Define Machine learning?

Machine learning (ML) is a category of the algorithm, which allows software applications to become provide more accurate predicting outcomes without being explicitly programmed. Basically, the premise of machine learning is to develop algorithms, which can receive input data and use statistical analysis to predict an output while updating the outputs as new data becomes available. The process that involved in machine learning is similar to the process of predictive modeling and data mining. The data mining and predictive modeling searching through data to look for the patterns and adjusting program actions accordingly. Software is a piece of program, which describes the intention of how a piece of hardware is going to be used. A program or software contains misunderstandings and careless mistakes, which is called as defects or bugs in programs. System failures can also occur because of some bugs or defects such as double free, null pointer deference. There are many people who are familiar with the usage of machine learning in form of e-commerce and digital advertisement. This happens due to the recommendation engines use machine learning to categorize online ad delivery in almost real-time. Beyond the personalized marketing, other common machine learning use cases that include fraud detection, network security threat detection, spam filtering, and fraud detection, building news feeds and predictive maintenance.

What is automated bug detection?

Automated bug detection is an increasingly popular technique to analyze the programming error and other machine learning quality issues. Traditionally, the bug detectors are program analysis, which is manually written and carefully tuned by an analysis expert. Unfortunately, the large amount of possible bug patterns makes it tough for covering more than a small fraction of entire bugs. The basic idea of automated bug detection is to replace manually writing a program analyst with the training a machine learning model, which distinguishes buggy from non-buggy codes. Effective learning needs both negative and positive training in order to address the challenges. DeepBugs is a framework, that can be used by the organizations to identify programming mistakes in unseen code. There are four bug detectors that are used for the detection of programming mistakes in JavaScript. These detectors not only identify semantic errors in the code, along with that they can also identify syntax errors in the unseen code that can be happened due to the negligence of programmer. Moreover, in order to find bugs, the trained machine learning models use information that is usually discarded by the program analyses, such as identifiers names of variables and function. The techniques of automated bug detections are widely used by developers and have received significant attention from researchers. There are many popular techniques such as light-weight, static analysis, lint-style, which search for instances of known bug patterns. Basically, such analyses are created as part of a framework, which supports an extensible set of bug patterns, like Google error-prone.

How to detect?

Some straightforward and simple methodologies to detect the missing method calls would be used to build a set of hard-coded rules such as:

• After instantiating a TextView, always call set control () method.

• Always call setContentView() method in the Method onCreate().

• when calling next () on an Iterator always call has Next () (before).

Well-reasoned and well-crafted rules along these lines could facilitate accurate detection of missing method calls and contribute to less and better buggy code. Though, maintaining and formulating a list of rules like this needs manual effort and likely demands tremendous amounts of money and time. While the effort might even be justified for important and large libraries, it multiplies with the size of the library to the point of being entirely infeasible.

There is an automated detecting location in a codebase machine learning model, where a method call is potentially missing, using only the code itself as input. This type of methodology would adapt to changes without requiring additional work from a developer and also could be applied to the proprietary code that is closed to the public. Further, the approach did not provide accurate result as compared to the handcrafted list of rules, but the manual examination by an expert can be helpful in providing accurate results. This would determine the severity of the problem and, and also fix necessary. Whether this will be beneficial to save money and time hinges on the accuracy of the approach.

What are the different types of tools and techniques of automated bugs detecting?

There are many types of tools and techniques in machine learning that are used to automatically detect bugs:

• Finding code smells with hard-coded rules
• Android-specific Smell Detection
• Learning from the analyzed Code
• Detecting Method Call Anomalies
• Detecting Missing Method Calls
• Investigating different Anomalies
• Superfluous Method
• Bytecode Analysis
• Extracting Type Usages
• Improvements and Dead Ends
