1 00:00:00,050 --> 00:00:02,480 Lesson tracking AI system performance. 2 00:00:02,480 --> 00:00:08,600 Post-deployment tracking AI system performance post-deployment is crucial for ensuring that artificial 3 00:00:08,600 --> 00:00:14,480 intelligence applications continue to operate effectively, ethically, and safely over time. 4 00:00:15,230 --> 00:00:21,110 Once an AI system is deployed, it transitions from a controlled development environment into a dynamic, 5 00:00:21,110 --> 00:00:27,440 real world context where it is exposed to a broader range of variables and unforeseen circumstances. 6 00:00:27,470 --> 00:00:33,170 This necessitates ongoing performance monitoring to detect and address issues such as model drift bias 7 00:00:33,170 --> 00:00:34,790 and system degradation. 8 00:00:35,480 --> 00:00:41,270 Effective tracking of AI performance involves a combination of technical, ethical, and regulatory 9 00:00:41,270 --> 00:00:45,620 considerations, each contributing to the overall governance of AI systems. 10 00:00:46,940 --> 00:00:50,210 Model drift is a common challenge faced post-deployment. 11 00:00:50,300 --> 00:00:56,150 It occurs when the statistical properties of the target variable change over time, resulting in a decrease 12 00:00:56,150 --> 00:00:57,560 in the model's accuracy. 13 00:00:57,830 --> 00:01:04,160 This can be due to various factors such as changes in user behavior, market dynamics, or environmental 14 00:01:04,160 --> 00:01:05,030 conditions. 15 00:01:05,480 --> 00:01:11,540 For instance, an AI model designed for fraud detection in financial transactions may become less effective 16 00:01:11,540 --> 00:01:13,940 if fraudsters adopt new tactics. 17 00:01:14,480 --> 00:01:19,910 Therefore, continuous monitoring and periodic retraining of the model with updated data are essential 18 00:01:19,910 --> 00:01:22,490 to maintain its accuracy and reliability. 19 00:01:23,120 --> 00:01:29,030 Automated monitoring systems can alert data scientists to significant deviations in the model's performance 20 00:01:29,030 --> 00:01:31,910 metrics, enabling timely interventions. 21 00:01:33,830 --> 00:01:38,690 Bias detection and mitigation are critical in post-deployment performance tracking. 22 00:01:39,380 --> 00:01:46,010 AI systems can inadvertently perpetuate or even exacerbate existing biases present in the training data. 23 00:01:46,520 --> 00:01:52,040 These biases can lead to unfair or discriminatory outcomes, which are particularly problematic in high 24 00:01:52,040 --> 00:01:56,060 stakes applications such as hiring, lending, and law enforcement. 25 00:01:56,090 --> 00:02:02,090 Researchers have highlighted instances where facial recognition systems exhibit higher error rates for 26 00:02:02,090 --> 00:02:06,890 certain demographic groups, raising concerns about their fairness and equity. 27 00:02:07,940 --> 00:02:13,640 Post-deployment monitoring must include tools and techniques for bias detection, such as fairness metrics 28 00:02:13,640 --> 00:02:16,760 that assess disparate impact across different groups. 29 00:02:17,480 --> 00:02:22,910 Additionally, organizations should implement governance frameworks that mandate regular audits and 30 00:02:22,910 --> 00:02:26,150 corrective actions to address identified biases. 31 00:02:27,830 --> 00:02:32,570 System degradation over time is another aspect that needs to be closely monitored. 32 00:02:32,600 --> 00:02:38,600 AI models can degrade due to several reasons, including software updates, changes in hardware, or 33 00:02:38,600 --> 00:02:40,310 evolving user interactions. 34 00:02:40,340 --> 00:02:46,820 Degradation can manifest as increased error rates, slower response times, or reduced user satisfaction. 35 00:02:47,210 --> 00:02:53,180 For example, a recommendation system for an e-commerce platform might start suggesting less relevant 36 00:02:53,180 --> 00:02:58,850 products if it is not periodically updated with new purchasing trends and user preferences. 37 00:03:00,200 --> 00:03:05,300 Establishing key performance indicators that align with the systems objectives can help in tracking 38 00:03:05,300 --> 00:03:07,010 its health and effectiveness. 39 00:03:07,430 --> 00:03:12,680 Regular performance reviews and user feedback can provide valuable insights for timely maintenance and 40 00:03:12,680 --> 00:03:13,640 improvements. 41 00:03:16,040 --> 00:03:21,290 Beyond technical performance, ethical considerations play a vital role in post-deployment tracking. 42 00:03:21,320 --> 00:03:27,280 The ethical implications of AI systems extend to privacy, transparency, and accountability. 43 00:03:27,310 --> 00:03:33,520 Ensuring that AI systems adhere to ethical standards requires continuous oversight and governance. 44 00:03:33,910 --> 00:03:39,910 For instance, data privacy regulations such as the General Data Protection Regulation mandate stringent 45 00:03:39,910 --> 00:03:42,160 measures for handling personal data. 46 00:03:42,640 --> 00:03:47,980 AI systems must be designed and monitored to comply with these regulations, preventing unauthorized 47 00:03:47,980 --> 00:03:49,870 data access and misuse. 48 00:03:50,260 --> 00:03:55,960 Transparency is also crucial as it fosters trust and allows stakeholders to understand the decision 49 00:03:55,990 --> 00:03:58,270 making processes of AI systems. 50 00:03:58,690 --> 00:04:04,330 Implementing explainable AI techniques can enhance transparency by providing clear and interpretable 51 00:04:04,330 --> 00:04:07,750 insights into how the system arrives at specific decisions. 52 00:04:09,820 --> 00:04:14,860 Regulatory compliance is integral to the post-deployment tracking of AI systems. 53 00:04:15,280 --> 00:04:21,460 Governments and regulatory bodies are increasingly recognizing the need for robust AI governance frameworks. 54 00:04:21,880 --> 00:04:27,850 These frameworks often include guidelines and standards for AI system performance, safety, and ethics. 55 00:04:28,480 --> 00:04:33,940 For instance, the European Commission's proposed Artificial Intelligence Act outlines requirements 56 00:04:33,940 --> 00:04:39,940 for high risk AI systems, including continuous monitoring and reporting of performance metrics. 57 00:04:40,330 --> 00:04:45,520 Compliance with such regulations necessitates a comprehensive approach to tracking that encompasses 58 00:04:45,520 --> 00:04:49,090 data management, audit trails, and documentation. 59 00:04:49,570 --> 00:04:56,350 Organizations must establish processes to ensure that their AI systems meet the regulatory requirements, 60 00:04:56,350 --> 00:05:00,280 and are prepared for audits and assessments by external authorities. 61 00:05:01,900 --> 00:05:06,910 Real world examples underscore the importance of effective post-deployment tracking. 62 00:05:07,690 --> 00:05:13,300 The case of Compas, a risk assessment tool used in the US criminal justice system, highlights the 63 00:05:13,300 --> 00:05:16,390 potential consequences of inadequate monitoring. 64 00:05:16,750 --> 00:05:22,780 Studies revealed that Compas exhibited significant racial bias, with higher false positive rates for 65 00:05:22,780 --> 00:05:25,810 African American defendants compared to white defendants. 66 00:05:26,590 --> 00:05:32,440 This finding sparked widespread criticism and underscored the need for rigorous post-deployment evaluation 67 00:05:32,440 --> 00:05:34,540 to identify and address such issues. 68 00:05:35,140 --> 00:05:41,260 Another example is the use of AI in predictive policing, where biased data can lead to disproportionate 69 00:05:41,290 --> 00:05:43,300 targeting of certain communities. 70 00:05:43,480 --> 00:05:49,240 Continuous performance tracking and bias audits are essential to mitigate these risks and ensure that 71 00:05:49,270 --> 00:05:52,450 AI systems contribute positively to society. 72 00:05:54,340 --> 00:06:00,310 In conclusion, tracking AI system performance post-deployment is a multifaceted endeavor that encompasses 73 00:06:00,310 --> 00:06:03,340 technical, ethical, and regulatory dimensions. 74 00:06:03,640 --> 00:06:09,130 Addressing model drift bias, and system degradation is essential for maintaining the effectiveness 75 00:06:09,130 --> 00:06:11,470 and fairness of AI applications. 76 00:06:11,950 --> 00:06:17,770 Ethical considerations, including privacy, transparency, and accountability, must be integrated 77 00:06:17,770 --> 00:06:22,750 into the monitoring processes to uphold public trust and compliance with regulations. 78 00:06:23,020 --> 00:06:28,270 Real world examples demonstrate the critical need for ongoing oversight to prevent adverse outcomes 79 00:06:28,270 --> 00:06:32,650 and ensure that AI systems operate in alignment with societal values. 80 00:06:33,190 --> 00:06:39,520 As AI technologies continue to evolve, robust post-deployment tracking mechanisms will be indispensable 81 00:06:39,520 --> 00:06:43,360 for fostering responsible and sustainable AI deployment.
