How to measure and improve GPU performance

February 1, 2021

A GPU or Graphical Processing Unit is a powerful piece of hardware that we use in our computers for various applications. We use it for Gaming, 3D Modelling, Creative Workflows, and they are an essential part of your system if you plan to use it for training Machine Learning algorithms on it. It also accelerates the tasks using hardware encoders, which you can use in various software like Adobe Premiere Pro, Magix Vegas Pro, etc.

So how do you measure the performance of your GPU?

The best way to measure your GPU’s performance is by doing the tasks you intend to with it while monitoring its aspects. Various programs help you monitor your Graphics Card. Most Games have a benchmarking tool, and even the creative applications have some way to benchmark the hardware. While performing those benchmarks, you should check the GPU usage and your CPU usage and notice whether they can hold up their high speed under the workload. To measure these values, you can use the Windows Task Manager, but it is advised that you use something like MSI Afterburner as it gives very important info like the temperatures which your card is reaching.

Now that you’ve monitored the performance of your GPU, you might notice a few things, it might reach very high temperatures (90°C+), which results in thermal throttling, the CPU might be a bottleneck to your GPUs performance, or it might be that it’s working fine but still not performing well enough for your needs.

How to improve the performance of your GPU

The GPU performance can be improved in a few ways, and you squeeze out more performance from your current Graphics Card using some of these methods.

  • Overclocking

This method should be avoided if you are using a Laptop as they usually don’t have enough heat dissipation capability to handle the process, and it might end up damaging your system.

Overclocking means running the card at higher clock speeds than the current ones. You should attempt to overclock if your computer has sufficient cooling for the process.

You can use various programs to overclock your Graphics Card like MSI Afterburner; while doing the process, make sure you increase the clock speeds in small increments rather than a high value as it might result in your crashing system. While doing the process, keep an eye on your GPU’s temperatures and keep increasing until it has good thermal stats. If the weather gets too high, you should decrease the clock speed.

  • Undervolting

This process is recommended for laptops. Undervolting is a process of lowering the operating voltage of the GPU. It will limit the voltage limit and help your GPU maintain a good temperature, and increase your laptop’s longevity.

Many people confuse undervolting with underclocking and think it will reduce their laptops’ performance, but both are entirely different processes.

You can use various programs like Throttlestop, MSI Afterburner to undervolt your GPU. You might want to undervolt your CPU as well if it is thermal throttling.

  • If you are experiencing thermal throttling on your Desktop, you might want to check if your cabinet is properly cooled or not. If not, you would like to improve the cooling and airflow in your cabinet and also make sure that the fans and filters are clean and dust-free at least once every three months.
  • For laptops, you can use a cooling pad to keep your laptop cool. A cooling pad has fans attached to it, which helps release the heat from your system and assists your laptop fans in the airflow.
  • Repasting

This is also something you can do to improve GPU performance on your laptop. Repasting is when you remove the existing thermal paste on your GPU and apply new in its place. This is a selective process, so you should look for assistance if you aren’t confident doing it yourself. Using a good quality thermal paste is necessary for this process.

  • Upgrading

Sometimes even after trying everything, the performance might not be enough for you. In that case, you should upgrade your GPU if you are on a Desktop PC.

These were a few ways to improve your GPU’s performance, and sometimes it may not be enough, so you should consider upgrading your current machine. There are a plethora of videos and guides online on Overclocking and Undervolting. Make sure you search about your specific model while doing so as there isn’t a universal setting that fits them all. Now go on the adventure of analyzing and optimizing your GPU for your needs.

So, the best way out of this dilemma is to have a clear customer acquisition strategy in place.

How can you create the ideal customer acquisition strategy for your business?

  • Define what your goals are

You need to define your goals so that you can meet the revenue expectations you have for the current fiscal year. You need to find a value for the metrics –

  • MRR – Monthly recurring revenue, which tells you all the income that can be generated from all your income channels.
  • CLV – Customer lifetime value tells you how much a customer is willing to spend on your business during your mutual relationship duration.  
  • CAC – Customer acquisition costs, which tells how much your organization needs to spend to acquire customers constantly.
  • Churn rate – It tells you the rate at which customers stop doing business.

All these metrics tell you how well you will be able to grow your business and revenue.

  • Identify your ideal customers

You need to understand who your current customers are and who your target customers are. Once you are aware of your customer base, you can focus your energies in that direction and get the maximum sale of your products or services. You can also understand what your customers require through various analytics and markers and address them to leverage your products/services towards them.

  • Choose your channels for customer acquisition

How will you acquire customers who will eventually tell at what scale and at what rate you need to expand your business? You could market and sell your products on social media channels like Instagram, Facebook and YouTube, or invest in paid marketing like Google Ads. You need to develop a unique strategy for each of these channels. 

  • Communicate with your customers

If you know exactly what your customers have in mind, then you will be able to develop your customer strategy with a clear perspective in mind. You can do it through surveys or customer opinion forms, email contact forms, blog posts and social media posts. After that, you just need to measure the analytics, clearly understand the insights, and improve your strategy accordingly.

Combining these strategies with your long-term business plan will bring results. However, there will be challenges on the way, where you need to adapt as per the requirements to make the most of it.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

  • Highly calibrated cameras that take a photograph of the image from various angles.
  • Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

  • Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

  • Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

  • Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

  • Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

  • Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

  • 3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
  • It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
  • They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
  • It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
  • It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning   is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

  1. Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
  2. Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
  3. Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
  4. Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.  

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.
