
You must ditch your instant noodles for this super easy Soy Sauce Chicken Noodles. This recipe is suitable for those of you who are working from home. It's so easy that I believe everyone can make this at home. Some of you ask how did we calculate 15 mins of cooking time as mentioned in our video title. First of all, we need to get our cooking time definition right. Cooking time to is means the time when heat is turned on and applied to the ingredients. All other time is not counted. In this video, Roland cooked the chicken for 8 mins then he turned off the heat. Then he brought the sauce to boil to thicken the sauce. At most this will only take 2 mins. Then he brought a pot of water to boil to blanch vegetables and noodles. Vegetables literally take seconds to cook and noodles take about 2 mins max to cook because we used fresh noodles. Assuming we assign about 1.5 mins to let the water boil then that brings us nicely to about 15 mins of cooking time altogether.
See the ingredient list below for your easy reference.
Hope you can recreate this yummy dish in the comfort of your home. Happy cooking!

But our souls be matching
Nothing is a coincidence
I know I met you for a reason
It was talk, lol, soul connection
Shocked oh no way this is happening
thought I couldn’t fall no more
But you pulled me back up from that hole
You became my new goal
I guess I need to get on birth control

time definition 在 Metrics | YouTube Analytics and Reporting APIs - Google ... 的推薦與評價
This document defines the metrics that you can retrieve using the YouTube Analytics API. This API supports real-time queries to generate custom YouTube Analytics reports.
Metrics are individual measurements of user activity, ad performance, or estimated revenue. User activity metrics include things like video view counts and ratings (likes and dislikes).
Core metricsWhile the YouTube Analytics API is subject to the Deprecation Policy defined in the Terms of Service, non-core metrics (and non-core dimensions) are not subject to the policy. In the definitions on this page, any metric that is a core metric is explicitly identified as such.
The list below identifies the API's core metrics.
annotationClickThroughRate
annotationCloseRate
averageViewDuration

estimatedMinutesWatched
estimatedRevenue
likes
shares
subscribersGained
subscribersLost
viewerPercentage
views
The
earnings
core metric was deprecated on August 4, 2016, and renamed estimatedRevenue
. In keeping with the Deprecation Policy defined in the Terms of Service, the earnings
and estimatedRevenue
metrics were concurrently supported until August 10, 2017.The
favoritesAdded
and favoritesRemoved
core metrics were deprecated on March 31, 2015. These metrics could be retrieved only through the YouTube Analytics API.See the list of YouTube APIs subject to the Deprecation Policy for more information.
View metrics
views (core metric)
This metric represents different numbers in different types of reports:
In video reports, this metric specifies the number of times that a video was viewed.
In playlist reports that do not use the
isCurated
dimension, thismetric specifies the total number of views for videos in the playlist, regardless of whether
those views occurred in the context of the playlist. Note that the metric value includes
only views of the channel owner's videos.
In these reports, the
playlistViews
metric indicates the number of times that playlistvideos were viewed in the context of a specific playlist.
In playlist reports that use the
isCurated
dimension, this metric indicatesthe number of times that videos were viewed in the context of a specific playlist. Note
that the
playlistViews
metric is not supported for these reports.This is a core metric and is subject to the Deprecation Policy.
playlistViews
This metric is defined in the playlist metrics section.
redViews
The number of times that a video was viewed by YouTube Premium (previously known as YouTube Red) members.
uniques (deprecated September 27, 2016)
The number of unique viewers that watched a video. This calculation is based on the number of unique cookies and, therefore, will overcount users who are using multiple devices or browsers.
The
uniques
metric was deprecated on September 27, 2016. It is not a core metric and will be supported until October 31, 2016.viewerPercentage (core metric)
The percentage of viewers who were logged in when watching the video or playlist. This is a core metric and is subject to the Deprecation Policy.
estimatedMinutesWatched (core metric)
The number of minutes that users watched videos for the specified channel, content owner, video, or playlist. This is a core metric and is subject to the Deprecation Policy.
estimatedRedMinutesWatched
The number of minutes that YouTube Premium (previously known as YouTube Red) members watched a video.
averageViewDuration (core metric)
The average length, in seconds, of video playbacks. As of December 13, 2021, this metric excludes looping clips traffic. In a playlist report, the metric indicates the average length, in seconds, of video playbacks that occurred in the context of a playlist. This is a core metric and is subject to the Deprecation Policy.
averageViewPercentage
The average percentage of a video watched during a video playback. As of December 13, 2021, this metric excludes looping clips traffic.
comments (core metric)
The number of times that users commented on a video. See the YouTube Help Center for more information. This is a core metric and is subject to the Deprecation Policy.
likes (core metric)
The number of times that users indicated that they liked a video by giving it a positive rating. This is a core metric and is subject to the Deprecation Policy.
dislikes (core metric)
The number of times that users indicated that they disliked a video by giving it a negative rating. This is a core metric and is subject to the Deprecation Policy.
shares (core metric)
The number of times that users shared a video through the
Share
button. See the YouTube Help Center for more information. This is a core metric and is subject to the Deprecation Policy.subscribersGained (core metric)
The number of times that users subscribed to a channel. This is a core metric and is subject to the Deprecation Policy.
Channels can gain or lose subscribers in several places, including the video watch page, the channel page, and the guide that appears on the YouTube home page.
In channel reports, this metric includes subscribers gained from any of these places. However, in reports that use either the
video
dimension or the filter
parameter to restrict the response to only include data for a particular video, the subscribersGained
metric will only include statistics from the specified video's watch page.subscribersLost (core metric)
The number of times that users unsubscribed from a channel. This is a core metric and is subject to the Deprecation Policy.
Data for this metric is reported similarly to the
subscribersGained
metric.In channel reports, this metric includes subscribers lost through any mechanism through which users can unsubcribe from a channel. However, in reports that use either the
video
dimension or the filter
parameter to restrict the response to only include data for a particular video, this metric only includes users who unsubscribed from the specified video's watch page.videosAddedToPlaylists
The number of times that videos were added to any YouTube playlists. The videos could have been added to the video owner's playlist or to other channels' playlists.
The metric value does include the number of times that videos were added to default playlists like the "Watch Later" playlist. However, it does not count playlists that a video is automatically added to, such as a channel's uploads playlist or a user's watch history.
This metric returns an absolute number, meaning that if a user adds a video to a playlist, removes it, and then adds it again, the metric value reflects the video being added to a playlist twice. Data for this metric is not available for dates before October 1, 2014.
videosRemovedFromPlaylists
The number of times that videos were removed from any YouTube playlists. The videos could have been removed from the video owner's playlist or from other channels' playlists.
The metric value includes the number of times that videos were removed from default playlists like the "Watch Later" playlist.
This metric returns an absolute number, meaning that if a user adds a video to a playlist, removes it, adds it again, and then removes it again, the metric value reflects the video being removed from a playlist twice. Data for this metric is not available for dates before October 1, 2014.
Deprecated engagement metrics
The following metrics were both core metrics that were deprecated on March 31, 2015.
favoritesAdded (core metric) (deprecated March 31, 2015)
The number of times that users marked a video as a favorite video. See the YouTube Help Center for more information. This is a core metric and is subject to the Deprecation Policy.
favoritesRemoved (core metric) (deprecated March 31, 2015)
The number of times that users removed a video from their favorite video lists. See the YouTube Help Center for more information. This is a core metric and is subject to the Deprecation Policy.
Playlist reports contain two types of metrics that explain how viewers interact with the videos
in a playlist:
Aggregated video metrics provide user activity and impression metrics that are
aggregated for all videos in the playlist that are also owned by the channel that owns the
playlist. Metrics for videos owned by other channels are not computed in the aggregation. As a
result, if a channel creates a playlist that contains only videos owned by other channels,
reports for those playlists will not provide values for these metrics.
Refer to the view metrics and
watch time metrics sections of this document for definitions
of supported aggregated video metrics.
In-playlist metrics reflect user activity and engagement in the context of the
playlist page. These metrics include views for all videos in the playlist, regardless of which
channel owns them, but only counts views that occurred in the playlist context.
Most of the metrics listed below are in-playlist metrics; the remaining metrics in the list, such
as the playlistSaves
metric, are about user interactions with the playlist itself and
not with videos in the playlist. As such, those metrics would not be characterized as either
aggregated video metrics or in-playlist metrics.
The estimated average amount of time, in minutes, that a viewer viewed videos in a playlist
after the playlist was initiated. Note that this metric includes only playlist views that
occurred on the web.
playlistAverageViewDuration
The estimated average length, in seconds, watched per playlist view. Note that this metric
represents the average length of views of individual videos within a playlist; the
averageTimeInPlaylist
metric, by contrast, represents the average timeeach viewer spends watching the playlist as a whole. This metric includes data for playlist
videos that are owned by other channels.
playlistEstimatedMinutesWatched
The number of minutes that users watched the playlist content as a part of the playlist. Watch
time that occurred in other contexts—for example, watch time from views that occurred when
viewers were watching the same video as part of other playlists—is not counted. This metric
includes data for playlist videos that are owned by other channels.
playlistSaves
The net number of times that users saved a playlist. See the
YouTube Help Center for more
information about saved playlists. This metric returns a net change number, meaning that if a
user saves a playlist, removes it from the list of saved playlists, and saves it again, the
metric value reflects one playlist save being added.
playlistStarts
The number of times that viewers initiated playback of a playlist. Note that this metric
includes only playlist views that occurred on the web.
playlistViews
The number of times that videos in the playlist were viewed in the context of that playlist.
This metric includes data for playlist videos that are owned by other channels.
viewsPerPlaylistStart
The average number of video views that occurred each time a playlist was initiated. Note that
this metric includes only playlist views that occurred on the web.
Note: YouTube Analytics API reports only return data for the annotationClickThroughRate
and annotationCloseRate
metrics as of June 10, 2012. In addition, YouTube Analytics API reports only return data for the remaining annotation metrics as of July 16, 2013.
The total number of annotation impressions.
annotationClickableImpressions
The number of annotations that appeared and could be clicked.
annotationClicks
The number of clicked annotations.
annotationClickThroughRate (core metric)
The ratio of annotations that viewers clicked to the total number of clickable annotation impressions. This is a core metric and is subject to the Deprecation Policy. The YouTube Help Center has more information about creating annotations and using link annotations.
annotationClosableImpressions
The number of annotations that appeared and could be closed.
annotationCloses
The number of closed annotations.
annotationCloseRate (core metric)
The ratio of annotations that viewers closed to the total number of annotation impressions. This is a core metric and is subject to the Deprecation Policy.
The YouTube Help Center contains more detailed instructions for adding cards to your videos and the YouTube Analytics Cards Report.
The number of times cards were displayed. When the card panel is opened, a card impression is logged for each of the video's cards.
cardClicks
The number of times that cards were clicked.
cardClickRate
The click-through-rate for cards, which is calculated as the ratio of card clicks to card impressions.
cardTeaserImpressions
The number of times that card teasers were displayed. A video view can generate multiple teaser impressions.
cardTeaserClicks
The number of clicks on card teasers. Card icon clicks are attributed to the last teaser displayed to the user.
cardTeaserClickRate
The click-through-rate for card teasers, which is calculated as the ratio of clicks on card teasers to the total number of card teaser impressions.
Livestream metrics (concurrent viewers)
averageConcurrentViewers
The average number of concurrent viewers for a particular video. If the livestreamPosition
dimension is specified for the report, then the
averageConcurrentViewers
valuespecifies the average number of concurrent viewers during a particular segment peakConcurrentViewers
The peak number of concurrent viewers for a particular video. If the livestreamPosition
dimension is specified for the report, then the
peakConcurrentViewers
valuespecifies the peak number of concurrent viewers during a particular segment of the video.
Audience retention metrics
audienceWatchRatio
The absolute ratio of viewers watching the video at the given point in the video. The ratio is calculated by comparing the number of times a portion of a video has been watched to the total number of views of the video. The
elapsedVideoTimeRatio
dimension identifies the portion of the video to which the metric corresponds.Note that a portion of a video could be watched more than once (or not at all) in a given video view. For example, if users rewind and watch the same portion of a video multiple times, then the absolute ratio for that portion of the video the could be greater than
1
.The following examples illustrate how the value is calculated:
A one-minute video is watched 100 times. Half of the viewers stop watching after 15 seconds and the rest watch the entire video. None of the viewers watch any parts of the video more than once. In this case, this metric's value would be
1
for time buckets in the first quarter of the video, and its value would be 0.50
for the remainder of the video.A one-minute video is watched 100 times. All of the viewers watch the entire video, but 20 of the viewers watch until the video's 45-second mark, then skip back to the video's 30-second mark, and then watch the remainder of the video. In this case, the metric's value would be
1
for time buckets in either the first half or the last quarter of the video. However, the value would be 1.2
for time buckets in the third quarter of the video since 100 percent of the viewers watched that segment of the video but 20% of those viewers watched the segment twice.relativeRetentionPerformance
A measurement that shows how well a video retains viewers during playbacks in comparison to all YouTube videos of similar length. The metric has a value between
0
and 1
that identifies the video's relative retention performance at a given point in the video. The point in the video is provided by the elapsedVideoTimeRatio
dimension.A value of
0
indicates that the video retains viewers worse than any other video of similar length, while a value of 1
indicates that the video retains viewers better than any other video of similar length. A median value of 0.5
indicates that half of the videos of similar length retain viewers better while half retain viewers worse.The following hypothetical example illustrates how the values might appear in a report. On average, 90 percent of viewers who watch videos that are 10 minutes long are still watching after three minutes and 70 percent are still watching after eight minutes. However, for a specific 10-minute-long video, only 80 percent of viewers are still watching after three minutes, but all of those viewers are still watching after eight minutes.
At the
elapsedVideoTimeRatio
value that corresponds to the point that is three minutes into the video, the relativeRetentionPerformance
metric would have a value below 0.5
since, at that time, the video performs worse than the average video.At the
elapsedVideoTimeRatio
value corresponding to the point that is eight minutes into the video, the relativeRetentionPerformance
metric would have a value higher than 0.5
since, at that time, the video is performing better than other videos of similar length.startedWatching
The number of times a particular segment of the video was the first segment seen during a
video playback.
For example, suppose Video X is 5 minutes long. For the purposes of this report, YouTube divides
the video into 100 3-second segments, which are identified with the elapsedVideoTimeRatio
dimension. A viewer visits YouTube and watches the first minute and ten seconds of the video,
which includes all or part of the first 24 segments of the video. On a subsequent YouTube visit,
the viewer watches the rest of the video, resuming playback in segment 24 and continuing through
segment 100.
This example would produce these watch metric values:
The value of the
startedWatching
metric would be 1
for segments1 and 24, and the metric value would be
0
for all other segments.The value of the
stoppedWatching
metric would be 1
for segments24 and 100, and the metric value would be
0
for all other segments.The value of the
totalSegmentImpressions
metric would be 2
forsegment 24, and the metric value would be
1
for all other segments.stoppedWatching
The number of times a particular segment of the video was the last segment seen during a
video playback. Refer to the definition of the
startedWatching
metric for anexample of how this metric value is calculated. totalSegmentImpressions
The number of times a particular segment of a video was viewed. Refer to the definition of the
startedWatching
metric for an example of how this metric value is calculated. Notethat a viewer can watch the same segment of a video multiple times in the same playback.
