How to Improve a Machine Learning Algorithm: Regularization

If the machine learning algorithm does not work as well as you expected, almost all the time it happens because of bias or variance. The algorithm may be suffering from either underfitting or overfitting or a bit of both. It’s important to figure out the problem to improve the algorithm.

Bias vs Variance

Think of polynomial regression. As we know if we increase the degree of the polynomial, accuracy goes higher. But this accuracy is on the training set. If the degree of the polynomial is high enough, the algorithm learns the training data so well that it can fit in the training dataset perfectly. Look at the picture below. Higher the degree of the polynomial, the lower the training error becomes.

Cross-validation data has an interesting part to play here. When the degree of the polynomial is lower, Both training errors and the validation errors will be high. This is called a high bias problem. You can call it an underfitting problem as well. So, the sign of a high bias problem is, the training set accuracy and the validation set accuracy both are low.

On the other hand, when the degree of the polynomial is too high, training data will fit too well in the algorithm. So, the training error will be very low. But the algorithm will perform very poorly on the cross-validation data. So, the cross-validation error will be very high. This is called a high variance problem or an overfitting problem. The sign of an overfitting problem or a high variance problem is, the training set accuracy will be very high and the cross-validation set accuracy will be poor.

Regularization

Regularization helps to deal with overfitting or underfitting problem. Choosing the regularization parameter lambda can be critical.

Here is the equation for the hypothesis (on top) and the cost function (at the bottom) for polynomial regression. If we choose too large of a lambda such as 10000, the theta values except for theta0 will be insignificant. Because all the theta values are randomly initialized values that are the values between 0 to 1. In that case, the hypothesis will be:

As a result, we will have a high bias (underfitting) problem. If the lambda is too small, in a higher-order polynomial, we will get a usual overfitting problem. So, we need to choose an optimum lambda.

How to Choose a Regularization Parameter

It is worth spending some time to choose a good regularization parameter. We need to start by taking a few lambda values starting from zero. Here is the step by step process:

1. Choose some lambda values such as 0, 0.02, 0.04, 0.08, 0.1, …. 10.24.
2. Use these lambdas and train the model using the training set and minimize the cost. So, we will get a minimized cost and theta values for each lambda value.
3. Use the optimized theta values and calculate the cost functions for the cross-validation dataset.
4. Find out which lambda value gave the smallest cost in the cross-validation set. That lambda value should be our final regularization parameter. In the chart below, say, j-cv(3) is the smallest. The final regularization parameter lambda will be 0.04. In this chart, I tried to list all the steps.

Pros and Cons of Machine Learning Language

Amid all the promotion around Big Data, we continue hearing the expression “AI”. In addition to the fact that it offers a profitable vocation, it vows to tackle issues and advantage organizations by making expectations and helping them settle on better choices. In this blog, we will gain proficiency with the Advantages and Disadvantages of Machine Learning. As we will attempt to comprehend where to utilize it and where not to utilize Machine learning.

In this article, we discuss the Pros and Cons of Machine Learning.
Each coin has two faces, each face has its property and highlights. It’s an ideal opportunity to reveal the essence of ML. An extremely integral asset that holds the possibility to reform how things work.

Pros of Machine learning

1. **Effectively recognizes patterns and examples **

AI can survey enormous volumes of information and find explicit patterns and examples that would not be evident to people. For example, for an online business site like Amazon, it serves to comprehend the perusing practices and buy chronicles of its clients to help oblige the correct items, arrangements, and updates pertinent to them. It utilizes the outcomes to uncover important promotions to them.

**Do you know the Applications of Machine Learning? **

2. No human mediation required (mechanization)

With ML, you don’t have to keep an eye on the venture at all times. Since it implies enabling machines to learn, it lets them make forecasts and improve the calculations all alone. A typical case of this is hostile to infection programming projects; they figure out how to channel new dangers as they are perceived. ML is additionally acceptable at perceiving spam.

3. **Constant Improvement **

As ML calculations gain understanding, they continue improving in precision and productivity. This lets them settle on better choices. Let’s assume you have to make a climate figure model. As the measure of information you have continues developing, your calculations figure out how to make increasingly exact expectations quicker.

4. **Taking care of multi-dimensional and multi-assortment information **

AI calculations are acceptable at taking care of information that is multi-dimensional and multi-assortment, and they can do this in unique or unsure conditions. Key Difference Between Machine Learning and Artificial Intelligence

5. **Wide Applications **

You could be an e-posterior or a social insurance supplier and make ML work for you. Where it applies, it holds the ability to help convey a considerably more close to home understanding to clients while additionally focusing on the correct clients.

**Cons of Machine Learning **

With every one of those points of interest to its effectiveness and ubiquity, Machine Learning isn’t great. The accompanying components serve to confine it:

1.** Information Acquisition**

AI requires monstrous informational indexes to prepare on, and these ought to be comprehensive/fair-minded, and of good quality. There can likewise be times where they should trust that new information will be created.

2. **Time and Resources **

ML needs sufficient opportunity to allow the calculations to learn and grow enough to satisfy their motivation with a lot of precision and pertinence. It additionally needs monstrous assets to work. This can mean extra necessities of PC power for you.
**
Likewise, see the eventual fate of Machine Learning **

3. **Understanding of Results **

Another significant test is the capacity to precisely decipher results produced by the calculations. You should likewise cautiously pick the calculations for your motivation.

4. High mistake weakness

AI is self-governing yet exceptionally powerless to mistakes. Assume you train a calculation with informational indexes sufficiently little to not be comprehensive. You end up with one-sided expectations originating from a one-sided preparing set. This prompts unessential promotions being shown to clients. On account of ML, such botches can set off a chain of mistakes that can go undetected for extensive periods. What’s more, when they do get saw, it takes very some effort to perceive the wellspring of the issue, and significantly longer to address it.

**Conclusion: **

Subsequently, we have considered the Pros and Cons of Machine Learning. Likewise, this blog causes a person to comprehend why one needs to pick AI. While Machine Learning can be unimaginably ground-breaking when utilized in the correct manners and in the correct spots (where gigantic preparing informational indexes are accessible), it unquestionably isn’t for everybody.
