How to activate ATTN key?
To activate this Attn key system, key and compile STDATNPGM, CHGATNPGM, ATN001CL and ATN001CLA according to the instructions at the bottom end of each figure. Change the system value QATNPGM or the desired user's profile ATNPGM to STDATNPGM. If you change a user's profile ATNPGM while he is signed on, you will need to sign that user off before the change will take place.
What are the parameters of SetatNPGM?
SETATNPGM has two parameters: PGM and SET.
What does "set" mean in PGM?
SET (Set) indicates whether to activate (*ON) or deactivate (*OFF) the program named in the PGM parameter as the Attention key program.
How many tasks can you execute from a single display station?
You can execute four tasks from a single display station if you combine the use of SysRq Option 1 with the Attention key.
What is the purpose of the Attention key?
The purpose of the Attention key is to execute a program whenever the Attention key is pressed. This program is usually known as the Attention key handling program, but in the rest of the article I'll drop the word handling for brevity. The program's name is specified globally in a system value (QATN-PGM) or explicitly in your user profile; the security administrator can change it with the Change User Profile (CHGUSRPRF) or Change Profile (CHGPRF) command, as follows:
What is QSYS/QWSSYSRQ?
QSYS/QWSSYSRQ: Presents the System Request menu. It lets you use the Attention key instead of the more complicated Shift-SysRq followed by Enter. Great for people who come from the S/36.

QSYS/QCMD: Presents the Command Entry panel. Now you can enter any command and have a running history of all the commands you have entered.
What happens if you manually set the weight of the last input to 1 and all its precedences to 0?
Note that if we manually set the weight of the last input to 1 and all its precedences to 0s, we reduce the attention mechanism to the original seq2seq context vector mechanism. That is, there is no attention to the earlier input encoder states.
What are the two projection vectors called?
This is essentially the approach proposed by the second paper (Vaswani et al. 2017), where the two projection vectors are called query (for decoder) and key (for encoder), which is well aligned with the concepts in retrieval systems. (There are later techniques to further reduce the computational complexity, for example Reformer, Linformer .)
How is context vector computed?
In other words, in this attention mechanism, the context vector is computed as a weighted sum of the values, where the weight assigned to each value is computed by a compatibility function of the query with the corresponding key (this is a slightly modified sentence from [Attention Is All You Need] https://arxiv.org/pdf/1706.03762.pdf ).
What happens when the input sequence is long?
However, if the input sequence is long, relying on only one context vector become less effective. We need all the information from the hidden states in the input sequence (encoder) for better decoding (the attention mechanism).
How does word2vec work?

How to improve attention?
But even people without attention problems can benefit from using strategies designed to improve attention and focus. Some things you can try include: 1 Avoiding multitasking: If you want to improve your focus, try to avoid multitasking. Trying to juggle multiple tasks hurts productivity, so you can make the most of your limited attentional research by only working on one thing at a time. 2 Getting enough sleep: Research has shown that sufficient sleep is essential for maintaining optimal levels of attention. Not only that, the two appear to have a bidirectional relationship; sleep helps regulate attention, but attentional demands can also play a role in sleep. 6 3 Practicing mindfulness: Mindfulness, which involves paying attention to the present moment, is sometimes conceived of as a form of attention. Research has shown that mindfulness training may be helpful for improving attention. 7
How to make the most of limited attentional research?

Practicing mindfulness: Mindfulness, which involves paying attention to the present moment, is sometimes conceived of as a form of attention.
What is attention in science?
Attention is the ability to actively process specific information in the environment while tuning out other details. Attention is limited in terms of both capacity and duration, so it is important to have ways to effectively manage the attentional resources we have available in order to make sense of the world.
What is the term for the ability to focus on one thing for a continuous period of time?
