#ICML2023 invited talk: Jennifer Doudna on machine learning for biological research
The programme of the International Conference on Machine Learning (ICML) featured an invited talk by Jennifer Doudna entitled "The future of ML in biology: CRISPR for health and climate". Jennifer Doudna and Emmanuelle Charpentier won the 2020 Nobel Prize in Chemistry for "the development of a method for genome editing". The method in question is often referred to as CRISPR/Cas9 genetic scissors. Using this technique, researchers can change the DNA of animals, plants and microorganisms with extremely high precision. This technology has already had a huge impact on the biological sciences.
Comparing How a Chatbot References User Utterances from Previous Chatting Sessions: An Investigation of Users' Privacy Concerns and Perceptions
Cox, Samuel Rhys, Lee, Yi-Chieh, Ooi, Wei Tsang
Chatbots are capable of remembering and referencing previous conversations, but does this enhance user engagement or infringe on privacy? To explore this trade-off, we investigated the format of how a chatbot references previous conversations with a user and its effects on a user's perceptions and privacy concerns. In a three-week longitudinal between-subjects study, 169 participants talked about their dental flossing habits to a chatbot that either, (1-None): did not explicitly reference previous user utterances, (2-Verbatim): referenced previous utterances verbatim, or (3-Paraphrase): used paraphrases to reference previous utterances. Participants perceived Verbatim and Paraphrase chatbots as more intelligent and engaging. However, the Verbatim chatbot also raised privacy concerns with participants. To gain insights as to why people prefer certain conditions or had privacy concerns, we conducted semi-structured interviews with 15 participants. We discuss implications from our findings that can help designers choose an appropriate format to reference previous user utterances and inform in the design of longitudinal dialogue scripting.
AttentionViz: A Global View of Transformer Attention
Yeh, Catherine, Chen, Yida, Wu, Aoyu, Chen, Cynthia, Viรฉgas, Fernanda, Wattenberg, Martin
Figure 1: AttentionViz, our interactive visualization tool, allows users to explore transformer self-attention at scale by creating a joint embedding space for queries and keys. Each point in the scatterplot represents the query or key version of a word, as denoted by point color. Users can explore individual attention heads (left) or zoom out for a "global" view of attention (right). Abstract--Transformer models are revolutionizing machine learning, but their inner workings remain mysterious. In this work, we present a new visualization technique designed to help researchers understand the self-attention mechanism in transformers that allows these models to learn rich, contextual relationships between elements of a sequence. The main idea behind our method is to visualize a joint embedding of the query and key vectors used by transformer models to compute attention. Unlike previous attention visualization techniques, our approach enables the analysis of global patterns across multiple input sequences. We create an interactive visualization tool, AttentionViz (demo: http://attentionviz.com), based on these joint query-key embeddings, and use it to study attention mechanisms in both language and vision transformers. We demonstrate the utility of our approach in improving model understanding and offering new insights about query-key interactions through several application scenarios and expert feedback. The transformer neural network architecture [52] is having a major impact In this work, we describe a new visualization technique aimed at on fields ranging from natural language processing (NLP) [13, 42] better comprehending how transformers operate. Indeed, transformers are now deployed in introduction to transformers in Sec. However, the mechanisms these models to learn and use a rich set of relationships between input behind this success remain somewhat mysterious, especially as elements.
Let's have a chat! A Conversation with ChatGPT: Technology, Applications, and Limitations
Shahriar, Sakib, Hayawi, Kadhim
In 1950, the British computer scientist Alan Turing disputed whether human reasoning can be matched by computers: "Can machines think?" (TURING, 1950). Subsequently, he proposed the Turing Test to measure computer or artificial intelligence. In a Turing test, a human interrogator is presented with responses from a human and a computer (with the ability to generate written texts in real-time). If the interrogator cannot distinguish between the answers, the computer system passes the Turing Test. Although several computer programs and chatbots like Eliza demonstrated success in the Turing test ((Weizenbaum, 1966) (Gรผzeldere & Franchi, 1995)), these programs arguably used certain tricks to pass the test (Pinar Saygin et al., 2000) rather than demonstrating any significant intelligence. With the advancement in machine learning and natural language processing (NLP), chatbots have gained significant research attention and have been used for a variety of commercial and non-commercial applications ((Luo et al., 2022), (Adamopoulou & Moussiades, 2020), (Ranoliya et al., 2017), (Rahman et al., 2017), (Zhou et al., 2020)). Despite their vast adoption, most chatbots do not have personalization, and user satisfaction remains questionable (Fรธlstad & Brandtzaeg, 2020). This limitation prompted researchers and developers to focus on chatbot engagement in making chatbots more conversational.
The Creative Ways Teachers Are Using ChatGPT in the Classroom
Peter Paccone, a social studies teacher in San Marino, Calif., has a new teacher's aid helping him in the classroom this year. He plans to defer to his helper to explain some simpler topics to his class of high schoolers, like the technical aspects of how a cotton gin worked, in order to free up time for him to discuss more analytical concepts, like the effects of the first industrial revolution. "What I feel that I don't have to do any longer is cover all the content," Paccone told a group of more than 40 educators in a May Zoom workshop, which he organized. If artificial intelligence is on the cusp of reshaping entire aspects of our society--from healthcare to warfare--the first realm that leaps to many minds is education: Asked a question online, the ChatGPT chatbot will produce an answer that reads like an essay. So as students and teachers prepare for a new school year, they are also grappling with AI's implications for learning, homework, and integrity.
Grimes on Living Forever, Dying on Mars, and Giving Elon Musk Ideas for His Best (Worst) Tweets
I thought my interview with Grimes--the mysterious techno artist, fan of all nerddom, and the deepest of insiders in Elon Musk's world--would be one-on-one. Instead it wound up as a roundtable discussion. Turns out there are multiple personas embedded in the surprisingly haimish human who sat under a tree with me and spent the waning hours of an afternoon in conversation. There was Claire Boucher, the given name of a Vancouver kid obsessed with video games and devoted to provoking adults with misbehavior and the embrace of taboo subjects. There was Grimes, the self-invented, scrappy DIY musician and provocateur who weaves sci-fi into her work and released what Pitchfork judged to be the second-best song of the 2010s.
Why Data Science Projects Fail
Data Science is a modern Data Intelligence practice, which is the core of many businesses and helps businesses build smart strategies around to deal with businesses challenges more efficiently. Data Science practice also helps in automating business processes using the algorithm, and it has several other benefits, which also deliver in a non-profitable framework. In regards to data science, three key components primarily influence the effective outcome of a data science project. Those are 1.Availability of Data 2.Algorithm 3.Processing power or infrastructure
AI language models are rife with political biases
The researchers asked language models where they stand on various topics, such as feminism and democracy. They used the answers to plot them on a graph known as a political compass, and then tested whether retraining models on even more politically biased training data changed their behavior and ability to detect hate speech and misinformation (it did). The research is described in a peer-reviewed paper that won the best paper award at the Association for Computational Linguistics conference last month. As AI language models are rolled out into products and services used by millions of people, understanding their underlying political assumptions and biases could not be more important. That's because they have the potential to cause real harm.
Studying Large Language Model Generalization with Influence Functions
Grosse, Roger, Bae, Juhan, Anil, Cem, Elhage, Nelson, Tamkin, Alex, Tajdini, Amirhossein, Steiner, Benoit, Li, Dustin, Durmus, Esin, Perez, Ethan, Hubinger, Evan, Lukoลกiลซtฤ, Kamilฤ, Nguyen, Karina, Joseph, Nicholas, McCandlish, Sam, Kaplan, Jared, Bowman, Samuel R.
When trying to gain better visibility into a machine learning model in order to understand and mitigate the associated risks, a potentially valuable source of evidence is: which training examples most contribute to a given behavior? Influence functions aim to answer a counterfactual: how would the model's parameters (and hence its outputs) change if a given sequence were added to the training set? While influence functions have produced insights for small models, they are difficult to scale to large language models (LLMs) due to the difficulty of computing an inverse-Hessian-vector product (IHVP). We use the Eigenvalue-corrected Kronecker-Factored Approximate Curvature (EK-FAC) approximation to scale influence functions up to LLMs with up to 52 billion parameters. In our experiments, EK-FAC achieves similar accuracy to traditional influence function estimators despite the IHVP computation being orders of magnitude faster. We investigate two algorithmic techniques to reduce the cost of computing gradients of candidate training sequences: TF-IDF filtering and query batching. We use influence functions to investigate the generalization patterns of LLMs, including the sparsity of the influence patterns, increasing abstraction with scale, math and programming abilities, cross-lingual generalization, and role-playing behavior. Despite many apparently sophisticated forms of generalization, we identify a surprising limitation: influences decay to near-zero when the order of key phrases is flipped. Overall, influence functions give us a powerful new tool for studying the generalization properties of LLMs.
Is Congress Moving Too Slowly on A.I.?
At a White House summit on July 21, the Biden administration brought together the heads of seven different A.I. companies. A lot of the big names were there--Meta, Google, OpenAI--and they all signed "voluntary commitments" to safeguard artificial intelligence. In the Senate, Chuck Schumer is proposing a framework that legislators can use to tackle A.I. issues. But while the A.I. industry is moving at a breakneck pace, Washington is, as usual, slow to regulate. On Friday's episode of What Next: TBD, I spoke with Makena Kelly, who covers politics and policy for the Verge, about whether Washington can keep up with A.I. Our conversation has been edited and condensed for clarity.
