What Exactly Is Artificial Intelligence?

Artificial intelligence has been a hot topic in the software development industry for some time now. But what exactly is artificial intelligence? In its simplest form, artificial intelligence is the ability of a computer to perform tasks that normally require human intelligence, such as understanding natural language and recognizing objects. However, artificial intelligence can also be used to create more sophisticated applications that can learn and adapt as they are used. As artificial intelligence technology continues to evolve, it is likely that we will see even more amazing applications of this powerful tool in the future.

What Is A Neural Network?

Neural networks are a type of artificial intelligence that are modeled after the brain. Neural networks are composed of neurons, which are connected to each other. The connections between neurons can be weighted, so that some connections are stronger than others. Neural networks learn by adjusting the weights of the connections between neurons. Neural networks are often used in pattern recognition, such as image recognition or facial recognition. Neural networks can also be used for regression, which is when the output of a neural network is a continuous value, such as a real number. Neural networks are sometimes called artificial neural networks or parallel distributed processing systems.

Neural Network: Keras 4 Delphi

What is Keras?

Keras is a high-level neural networks API, written in Python and capable of running on top of TensorFlow, CNTK, or Theano. It was developed with a focus on enabling fast experimentation. Being able to go from idea to result with the least possible delay is key to doing good research. Keras has the following key features: allows the same code to run seamlessly across CPU and GPU devices, supports both convolution based networks and recurrent networks (as well as their combinations),runs seamlessly on CPU and GPU devices. Keras is compatible with Python 3.5-3.7 and is distributed under the MIT license. Keras was created by Google engineer François Chollet.

Keras4Delphi is a neural network API that allows for highly productive prototyping and it supports convolutional networks and recurrent networks. It runs on both the CPU and GPU. It can run on top of TensorFlow, CNTK, or Theano.

What is TensorFlow Lite?

TensorFlow Lite is a set of tools to help developers run TensorFlow models on mobile, embedded, and IoT devices. It enables on-device machine learning inference with low latency and a small binary size. TensorFlow Lite supports a subset of the operations in the full TensorFlow API. This makes it possible to deploy machine learning models on devices with very limited computational resources. For example, TensorFlow Lite can run on a Raspberry Pi with just 1GB of RAM. In addition, TensorFlow Lite supports a number of hardware accelerators, which can further improve performance. Overall, TensorFlow Lite provides a powerful and efficient way to run machine learning models on resource-constrained devices.

TensorFlow Lite for Delphi is a library containing a set of tools that enables machine learning on a wide variety of devices including Windows 11/10/8/7. There are three demos built in Delphi that demonstrate the usage of the TensorFlow Lite library. These demos include a digit classifier, face detection, and object detection.

What Is Deep Learning?

Deep learning is a branch of machine learning that deals with algorithms inspired by the structure and function of the brain called artificial neural networks. Neural networks are used to recognize patterns, cluster and classify data, and make predictions based on data. Deep learning is a neural network with multiple layers that can learn increasingly abstract representations of data. The first layer of a deep learning network learns low-level features such as edges, while the last layer learns high-level features such as shapes or objects. Many deep learning networks are trained by feeding them large amounts of data and allowing them to learn from the data themselves. This is different from traditional Machine Learning algorithms, which require human input to learn from data. Deep learning is often used for image recognition, speech recognition, and natural language processing tasks.

Deep Learning: PyTorch with Delphi

What is PyTorch?

PyTorch is a Python-based open-source scientific computing package for deep learning that accelerate the pace of machine learning and artificial intelligence research. Pytorch provide two high-level features:

Tensor computation (like NumPy) with strong acceleration via GPUs
Build, train and deploy deep neural networks on a tape-based autograd system.

A number of pieces of deep learning software are built on top of PyTorch, including Tesla Autopilot, Uber’s Pyro, HuggingFace’s Transformers, PyTorch Lightning, and Catalyst. You can reuse your favorite Python packages such as NumPy, SciPy, and Cython to extend PyTorch when needed.

How Is Artificially Intelligence Being Used?

Many people think of artificial intelligence (AI) only in terms of movies and television shows in which computers become sentient beings. However, artificial intelligence is already being used extensively in the field of software development. AI can be used to create software that can learn and adapt to new situations, as well as to automate repetitive tasks. In many cases, AI-powered software is able to outperform its human counterparts. For example, Google’s AlphaGo artificial intelligence system beat a professional Go player in a five-game match in 2016. As artificial intelligence continue to evolve, it is likely that even more amazing feats will be achieved in the field of software development.

Machine Learning: 5 Ways To Use ML in your Windows Apps

How do I start using Machine Learning in Windows?

Machine Learning is a branch of artificial intelligence that deals with the design and development of algorithms that can learn from and make predictions on data. Machine Learning algorithms have been used in a variety of applications, such as spam detection, facial recognition, and disease diagnosis. In recent years, there has been an increasing interest in Machine Learning, due to the availability of large data sets and advances in computing power.

Windows is a popular operating system for personal computers, laptops, and servers. There are many Machine Learning software packages available for Windows, such as Orange, WEKA, and Microsoft Azure Machine Learning Studio. In order to start using Machine Learning on Windows, you will need to choose a software package and install it on your computer. Once you have installed the software, you will need to gather data that you want to use for training your Machine Learning algorithm. This data can be in the form of text, images, or videos. Once you have gathered your data, you will need to split it into two sets: a training set and a test set. The training set is used to train your Machine Learning algorithm, while the test set is used to evaluate the performance of your algorithm.

After you have trained your algorithm on the training set, you can then use it to make predictions on the test set. Machine Learning is a powerful tool that can be used to solve a variety of problems. By using Machine Learning on Windows, you can take advantage of this technology without having to purchase expensive cloud solutions.

Python4Delphi (P4D) empowers Python users with Delphi’s award-winning VCL functionalities for Windows, which enable us to build native Windows apps 5x faster. This integration enables us to create a modern GUI with Windows 10 looks and responsive controls for our Python Machine Learning applications.

What is the DeepAI API?

The primary motivation behind designing AI solutions is to study data and predict meaningful insights out of the data. In today’s world, where businesses are producing loads and loads of data, AI serves its best purpose by providing various kinds of predictive outcomes for the companies.

Some sample DeepAI APIs include Colorizer, Image Similarity, Super Resolution, Fast Style Transfer, DenseCap, Toonify, and Content Moderation.

Example:

var
  MS: TMemoryStream;
  IMG: TJPEGImage;
  IdHTTP1 : TIdHTTP;
begin
  MS := TMemoryStream.Create;
  IdHTTP1 := TIdHTTP.Create(nil);
  try
    IMG := TJPEGImage.Create;
    try
        MS.Clear;
        urls := StringReplace(urls, 'https', 'http', [rfReplaceAll, rfIgnoreCase]);
        IdHTTP1.Get(urls, MS);
        MS.Position := 0;
        MS.SaveToFile(resourcesDirectory + '\output.jpg');
        IMG.LoadFromStream(MS);
        ImgResult.Picture.Assign(IMG);
        Application.ProcessMessages;

    finally
      IMG.Free;
    end;
  finally
    MS.Free;
  end;

var

MS: TMemoryStream;

IMG: TJPEGImage;

IdHTTP1 : TIdHTTP;

begin

MS := TMemoryStream.Create;

IdHTTP1 := TIdHTTP.Create(nil);

try

IMG := TJPEGImage.Create;

try

MS.Clear;

urls := StringReplace(urls, 'https', 'http', [rfReplaceAll, rfIgnoreCase]);

IdHTTP1.Get(urls, MS);

MS.Position := 0;

MS.SaveToFile(resourcesDirectory + '\output.jpg');

IMG.LoadFromStream(MS);

ImgResult.Picture.Assign(IMG);

Application.ProcessMessages;

finally

IMG.Free;

end;

finally

MS.Free;

end;

Computer Vision: Microsoft Cognitive Services

What are Microsoft Cognitive Services?

Implements the FaceAPI service from Microsoft. Features detecting up to 10 faces in a photo with face attribute support for gender, age, emotion, hair style, and sun classes. It is also able to identify a person if they have previously been added.

Microsoft’s Azure has a broad collection of services you can access with an easy-to-use API.

Azure is Microsoft’s cloud hosting and computing platform with a catalog of more than 200 different products. It also includes products which allow you to implement Machine Learning services. Those services all have an API which you can access using client access libraries or a REST client. Delphi takes this ease of use one step further by providing a TAzureConnectionInfo to implement some of those services quickly and with a minimal amount of code.
