彼时，诺和诺德的“方案销售”培训项目面临挑战。一方面，项目预算减少，而传统培训方式耗资较大；另一方面，培训时间不足——销售部门业绩压力大，分配给培训的时间本就不多，传统培训模式耗时长，他们时常无暇参与。

在一支宣传片中，诺和诺德这样描述 uShow ：“她从不生气，她对你没有偏见，她不知疲倦地帮助你，她给你的反馈总是很及时，她的意见总是基于事实和数据。没有人愿意为你一遍又一遍地反馈，除了 uShow 。”
UMU互动学习平台
数据显示，约半年时间中，uShow 功能覆盖的销售人数达 3000 余人，合计练习次数 53306 次，人均练习 14-15 次，而合计练习时间近 92 万分钟。

And this happens to be what the dataset we’re using is all about. It contains a class feature called intent, and to demonstrate a classification task, we’ll bring it in this time.
Text Embeddings Visually Explained
A common approach is keyword-matching, but the problem with this is that the results are limited to the exact query entered. What if we could have a search capability that can surface results based on the context or semantic meaning of a query?
Text Embeddings Visually Explained
A large language model has been pre-trained with a vast amount of text data, where the training objective is set up in such a way to encourage the model to extract contextual information about a piece of text and store it as embeddings.
Text Embeddings Visually Explained
The endpoint comes with a few model-size options. Larger models have a higher number of dimensions. Each dimension stores one additional piece of information about the text, so as the number of dimensions increases, the representational power increases.
Text Embeddings Visually Explained
But another thing you can get is text representation: a set of numbers that represent what the text means, and somehow capture the semantics of the text. These numbers are called text embeddings.
Text Embeddings Visually Explained
Text Embeddings give you the ability to turn unstructured text data into a structured form. With embeddings, you can compare two or more pieces of text, be it single words, sentences, paragraphs, or even longer documents.

With GPT-3 specifically, you have a number of different variables to take into account that make it different from other summarization architectures. Parameters such as temperature, prompt size, token limit, top_p, and goal task are just a few of the things to manage with a GPT-3 text summarizer.

We should discuss the two main types of summarization before diving into actual GPT-3 summarization. Extractive and abstractive summarization are two different methods to create a summary of a given input text.

With cursor pagination, when the user clicks next or previous to see a new page, it will take only 0.18 seconds to load. With offset pagination, the same action will take 13 seconds! That means each page will take 13 seconds to load. That is like forever in computing years!

Let us see a way to assign a probability to a word occurring next in a sequence of words. First of all, we need a very large sample of English sentences (called a corpus).
An Introduction to N-grams: What Are They and Why Do We Need Them? - XRDSXRDS
For instance, a bigram model (N = 2) predicts the occurrence of a word given only its previous word (as N – 1 = 1 in this case). Similarly, a trigram model (N = 3) predicts the occurrence of a word based on its previous two words (as N – 1 = 2 in this case).

Basically, an N-gram model predicts the occurrence of a word based on the occurrence of its N – 1 previous words.

It can also help to make spelling error corrections. For instance, the sentence “drink cofee” could be corrected to “drink coffee” if you knew that the word “coffee” had a high probability of occurrence after the word “drink” and also

It can also help make next word predictions. Say you have the partial sentence “Please hand over your”. Then it is more likely that the next word is going to be “test” or “assignment” or “paper” than the next word being “school”.

the overlap of letters between “cofee” and “coffee” is high

One way to fix the deadlock problem is by closing the channel. Closing a channel means that you can no longer communicate on it. Note that it only makes sense for a sender, not a receiver, to close a channel because the receiver does not know if it has received everything or not. Now let’s try closing the channel:
Concurrency in Go with Goroutines and Channel - Knoldus Blogs
Finally, we reached a deadlock. So I just changed the for loop condition in the main loop from i < 5 to i < 6. As a result, the main routine is blocked on <-myIntChannel because the sending operation has sent only 5 values which were received by the 5 iterations of the loop. However, for the 6th iteration, there is no sending operation that will send value on the channel. Therefore, the program is blocked on the receiving operation resulting in a deadlock.
Concurrency in Go with Goroutines and Channel - Knoldus Blogs
This means: When we send data into the channel using a GoRoutine, it will be blocked until the data is consumed by another GoRoutine. When we receive data from channel using a GoRoutine, it will be blocked until the data is available in the channel.

The most important point to note is that both the following statements were blocking operations myIntChannel <- i and <-myIntChannel.

Concurrency in Golang is the ability for functions to run independently of each other. Parallelism is a run-time property where two or more tasks are being executed simultaneously. Through concurrency, you want to define a proper structure for your program. Concurrency can use parallelism for getting its job done but remember parallelism is not the ultimate goal of concurrency. Go has rich support for concurrency using goroutines and channels.

Since Server-Sent Events is based on the HTTP protocol, scaling can be achieved with means such as load-balancing. However, you’d need to ensure some sort of shared resource behind the servers so they’re all kept in sync with new event updates.

What Server-Sent Events is - and how and when to implement it | Ably Realtime
But it doesn’t always work well so the server doesn’t always immediately realise a connection is lost. However, this is a minor limitation to SSE.
What Server-Sent Events is - and how and when to implement it | Ably Realtime
The major limitation of SSE is that it’s unidirectional so there’s no way to pass information to a server from a client. The only way to pass additional data is at the time of connection, which many developers choose to do with query strings.
What Server-Sent Events is - and how and when to implement it | Ably Realtime
The server leaves the HTTP response open until it has no more events to send, it decides that the connection has been open long enough and can be considered stale, or until the client explicitly closes the initial request.
What Server-Sent Events is - and how and when to implement it | Ably Realtime
In a nutshell, a server-sent event is when updates are pushed (rather than pulled, or requested) from a server to a browser.

It is always considered a good practice to keep mutex close to the data they are intending to protect. Consider a struct that wants to control how its fields are accessed and modified, using mutex embedded in the struct will make it possible to control field usage in a struct.
