Robust Imitation Learning from Noisy Demonstrations
Tangkaratt, Voot, Charoenphakdee, Nontawat, Sugiyama, Masashi
The goal of sequential decision making is to learn a good policy that makes good decisions (Puterman, 1994). Imitation learning (IL) is an approach that learns a policy from demonstrations (i.e., sequences of demonstrators' decisions) (Schaal, 1999). Researchers have shown that a good policy can be learned efficiently from high-quality demonstrations collected from experts (Ng and Russell, 2000; Syed et al., 2008; Ziebart et al., 2010; Ho and Ermon, 2016; Sun et al., 2019). However, demonstrations in the realworld often have lower quality due to noise or insufficient expertise of demonstrators, especially when humans are involved in the data collection process (Mandlekar et al., 2018). This is problematic because low-quality demonstrations can reduce the efficiency of IL both in theory and practice (Tangkaratt et al., 2020). In this paper, we theoretically and experimentally show that IL can perform well even in the presence of noises.
Mitigating Gender Bias for Neural Dialogue Generation with Adversarial Learning

Given messages The elimination of discrimination is an important with the same content for different genders, issue that our society is facing. Learning from dialogue models could produce biased responses, human behaviors, machine learning algorithms which have been measured in terms of their politeness have been proven to inherit the prejudices from and sentiment, as well as the existence of humans (Mehrabi et al., 2019). A variety of AI applications biased words (Liu et al., 2019a). Table 1 shows one have demonstrated common prejudices example from a generative dialogue model trained towards particular groups of people (Rodger and on the Twitter dialogue corpus. When we change Pendharkar, 2004; Howard and Borenstein, 2018; the words in the message from "he" to "she", the responses Rose, 2010; Yao and Huang, 2017; Tolan et al., produced by the dialogue model are quite 2019). It is evident from recent research that different. In particular, the dialogue model generates learning-based dialogue systems also suffer from responses with negative sentiments for females.
Why is Python so popular among Data Scientists?
The ability to extract insights from massive amounts of data decides your enterprise's success. This is where data scientists and analysts interpret data and derive insights to help identify opportunities and make strategic decisions. For effective analysis of data, data scientists need to be equipped with the best tools for analyzing, reporting, and visualization. Languages such as C, C, Java and Javascript help understand data. That's a tricky question to answer.
Types of Regularization Techniques To Avoid Overfitting
Regularization is a set of techniques which can help avoid overfitting in neural networks, thereby improving the accuracy of deep learning models when it is fed entirely new data from the problem domain. There are various regularization techniques, some of the most popular ones are -- L1, L2, dropout, early stopping, and data augmentation. The characteristic of a good machine learning model is its ability to generalise well from the training data to any data from the problem domain; this allows it to make good predictions on the data that model has never seen. To define generalisation, it refers to how well the model has learnt the concepts to apply to any data rather than just with the specific data it was trained on during the training process. On the flip side, if the model is not generalised, a problem of overfitting emerges.
MIT Uses Artificial Intelligence to Identify Powerful New Antibiotic
MIT researchers have identified a powerful new antibiotic compound using a machine-learning algorithm. A deep-learning model identifies a powerful new drug that can kill many species of antibiotic-resistant bacteria. Using a machine-learning algorithm, MIT researchers have identified a powerful new antibiotic compound. In laboratory tests, the drug killed many of the world's most problematic disease-causing bacteria, including some strains that are resistant to all known antibiotics. It also cleared infections in two different mouse models.
Prediction for Overheating Risk Based on Deep Learning in a Zero Energy Building
The Passive House standard has become the standard for many countries in the construction of the Zero Energy Building (ZEB). Korea also adopted the standard and has achieved great success in building energy savings. However, some issues remain with ZEBs in Korea. Among them, this study aims to discuss overheating issues. Field measurements were carried out to analyze the overheating risk for a library built as a ZEB. A data-driven overheating risk prediction model was developed to analyze the overheating risk, requiring only a small amount of data and extending the analysis throughout the year. The main factors causing overheating during both the cooling season and the intermediate seasons are also analyzed in detail. The overheating frequency exceeded 60% of days in July and August, the midsummer season in Korea. Overheating also occurred during the intermediate seasons when air conditioners were off, such as in May and October in Korea. Overheating during the cooling season was caused mainly by unexpected increases in occupancy rate, while overheating in the mid-term was mainly due to an increase in solar irradiation. This is because domestic ZEB standards define the reinforcement of insulation and airtight performance, but there are no standards for solar insolation through windows or for internal heat generation. The results of this study suggest that a fixed performance standard for ZEBs that does not reflect the climate or cultural characteristics of the region in which a ZEB is built may not result in energy savings at the operational stage and may not guarantee the thermal comfort of occupants.
I Asked AI to Write This Post for Me. Here Are the Results.
In June 2020 an Artificial Intelligence system called GPT-3 went live. This AI model is focused on Natural Language Programming and was trained by reading trillions of words and sentences online. The net result is that it can generate impressive text that humans can barely tell was created by a computer. A growing number of developers are being given access to GPT-3 to create real-world applications. In the coming months, you are going to start to see a plethora of AI applications that create content such as blogs, articles, reports, emails, advertising copy, and sales scripts.
(November 6 & 13, 2020) Artificial Intelligence on Water Resources - TheWaterChannel
In recent years the increase of machine learning applications to water resources have allowed us to propose new solutions to complex problems. Alumni from the Hydroinformatics program have explored new areas that in many cases have led to implementations at different places in the world, and have shown to be able to compete with ongoing traditional solutions. For this seminar we will make an overview of some of the most recent ideas of applications of machine learning in Hydroinformatics. These presentations will be divided into two sessions that will cover forecasting problems. An introduction in both sessions to a variety of machine learning basic concepts will be given to introduce the topics, limitations and a friendly way to see the theory.
