Deploying Machine Learning On Real Time Systems

The three critical steps involved in deployment of machine learning algorithm and exposing it to real world are :

Define a goal based on a metric : Decide if you want human level intelligence or an acceptable one as this decision will affect time and engineering cost of your system. Also define a metric to measure performance of your model.

Build the system : Build a minimum viable system without worrying much about accuracy. Then build an incremental strategy to improve your system by solving problems you face in each iteration.

Refine the system with more data : Initial metric values are not the indicators of real life, your data and users might change , so regularly monitor the system performance. Update it with new data and fine tune the model accordingly.

Enhancing Artificial Intelligence using Ensemble Training

Sometimes even the Machine learning algorithms behave so dumb that an image recognition model can be confused by generating an adversarial instance, i.e. by changing few pixels by either taking derivative of model output or exploiting genetic algorithms. Adversarial instances lie in low probability regions which is in contrast with limited instances of high probability regions from which the model was trained. A possible approach to solve this problem is ensemble training - To let multiple models back each other. As we look forward to developing more artificial intelligent systems it would become common to encounter such problems.

Defy Automation To Protect Your job

In the digital era where an individual is afraid of losing jobs not to recession, but two robots and machine learning, it becomes important for us to learn about the extent to which machines can replace human beings. In the near future where automation might delete few occupations entirely, it is expected to affect almost all occupations to some degree. Knowledge about technical feasibility is a prerequisite for automation of the activity. The second major factor that is always the reason for concern is cost. The cost of developing such automation system needs to be taken care of. Physical activities are most susceptible to automation. The retail industry is another place where automation would do wonders. However, financial sector lies in the middle range of automation. People managing and developing things can still relax a bit as automation in this field has very low technical potential. The focus should be on automating sectors with high technical feasibility and replacement of workers from these sectors to opportunities where automation is yet to do wonders.

Predictive about Politics

Nowadays, computers solve crimes, drive cars, cure sickness and accurately predict political races. But the problem is, it's not enough to just store, access and process data. Machine learning and artificial intelligence algorithms are divided into two factors: huge quantities of timely and accurate data. There are four typical methods to be used to acquire data. They are -1. Required self-declared data,2. Self-declared or observed data 3. Volunteered self-declared data, 4. Crowdsourced observed data.

Artificial intelligence and machine learning. Are they same?

Artificial intelligence and machine learning. Are they same?

Artificial intelligence is like machine learning. But they are completely different and some concepts related to it has to be cleared.

1. Artificial intelligence refers to a broad set of methods, algorithms and technologies that makes the software 'smart' that seem human-like to an outside observer.

2. Machine learning has some elementary engineering sensibility whereas artificial intelligence is more correlated to automation and sophisticated data handling.

3. Machine learning covers multiple technology, whereas AI is a process which only refers wide variety of algorithms and methodologies that enable software improvement.

4. Machine learning is more into deeper analysis, segmentation and networking in contrast to standalone operation of artificial intelligence

 

5. Cognitive understanding is more prominent in artificial intelligence because analytics and forecasting play a clinical role. So, accuracy in automation required cognitive learning.
