The Common Misconceptions About Machine Learning - KDnuggets
There is a hype train going on about ML (Machine Learning), and many beginners are getting to be the victims of this hype train as they are getting in for the wrong reasons. Your professor will explain how getting a Ph.D. is necessary if you want to get better or your peers are telling you how to get a better GPU and IDE (Integrated Development Environment). When you started to learn from the online courses, you realized you needed a bigger dataset and proficiency in Python. After learning the required skills when you applied for a job, you realized that you need more than a few courses or certifications to make it. In the end, after getting the job, you realized that it is demanding work, and sometimes these jobs don't pay well at the initial stages. This article will help you get through these disappointments and prepare you to face these problems.

Solving Linear Algebra by Program Synthesis
We solve MIT's Linear Algebra 18.06 course and Columbia University's Computational Linear Algebra COMS3251 courses with perfect accuracy by interactive program synthesis. This surprisingly strong result is achieved by turning the course questions into programming tasks and then running the programs to produce the correct answers. We use OpenAI Codex with zero-shot learning, without providing any examples in the prompts, to synthesize code from questions. We quantify the difference between the original question text and the transformed question text that yields a correct answer. Since all COMS3251 questions are not available online the model is not overfitting. We go beyond just generating code for questions with numerical answers by interactively generating code that also results visually pleasing plots as output. Finally, we automatically generate new questions given a few sample questions which may be used as new course content. This work is a significant step forward in solving quantitative math problems and opens the door for solving many university level STEM courses by machine.
Randomized Classifiers vs Human Decision-Makers: Trustworthy AI May Have to Act Randomly and Society Seems to Accept This
Erdรฉlyi, Gรกbor, Erdรฉlyi, Olivia J., Estivill-Castro, Vladimir
As \emph{artificial intelligence} (AI) systems are increasingly involved in decisions affecting our lives, ensuring that automated decision-making is fair and ethical has become a top priority. Intuitively, we feel that akin to human decisions, judgments of artificial agents should necessarily be grounded in some moral principles. Yet a decision-maker (whether human or artificial) can only make truly ethical (based on any ethical theory) and fair (according to any notion of fairness) decisions if full information on all the relevant factors on which the decision is based are available at the time of decision-making. This raises two problems: (1) In settings, where we rely on AI systems that are using classifiers obtained with supervised learning, some induction/generalization is present and some relevant attributes may not be present even during learning. (2) Modeling such decisions as games reveals that any -- however ethical -- pure strategy is inevitably susceptible to exploitation. Moreover, in many games, a Nash Equilibrium can only be obtained by using mixed strategies, i.e., to achieve mathematically optimal outcomes, decisions must be randomized. In this paper, we argue that in supervised learning settings, there exist random classifiers that perform at least as well as deterministic classifiers, and may hence be the optimal choice in many circumstances. We support our theoretical results with an empirical study indicating a positive societal attitude towards randomized artificial decision-makers, and discuss some policy and implementation issues related to the use of random classifiers that relate to and are relevant for current AI policy and standardization initiatives.
Target Layer Regularization for Continual Learning Using Cramer-Wold Generator
Mazur, Marcin, Pustelnik, ลukasz, Knop, Szymon, Pagacz, Patryk, Spurek, Przemysลaw
The concept of continual learning (CL), which aims to reduce the distance between human and artificial intelligence, seems to be considered recently by deep learning community as one of the main challenges. Generally speaking, it means the ability of the neural network to effectively learn consecutive tasks (in either supervised or unsupervised scenarios) while trying to prevent forgetting already learned information. Therefore, when designing an appropriate strategy, it needs to be ensured that the network weights are updated in such a way that they correspond to both the current and all previous tasks. However, in practice, it is quite likely that constructed CL model will suffer from either intransigence (hard acquiring new knowledge, see Chaudhry et al. [2018]) or catastrophic forgetting (CF) phenomenon (tendency to lose past knowledge, see McCloskey and Cohen [1989]). In recent years, methods of overcoming the above-mentioned problems are subject to wide and intensive investigation.
Learning Representations for Pixel-based Control: What Matters and Why?
Tomar, Manan, Mishra, Utkarsh A., Zhang, Amy, Taylor, Matthew E.
Learning representations for pixel-based control has garnered significant attention recently in reinforcement learning. A wide range of methods have been proposed to enable efficient learning, leading to sample complexities similar to those in the full state setting. However, moving beyond carefully curated pixel data sets (centered crop, appropriate lighting, clear background, etc.) remains challenging. In this paper, we adopt a more difficult setting, incorporating background distractors, as a first step towards addressing this challenge. We present a simple baseline approach that can learn meaningful representations with no metric-based learning, no data augmentations, no world-model learning, and no contrastive learning. We then analyze when and why previously proposed methods are likely to fail or reduce to the same performance as the baseline in this harder setting and why we should think carefully about extending such methods beyond the well curated environments. Our results show that finer categorization of benchmarks on the basis of characteristics like density of reward, planning horizon of the problem, presence of task-irrelevant components, etc., is crucial in evaluating algorithms. Based on these observations, we propose different metrics to consider when evaluating an algorithm on benchmark tasks. We hope such a data-centric view can motivate researchers to rethink representation learning when investigating how to best apply RL to real-world tasks.
Artificial intelligence is getting better at writing, and universities should worry about plagiarism
The dramatic rise of online learning during the COVID-19 pandemic has spotlit concerns about the role of technology in exam surveillance -- and also in student cheating. Some universities have reported more cheating during the pandemic, and such concerns are unfolding in a climate where technologies that allow for the automation of writing continue to improve. Over the past two years, the ability of artificial intelligence to generate writing has leapt forward significantly, particularly with the development of what's known as the language generator GPT-3. With this, companies such as Google, Microsoft and NVIDIA can now produce "human-like" text. AI-generated writing has raised the stakes of how universities and schools will gauge what constitutes academic misconduct, such as plagiarism.
