As we believe that discussions of AI tend to be long on jargon/ Target 200.00 205.00 short on substance, our aim with this report is to take a deep dive into Upside p 11.8% machine learning and deep learning, covering the theory behind deep Tencent Holdings (700 HK) learning algorithms and the real-world applications for machine learning.

Upside p 10.8% Baidu (BIDU US) Rating Hold Hold What's the impact: AI: it is here, almost unnoticed. Many investors may Target 215.00 195.00 not realise that machine learning and deep learning already serve as the Downside q 9.1% guiding hand in the Internet services they use daily. From search engines Source: Daiwa forecasts to content recommendations, Internet companies are folding machine- learning technology into their services with the aim of improving information discovery and monetisation efficiency. Proprietary data and disruptive business models: crucial to long-term success. We see proprietary data becoming the moat to defend against competition in the AI era, since it gives the owner exclusive insight into users’ behaviour and hence an opportunity to provide a superior experience. We believe the proliferation of machine learning will give rise to new disruptive economic models. Compared with their global peers, the China Internet players have more comprehensive proprietary data to hand, which we think will allow them to make the most of the emerging business opportunities. What we recommend: In our view, the Internet giants have natural capital and data advantages over start-ups in researching and deploying machine learning to their product lines. We see Baidu (BIDU US, USD236.41, Hold [3]) as the pioneer in AI investment and research in China. Although visibility on commercialisation of Baidu’s autonomous driving project is limited, we expect the initiative to significantly expand Baidu’s addressable market. Meanwhile, we contend that Alibaba (BABA US, USD178.97, Buy [1]) AI status is not fully appreciated, as it has been quietly folding machine learning into such products as the mobile Taobao app and Xiami music. Also, we think its cloud leadership will give it a cost advantage in AI training. Finally, Tencent (700 HK, HKD334.00, Buy [1]) looks to be raising its AI game, and its vast set of user data, allied with machine learning, should greatly enhance its ability to monetise online ads and digital payments, in our view. In this report, we revise our 12-month TPs for all 3 of China’s Internet giants. How we differ: We are more positive than the market on how machine learning will enhance the efficiency of Internet monetisation models.

  • Computer Wins Second GAME Against Chinese GO Champion
    TECHNOLOGY SATURDAY, MAY 27, 2017 Samsung investigating Galaxy S8 ‘iris hack’ SEOUL: Samsung Electronics is investigating claims by a German hacking group that it fooled the iris recognition system of the new flagship Galaxy S8 device, the firm said yesterday. The launch of the Galaxy S8 was a key step for the world’s largest smartphone maker as it sought to move on from last year’s humiliating withdrawal of the fire-prone Galaxy Note 7s, which hammered the firm’s once-stellar reputation. But a video posted by the Chaos Computer Club (CCC), a German hacking group founded in 1981, shows the Galaxy S8 being unlocked using a printed photo of the owner’s eye covered with a contact lens to replicate the curvature of a real eyeball. “A high- resolution picture from the internet is sufficient to cap- ture an iris,” CCC spokesman Dirk Engling said, adding: “Ironically, we got the best results with laser printers made by Samsung.” A Samsung spokeswoman said it was aware of the report and was investigating. The iris scanning technolo- gy was “developed through rigorous testing”, the firm said in a statement as it sought to reassure customers. “If there is a potential vulnerability or the advent of a new method that challenges our efforts to ensure security at WUZHEN: Chinese Go player Ke Jie, left, looks at the board as a person makes a move on behalf of Google’s artificial any time, we will respond as quickly as possible to resolve intelligence program, AlphaGo, during a game of Go at the Future of Go Summit in Wuzhen in eastern China’s Zhejiang the issue.” Samsung’s hopes of competing against archri- Province.

Any illustrations that are not the work of the author of this report have been used with the explicit permis- sion of the originator and are specifically acknowledged. I understand that failure to do this amounts to plagiarism and will be considered grounds for failure. Name: Yue Zheng Abstract Reinforcement learning has exceeded human-level performance in game playing AI with deep learning methods according to the experiments from DeepMind on Go and Atari games. Deep learning solves high dimension input problems which stop the development of reinforcement for many years. This study uses both two techniques to create several agents with different algorithms that successfully learn to play T-rex Runner. Deep Q network algorithm and three types of improvements are implemented to train the agent. The results from some of them are far from satisfactory but others are better than human experts. Batch normalization is a method to solve internal covariate shift problems in deep neural network. The positive influence of this on reinforcement learning has also been proved in this study. ii Acknowledgement I would like to express many thanks to my supervisor, Prof.

Intelligence (AI). Recent developments in machine learning have We take a black-box approach that ignores some dimensions allowed a few AI systems to win against top professionals in even the most challenging video games, including Dota 2 and of fairness such as learning speed and prior knowledge, StarCraft. It thus may seem that AI has now achieved all of focusing only on perceptual and motoric fairness. Additionally, the long-standing goals that were set forth by the research we introduce the notions of game extrinsic factors, such as the community. In this paper, we introduce a black box approach competition format and rules, and game intrinsic factors, such that provides a pragmatic way of evaluating the fairness of AI vs. as different mechanical systems and configurations within one human competitions, by only considering motoric and perceptual fairness on the competitors’ side.

The highest performing algorithm was used in a challenge against human players, with the goal of at least playing on human level. The most successful algorithm was a Monte Carlo search algorithm which spend time, before a round, playing out the entire game from that round many times. Another successful algorithm was linear combination of features, which spend time before the battle playing many training games in order to adjust weights correlating to actions and the game state. In addition, the random algorithm which always picks a random action and the hard coded algorithm which picks a pre-defined action each round was used as benchmark algorithms for the different scenarios.
