Today’s Machine learning (ML) is a lot different from the machine learning of the past. New computing technologies have changed the way it works (not the architecture it’s based on, i.e., learning from pattern recognition).
Although numerous ML algorithms have been around for a long time, the ability to carry out complex mathematical calculations in big data and deliver faster and more accurate results is a recent development.
The past couple of years were a good year for the freedom of information, as tech giants like Microsoft, Google, Amazon, Facebook, and even Baidu open-sourced a few of their ML frameworks.
Working within the ML landscape while using the right tools can be very helpful for developers who are trying to build a productive algorithm that taps into its power. We’ve gathered some of the best machine learning tools and resources of this year that will help you seamlessly integrate the power of ML into everyday tasks.

6. Apple’s Core ML
Plus Point: Optimized for on-device performance
Core ML offers a simple way to integrate trained machine learning models into macOS, iOS, and tvOS apps. All you need to do is drop the mlmodel file into your project, and Xcode will automatically create an Objective-C or Swift wrapper class, making it really easy to use the model.
It supports Natural language processing, image classification, word tagging, sentence classification, object tracking, barcode detection, and GameplayKit for the evaluation of learned decision trees.
Since the framework is built on top of low-level technologies like Metal and Accelerate, it can leverage both CPUs and GPUs to provide maximum performance.
Moreover, running models strictly on the device ensures privacy and guarantees that the application remains functional when you are not connected to the internet.
Plus Point: Sequential models only require a single line of code for one layer.
Released in 2015, the open-source neural network library Keras focuses on being modular, user-friendly, and extensible. In 2017, Google started supporting Keras in TensorFlow’s core library.
It has multiple pre-defined layers arranged into categories: core, locally connected, embedding, normalization, noise, convolutional, pooling, and advanced activations. There is also an API for writing layers.
Each layer performs a specific task. Usually, they pass most of the compute-intensive operations to the backend, such as Microsoft Cognitive Toolkit or TensorFlow.
Along with standard neural networks, Keras also supports recurrent and convolutional networks. It provides 7 of the common deep learning sample data and ten well-known models pre-trained against ImageNet.
4. Apache MXNet
Plus Point: Scales to multiple GPUs across multiple hosts with 85% efficiency.
Adopted by Amazon as its primary deep learning framework on AWS, MXNet can scale almost linearly across several GPUs and servers. It is built to be distributed on dynamic cloud infrastructure via a distributed parameter server.

More to Know
How many types of machine learning are there?
Machine learning can be categorized into three major groups —
1) Supervised: In this type of learning, algorithms are trained on a historical input and output. These algorithms gradually learn to predict outcomes based on the historical (test) dataset.
Linear regression, decision trees, support vector machines, and neural networks are examples of supervised machine learning. They are widely used for fraud detection, inventory optimization, and data forecasting.
2) Unsupervised: In this type of learning, algorithms look for obvious patterns in data. They find relationships among data points in an abstract manner, with no input required from human beings.
Hierarchical clustering, Hidden Markov models, and Gaussian mixture models are the most common examples of unsupervised machine learning algorithms. They are used in network analysis, anomaly detection, and recommendation systems.
3) Reinforcement: In this type of learning, algorithms improve upon themselves and learn from new scenarios using a trial-and-error method. Good outputs are encouraged (reinforced) while bad ones are discouraged (punished).
Q-learning, deep adversarial networks, and temporal difference are common reinforcement learning examples. Their real-world use cases include resource management, text mining, and building intelligent robots and smart programs like AlphaGO Zero.
