What does increasing number of heads do in the Multi ...

Changing the number of heads changes the number of learnable parameters. If you have more heads, training will take longer. This is definitely true. The next bit is more of an opinion.

When you have several heads per layer the heads are independent of each other. This means that the model can learn different patterns with each head. For example, one head might pay most attention to the next word in each sentence, and another head might pay attention to how nouns and adjectives combine.

Having several heads per layer is similar to having several kernels in convolution.

Having several heads per layer allows one model to try out several pathways at once. It often turns out that some of the heads are not doing anything useful, but that’s OK because the later layers can learn to ignore the un-useful heads.

It is possible to train a model with lots of heads and then cut some of them away. This is called pruning. Note that some researchers prune away whole heads, and other researchers prune away the least useful weights within a head. I believe you can prune a model either after pre-training or after fine-tuning.

If you want to look at what patterns each individual head is learning, I recommend a visualisation tool called Bertviz by Jesse Vig. (Note that this only works for pytorch, not in Tensorflow)

As the name suggests, the multi-head scale has many "heads", that is, "weighing buckets", which are used in high-speed, high-precision quantitative weighing and packaging systems. It is suitable for fast quantitative weighing of various granular, flake, strip, spherical and other materials. Multi-head scales have many "heads", which are actually "weighing buckets". According to the types of buckets commonly used in the food packaging industry today, they are divided into 8 buckets, 10 buckets, 12 buckets, 14 buckets, 16 buckets, 20 buckets, 24 buckets bucket etc. Let's take a look at the advantages and characteristics of using a multi-head scale. The specific performance is as follows.

Main Feature:
1. During rapid weighing, the vibrator can automatically adjust the vibration amount according to different target weight values, so that the feeding is more uniform and the combination rate is higher.
2. Adopt high-precision digital load cell and AD module for accurate measurement.
3. The changeable signal CAN port and error self-diagnosis function greatly improve the time of troubleshooting and improve efficiency.
4. According to the characteristics of the object to be measured, the opening and closing speed and opening angle of the hopper door can be finely adjusted to prevent material jamming.
5. When combined weighing, you can choose to set multiple blanking and sequential blanking to avoid bulky material blocking the blanking port.
6. The aggregate processing system with the functions of "automatic sorting" and "one-to-two" can directly eliminate unqualified products and directly process the discharge signals sent by two packaging machines.
7. All parts in contact with the material are made of stainless steel, which is clean and hygienic. The fully sealed waterproof design prevents the intrusion of foreign objects and is easy to clean.
8. Two different materials can be weighed at the same time, and two different parameters can be set at the same time.
9. Set different permissions according to different operators, which is convenient for management.
10. The operating system can be used in multiple languages such as Chinese/English/Western according to customer requirements.

It can be seen from this that the weighing speed of the multi-head scale is fast—10 buckets can reach 70 bags/minute, 14 head weigher can reach 120 bags/minute, and the dynamic weighing accuracy is accurate—±0.1~2.0g, High degree of automation----integrate with elevator and packaging machine to automatically complete quantitative packaging system.
