Introduction to Deep Learning and Machine Learning
1. What is Machine Learning?
Machine Learning is the scientific study of statistical models and algorithms that computer systems use to perform a task without explicit instructions. Machine Learning is a comprehensive field that involves various functionalities of machine learning operations like clustering, classification and development of predictive models.
Basically, Machine Learning allows computers to learn without an explicit need for programming.
In general programming scenarios, you have to provide instructions to the computer for it to provide you with the output. However, with the help of machine learning algorithms, you can train your computer to provide you with the output with the need to give instructions. A machine learning algorithm is able to do so with the help of data. Using the data fed to the system, a machine learning algorithm is trained to provide output to the users. There are three main types of machine learning algorithms –
1.1 Supervised Learning
In a supervised learning algorithm, the input data is labeled such that the data is organized. The computer is able to follow the examples of input-output pairs and train the model to fit the data with good accuracy. Some of the supervised learning algorithms are –
- Linear & Multivariate Regression
- Logistic Regression
- Naive Bayes
- Decision Trees
- K-nearest neighbour
- Linear Discriminant Analysis
- Artificial Neural Networks
1.2 Unsupervised Learning
In Unsupervised Learning, the data is not labeled or categorized. In Unsupervised learning, the data is able to organize itself after it follows a certain pattern in the way the data is distributed. Unsupervised learning algorithms are complex and are currently under research. Some of the unsupervised learning algorithms are –
- Clustering Analysis
- Anomaly Detection
- Hierarchical Clustering
- Principal Component Analysis
1.3. Reinforcement Machine Learning Algorithms
We use these algorithms to choose an action. Also, we can see that it is based on each data point. Moreover, after some time the algorithm changes its strategy to learn better. Also, achieve the best reward.
Machine Learning is used in various industries that require future prediction, identification of patterns and autonomous decision making. It is widely used in healthcare, finance, banking, manufacturing and transportation sectors.
2. What is Deep Learning?
Deep Learning is a recent field that occupies the much broader field of Machine Learning. Deep Learning is most famous for its neural networks such as Recurrent Neural Networks, Convolutional Neural Networks, and Deep Belief Networks. While other machine learning algorithms employ statistical analysis techniques for pattern recognition, Deep learning is modeled after the neurons of the human brain.
They are modeled after the structure and functioning of the human brain. In order to understand deep learning, we have to understand how the nervous system in the human body works. As we all know that our nervous system is built up of neurons. These neurons are able to grasp information that is transmitted to our body. These neurons have the ability to learn information over time. This principle of ‘learning’ is also utilized by artificial neural networks.
Any Deep neural network will consist of three types of layers:
- The Input Layer
- The Hidden Layer
- The Output Layer
In the above example, the layers are present in the form of input layer, that takes the input data. The hidden layer, which performs various computation on the input data and the output layer, which in the above visualization is binary. It is to be noted that a neural network can have multiple hidden layers.
These neural networks are used to predict the output as well as perform classification on the data. The standard notion is that the neural network learns the pattern of data, then performs predictions that fall in the same line as the pre-specified pattern.
Deep Learning vs Machine Learning
We use a machine algorithm to parse data, learn from that data. And make informed decisions based on what it has learned. Basically, deep learning is used in layers to create an artificial “neural network”. That can learn and make intelligent decisions on its own.
Let’s understand the comparison of deep learning vs machine learning through their features –
1. Data dependencies
Performance is the main key difference between both algorithms. Although, when the data is small, deep learning algorithms don’t perform well. This is the only reason Deep Learning algorithms need a large amount of data to understand it perfectly.
But, we can see the use of algorithms with their handcrafted rules prevail in this scenario. Above image summarizes this fact.
2. Hardware dependencies
3. Feature engineering
It’s a general process. In this, domain knowledge is put into the creation of feature extractors. Also, to reduce the complexity of the data. Further, make patterns more visible to learn algorithm working. Although, it’s very difficult to process. Hence, it’s time consuming and expertise.
4. Problem Solving approach
Generally, we use traditional algorithm to solve problems. Although, it needs to break a problem into different parts. Further, solve them individually. Moreover, to get a result, combine them all.
For Example –
You have a task of multiple object detection. Although, in this task we have to identify what is the object and where is it present in the image. Further, in a machine learning approach, we have to divide the problem into two steps:
- Object detection
- Object recognition
First, we use grabcut algorithm to skim through the image and find all the possible objects. Then of all the recognized objects, you would then use object recognition algorithm like SVM with HOG to recognize relevant objects.
5. Execution time
We have interpretability as a factor for comparison of both learning techniques. Although, deep learning is still thought 10 times before its use in industry.
